Definitions
- the present invention relates to a method for knitting a fabric and a design device to, in intarsia patterns, floating stitches, and the like, capture a knitting yarn in the hook of a knitting needle when the knitting yarn is let loose to avoid engagement in the knitting needle and be fed as a cross-over yarn.
- a flat knitting machine is used to knit fabrics including an intarsia pattern and the like by changing over a plurality of knitting yarns in the same knitting course (for example, see Patent Citation 1).
- Knitting yarns used for knitting fabrics on flat knitting machines are fed to knitting needles from a yarn feeding member such as a yarn carrier, which moves along a needle bed gap in cooperation with the fabric knitting operation of the knitting needles.
- the intarsia pattern and the like to be knitted are in the form of being fitted in the fabric serving as a ground. Consequently, at the start portion and the end portion of the intarsia pattern and the like, yarn in and yarn out of a knitting yarn different from the ground fabric are carried out.
- the position of yarn feeding from a yarn carrier and the like floats from the needle bed gap at the end part where knitting of an intarsia pattern and the like starts, thereby making it difficult to capture the fed knitting yarn in the hook of the knitting needle.
- the cross-over yarn might be erroneously captured in a knitting needle that is knitting the fabric and thus be knitted into the fabric or might be entangled to the detriment of the knitting operation.
- the problem of floating of the cross-over yarn from the needle bed gap and difficulty in capturing in the knitting needle occurs not only in the intarsia-pattern knitting but also in fabrics of the floating stitch.
- processing is carried out as knitting the cross-over yarn into the fabric such as by a tuck in the cross-over section, thus preventing the cross-over yarn from floating from the needle bed gap.
- knitting the cross-over yarn into the fabric by a tuck and the like requires the work of removing the knitted cross-over yarn portion in the subsequent process.
- a yarn processing method and a knitting method that temporarily capture the knitting yarn to be a cross-over yarn with the use of knitting needles in the cross-over section and release the captured cross-over yarn after knitting of a plurality of courses (see, for example, Patent Citations 2 and 3).
- the cross-over yarn floats from the needle bed gap. Therefore, when the cross-over section is elongated, the number of capturing knitting needles must be increased.
- a method for capturing the cross-over yarn such that instead of engaging the cross-over yarn in the hook of the knitting needle, the knitting needle is guided to the lower side of the hook and held (see, for example, Patent Citation 4).
- the requisite of this method is that the movements of the knitting needle and yarn feeding member are individually controllable, which necessitates mounting of a new cam mechanism in the flat knitting machines, by which fabrics are knitted while moving a carriage mounting therein a cam mechanism along the needle bed gap with the accompaniment of the yarn carrier.
- the present invention provides a method for knitting a fabric on a flat knitting machine provided with at least a pair of front and rear needle beds opposed to one another across a needle bed gap, each of the needle beds being provided with a multiplicity of latch needles as knitting needles, which comprises:
- the held stitch loop is transferred to the knitting needle of the one needle bed from a fabric belonging to the other needle bed; and after the split knit, the newly formed stitch loop is removed from the knitting needle of the one needle bed.
- the knitting yarn is used for knitting an inner area of the fabric and becomes the cross-over yarn during yarn out; the split knit is carried out in the vicinity of an end portion of the fabric; and after the split knit, the newly formed stitch loop is removed from the knitting needle of the other needle bed after knitting of a predetermined number of courses.
- the stitch loop newly formed by the split stitch is removed from the knitting needle of the one needle bed after, subsequent to the split stitch, a stitch is formed on a knitting needle different from the knitting needle used for the split stitch.
- the stitch loop subjected to the split stitch into the knitting needle of the other needle bed, or a stitch loop knitted following the split stitch loop is transferred to the one needle bed side to stop ravel.
- the knitting yarn is fed in such a manner that the knitting yarn becomes the cross-over yarn from a portion kitted before the plurality of courses of the fabric; in a knitting course where the split knit is carried out, a portion where the knitting yarn crosses between the needle beds is formed in the vicinity of the end portion of the fabric; and the crossing portion is released after the cross-over yarn is fed in and captured in the knitting needle carrying out the split knit through the crossing portion.
- the present invention provides a design device of a fabric for creating knitting data to knit a fabric on a flat knitting machine, the flat knitting machine being provided with at least a pair of front and rear needle beds opposed to one another across a needle bed gap, each of the needle beds being provided with a multiplicity of latch needles as knitting needles, the knitting data created by the design device causing the flat knitting machine to execute a method which comprises; carrying out a split knit of a stitch loop held in the knitting needle of the one needle bed into a knitting needle of the other needle bed; and capturing a knitting yarn as a newly formed knitting loop in a hook of a knitting needle of the one needle bed, the knitting yarn serving as a cross-over yarn by being let loose over a distance so as to avoid engagement of the knitting yarn in knitting needles, the distance makes it difficult to capture the knitting yarn in a hook of a knitting needle which independently carrying out a stitch forming operation.
- a multiplicity of latch needles are disposed on a pair of front and rear needle beds as knitting needles, and even the knitting yarn in the cross-over yarn state floating from the needle bed gap is guided inside the hook when a split stitch between the needle beds causes the stitch loop subjected to the split into an opposite needle bed to close the latch in the needle bed gap, thereby making it possible to surely capture the knitting yarn.
- the knitting yarn is definitely captured and knit a stable fabric.
- the stitch loop subjected to the split stitch is one that is transferred in advance from the needle bed to which the fabric belongs to the opposite needle bed, which makes it possible to return the transferred stitch loop to the original needle bed side as the split stitch.
- the new stitch loop is removed from the knitting needle to which the transfer was carried out, thereby eliminating the need for processing of the stitch loop newly formed by the split stitch in a subsequent process.
- the cross-over yarn is surely captured in the hook of the knitting needle in the vicinity of the end portion of the fabric, and in predetermined course knitting, the cross-over yarn is able to be held to prevent it from floating between the needle bed gap.
- the stitch loop newly formed by the split stitch is removed after a stitch loop following the split stitch is formed on a knitting needle different from the knitting needle of the stitch loop that was used for the split stitch.
- the stitch loop follows the split stitch can be returned to the split starting side by transfer instead of being removed so as to be utilized effectively to prevent a ravel.
- the state in which the knitting yarn fed in a state of a cross-over yarn, which avoids engagement in the knitting needle, floats from the needle bed gap varies depending on differences in the position of a portion of the knitting yarn where the preceding knitting course finished.
- a portion where the knitting yarn crosses the needle beds is formed, and therefore, the cross-over yarn is fed to the knitting needle that carries out the split stitch through the crossing portion.
- the crossing portion is rendered a starting point of yarn feeding to have a uniform condition for capturing the knitting yarn in the hook of the knitting needle, thereby making it possible to ensure the capture.
- knitting data can be created in such a manner that when a knitting yarn not engaged in the knitting needle becomes a cross-over yarn by floating from the needle bed gap, such knitting yarn can be surely captured in the hook of the knitting needle by split stitch.
- Fig. 1 is one embodiment of the present invention showing a state in which a knitting yarn is captured in the hook of a knitting needle with the use of a knitting operation of split stitch.
- a driving mechanism of knitting needles 3 and 4 is provided that is capable of, while transferring a stitch loop formed in the preceding course between the needle beds, forming a new stitch loop also on the knitting needle on the stitch-transferring side.
- the front needle bed 1 and the rear needle bed 2 are opposed to one another across a needle bed gap 5, and able to advance and retire the tip sides of the knitting needles 3 and 4 back and forth with respect to the needle bed gap 5.

- the knitting needle 3 at its midpoint is provided with a clip 3c.
- a yarn carrier 6 is movably provided in a direction perpendicular to the paper surface and feeds knitting yarn 7 through a yarn feeding port at the distal end.
