Description
- A device is disclosed for closing, by means of sewing, a toe of a tubular knitted article, such as a sock, a stocking, or a leg of a pantyhose. Also disclosed is a method for closing, by means of sewing, the toe of a tubular knitted article.
- In the hosiery industry, it is known to produce tubular knitted articles, such as stockings or socks, on a circular knitting machine, and to unload the complete tubular article, with an open end or toe, intended to be closed by means of sewing in a subsequent processing step. In some cases, the tubular knitted article is a leg of a more complex garment, in particular a pantyhose. The garment can be formed by two legs and by a body that can in some cases be knitted in a single operation on a knitting machine. According to more conventional methods, the garment is produced by joining two legs, formed by respective tubular knitted articles produced separately to one another. In some cases, the toe of the stocking or the toes of the legs of the pantyhose are closed in the same circular knitting machine that produces the garment or part thereof. More frequently, the toes of the tubular knitted articles, whether individual stockings, pantyhose legs or similar garments, are closed by sewing in separate machines, downstream of the knitting process. Sewing machines are used for this purpose, to which the tubular knitted articles are fed after they have been correctly oriented.
- As the closed toe of the tubular knitted article must adapt to the toe of the foot of the person wearing the garment, it is useful for the seam line to be curved rather than rectilinear and in particular to follow a convex profile, which approximates the curvature of the toes of the foot toes. To this end, devices have been designed,which feed the tubular knitted article to the sewing machine imposing a deformation on the toe of the tubular knitted article such that, by sewing according to a straight line, a curved seam line is obtained. Devices of this type are disclosed in
US4,609,419 and inDE2524238 . - In these known devices, the area of the tubular knitted article adjacent to the toe is clamped between a feed belt and an opposing surface. The belt is an endless belt and defines a closed path. The active branch of the closed path draws the tubular knitted article from an insertion area to a sewing area. In the insertion area, the belt forms a curve corresponding to the profile of the seam line to be formed on the toe. In the sewing area, the belt follows a rectilinear path. Due to the change of curvature of the belt from the insertion area to the sewing area, in the finished article the seam line takes a convex profile, which adapts to the profile of the foot toe.
- Due to the way in which the curved profile is formed, in the sewn tubular knitted article wrinkles form at the seam line, which can make the garment somewhat uncomfortable.
- Therefore, there is the need to improve the devices for sewing the toes of tubular knitted articles, such as stockings or pantyhose legs, in order to overcome or alleviate the aforesaid problems.
- To completely or partially solve one or more of the problems of the prior art, according to a first aspect a device for sewing a toe of a tubular knitted article, according to claim 1, is provided, comprising a continuous flexible member, configured and arranged to press with a branch thereof an end portion of the tubular knitted article against an opposing surface and to feed the tubular knitted article along a feed path from an insertion position toward and through a sewing area in which a sewing machine is arranged, for sewing the toe of the tubular knitted article. In the insertion position the branch of the continuous flexible member that presses the tubular article against the opposing surface forms a first curve. In the sewing area, the continuous flexible member co-acts with a convex deflector profile, along which the continuous flexible member is guided, and which imparts to the continuous flexible member a curvature with a convexity facing the same part as the convexity of the first curve of the continuous flexible member.
- With this arrangement, a seam is generated according to a curved line, the shape of which is defined by the first curve formed by the continuous flexible member. However, in the area in which the sewing machine acts the fabric of the tubular knitted article is not deformed, or is deformed to a limited extent, due to the deflector profile, and therefore the formation of wrinkles in the sewn article is prevented or reduced.
- The device can also comprise an inserter, to transfer the tubular knitted article from a first position to the insertion position between the continuous flexible member and the opposing surface. The first curve has a convexity facing in the direction of feed of the tubular knitted article from the first position to the insertion position.
- In some embodiments, the continuous flexible member forms, between the first curve and the convex deflector profile, a curved segment with a concavity opposite to the concavity of said first curve. In practice, along the active branch thereof, the flexible member follows an undulating profile.
- The deflector profile can be formed by an idler wheel, or by a stationary cam.
- Advantageously, the deflector profile can comprise a maximum point, positioned approximately at the sewing point of the sewing machine.
- In advantageous embodiments, the deflector profile is adjustable at least in a direction approximately orthogonal to the feed path of the tubular knitted article. Analogously, the idler and guide members that define the curve or curves of the flexible member in the insertion area of the tubular knitted article can also be adjusted. Said members can comprise a plurality of idler wheels and/or of stationary cam profiles, on which the continuous flexible member is guided.
- According to a further aspect, a method, according to
claim 15, is provided for sewing a toe of a tubular knitted article, comprising the steps of: - engaging an end of the tubular knitted article between an opposing surface and a continuous flexible member, which forms in the engaging area a curve with a convexity facing the toe of the tubular knitted article;
- transferring the tubular knitted article by means of the continuous flexible member along the opposing surface toward a sewing area, imparting to the toe of the tubular knitted article a curvature inverse to the curve of the continuous flexible member in the area of engagement;
- sewing the toe of the tubular knitted article by means of a sewing machine while feeding the toe of the tubular knitted article through a sewing area by means of the continuous flexible member, in the sewing area the continuous flexible member being curved according to a curvature having a convexity facing the sewing machine.
