Description of the invention (A7 B7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs (detailed description of the invention) [Technical Field to which the Invention belongs] The present invention relates to the technology of feeding cloth by pushing teeth of sewing machines, especially industrial sewing machines. [Known technology] The cloth feeding device of the sewing machine as shown in Figs. 3 and 4 is widely known. The cloth feeding device is a cloth pusher 1 that fixes the downstream end 2a 'fixed in the cloth feeding direction of the cloth feeding table 2 to Repeated movement back and forth on the upper and lower feeding shaft 5 and held on the two wrists 6, and the upstream end 2b in the feeding direction is fixed on the horizontal feeding shaft 7 that repeats the back and forth movement, and the horizontal cloth will be quickly knotted when possible. Feed the wrist 8. The reciprocating motion to the upper and lower feed shaft 5 is to rotate clockwise than the upper shaft 9 eccentric cam 10 ′ and to interlock the upper and lower feed lever 12, and to interlock with one of its lower ends at the possibility of rotation The other end is fixed on the upper and lower feed shafts and transmitted by the wrist body 14. In addition, the repeated movement to and from the horizontal feed shaft 7 is eccentric cam 11 than the upper shaft 9, and is connected to the horizontal feed rod 13, At its lower end—end to the possible return The lower linkage link 15 is linked above the other end in a possible rotation, and the lower end is fixed on the horizontal feed shaft 7 and transmitted by the wrist body 16. 3 and 4 in the figure are the needle lifter plate and the pressure needle plate, respectively. 17, 17, respectively, are the linkage link, the transmission adjustment link supported on the support shaft 19 in the machine under the possibility of rotation.

Description of the Invention (2) This is the exercise for the whole. As a result, the cloth is transferred between the cloth pushing teeth 1 and the presser plate 4. The movement trajectories of the downstream end (the front end of the tooth) A and the upstream end (the front end of the tooth) B of the cloth pushing tooth 1 in the feeding direction are shown in Fig. 5 respectively. These ellipse's and the amount of vertical movement at point A become smaller than the amount of vertical movement at point b. In addition, the cloth sandwiched between the needle presser plate 4 and the needle lifter plate 3 is transmitted by the horizontal movement amount on the needle lifter plate of the cloth pusher tooth 1. [Problem to solve the problem of the invention] As shown in FIG. 3 and FIG. 4, in the conventional cloth feeding device, when 2 pieces of cloth are sewn, the upper cloth is held only by the pressure plate 4 and is sewn under Since the cloth on the side is conveyed by the cloth pushing teeth 1, the cloth adjacent to the lower side of the cloth pushing teeth 1 is conveyed more than the cloth adjacent to the upper side of the presser plate. As a result, after the sewing, the lower cloth was loosened (wavy relaxation occurred locally) and the thread was loosened. Generally, in order to prevent the thread from falling off, the pressure of the presser plate is reduced, or the upper feeding device is installed. However, the former reduces the feeding ability during high-speed sewing, and the latter becomes a cause of complicated mechanism and price increase. In addition, as in the proposal disclosed in Japanese Patent Publication No. 53-24852, a reverse feed motion is added to the stage where the pusher recording needle plate is raised during the feed motion. However, the reverse feed motion is based on the pusher teeth. The whole action on the cloth not only reports that it is difficult to produce the correct feed tooth pitch, because the cloth in the sewing process will vibrate back and forth, so a misalignment will occur during operation. Because more importantly, because the friction between the cloth and the presser plate is smaller than the friction between the cloth and the cloth, the amount of back-off thread made in advance cannot be overcome. The purpose of this month is to prevent the cloth from escaping between multiple overlapping cloths when the cloth is pushed by the pusher of the hurry. A7

The horizontal feeding movement mechanism α of the cloth feeding device is arranged on the upstream side in the feeding direction, and the vertical feeding movement mechanism β is arranged on the downstream side in the feeding direction. The past phases coincide, and the rotation direction of the upper shaft 9 is rotated clockwise as in the past, and the horizontal feeding cam is moved 180 to the upper and lower feeding eccentric cams. . There are two reasons for making such changes in past examples, which will be described later. First, since it mostly overlaps with the description of the previous examples, the outline of its structure will be explained. The cloth feeding device pushes the cloth feed teeth 1 to fix the downstream end 2a 'in the cloth feeding direction of the cloth feeding table 2 on the cloth feeding shaft 5 which is repeatedly moved back and forth, and is held on the two wrists 6', and the cloth feeding direction is The upstream end 2b is fixed to the horizontal cloth feeding shaft 7 which repeats the movement back and forth, and is connected to the horizontal cloth feeding wrist 8 when possible. The reciprocating motion of the upper and lower feeding shaft 5 is to rotate clockwise in the direction of the eccentric cam 10 than the upper shaft 9 and to interlock the upper and lower feeding rods 12 at one end of the lower end to be able to rotate, and the other end is fixed. It is conveyed on the upper and lower feed shafts through the wrist body 14. In addition, the reciprocating motion of the horizontal feed shaft 7 is eccentric cam 11 than the upper shaft 9 and is connected to the horizontal feed rod π. At one of its lower ends, it is connected to the link 15 which may be rotated, and above its other end. Linked when possible, the lower end is fixed on the horizontal feed shaft 7 and transmitted through the wrist body 16. In the figure, 3 and 4 are the needle lifter and pressure plate, respectively. 