- a stitch loop 8 is formed by the knitting operation of the knitting needles 3 and 4, and as the knitting proceeds, the stitch loop 8 parts from the knitting needles 3 and 4 to form a fabric 9 and hangs below the needle bed gap 5 by dead weight and various kinds of biasing.
- a new stitch loop is also formed on the hook 3a of the knitting needle 3 from a knitting yarn 7 fed from the yarn carrier 6.
- Fig. 1(a) shows a state in which after the stitch loop 8 is held at the clip 3c portion of the knitting needle 3 of the front needle bed 1 and is allowed to advance to the needle bed gap 5, the hook 4a of the knitting needle 4 of the rear needle bed 2 is allowed to go into the clip 3c portion and the stitch loop 8 is engaged in the hook 4a.
- the stitch loop 8 parts from the clip 3c and comes close to the tip of the latch 3b in an open state, since the stitch loop 8 is engaged in the hook 4a of the knitting needle 4 of the rear needle bed 2.
- the portion of the stitch loop 8 engaged in the knitting needle 3 comes around the tip of the knitting needle 3 along the circumferential portion of the latch 3b that is closing the hook 3a, thus parting from the knitting needle 3.
- the parting stitch loop 8 is engaged only in the hook 4a at the tip of the knitting needle 4 to end up as a stitch loop on the rear needle bed 2 side while being a knocked-over former loop for the stitch loop newly formed on the knitting needle 3.
- Fig. 2 shows one example of a cam system 10 that carries out the knitting operation to the knitting needle 3 of the front needle bed 1, which carries out transfer by the split stitch operation shown in Fig. 1 .
- this cam system is one of a plurality of sets mounted to the carriage along the needle bed gap 5, and is shown with the needle bed gap side upward.
- a portion closer to the needle bed gap may be indicated as “upper” and a portion away from the needle bed gap may be indicated as “lower”.
- a ground board 11 of the carriage facing the needle bed is provided with a stitch forming cam rock 15 including a needle raising cam 12 and stitch cams 13 and 14, and a stitch transferring cam rock 18 including a stitch receiving transfer cam 16 and a transfer cam 17 for both transfer and reception.
- the stitch cams 13 and 14 can be displaced along a direction parallel to slanted cam surfaces 13a and 14a so as to adjust the stitch density.
- the needle raising cam 12 has a lower fixed portion 19 and an upper movable portion 20.
- the movable portion 20 provided with a mechanism not shown, protrudes and recedes with respect to the ground board 11 alternately with the transfer cam 17 for both transfer and reception in such a manner that when one protrudes, the other recedes.
- the movable portion 20 is provided with a butt guiding groove 20a.
- the butt guiding groove 20a is bent in a mountainous form with its center portion approaching the needle bed gap side, and links to the slope of the fixed portion 19 through a horizontal shoulder portion 20b on both sides of the groove.
- the fixed portion 19 on its upper center portion is provided with the stitch receiving transfer cam 16 in a freely protruding/receding manner.
- the stitch receiving transfer cam 16 is symmetrical, both sides of which are inclined in such a manner that a portion closer to the center becomes deeper.
- the transfer cam 17 for both transfer and reception above the needle raising cam 12 is roughly in the form of mountainous triangles with two peaks disposed side by side. On the upper edge side, the transfer cam 17 guides a knitting needle butt on the stitch transferring side, and on the lower edge side, guides a knitting needle butt on the stitch receiving side. Above the transfer cam 17 for both transfer and reception, a transfer guide cam 21 is provided, on both sides of which continue needle guide cams 22.
- the movable portion 20 of the needle raising cam 12 is kept in the receding state as indicated by a chain double-dashed line while the transfer cam 17 for both transfer and reception is kept in the protruding state as indicated by a solid line.
- the knitting needles 3 and 4 are provided with two butts for receiving driving for the knitting operation by the cam system 10, with an upper butt 23 being acted upon by the stitch transferring cam rock 18 and a lower butt 24 being acted upon by the stitch forming cam rock 15. Assuming that the carriage provided with the cam system 10 runs leftward in the figure, the upper butt 23 and the lower butt 24 of the knitting needle 3 on the stitch transferring side move along the courses indicated by chain double-dashed lines.
- the positions of the upper butt 23 and the lower butt 24 corresponding to Fig. 1(a), 1(b), and 1(c) are respectively indicated by 23a, 23b, and 23c; 24a, 24b, and 24c.
- the position shown as the yarn carrier 6 is represented by the position at which the knitting yarn 7 from the yarn feeding port of the yarn carrier 6 is received in the hook 3a of the knitting needle 3.
- Fig. 3 shows a state in which the knitting needle 4 of the rear needle bed 2 is made to perform a knitting operation for a stitch receiving side by the split stitch operation shown in Fig. 1 with the use of the cam system 10 of Fig. 2 .
- the cam system 10 of Fig. 3 is mounted to the carriage of the rear needle bed 2. Therefore, for convenience of explanation, Fig. 3 is shown to be symmetrical to Fig. 2 with the needle bed gap side down. Corresponding portions in Figs. 2 and 3 are denoted by the same numerals and overlapping explanations will be omitted in Fig. 3 .
- the movable portion 20 of the needle raising cam 12 is kept in the receding state as indicated by a chain double-dash line while the transfer cam 17 for both transfer and reception is kept in the protruding state as indicated by a solid line.
- the knitting needle 4 is also acted upon by pressers 25, 26, and 27, though description of which is omitted in Fig. 2 .
- the cam system 10 selects the position of the knitting needle 4 among three positions to be acted upon by one of the pressers 25, 26, and 27, as disclosed in, for example, Fig. 1 of Japanese Examined Patent Application Publication No. H02-10262 .
- the knitting needles 3 and 4 are basically equivalent to those disclosed in Fig. 2 of Japanese Examined Patent Application Publication No. H02-10262 .
- the pressers 25, 26, and 27 can be individually switched into or out of action.
- the intermediate presser 27 is switched out of action as indicated by a chain double-dashed line.
- the pressers 25 and 26 are made to act upon the knitting needle 4
- the lower butt 24 of the knitting needle 4 is no longer acted upon by the fixed portion 19 but is acted upon by the stitch receiving transfer cam 17 at the center to advance to the needle bed gap side.
- the upper butt 23 comes in contact with the lower edge of the transfer cam 17 for both transfer and reception and descends along the guide surface formed on the lower edge.
- Fig. 4 shows a state in which the knitting needle 3 is made to perform a knitting operation of a knit with the use of the cam system 10 of Fig. 2 .
- the tip of the knitting needle 3 is temporarily advanced to the needle bed gap 5 to a clear position where the stitch loop 8 retracts behind the latch 3b.
- the stitch loop 8 that continues into the fabric 9 stays in the vicinity of the tip of the front needle bed 1, since the fabric 9 is biased below the needle bed gap 5.
- Fig. 4(a) shows a state in which the knitting needle 3 that was allowed to advance into the needle bed gap 5 to the clear position is pulled back to the front needle bed 1 and is fed a knitting yarn 7 from the yarn carrier 6. As shown in Fig.
- Fig. 5 shows a switching state of the cam system 10 when the knitting operation of a knit as shown in Fig. 4 is performed.
- the movable portion 20 of the needle raising cam 12 is kept in the protruding state as indicated by a solid line while the transfer cam 17 for both transfer and reception is kept in the receding state as indicated by a chain double-dashed line.
- the positions of the upper butt 23 and the lower butt 24 corresponding to Fig. 4(a), 4(b), and 4(c) are respectively indicated by 23a, 23b, and 23c; 24a, 24b, and 24c.
- the position shown as the yarn carrier 6 is represented by the position at which the knitting yarn 7 from the yarn feeding port of the yarn carrier 6 is received in the hook 3a of the knitting needle 3.