- The invention will be better understood by following the description and accompanying drawing, which shows practical non-limiting embodiments of the invention. More specifically, in the drawing:

The same reference numbers in different drawings identify the same or similar elements. Additionally, the drawings are not necessarily drawn to scale. Also, the following detailed description does not limit the invention. Instead, the scope of the invention is defined by the appended claims.
- Reference throughout the specification to "one embodiment" or "an embodiment" or "some embodiments" means that the particular feature, structure or characteristic described in connection with an embodiment is included in at least one embodiment of the subject matter disclosed. Thus, the appearance of the phrase "in one embodiment" or "in an embodiment" or "in some embodiments" in various places throughout the specification is not necessarily referring to the same embodiment(s). Further, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.
- In the following description reference is made to an exemplary embodiment of a device for sewing the toes of tubular knitted articles formed by already assembled pantyhose legs. Each tubular article is thus formed by one of the two legs that, joined to a panty, form a complex garment. Sewing of the toes of the two legs of a pantyhose takes place in sequence. However, as will be apparent to the person skilled in the art from the description below, the device can be easily modified to produce single tubular knitted articles, such as socks or stockings, or legs intended to be joined to each other to form a pantyhose.
- With initial reference to
Figs. 1 and2 , the device, indicated as a whole with 1, comprises a cluster 3 of members for inserting and feeding tubular knitted articles, and a stitcher orsewing machine 5.

idler wheels belt 7 by thegear motor 11. In some embodiments, one, some or all of theidler wheels curve curves intermediate idler wheel 15. In this way, as will be apparent below, seam lines can be made on two legs of a pantyhose, which have symmetrical shapes instead of being the same for the toes of the two legs. - A
convex deflector profile 25 is provided between theidler wheel 19 and theidler pulley 10, along the path of the active branch of thebelt 7. In the embodiment illustrated, theconvex deflector profile 25 is a stationary profile, formed in the manner of a cam. Thebelt 7 is guided around theconvex deflector profile 25 and slides thereon. It would also be possible to replace the stationaryconvex deflector profile 25 with a deflector wheel, for example mounted idle, around which thebelt 7 is guided. - The
convex deflector profile 25 has a convexity oriented in the same direction as the convexity of thecurves curves deflector profile 25 are all oriented in the direction indicated by the arrow C. Consequently, when guided around theidler wheels same belt 7 when it follows theconvex deflector profile 25. - The
convex deflector profile 25 follows a curve with amaximum point 25m. Themaximum point 25m can be advantageously positioned in the sewing area of thesewing machine 5, i.e. in the area in which the sewing needles of thesewing machine 5 act, area indicated with 27 in the drawing. The needles are not shown in the drawing. - In other embodiments, not shown, the
idler wheels deflector profile 25. In some embodiments, theidler wheels convex deflector profile 25, and any profiles in substitution of one or more of the idler wheels 13-19 can be made of materials with a low coefficient of friction, to facilitate sliding of thebelt 7. - The device 1 comprises an opposing surface that can be formed, completely or partially, by a supporting
surface 31. The supportingsurface 31 can extend along the active portion of the path defined by thebelt 7, at least in the section thereof where thebelt 7 forms thecurves convex deflector profile 25. In some embodiments, the supportingsurface 31 is at least partially formed by a movingplate 33, provided with a substantially vertical movement, in the example, orthogonal to the direction of feed F of the tubular articles. The movement of the movingplate 33 is indicated by the double arrow f33 and can be controlled by anactuator 35, for example a piston-cylinder actuator, or by an electric motor or other suitable actuator. - In the embodiment illustrated, the moving
plate 33 co-acts with a movingpresser 37, positioned above the supportingsurface 31 and provided with a movement parallel to the movement of the movingplate 33, indicated with the double arrow f37.Reference number 39 indicates an actuator that controls the movement according to the double arrow f37. The movingplate 33 and the movingpresser 37 are positioned one in front of the other to pinch there between the toe of the tubular knitted article to be sewn, as will be described below with reference to the sequence ofFigs. 3-15 , which show the operating cycle of the device. - In the embodiment illustrated, the device 1 also comprises an
inserter 41, which is configured and arranged to insert pairs of legs to be sewn transferring them from a first position to a second position, indicated hereinafter as insertion position, in which the toes of the legs are between the movingplate 33 and the active branch of thebelt 7. The insertion movement of the tubular articles performed by theinserter 41 is indicated by the arrow f41. In the embodiment illustrated theinserter 41 is configured to simultaneously insert two legs G1, G2 of a pantyhose Co between thebelt 7 and the supportingsurface 31 and therefore has a double configuration. In other embodiments, in particular if the tubular knitted articles to be sewn are not legs G1, G2 of a pantyhose Co, but single stockings, for example, theinserter 41 can be single, i.e., configured to insert tubular knitted articles one at a time between thebelt 7 and the supportingsurface 31. - In the example illustrated the
inserter 41 comprises twotubular members tubular members tubular member tubular member belt 7 and the underlying supportingsurface 31, with a movement described below. - Each tubular knitted article formed by the leg G1 or G2 can have, at the end of the toe to be sewn, an edge B that is removed by cutting after or during sewing of the toe. The seam line is located inside the edge B, so that this latter can be cut and removed from the finished article, leaving intact the seam that closes the respective toe of the leg G1 or G2, respectively.