17 and 18 are the linkage links, and the transmission adjustment links supported on the support shaft 19 in the machine under possible rotation. The cloth feeding device moves the upper and lower cloth feeding rods 12 up and down.

Description of the invention (up and down movements at 7 and B points. In addition, Figure 9 is a conventional example. Another reason is to position the apex on the feed teeth, such as As shown in Figures (3) and (4), it is more advantageous than the downstream side in the feed direction. The reason is to refer to the description of Figures 6 to 8. In addition, the components attached to Figure 7 The order of the symbols corresponds to the changing position of time. In this type of horizontal motion mechanism 0 :, the horizontal feed axis 7 is used as the origin, and the eccentric cam of the drive source is arranged on the positive side of the Y axis of the coordinate axis. At that time, where should the horizontal movement amount adjustment mechanism formed by the linkage link 15 '17 and the cloth feed adjustment link 18 be disposed, specifically, by using the configuration on the positive side of the X axis or the negative side of the X axis, The left and right poles (horizontal feed lever 13) of the swing movement of the horizontal feed wrist 16 (horizontal feed lever 13) ± 90. The swing angle is determined by seeing that the side becomes larger and the side becomes smaller. Specifically, as shown in FIG. 3 In the case of the conventional example shown in FIG. 4, the horizontal motion regulator Arranged in the first quadrant ([+ χ, + Ym, as shown in Fig. 7 (2), the right pole of the horizontal feed wrist 16 is carried.) The aspect (the upper side of the feed direction) of the shaking motion becomes smaller. The cloth feeding device of the present invention shown in FIG. 2 and FIG. 2 has a horizontal motion adjustment mechanism arranged in the second quadrant c [-x, + Ym). As shown in FIG. In the aspect (upstream side in the feeding direction), the swing motion becomes larger. For the above reasons, in order to use the position of the top point of the feed teeth as the downstream direction in the feeding direction ', the invention is shown in FIG. I and FIG. 2 The cloth device is more advantageous. Effectively bring the top position of the feed teeth to the feed direction and use the swing support of the horizontal movement amount adjustment mechanism to the horizontal feed rod and linkage link 17 = parent point movement, if the X component is changed It can be large. For this reason, the cloth rod 13 becomes longer, 2 as shown in Fig. 8; if the linkage rod η is shortened, that is, 1 paper size is applicable-National Standard ⑽ 297 (Please read the precautions on the back first) (Fill in this page again)

According to this method, as shown in FIG. 5 (3), the upper and lower apex 1 of the feed teeth are obtained to deviate from the feed direction. The H-step L can be the wrist 6 to the highest position, and the upper and lower eccentric cams 9 Phase 1 = The rightmost position of the horizontal movement of the feed and trajectory is adjusted by 90. After that, the feeding trajectory shown in Figure 5 (4) can be obtained. Finally, the details of the feed motion trajectory by the feed m pusher ^ will be described in section _⑴. The trajectory in the downstream end A in the feeding direction is the same trajectory as the conventional one in which the pushing teeth 1 ascend from the needle lifter 3 while moving in the forward feeding direction. At this point, in the track of the upstream end 8 in the feed direction, the amount of up and down movement D is higher than the up and down movement w, h (c > D) of point A, and when the pusher teeth are raised, the needle is lifted earlier than point A. It rises from the top (at 8 o'clock, 27 o, and b is the name.) The rise of point A to the upper position of the needle lifter 3 (258. ~ 271.) Is the trajectory of the movement in the reverse feed direction. The reverse feed amount G at this time is set to 10 to 30% of the forward feed amount E. Going one step further, in the downstream end A and upstream end B of the feed direction of the pusher tooth i, if the horizontal movement amount on the needle lifter plate is set to E, F, the full horizontal movement amount is K, L, and, If the distance from the positive feed start point of the pusher teeth to the upper vertex position is j, j, E / κ and F / L are 0.75 or more, and ι / κ and J / L are 0.3 or more. Therefore, it is possible to increase the continuous feed interval of the pusher teeth and increase the feed force. In addition, in order to obtain the above-mentioned feeding motion trajectory, it is necessary to use the rightmost point of the horizontal feeding wrist 8 as the reference time. ~ 90. The range is slowly adjusted. These relationships are the same as those shown in FIG. 10 (2) even in the case shown in FIG.