- Fig. 6 shows a simplified diagram of an example of the fabric 9.
- a pattern area 9xa of A is knitted
- a pattern area 9yb of B is knitted in a pattern area 9ya of A.
- a pattern area 9za of A is knitted in such fabric 9.
- processing of cross-over yarn is required at the time of yarn feeding at an edge portion 28 of the pattern area 9yb and at the time of yarn retrieval from an edge portion 29.
- Fig. 7 schematically shows a structure of a flat knitting machine 30 that knits the fabric 9.
- the front needle bed 1 is provided with a carriage 31 mounted with a cam system capable of knitting, transfer, split stitch, and the like.
- the carriage 31 selectively takes yarn carriers 6a and 6b that can travel along a yarn guide rail 32 provided above the needle gap, and travels reciprocatedly in the longitudinal direction of the needle bed. It is assumed that the pattern area of A of Fig. 6 is knitted with a knitting yarn 7a fed from the yarn carrier 6a and the pattern area of B is knitted with a knitting yarn 7b fed from the yarn carrier 6b.
- the knitting yarns 7a and 7b are fed from cones 33a and 33b disposed upright on a cone stand plate 33 to the yarn carriers 6a and 6b, respectively, at a substantially constant tension through a yarn tension device 34 and a yarn feeding device 35.
- a gripper 36 provided at the end portion of the needle bed.
- the end portion of the knitting yarn 7b is grasped by the gripper 36 until knitting of the edge portion 28 of the pattern area 9yb of the Y section starts.
- the need for capturing the knitting yarn 7 at a high position in the hook 3a occurs not only in knitting of intarsia patterns but also in floating stitches, where knitting is carried out after misses to the knitting needle are continued, and in the case where knitting of an area of an independent fabric such as a pocket newly starts in a fabric. Also in these cases, utilizing the split stitch can capture the knitting yarn 7 surely in the hook 3a.
- Figs. 8 , 9 , and 10 each show a state in which knitting of the X section in the wale direction is finished and knitting of the Y and Z sections for the fabric 9 of Fig. 6 is carried out.
- the numbers shown under "course" on the left side of each figure indicate relative course numbers. In the odd-number courses, the carriage runs leftward while in the even-number courses the carriage runs rightward.
- the symbols shown under "system” on the right side of each figure each show which cam system 10 is used when each carriage 31 mounts thereon three cam systems 10 such as those shown in Figs. 2 , 3 , and 5 .
- S1 indicates a system on the preceding side
- S2 indicates an intermediate system
- S3 indicates a system on the following side.
- the cam system 10 on the left side is designated as S1 and the cam system 10 on the right side is designated as S3 while when the carriage runs rightward, the cam system 10 on the right side is designated as S1 and the cam system 10 on the left side is designated as S3.
- the use of the cam system is shown by way of example.
- the numerical characters on and after the course 9 do not mean the courses on and after the 9th course relative to the course 1.
- the last course knitting in the X section in the wale direction is carried out by the knitting yarn 7a at the front needle bed 1.
- a stitch transfer is carried out from the front needle bed 1 to the rear needle bed 2 in the pattern area of A. This stitch transfer is for the purpose of forming a crossing portion in the needle bed gap 5 using the knitting yarn 7a.
- the position where the crossing portion is formed is preferably in the vicinity of the edge portion of the knitting width of the fabric 9.
- the first course knitting of the Y section in the wale direction starts.
- the yarn carrier 6b that feeds the knitting yarn 7b stands by on the left side of the front needle bed 1 as shown in Fig. 7 .
- the knitting yarn 7b links not to the gripper 36 but to the edge portion of the knitted pattern area of B, from the yarn feeding port at the distal end of the yarn carrier 6b.
- the yarn carrier 6b indicated as "b" is took rightward, the knitting yarn 7b is fed to the edge portion 28 of Fig. 6 after being engaged in the crossing portion formed in the course 1.
- split stitch is carried out. As described above, since the split stitch is used, even when the position of the knitting yarn 7b fed from the yarn carrier 6b is high, the knitting yarn 7b can be surely captured in the hook 3a of the knitting needle 3.
- the yarn carrier 6b runsa rightward by the system S1, and hooking to the rear needle bed 2 is transferred to the front needle bed 1 by the system S2.
- a tension to the knitting yarn 7b in the opposite direction by the system S1 and carrying out a stitch transfer by the system S2 relative to the hooking a twisted stitch can be formed at the edge portion of the pattern area side of A of the front needle bed 1.
- the yarn carrier 6b is advanced to the pattern area side of A by the system S1, and furthermore, a stitch transfer is carried out such that the stitch transferred to the knitting needle 4 of the rear needle bed 2 in the course 1 is returned to the knitting needle 3 of the front needle bed 1.
- a stitch transfer is carried out such that the stitch transferred to the knitting needle 4 of the rear needle bed 2 in the course 1 is returned to the knitting needle 3 of the front needle bed 1.
- the course knitting of the pattern area of B is carried out by hauling the yarn carrier 6b by the system S1.
- knitting of the pattern area of A is carried out by hauling the yarn carrier 6a by the system S2.
- the stitch loop that was subjected to the split stitch in the course 2 and is held in the knitting needle 4 of the rear needle bed 2 at the edge portion 28 of the pattern area of B is transferred to the knitting needle 3 of the front needle bed 1.
- ravel stopping can be carried out for the edge portion 28. Although this ravel stopping is carried out with the use of the stitch loop subjected to the split stitch, this method of ravel stopping is shown by way of example and other methods than this are possible.
- the stitch loop subjected to the split stitch may be removed.
- Simply removing the stitch loop subjected to the split stitch eventually forms a stitch loop that is similar to one of a knit and is able to be used in the case where the position of the yarn feeding position is heightened due to yarn feeding, floating stitch, and the like.
- subsequent to the yarn feeding in the same knitting course, it is possible to form a stitch loop on a knitting needle different from the knitting needle used for the split stitch and then remove the stitch loop subjected to the split stitch.
- the stitch loop is temporarily transferred to carry out a split stitch and a stitch loop newly formed by the split stitch is removed, then eventually this returns to the state before the stitch transfer.
- the stitch loop at the edge portion of the pattern area of A is transferred to carry out a split stitch, and after forming a stitch loop in the pattern area of B in the knitting course that is the same as or subsequent to the knitting course where the increment was carried out, the stitch loop newly formed by split stitch at the edge portion of the pattern area of A is removed, then the stitch loop in the pattern area of A returns to the state before the stitch transfer, thereby securing yarn feeding for knitting of the pattern area of B.
- the pattern areas of A and B are knitted by repeating a required number of courses while hauling the yarn carriers 6a and 6b by systems S1 and S2.
- the stitch loop transferred in the course 13 is subjected to a split stitch to the knitting needle 3 side of the front needle bed 1. This can surely capture a cross-over yarn generated by yarn feeding from the edge portion 29 of the pattern area of B in the vicinity of the selvedge of the fabric 9 and prevent floating at the needle bed gap 5.
- the yarn carrier 6b is returned to a position that is closer to the side of the pattern area of B than the positions of the knitting needles 3 and 4 where the split stitch was carried out.
- the stitch loop that is a former loop relative to the newly formed stitch loop is the stitch loop transferred in the course 13, and part of this stitch loop is engaged in the front needle bed 1 side by the split stitch in the course 15, and therefore, this stitch loop is absorbed in the stitch loop of the knitting needle 3 of the front needle bed 1, and as a result, the stitch transfer in the course 13 returns to the original in the course 17.
- Fig. 11 shows effects of forming the crossing portion in the course 1 of Fig. 8 .
- Fig. 11(a) shows a state in which the carriage 31 hauls the yarn carrier 6a leftward in the course 1.