- Operation of the device described above will now be illustrated in detail with reference to the sequence of
Figs. 3 to 15 .Figs. 3 and 4 show an initial step of positioning the pantyhose Co and in particular the two legs G1, G2. Thewings tubular members 43A 34B and the respective legs are stretched orthogonally to their longitudinal extension. - In the subsequent step illustrated in
Figs. 5 and 6 thewings tubular members belt 7, between it and the underlying movingplate 33, carrying out a movement according to the arrow f41. In practice, each tubular knitted article formed by the leg G1 or G2 has in this way been translated from a first position (Fig. 3 ) to an insertion position (Fig. 5 ). The respective convexities of thecurves belt 7 are facing the edges B of the two tubular knitted articles G1, G2, which are on the opposite part of the belt with respect to the initial position. - In the subsequent step (
Figs. 7, 8 ), the movingplate 33 and the movingpresser 37 are moved toward each other (arrows f33, f37 inFig.7 ) to pinch the two tubular knitted articles G1, G2 against thewings plate 33 and of the movingpresser 37 is such that the total bending stress applied on thewings - Subsequently (
Figs. 9, 10 ) thewings plate 33 and the movingpresser 37. In practice, the friction between the fabric of the legs and theelements presser 37 and the movingplate 33. - Once the wings have been retracted, the moving
presser 37 and the movingplate 33 are raised until the movingplate 33 is presses against the lower edge of thebelt 7. In this way the two toes of the two tubular knitted articles G1, G2 are pinched between the movingplate 33 and the lower edge of thebelt 7. The movingpresser 37 can be moved to a non-operating position, i.e., a raised position not in contact with the underlying tubular articles G1, G2. This new position is represented inFigs. 11 and 12 . - During the operations described above the
belt 7 is stationary. After reaching the position of theFigs. 11 and 12 , thebelt 7 can start moving according to arrow f7, to feed the two tubular knitted articles G1, G2 toward the sewing area. Each tubular knitted article G1, G2 is engaged along a curve defined by thebelt 7, between this latter and the movingplate 33. When thebelt 7 starts moving according to arrow f7 (Fig. 13 ), it draws each tubular knitted article G1, G2 by friction, according to the arrow F, along the supportingsurface 31 toward the sewing area, where thesewing machine 5 is located. - As a result of the curvature imparted to the
belt 7 by the idler wheels, when each tubular knitted article G1 and G2 follows the path of thebelt 7, adhering by friction to the lower edge of thebelt 7, it is deformed. The line of contact between tubular knitted article G1, G2 andbelt 7 is deformed and, as a consequence of this, the edge B of the tubular knitted article G1, G2 takes a concave shape. - Continuing the feed toward the sewing area, the tubular article G1, G2 remains in contact without sliding with the
belt 7 and therefore follows the curvature of theconvex deflector profile 25. While it is being fed, at themaximum point 25m of the curve defined by theconvex deflector profile 25, the tubular knitted article G1, G2 is sewn by thesewing machine 5, as represented schematically in the plan view ofFig. 14 . This figure shows an intermediate step of the operation to sew the leg G1. Reference L indicates the seam line that has been made on half of the toe of the leg G1 by the needle (not shown) of thesewing machine 5 that acts in thepoint 27. The edge B of the toe of the tubular knitted article G1 has been cut along the area involved by the seam L, while it still remains in the area that has not reached thepoint 27 in which sewing takes place. - In
Fig 15 a pantyhose Co has been completely sewn: the toes of the two tubular knitted articles represented by the two legs G1, G2 have been sewn along curved and convex seam lines L, which approximately follow the profile of the toe of the foot. The subsequent pantyhose, indicated here with C1, is being sewn: the first leg G1 of the pantyhose C1 has been sewn, the second leg G2 is being sewn. A third pantyhose C3 is standing by to be inserted into the operating position. - Due to the presence of the
convex deflector profile 25, in thepoint 27 in which sewing takes place the fabric of the tubular knitted article G1, G2 is forced to follow theconvex deflector profile 25 which locally annuls the deformation imposed on the knitted fabric by the movement imparted by thebelt 7 in the previous section of the feed path, between thecurves idler wheel curve deflector profile 25 are oriented in the same direction (arrow C), in the sewing area (point 27) in substance the fabric of the tubular knitted article is in a practically undeformed condition. Consequently, as the resulting seam line L is curved, due to the sum of the effects of thecurves convex deflector profile 25 on the knitted fabric of the tubular knitted article G1, G2, the fabric is sewn substantially without wrinkles.