Furthermore, even in this feeding device, in order to obtain the above-mentioned conditions of the feeding movement trajectory, the up-and-down movement amount of 30 horizontal movement fulcrum points will be measured at the downstream end A in the feeding direction, and the upstream end B side in the feeding direction The amount of up-down movement in the up-down movement fulcrum 23 becomes almost the same as that shown in FIG. 1. As shown in Figures 1 and 11 above, the cloth feeding devices are in the initial stage of the cloth feeding motion cycle. "The upstream end B is faster than the downstream end A in the feeding direction of the pushing tooth 1." The top of the needle plate starts to rise, and the downstream end A is rising to the position of the needle lifter, because the upstream M's relative size of the upstream end b applies the CNS A4 specification (210 X 297 mm) ( (Please read the notes on the back before filling out this page)

本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) A712- Description of the invention (10) The reverse feed movement 'as shown in Fig. 1 (3 (3), two overlapping cloths 31 are held between the needle lifter 3 and the needle presser on the downstream side, only on the lower side. The upper side of the cloth is pushed by the cloth teeth: the upper side part of the cloth is reversely conveyed and pulled. Therefore, if the cloth is subsequently fed forward, the cloth may deviate and become a pre-reverse formation, and the cloth after sewing does not deviate. No slackening will occur. In addition, since each stitch is stitched under the stretched μ of the cloth, when the pulling force is released, that is, when the cloth leaves from the presser plate and the pushing teeth, the state of pulling force returns to the original state. The thread makes the sewing enemy pattern disappear. Also, the amount of cloth deviation varies with the fabric and the sewing direction, but you can move point B up and down under the condition of point 改变 A to change the inclination of pusher 1 The effect of reducing the tension of the cloth can be adjusted individually according to the cloth. In addition, as shown in Figure 1 and Figure Π, no matter what type of feeding device is used, it depends on the movement trajectory of Figure 10 Possibly realized. Secondly, referring to FIG. 12 and FIG. 11, the feeding method and feeding method of the sewing machine according to the present invention are described. The third embodiment of the device will be described. The cloth feeding device is a cloth feeding table 2 which extends the hanging foot 2c directly below the cloth pushing teeth 1 and pushes the cloth teeth by rotating the upper and lower shafts once to and fro. The horizontal feed shaft 32's motion transfer system gives horizontal motion, and uses the same number of revolutions as the upper shaft of the sewing machine to rotate the lower shaft 43 of the two motion transfer systems (final up and down feed link 39 and up and down feed link 47) Give up and down motion. In the horizontal feed shaft 32, the lower end of the feed table arm 34 is fixed, and the two arms 49a, 49b are approximately L-shaped. The upper end of the feed table wrist 34 is borrowed from the feed table shaft 33 to return to A7. 5. Description of the invention (11 One end of the feed table link 46 may be linked, and the other end of the feed table link 46 may be borrowed. The cloth table shaft 44 may be interlocked in the feed direction of the feed table 2 when it is retracted. Between the lower end of the feed direction of the feed table 2 and the upper side of the upper and lower feed arms 49, and the leading end of the wrist 49a The upper and lower feed links 47 may be linked in conjunction with the return movement. The lower end of the upper and lower feed links 47 and the wrist 49a The movement is performed by the eccentric shaft 51 of the upper and lower feed link, at the lower wrist 49b, the eccentric twist link bolt 57, and the eccentric cam link segment bolt 58 at the end of the return. The other end of the eccentric cam link movement 59 is fixed to the lower shaft 43, and the eccentric portion of the eccentric cam 53 which feeds the upper and lower feeds in conjunction with the returning movement. The upper end portion of the upper and lower feed links may be interlocked. The lower end