- the yarn carrier 6b which feeds the knitting yarn 6b, waits outside the knitting width of the fabric 9.
- the knitting yarn 7b is the cross-over yarn from the yarn feeding port at the distal end of the yarn carrier 6b.
- Fig. 11(b) shows a state in which the carriage hauls the yarn carrier 6b rightward in the course 2 after a crossing portion is formed by a stitch transfer in the course 1 of Fig. 8 .
- the knitting yarn 7b that is to be a cross-over yarn is fed to knit the edge portion 28 of Fig. 6 with the crossing portion serving as a starting point 40.
- the cross-over yarn is directly fed from the edge portion of the pattern area of B knitted in advance at the time of knitting of the edge portion 28.
- the position of the pattern area of B knitted in advance can vary in various ways as the fabric 9 requires, such as 9b 1 and 9bs etc., and therefore the knitting conditions of the edge portion 28 to which yarn feeding is carried out change accordingly.
- Providing the starting point 40 stabilizes the positional relation of a cross-over yarn 7b0 from the starting point 40 to the edge portion 28 even when the positions of cross-over yarns 7b1 and 7b2 vary from pattern areas 9b1 and 9b2 to the starting point 40, thereby making it possible to make the constant knitting conditions uniform.
- Fig. 12 and Fig. 13 show a schematic procedure of a concept to capture the cross-over yarn by a split stitch as described above and a schematic structure of a design device that creates knitting data including the schematic procedure.
- pattern data is input in step s1.
- step s2 whether there is any section in which the knitting yarn 7 becomes a cross-over yarn is judged.
- the cross-over yarn is captured by a split stitch in step s3.
- regular knitting such as a knit is carried out.
- a design device 50 is embodied by installing software that designs fabrics to a general-purpose computer 51.
- the installation may be carried out by downloading through a communication device 54 or by mounting a recording medium to an external memory device 55.
- This software includes a program to create knitting data that captures a cross-over yarn with the use of a split stitch in the procedure shown in Fig. 12 .
- an input device 52 such as a keyboard, digitizer, mouse, a display device 53 such as a graphic display, a communication device 54 capable of external communication through the LAN and the like, an external memory device 55 to which various recording media are able to be attached and detached, and the like are connected.
- An operator inputs design data to the input device 52 and designs the fabric 9 while watching the design results displayed on the display device 53.
- the operator instructs for a split stitch.
- the computer 51 adds knitting data of the split stitch.
- the knitting data in which the split stitch is added is transmitted to the flat knitting machine 30 through the communication device 54 or input to the flat knitting machine 30 after being recorded in a recording medium such as a disk and USB memory from the external memory device 55 so as to knit the fabric 9.

- The present invention relates to a method for knitting a fabric and a design device to, in intarsia patterns, floating stitches, and the like, capture a knitting yarn in the hook of a knitting needle when the knitting yarn is let loose to avoid engagement in the knitting needle and be fed as a cross-over yarn.
- Conventionally, a flat knitting machine is used to knit fabrics including an intarsia pattern and the like by changing over a plurality of knitting yarns in the same knitting course (for example, see Patent Citation 1).
- Knitting yarns used for knitting fabrics on flat knitting machines are fed to knitting needles from a yarn feeding member such as a yarn carrier, which moves along a needle bed gap in cooperation with the fabric knitting operation of the knitting needles. The intarsia pattern and the like to be knitted are in the form of being fitted in the fabric serving as a ground. Consequently, at the start portion and the end portion of the intarsia pattern and the like, yarn in and yarn out of a knitting yarn different from the ground fabric are carried out.
- When the fed in knitting yarn is provided with a long distance for a cross-over yarn, which is let loose to avoid engagement in the knitting needle, the position of yarn feeding from a yarn carrier and the like floats from the needle bed gap at the end part where knitting of an intarsia pattern and the like starts, thereby making it difficult to capture the fed knitting yarn in the hook of the knitting needle. In addition, in a crossing section where the yarn becomes a cross-over yarn after yarn out, the cross-over yarn might be erroneously captured in a knitting needle that is knitting the fabric and thus be knitted into the fabric or might be entangled to the detriment of the knitting operation. The problem of floating of the cross-over yarn from the needle bed gap and difficulty in capturing in the knitting needle occurs not only in the intarsia-pattern knitting but also in fabrics of the floating stitch. In order to prevent the cross-over yarn from floating between the needle bed gap in the cross-over section and to secure that the knitting needle captures the cross-over yarn at the end of a knitting section where the cross-over yarn is used as a knitting yarn, such processing is carried out as knitting the cross-over yarn into the fabric such as by a tuck in the cross-over section, thus preventing the cross-over yarn from floating from the needle bed gap. However, knitting the cross-over yarn into the fabric by a tuck and the like requires the work of removing the knitted cross-over yarn portion in the subsequent process.
- Also proposed are a yarn processing method and a knitting method that temporarily capture the knitting yarn to be a cross-over yarn with the use of knitting needles in the cross-over section and release the captured cross-over yarn after knitting of a plurality of courses (see, for example,
Patent Citations 2 and 3). However, as the interval between the capturing knitting needles increases, the cross-over yarn floats from the needle bed gap. Therefore, when the cross-over section is elongated, the number of capturing knitting needles must be increased. Also disclosed is a method for capturing the cross-over yarn such that instead of engaging the cross-over yarn in the hook of the knitting needle, the knitting needle is guided to the lower side of the hook and held (see, for example, Patent Citation 4). The requisite of this method is that the movements of the knitting needle and yarn feeding member are individually controllable, which necessitates mounting of a new cam mechanism in the flat knitting machines, by which fabrics are knitted while moving a carriage mounting therein a cam mechanism along the needle bed gap with the accompaniment of the yarn carrier. - Patent Citation 1: Japanese Examined Patent Application Publication No.

H09-31804 - It is an object of the present invention to provide a method for knitting a fabric and a design device which can surely capture a knitting yarn which is floating from a needle bed gap and difficult to capture in the hook of a knitting needle.
- The present invention provides a method for knitting a fabric on a flat knitting machine provided with at least a pair of front and rear needle beds opposed to one another across a needle bed gap, each of the needle beds being provided with a multiplicity of latch needles as knitting needles, which comprises:
- carrying out a split knit of a stitch loop held in the knitting needle of the one needle bed into a knitting needle of the other needle bed; and
- capturing a knitting yarn as a newly formed knitting loop in a hook of a knitting needle of the one needle bed, the knitting yarn serving as a cross-over yarn by being let loose over a distance so as to avoid engagement of the knitting yarn in knitting needles, the distance makes it difficult to capture the knitting yarn in a hook of a knitting needle which independently carrying out a stitch forming operation.