portion of the upper and lower feed link 39 is linked by the upper and lower feed link eccentric shafts 40 so that the lower end portion of the drop foot 2 of the feed table 2 can rotate. The protrusion amount of the pusher teeth of the needle plate not shown is adjusted by adjusting the eccentricity of the upper and lower feed link eccentric shaft 40 and the upper and lower feed link eccentric shaft 51. In addition, the above components In the assembly, other such as the feed table shaft positioning bolt 35, the feed table positioning bolt 37, the feed table link seat gold 38, the feed table bolt 41, the E link 42, the feed table positioning bolt 45, and the feed table gold 48. Upper and lower cloth feed wrist bolts 50, E-link 52, upper and lower cloth feed eccentric cam screw detection eccentricity Wheel housing 54, the eccentric cam housing subject spiro%, down feed arm Sin is necessary, but the description thereof is omitted. In the cloth feeding device, if the drive mechanism of the sewing machine (not shown) is used as the upper paper standard, the national standard of Yin State (CNS > A4 specification 'C297 is issued>) (Please read the precautions on the back before filling in (This page) Install Γ 9 ---- Order --------- Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs -14- Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7_ (12) When the shaft (spindle) rotates, the lower shaft rotates in the direction of the arrow, and the up and down feed link 39 swings in the direction of the arrow (up and down direction). Based on this, the cloth pusher 1 gives a part of the up and down movement. Further The rotary eccentric cam link 59 in the direction of the arrow by the lower shaft 43 is swung in the direction of the arrow, and the upper and lower feed links 47 are swung in the direction of the arrow by the upper and lower feed wrists 49. In the cloth pushing tooth 1, the swing motion and the aforementioned As the synthesizer, the swing amount of the vertical feed link 39 is used as a synthesizer, and the upper and lower axes (spindles) are linked. At the same time, the horizontal feed axis 32, which is not illustrated, is moved back and forth at a predetermined angle in the direction of the arrow by not shaking Shake and feed the wrist 34 The swing motion is transmitted through the feed table link 46 to the feed table 2 in a horizontal motion. Even if the cloth pusher 1 is adjusted at the top vertex such as horizontal, or by determining the up and down swing amount of the upper and lower feed link 39 The eccentricity of the eccentric portion 43a of the lower shaft 43 and the eccentricity of the upper and lower feed eccentric cam 53 which determines the up and down swing amount of the upper and lower feed links 47 and the length ratio of each of the wrists 49a and 49b of the upper and lower feed arms 49 Adjustment, during the stage of the cloth feeding movement, when the cloth pushing teeth rise from the needle lifter plate, the cloth pushing teeth 1 can be raised first from the feeding direction side (operator side), or the whole cloth pushing teeth 1 can be raised simultaneously, or It will rise first from the downstream side (back side) in the feed direction. In addition, if the feed link 46 is inclined as shown in Fig. 13 (1) (2), the up and down movement direction of the feed table 2 can be formed to face the arrow direction respectively. Finally, after synthesizing the up-down movement and the horizontal movement, various movement trajectories as shown in Fig. 13 (3) can be obtained. In the cloth feeding device, the adjustment of the eccentricity of the above components and the like are further taken, such as As shown in Figure 13 (4), it is necessary to borrow the upper and lower feed links 3 The up and down shaking amount of 9 will increase the up and down shaking amount of the upper and lower feed link 47. This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling this page)- 15- A7 Wrist support of A7 V. Description of the invention (B) As shown in Figure 12 and Figure 13, the cloth feeding device, at the stage when the cloth pusher 丨 ascends from the top of the needle plate, has 3 pens upstream in the feed direction The downstream end rises quickly. The downstream end A rises to the upper position of the needle lifter board. The upstream end b can prevent the deviation