- According to the present invention,
prior to the split knit, the held stitch loop is transferred to the knitting needle of the one needle bed from a fabric belonging to the other needle bed; and
after the split knit, the newly formed stitch loop is removed from the knitting needle of the one needle bed. - According to the present invention,
the knitting yarn is used for knitting an inner area of the fabric and becomes the cross-over yarn during yarn out;
the split knit is carried out in the vicinity of an end portion of the fabric; and
after the split knit, the newly formed stitch loop is removed from the knitting needle of the other needle bed after knitting of a predetermined number of courses. - According to the present invention,
the stitch loop newly formed by the split stitch is removed from the knitting needle of the one needle bed after, subsequent to the split stitch, a stitch is formed on a knitting needle different from the knitting needle used for the split stitch. - According to the present invention,
the stitch loop subjected to the split stitch into the knitting needle of the other needle bed, or a stitch loop knitted following the split stitch loop is transferred to the one needle bed side to stop ravel. - According to the present invention,
the knitting yarn is fed in such a manner that the knitting yarn becomes the cross-over yarn from a portion kitted before the plurality of courses of the fabric;
in a knitting course where the split knit is carried out, a portion where the knitting yarn crosses between the needle beds is formed in the vicinity of the end portion of the fabric; and
the crossing portion is released after the cross-over yarn is fed in and captured in the knitting needle carrying out the split knit through the crossing portion. - Furthermore, the present invention provides a design device of a fabric for creating knitting data to knit a fabric on a flat knitting machine, the flat knitting machine being provided with at least a pair of front and rear needle beds opposed to one another across a needle bed gap, each of the needle beds being provided with a multiplicity of latch needles as knitting needles, the knitting data created by the design device causing the flat knitting machine to execute a method which comprises;
carrying out a split knit of a stitch loop held in the knitting needle of the one needle bed into a knitting needle of the other needle bed; and
capturing a knitting yarn as a newly formed knitting loop in a hook of a knitting needle of the one needle bed, the knitting yarn serving as a cross-over yarn by being let loose over a distance so as to avoid engagement of the knitting yarn in knitting needles, the distance makes it difficult to capture the knitting yarn in a hook of a knitting needle which independently carrying out a stitch forming operation. - According to the present invention, a multiplicity of latch needles are disposed on a pair of front and rear needle beds as knitting needles, and even the knitting yarn in the cross-over yarn state floating from the needle bed gap is guided inside the hook when a split stitch between the needle beds causes the stitch loop subjected to the split into an opposite needle bed to close the latch in the needle bed gap, thereby making it possible to surely capture the knitting yarn. Thus, the knitting yarn is definitely captured and knit a stable fabric.
- In addition, according to the present invention, the stitch loop subjected to the split stitch is one that is transferred in advance from the needle bed to which the fabric belongs to the opposite needle bed, which makes it possible to return the transferred stitch loop to the original needle bed side as the split stitch. After the split stitch, the new stitch loop is removed from the knitting needle to which the transfer was carried out, thereby eliminating the need for processing of the stitch loop newly formed by the split stitch in a subsequent process.
- In addition, according to the present invention, even in the case where the distance of the cross-over yarn is long when the yarn is out, the cross-over yarn is surely captured in the hook of the knitting needle in the vicinity of the end portion of the fabric, and in predetermined course knitting, the cross-over yarn is able to be held to prevent it from floating between the needle bed gap.
- In addition, according to the present invention, the stitch loop newly formed by the split stitch is removed after a stitch loop following the split stitch is formed on a knitting needle different from the knitting needle of the stitch loop that was used for the split stitch. This makes it possible to surely capture the knitting yarn with the use of the split stitch at the time of yarn feeding, and to return the stitch loop to the fabric before transfer, whereby the stitch loop can be rendered equivalent to a stitch loop formed by a single knitting.
- In addition, according to the present invention, the stitch loop follows the split stitch can be returned to the split starting side by transfer instead of being removed so as to be utilized effectively to prevent a ravel.
- In addition, according to the present invention, the state in which the knitting yarn fed in a state of a cross-over yarn, which avoids engagement in the knitting needle, floats from the needle bed gap varies depending on differences in the position of a portion of the knitting yarn where the preceding knitting course finished. Before the knitting course in which the cross-over yarn is reused, a portion where the knitting yarn crosses the needle beds is formed, and therefore, the cross-over yarn is fed to the knitting needle that carries out the split stitch through the crossing portion. By forming the crossing portion in the vicinity of the end portion of the fabric, the crossing portion is rendered a starting point of yarn feeding to have a uniform condition for capturing the knitting yarn in the hook of the knitting needle, thereby making it possible to ensure the capture.
- Furthermore, according to the present invention, knitting data can be created in such a manner that when a knitting yarn not engaged in the knitting needle becomes a cross-over yarn by floating from the needle bed gap, such knitting yarn can be surely captured in the hook of the knitting needle by split stitch.

Fig. 1 is one embodiment of the present invention showing a state in which a knitting yarn is captured in the hook of a knitting needle with the use of a knitting operation of split stitch. In a flat knitting machine provided with afront needle bed 1 and arear needle bed 2, in order to execute a split stitch method as disclosed in, for example, Japanese Examined Patent Application Publication No.S62-52063 knitting needles front needle bed 1 and therear needle bed 2 are opposed to one another across aneedle bed gap 5, and able to advance and retire the tip sides of theknitting needles needle bed gap 5. Theknitting needles knitting needles needle bed gap 5, theknitting needle 3 at its midpoint is provided with a clip 3c. Above theneedle bed gap 5, ayarn carrier 6 is movably provided in a direction perpendicular to the paper surface and feedsknitting yarn 7 through a yarn feeding port at the distal end. When theknitting yarn 7 is fed to the hooks 3a and 4a of theknitting needles needle bed gap 5, astitch loop 8 is formed by the knitting operation of theknitting needles stitch loop 8 parts from theknitting needles fabric 9 and hangs below theneedle bed gap 5 by dead weight and various kinds of biasing. In an split stitch with thestitch loop 8 formed on theknitting needle 3 of thefront needle bed 1, when thestitch loop 8 is transferred to theknitting needle 4 of therear needle bed 2, a new stitch loop is also formed on the hook 3a of theknitting needle 3 from aknitting yarn 7 fed from theyarn carrier 6. -
Fig. 1(a) shows a state in which after thestitch loop 8 is held at the clip 3c portion of theknitting needle 3 of thefront needle bed 1 and is allowed to advance to theneedle bed gap 5, the hook 4a of theknitting needle 4 of therear needle bed 2 is allowed to go into the clip 3c portion and thestitch loop 8 is engaged in the hook 4a. When theknitting needle 3 is pulled to thefront needle bed 1 side, thestitch loop 8 parts from the clip 3c and comes close to the tip of the latch 3b in an open state, since thestitch loop 8 is engaged in the hook 4a of theknitting needle 4 of therear needle bed 2. As shown inFig. 1(b) , when theknitting needle 3 is further pulled to thefront needle bed 1 side, thestitch loop 8 remaining on theknitting needle 3 raises and displaces the hook 3b in such a manner as to close the hook 3a. Although the position of theyarn carrier 6 relative to theknitting needles knitting yarn 7 hanging from the tip of the yarn feeding port extends in the direction perpendicular to the paper surface, and passes through the latch 3b open/close range. As shown inFig. 1(c) , when the latch 3b closes the hook 3a while thestitch loop 8 is passing, theknitting yarn 7 fed through the yarn feeding port of theyarn carrier 6 can be captured in the hook 3a. When theknitting needle 3 is further pulled to thefront needle bed 1 side, the portion of thestitch loop 8 engaged in theknitting needle 3 comes around the tip of theknitting needle 3 along the circumferential portion of the latch 3b that is closing the hook 3a, thus parting from theknitting needle 3. Theparting stitch loop 8 is engaged only in the hook 4a at the tip of theknitting needle 4 to end up as a stitch loop on therear needle bed 2 side while being a knocked-over former loop for the stitch loop newly formed on theknitting needle 3. -
Fig. 2 shows one example of acam system 10 that carries out the knitting operation to theknitting needle 3 of thefront needle bed 1, which carries out transfer by the split stitch operation shown inFig. 1 . As described later, this cam system is one of a plurality of sets mounted to the carriage along theneedle bed gap 5, and is shown with the needle bed gap side upward. Hereinafter, when reference is made to "up" and "down" relative to the needle bed gap, a portion closer to the needle bed gap may be indicated as "upper" and a portion away from the needle bed gap may be indicated as "lower". - A
ground board 11 of the carriage facing the needle bed is provided with a stitch forming cam rock 15 including aneedle raising cam 12 andstitch cams cam rock 18 including a stitch receivingtransfer cam 16 and atransfer cam 17 for both transfer and reception. Thestitch cams needle raising cam 12 has a lower fixedportion 19 and an uppermovable portion 20. Themovable portion 20, provided with a mechanism not shown, protrudes and recedes with respect to theground board 11 alternately with thetransfer cam 17 for both transfer and reception in such a manner that when one protrudes, the other recedes. Themovable portion 20 is provided with a butt guiding groove 20a. The butt guiding groove 20a is bent in a mountainous form with its center portion approaching the needle bed gap side, and links to the slope of the fixedportion 19 through a horizontal shoulder portion 20b on both sides of the groove. - The fixed
portion 19 on its upper center portion is provided with the stitch receivingtransfer cam 16 in a freely protruding/receding manner. The stitch receivingtransfer cam 16 is symmetrical, both sides of which are inclined in such a manner that a portion closer to the center becomes deeper. - The
transfer cam 17 for both transfer and reception above theneedle raising cam 12 is roughly in the form of mountainous triangles with two peaks disposed side by side. On the upper edge side, thetransfer cam 17 guides a knitting needle butt on the stitch transferring side, and on the lower edge side, guides a knitting needle butt on the stitch receiving side. Above thetransfer cam 17 for both transfer and reception, atransfer guide cam 21 is provided, on both sides of which continueneedle guide cams 22. - When the
knitting needle 3 on the stitch transferring side is driven, themovable portion 20 of theneedle raising cam 12 is kept in the receding state as indicated by a chain double-dashed line while thetransfer cam 17 for both transfer and reception is kept in the protruding state as indicated by a solid line. Theknitting needles cam system 10, with anupper butt 23 being acted upon by the stitch transferringcam rock 18 and alower butt 24 being acted upon by the stitch forming cam rock 15. Assuming that the carriage provided with thecam system 10 runs leftward in the figure, theupper butt 23 and thelower butt 24 of theknitting needle 3 on the stitch transferring side move along the courses indicated by chain double-dashed lines. The positions of theupper butt 23 and thelower butt 24 corresponding toFig. 1(a), 1(b), and 1(c) are respectively indicated by 23a, 23b, and 23c; 24a, 24b, and 24c. In addition, the position shown as theyarn carrier 6 is represented by the position at which theknitting yarn 7 from the yarn feeding port of theyarn carrier 6 is received in the hook 3a of theknitting needle 3. -
Fig. 3 shows a state in which theknitting needle 4 of therear needle bed 2 is made to perform a knitting operation for a stitch receiving side by the split stitch operation shown inFig. 1 with the use of thecam system 10 ofFig. 2 . As opposed to thecam system 10 ofFig. 1 being mounted to the carriage of thefront needle bed 1, thecam system 10 ofFig. 3 is mounted to the carriage of therear needle bed 2. Therefore, for convenience of explanation,Fig. 3 is shown to be symmetrical toFig. 2 with the needle bed gap side down. Corresponding portions inFigs. 2 and3 are denoted by the same numerals and overlapping explanations will be omitted inFig. 3 . However, when theknitting needle 4 on the stitch receiving side is driven, themovable portion 20 of theneedle raising cam 12 is kept in the receding state as indicated by a chain double-dash line while thetransfer cam 17 for both transfer and reception is kept in the protruding state as indicated by a solid line. - In addition, the
knitting needle 4 is also acted upon bypressers Fig. 2 . Thecam system 10 selects the position of theknitting needle 4 among three positions to be acted upon by one of thepressers Fig. 1 of Japanese Examined Patent Application Publication No.H02-10262 knitting needles Fig. 2 of Japanese Examined Patent Application Publication No.H02-10262 - The
pressers knitting needle 4 is operated as the stitch receiving side, theintermediate presser 27 is switched out of action as indicated by a chain double-dashed line. When thepressers 25 and 26 are made to act upon theknitting needle 4, thelower butt 24 of theknitting needle 4 is no longer acted upon by the fixedportion 19 but is acted upon by the stitch receivingtransfer cam 17 at the center to advance to the needle bed gap side. When theknitting needle 4 advances, theupper butt 23 comes in contact with the lower edge of thetransfer cam 17 for both transfer and reception and descends along the guide surface formed on the lower edge. When thelower butt 24 comes in contact with the sloping cam surface 13a of thestitch cam 13, thelower butt 24 is guided in such a manner to descend along the cam surface 13a. The positions of theupper butt 23 and thelower butt 24 corresponding toFig. 1(a), 1(b), and 1(c) are respectively indicated by 23a, 23b, and 23c; 24a, 24b, and 24c. -
Fig. 4 shows a state in which theknitting needle 3 is made to perform a knitting operation of a knit with the use of thecam system 10 ofFig. 2 . In the knit, the tip of theknitting needle 3 is temporarily advanced to theneedle bed gap 5 to a clear position where thestitch loop 8 retracts behind the latch 3b. Thestitch loop 8 that continues into thefabric 9 stays in the vicinity of the tip of thefront needle bed 1, since thefabric 9 is biased below theneedle bed gap 5.Fig. 4(a) shows a state in which theknitting needle 3 that was allowed to advance into theneedle bed gap 5 to the clear position is pulled back to thefront needle bed 1 and is fed aknitting yarn 7 from theyarn carrier 6. As shown inFig. 4(b) , when theknitting needle 3 is pulled to thefront needle bed 1 to retract from theneedle bed gap 5, thestitch loop 8 starts to close the latch 3b. As shown inFig. 4(c) , when the position of theknitting yarn 7 pending from the yarn feeding port at the distal end of theyarn carrier 6 is high before the latch 3b closes the hook 3a and thestitch loop 8 parts from the tip of theknitting needle 3, then theknitting yarn 7 cannot be captured in the hook 3a for yarn catching. As described in thePatent Citation 4 in relation to itsFig. 2 , after a long non-knitting section, the height of theknitting yarn 7 increases to make it difficult to carry out yarn catching by the knitting operation of a knit. -
Fig. 5 shows a switching state of thecam system 10 when the knitting operation of a knit as shown inFig. 4 is performed. When theknitting needle 3 is driven in the knitting operation of a knit, themovable portion 20 of theneedle raising cam 12 is kept in the protruding state as indicated by a solid line while thetransfer cam 17 for both transfer and reception is kept in the receding state as indicated by a chain double-dashed line. It should be noted that even when theknitting needle 3 is made to carry out the knitting operation for stitch transfer in the state ofFig. 2 , theknitting needle 3 will form a stitch loop similar to a knit unless theopposite knitting needle 4 is made to carry out the knitting operation for stitch reception in the state ofFig. 3 . The positions of theupper butt 23 and thelower butt 24 corresponding toFig. 4(a), 4(b), and 4(c) are respectively indicated by 23a, 23b, and 23c; 24a, 24b, and 24c. In addition, the position shown as theyarn carrier 6 is represented by the position at which theknitting yarn 7 from the yarn feeding port of theyarn carrier 6 is received in the hook 3a of theknitting needle 3. -
Fig. 6 shows a simplified diagram of an example of thefabric 9. In each course, in an X section in the wale direction, a pattern area 9xa of A is knitted, and in a Y section in the wale direction, a pattern area 9yb of B is knitted in a pattern area 9ya of A. In addition, in a Z section in the wale direction, only a pattern area 9za of A is knitted. Insuch fabric 9, processing of cross-over yarn is required at the time of yarn feeding at anedge portion 28 of the pattern area 9yb and at the time of yarn retrieval from anedge portion 29. -