between the multiple overlapping fabrics by reversing and feeding. Other advantages are second. That is, the amount of up-and-down shaking of the lower end A and the upper end b of the feed direction of the pusher teeth 丨 can be arbitrarily set. The cloth pusher ^ can rise from either end during the ascent from the needle lifter plate, but it is almost horizontal when it reaches the top vertex. By adjusting the inclination of the cloth pushing tooth 1, the movement trajectory of the feeding end of the cloth feeding tooth 1 to the downstream end A and the upstream end B can be arbitrarily determined. Furthermore, since the horizontal feed shaft 32 of the feed table arm 34 and the swinging fulcrum of the upper and lower feed arms 49 are used, the number of parts can be reduced, and space can be saved. Moreover, the feeding device is occasionally similar to one of the feeding devices P shown in FIG. 16, that is, the feeding device shown in FIG. 6 is that the feeding table 2 extends and hangs down just below the pushing teeth 1. Feet 2, c. Furthermore, the lower end of the feed table 2 in the feed direction is fixed to the horizontal feed shaft 32, and the upper end of the feed table 34 is supported by the feed table eccentric shaft 33 and supported on the hanging foot in a swingable state. At the end of 2a, the eccentric part 43 of the lower shaft 43, and the upper and lower feed link 39 can be supported by the lower and upper parts, and the upper end part can be rotated by the eccentric shaft 40 of the upper and lower feed link. Under the support. As shown in FIG. 16, the lower shaft 43 ′ is rotated by the deviation 43 a as the up-and-down rocking motion of the up-and-down feed link 39, and transmitted to the feed table 2, and the horizontal feed shaft The reciprocating motion of a predetermined angle of 32, borrows the cloth feed arm 34, and transmits it to cloth feed table 2. The synthesized cloth pushing teeth 丨 perform (CNS) A4 ^ i ~ (21〇χ 297) Please read the back first Φ Precautions again · Tong i Dong · Page order -16- A7 B7 V. Description of the invention (M) Movement as shown in Figure 13 (3) (③). In addition, the amount of protrusion of the pusher teeth i from the needle lifter is adjusted by adjusting the eccentricity of the feed table eccentric shaft 33 '' and the upper and lower feed link eccentric shaft 40 '. The feeding device shown in FIG. 16 is similar to the feeding device of the present invention, but the feeding table eccentric shaft 33 is located on the downstream side of the feeding direction near the pushing tooth 1, and the feeding table eccentric shaft 33 is used. As a fulcrum, since the feed link eccentric shaft 40 is positioned above and below the cloth pusher j, the cloth pusher 1 moves up and down ', so the amount of up and down movement on the upstream side in the feed direction becomes larger than the amount of movement on the upstream side. Larger, so that during the feeding movement, the pushing teeth are raised from the top of the needle lifter plate, the pushing teeth 1 rise from the downstream side in the feeding direction, and the sewted cloth is loosened and undulated. In order to prevent these phenomena, even if the cloth pushing teeth 1 are tilted, the original cloth pushing teeth 1 are adjusted to have a horizontal shape on the top of the cloth pushing teeth 1, which is very limited. In addition, when the pusher teeth are raised from the top of the needle lifter during the feed motion, if the entire pusher teeth are adjusted to rise at the same time, the upstream side in the feed direction of the upper vertex becomes high and greatly inclined. In this way, the feeding device shown in FIG. 16 and the feeding device of the present invention seem to be different at all. Next, a fourth embodiment of the cloth feeding method and the cloth feeding device of the sewing machine according to the present invention will be described with reference to FIG. As shown in FIGS. 12 and 13, the feed arm 34 and the upper and lower feed links 39 of the feed device are both used as the feed arm and the upper and lower feed links 39 in the feed device. Same movement. As shown in the figure, the feed arm 34 " and the second feed arm 61 support the feed arm linkage link 62 by swinging to form a flat arm link. The upper ends of the feed table links 63 and 64, respectively.