Fig. 7 schematically shows a structure of aflat knitting machine 30 that knits thefabric 9. Thefront needle bed 1 is provided with acarriage 31 mounted with a cam system capable of knitting, transfer, split stitch, and the like. Thecarriage 31 selectively takes yarn carriers 6a and 6b that can travel along ayarn guide rail 32 provided above the needle gap, and travels reciprocatedly in the longitudinal direction of the needle bed. It is assumed that the pattern area of A ofFig. 6 is knitted with a knitting yarn 7a fed from the yarn carrier 6a and the pattern area of B is knitted with a knitting yarn 7b fed from the yarn carrier 6b. In theflat knitting machine 30, the knitting yarns 7a and 7b are fed from cones 33a and 33b disposed upright on acone stand plate 33 to the yarn carriers 6a and 6b, respectively, at a substantially constant tension through ayarn tension device 34 and ayarn feeding device 35. When knitting of thefabric 9 starts, the end of the knitting yarn is grasped by agripper 36 provided at the end portion of the needle bed. In knitting of thefabric 9 ofFig. 6 , even when knitting of the X section in the wale direction starts, the end portion of the knitting yarn 7b is grasped by thegripper 36 until knitting of theedge portion 28 of the pattern area 9yb of the Y section starts. Therefore, when knitting of theedge portion 28 starts, theknitting yarn 7 fed from the yarn carrier 6b is at a high position floating from theneedle gap 5. Consequently, although in the knitting operation of a knit as shown inFig. 4 it becomes difficult to capture theknitting yarn 7 in the hook 3a, paying attention to and utilizing the split stitch operation as shown inFig. 1 can capture theknitting yarn 7 at a high position more surely in the hook 3a. - Incidentally, the need for capturing the
knitting yarn 7 at a high position in the hook 3a occurs not only in knitting of intarsia patterns but also in floating stitches, where knitting is carried out after misses to the knitting needle are continued, and in the case where knitting of an area of an independent fabric such as a pocket newly starts in a fabric. Also in these cases, utilizing the split stitch can capture theknitting yarn 7 surely in the hook 3a. -
Figs. 8 ,9 , and10 each show a state in which knitting of the X section in the wale direction is finished and knitting of the Y and Z sections for thefabric 9 ofFig. 6 is carried out. The numbers shown under "course" on the left side of each figure indicate relative course numbers. In the odd-number courses, the carriage runs leftward while in the even-number courses the carriage runs rightward. The symbols shown under "system" on the right side of each figure each show whichcam system 10 is used when eachcarriage 31 mounts thereon threecam systems 10 such as those shown inFigs. 2 ,3 , and5 . Specifically, S1 indicates a system on the preceding side, S2 indicates an intermediate system, and S3 indicates a system on the following side. Consequently, when the carriage runs leftward, thecam system 10 on the left side is designated as S1 and thecam system 10 on the right side is designated as S3 while when the carriage runs rightward, thecam system 10 on the right side is designated as S1 and thecam system 10 on the left side is designated as S3. It should be noted that the use of the cam system is shown by way of example. In addition, as shown inFig. 9 , since thecourse 7 and thecourse 8 are repeated in a plurality of times, the numerical characters on and after thecourse 9 do not mean the courses on and after the 9th course relative to thecourse 1. - In the
course 1, using the yarn carrier 6a indicated as "a" and the system S1, the last course knitting in the X section in the wale direction is carried out by the knitting yarn 7a at thefront needle bed 1. Simultaneously, using the system S2, a stitch transfer is carried out from thefront needle bed 1 to therear needle bed 2 in the pattern area of A. This stitch transfer is for the purpose of forming a crossing portion in theneedle bed gap 5 using the knitting yarn 7a. The position where the crossing portion is formed is preferably in the vicinity of the edge portion of the knitting width of thefabric 9. There is no need to form a new crossing portion in the case where a crossing portion is formed by a rib stitch and the like in the pattern area of A, or in the case where thefabric 9 is knitted in the form of a bag and a knitting yarn that communicates thefront needle bed 1 and therear needle bed 2 with one another exists at the edge portion. - From the
course 2, the first course knitting of the Y section in the wale direction starts. The yarn carrier 6b that feeds the knitting yarn 7b stands by on the left side of thefront needle bed 1 as shown inFig. 7 . However, in the case where the X section in the wale direction is already knitted and the pattern area of B is knitted in the X section, the knitting yarn 7b links not to thegripper 36 but to the edge portion of the knitted pattern area of B, from the yarn feeding port at the distal end of the yarn carrier 6b. In this state, when, using the system S3, the yarn carrier 6b indicated as "b" is took rightward, the knitting yarn 7b is fed to theedge portion 28 ofFig. 6 after being engaged in the crossing portion formed in thecourse 1. At theedge portion 28, split stitch is carried out. As described above, since the split stitch is used, even when the position of the knitting yarn 7b fed from the yarn carrier 6b is high, the knitting yarn 7b can be surely captured in the hook 3a of theknitting needle 3. - In the case where the configuration and specification of the
yarn carrier 6 and thecam system 10 differ, it might be difficult to carry out an split stitch while taking the yarn carrier 6b by thecarriage 31. In this case, by the rightward run of thecarriage 31, the yarn carrier 6b is moved in advance inside the pattern area 9yb of B and stopped. Although the position of the knitting yarn 7b fed from the yarn carrier 6b at theedge portion 28 of the pattern area 9yb is heightened, it is possible to use separate knitting courses such that the yarn carrier 6b is left and thecarriage 31 is moved leftward in an empty course, and then, thecarriage 31 runs rightward so as to capture the knitting yarn 7b in the hook 3a by split stitch. - In the
course 3, where the yarn carrier 6b runs leftward and the system S1 is used, formation of a stitch that follows the stitch loop subjected to the split stitch at theknitting needle 4 of therear needle bed 2 is carried out at theedge portion 28, where the split stitch was carried out in thecourse 2, and hooking to theknitting needle 4 of the adjacent pattern area 9ya of A is carried out. The stitch loops subjected to the split stitch in thecourse 2 into theknitting needle 4 of therear needle bed 2 becomes a former loop by knocking-over. - In the
course 4, the yarn carrier 6b runsa rightward by the system S1, and hooking to therear needle bed 2 is transferred to thefront needle bed 1 by the system S2. By effecting a tension to the knitting yarn 7b in the opposite direction by the system S1 and carrying out a stitch transfer by the system S2 relative to the hooking, a twisted stitch can be formed at the edge portion of the pattern area side of A of thefront needle bed 1. - In the
course 5, the yarn carrier 6b is advanced to the pattern area side of A by the system S1, and furthermore, a stitch transfer is carried out such that the stitch transferred to theknitting needle 4 of therear needle bed 2 in thecourse 1 is returned to theknitting needle 3 of thefront needle bed 1. When an split stitch is carried out to form a crossing portion, the stitch loop formed on theknitting needle 4 of therear needle bed 2 is removed and released. This crossing portion functioned as the starting point of yarn feeding and is no longer necessary after completion of thecourse 2. - In the
course 6, subsequent to the hooking to the edge portion of the adjacent pattern area of A, the course knitting of the pattern area of B is carried out by hauling the yarn carrier 6b by the system S1. In addition, knitting of the pattern area of A is carried out by hauling the yarn carrier 6a by the system S2. Furthermore, with the use of the system S3, the stitch loop that was subjected to the split stitch in thecourse 2 and is held in theknitting needle 4 of therear needle bed 2 at theedge portion 28 of the pattern area of B is transferred to theknitting needle 3 of thefront needle bed 1. - In the yarn processing from the
course 2 to thecourse 6, ravel stopping can be carried out for theedge portion 28. Although this ravel stopping is carried out with the use of the stitch loop subjected to the split stitch, this method of ravel stopping is shown by way of example and other methods than this are possible. - When no ravel stopping is performed, the stitch loop subjected to the split stitch may be removed. Simply removing the stitch loop subjected to the split stitch eventually forms a stitch loop that is similar to one of a knit and is able to be used in the case where the position of the yarn feeding position is heightened due to yarn feeding, floating stitch, and the like. In addition, subsequent to the yarn feeding, in the same knitting course, it is possible to form a stitch loop on a knitting needle different from the knitting needle used for the split stitch and then remove the stitch loop subjected to the split stitch.
- Furthermore, when the stitch loop is temporarily transferred to carry out a split stitch and a stitch loop newly formed by the split stitch is removed, then eventually this returns to the state before the stitch transfer. For example, at the time of yarn feeding to start knitting of the pattern area of B, when the stitch loop at the edge portion of the pattern area of A is transferred to carry out a split stitch, and after forming a stitch loop in the pattern area of B in the knitting course that is the same as or subsequent to the knitting course where the increment was carried out, the stitch loop newly formed by split stitch at the edge portion of the pattern area of A is removed, then the stitch loop in the pattern area of A returns to the state before the stitch transfer, thereby securing yarn feeding for knitting of the pattern area of B.
- In the
course 7 and thecourse 8, the pattern areas of A and B are knitted by repeating a required number of courses while hauling the yarn carriers 6a and 6b by systems S1 and S2. - In the
course 9, where the carriage is moved leftward, the last course knitting is carried out by switching between the pattern area of A and the pattern area of B in the same course. Lastly, by the system S3, a stitch loop of theedge portion 29 of the pattern area of B is transferred from theknitting needle 3 of thefront needle bed 1 to theknitting needle 4 of therear needle bed 2. - In the
course 10, by the system S1, the yarn carrier 6b is hauled and returned to the pattern area of B. - In the
course 11, while hauling the yarn carrier 6b to the side of the pattern area of A by the system S1, in the pattern area of B, hooking is carried out from theedge portion 29 to theknitting needle 3 of the secondfront needle bed 1, and stitch formation in theknitting needle 4 of therear needle bed 2 of theedge portion 29 is carried out. - In the
course 12, by the system S1, the stitch loop formed in theknitting needle 4 of therear needle bed 2 at theend 29 of the pattern area of B is transferred to theknitting needle 3 of thefront needle bed 1. In the yarn processing from thecourse 9 to thecourse 12, ravel stopping can be carried out for theedge portion 29 where yarn retrieval is carried out. This method of ravel stopping is shown by way of example and other methods than this are of course possible. - In the
course 13, using the system S1, a stitch is transferred from theknitting needle 3 of thefront needle bed 1 to theknitting needle 4 of therear needle bed 2 in the vicinity of the edge portion of the knitting width inside the pattern area of A. - In the
course 14, the yarn carrier 6b is returned to the pattern area of B. - In the course 15, while moving the yarn carrier 6b outside the knitting width of the
fabric 9 so that the yarn carrier 6b is further away from the position of the pattern area of B than the stitch transferred in thecourse 13, the stitch loop transferred in thecourse 13 is subjected to a split stitch to theknitting needle 3 side of thefront needle bed 1. This can surely capture a cross-over yarn generated by yarn feeding from theedge portion 29 of the pattern area of B in the vicinity of the selvedge of thefabric 9 and prevent floating at theneedle bed gap 5. - In the
course 16, the yarn carrier 6b is returned to a position that is closer to the side of the pattern area of B than the positions of theknitting needles - In the
course 17, where the yarn carrier 6b is hauled by the system S1, hooking to outside the knitting width of thefabric 9 is carried out. Since by the split stitch of the course 15 the cross-over yarn is surely captured in theknitting needle 4, the hooking can also be carried out surely. By the system S2, the stitch loop newly formed by the split stitch in the course 15 is removed from theknitting needle 14 of therear needle bed 2. The removed stitch loop is absorbed as a knitting yarn for yarn retrieval that is to be hooked outside thefabric 9. In addition, the stitch loop that is a former loop relative to the newly formed stitch loop is the stitch loop transferred in thecourse 13, and part of this stitch loop is engaged in thefront needle bed 1 side by the split stitch in the course 15, and therefore, this stitch loop is absorbed in the stitch loop of theknitting needle 3 of thefront needle bed 1, and as a result, the stitch transfer in thecourse 13 returns to the original in thecourse 17. - In the
courses course 20 is removed at last, the cross-over yarn for yarn retrieval is pulled down from theneedle bed gap 5 together with thefabric 9 and the cross-over yarn no longer floats from theneedle bed gap 5. - It is noted that when, after the split stitch is carried out in the course 15, knitting is carried out by a required number of courses and then the stitch loop is removed from the
knitting needle 4 of therear needle bed 2, then the hooking in thecourse 17 and the removal in thecourse 20 need not be carried out. -
Fig. 11 shows effects of forming the crossing portion in thecourse 1 ofFig. 8 .Fig. 11(a) shows a state in which thecarriage 31 hauls the yarn carrier 6a leftward in thecourse 1. The yarn carrier 6b, which feeds the knitting yarn 6b, waits outside the knitting width of thefabric 9. In the case where the pattern area of B is knitted prior to thefabric 9, the knitting yarn 7b is the cross-over yarn from the yarn feeding port at the distal end of the yarn carrier 6b. -
Fig. 11(b) shows a state in which the carriage hauls the yarn carrier 6b rightward in thecourse 2 after a crossing portion is formed by a stitch transfer in thecourse 1 ofFig. 8 . The knitting yarn 7b that is to be a cross-over yarn is fed to knit theedge portion 28 ofFig. 6 with the crossing portion serving as astarting point 40. In the case where nostarting point 40 is provided, the cross-over yarn is directly fed from the edge portion of the pattern area of B knitted in advance at the time of knitting of theedge portion 28. The position of the pattern area of B knitted in advance can vary in various ways as thefabric 9 requires, such as9b 1 and 9bs etc., and therefore the knitting conditions of theedge portion 28 to which yarn feeding is carried out change accordingly. Providing thestarting point 40 stabilizes the positional relation of a cross-over yarn 7b0 from thestarting point 40 to theedge portion 28 even when the positions of cross-over yarns 7b1 and 7b2 vary from pattern areas 9b1 and 9b2 to thestarting point 40, thereby making it possible to make the constant knitting conditions uniform. -
Fig. 12 and Fig. 13 show a schematic procedure of a concept to capture the cross-over yarn by a split stitch as described above and a schematic structure of a design device that creates knitting data including the schematic procedure. As shown inFig. 12 , when thefabric 9 shown inFig. 6 is knitted on theflat knitting machine 30 shown inFig. 7 , pattern data is input in step s1. In step s2, whether there is any section in which theknitting yarn 7 becomes a cross-over yarn is judged. When it is judged that there is a cross-over yarn, the cross-over yarn is captured by a split stitch in step s3. When it is not judged that there is a cross-over yarn in step s2, regular knitting such as a knit is carried out. - As shown in
Fig. 13 , adesign device 50 is embodied by installing software that designs fabrics to a general-purpose computer 51. The installation may be carried out by downloading through acommunication device 54 or by mounting a recording medium to an external memory device 55. This software includes a program to create knitting data that captures a cross-over yarn with the use of a split stitch in the procedure shown inFig. 12 . To the computer 51, aninput device 52 such as a keyboard, digitizer, mouse, a display device 53 such as a graphic display, acommunication device 54 capable of external communication through the LAN and the like, an external memory device 55 to which various recording media are able to be attached and detached, and the like are connected. An operator inputs design data to theinput device 52 and designs thefabric 9 while watching the design results displayed on the display device 53. When the section to be a cross-over yarn becomes long and the operator judges that it is difficult to capture in the hooks 3a ad 4a of theknitting needles flat knitting machine 30 through thecommunication device 54 or input to theflat knitting machine 30 after being recorded in a recording medium such as a disk and USB memory from the external memory device 55 so as to knit thefabric 9.