Description of the invention (is lower end «may be τ is supported on the individual upper end of the individual shown as the feed table link 63, 64, = moved by ^ Courtesy such as the horizontal structure _ thing ^ Shake to read this back note and fill in the page when the links 63, 64 on each side to make it up the feed direction, then the feed table 2, the latch and: -s +, When the needle is tilted downward on the downstream side: 6 / rocking 'If it is tilted in the reverse feed direction, it will swing in the direction of the arrow. In the present invention, the feed table links 63 and 64 make the feed The upper side of the feed direction is inclined downward, and the lower end of each feed table link 63, 64 is smaller than the interval of the upper end, so the feed table link material on the upper side of the feed direction is more than the lower side. The cloth connecting rod is short. If you do this, the "lifting movement of the upper and lower feeding connecting rod 39" pushes the cloth teeth 1 on the surface of the needle lifter. In the stage, the upstream end B of the feed side 2 ”extends in the feed direction, and the upstream end B rises faster than the downstream end eight. The downstream end: the end A rises to the upper position of the needle lifter and the upstream end 6 performs a reverse feed motion. A plurality of overlapping cloths do not detach. At this time, by staggering the feeding table 2 " or the feeding table angle 65 of the feeding table links 63 and 64, the cloth can be pushed at the top vertex after all. The posture of 1 becomes horizontal. It is printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. Finally, the fifth embodiment of the feeding method of the sewing machine and the feeding device according to the present invention will be described with reference to FIG. 15. The cloth pusher 1 is fixed to the feed-side downstream end 2a of the feed table 2 and may be linked to the feed table link 68 when it is returned. The feed table link 68 is moved back and fixed to the horizontal feed shaft. 66, and the horizontal feed arm 67 may be linked with the return movement. Further, the feed end 69a and the feed link 69, 70 may be moved upward and downward in the feed direction of the feed table 2 respectively. Under installation, the lower end of each link 69, 70 may be placed in its original position under revolving Zhang scale is applicable to China National Standard (CNS) A4 specifications (210 X 297 mm) A7 A7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (〖6) Individually send the cloth wrists 71 and 72 up and down. One end of each of the upper and lower feed wrists 71 and 72 may be placed on the individual machine shafts 71a and 72a under the possibility of return. The other ends are fixed to the individual cam shafts 73 and 75 and overlap the air feed cams 74 and 76. Cam grooves 74a, 76a. The cam shafts 73 and 75 borrow the belt and the gear shaft from the lower shaft of the figure, and the upper shaft 丨 rotates, that is, a rotation for the up and down movement of the needle. The horizontal feeding component of the cloth teeth 丨 is obtained by shaking the horizontal feeding shaft 66 with the horizontal feeding wrist 67 in the direction of the arrow. In addition, the upper and lower feed components are obtained independently from the upstream side (operator side) and the downstream side (opposite operator side) of the feed direction of the pusher teeth. For example, on the upstream side, the upper and lower feed cams 76 rotate in the direction of the arrow by using the cam shaft as a fulcrum, and the upper and lower feed arms 72 swing the shaft 72a as the fulcrum in the direction of the arrow. The upper side of the feed table 2 is simultaneously moved by the upper and lower feed links. This series of movements is the same even on the downstream side. That is, because the feed components 之上 of the upper and lower sides of the pusher teeth 1 are independently obtained by the cam grooves 76a and 74a, respectively, the cam grooves 76a and 7 are shaped to arbitrarily push the cloth teeth. The amount of up-and-down shaking may increase the upstream side or increase the downstream side, which may be the same. Furthermore, the timing of the protrusion and the sinking timing of the upper side and the lower side of the pusher tooth 1 toward the needle lifter plate 3 can also be arbitrarily set. (Effects of the Invention) The present invention has the structure described above, and the effects exhibited by the invention are as follows. That is, the low-cost cloth feeding device can surely prevent the disconnection between the upper and lower cloths. The paper size conforms to the national standard (CNS) A4 specification ⑵〇χ 297 公 Chu. (Please read the precautions on the back before filling this page.) Binding, · -19-A7 B7___ V. Description of the invention (17) " " In addition, in the initial stage of the cloth feeding motion cycle, the entire cloth pushing teeth are used for the reverse transfer of the cloth. Compared with the conventional one, the cloth is held between the inclined plate and the pressure plate on the downstream side. The upper side of the cloth is pushed by the upper teeth of the cloth. The flow measurement, part of the reverse transmission, and drawstring, so that the effect of preventing the deviation of the cloth can be fixed, the sewing is correct, and the cloth will not vibrate back and forth during sewing. These effects are particularly remarkable when the feed amount is 1 mm or more. But it can also be expected below.
