[0037] The core of the present application is to disclose a sewing template with an open pocket and a sewing method to improve the sewing efficiency of clothes with elasticity and the consistency of finished products.

[0038] For those skilled in the art to better understand the present application, the following embodiments of the present application are described with reference to the accompanying drawings, and in addition, the following embodiments shown below do not limit the invention described in the claims in any way. In addition, all the contents represented by the following embodiments are not limited to the solutions necessary for the invention described in the claims.

[0039] As Figure 1 and Figure 2 shown, the present disclosure provides a sewing template with an open pocket, which mainly includes a bottom plate 10, a clamping plate 20, a cover plate 30 and a movable template 40.

[0040] Among them, the bottom plate 10 is used to carry the lining cloth, and the first sewing groove group 110 is opened on the bottom plate 10, and the lining cloth covers all the structures of the first sewing groove group 110 when placed on the bottom plate 10; the clamping plate 20 can be stacked with the bottom plate 10 to cooperate with the bottom plate, and the thickness direction realizes the pressing of the lining cloth, and then realizes the position fixing of the lining cloth; at the same time, as Figure 3 shown, the second sewing groove group 210 is opened on the clamping plate 20, and the first sewing groove group 110 includes the elastic groove group 120, and after the clamping plate 20 is stacked with the bottom plate 10 and adjusted to be in place on the bottom plate 10, the elastic groove group 120 can coincide with the second sewing groove group 210 to meet the subsequent quilting needs.

[0041] In particular, the elastic groove group 120 includes a plurality of parallelly arranged elastic grooves 1210 to separate the lining cloth, so that the finished product has a plurality of separated cavities to meet the loftiness and shape requirements of the finished product. At the same time, the bottom plate 10 is provided with a hook 130 at both ends of any elastic groove 1210, and it should be noted that the two ends of the elastic groove 1210 here specifically refer to the two ends of the elastic groove 1210 along its length direction. During use, the operator measures the length of the elastic, stretches the elastic and fixes both ends at the hook 130 position after stretching the elastic, so that further operation of the elastic is not required during quilting, and the elastic is kept in a uniform tension state by the fixing action of the hook 130.

[0042] It should be noted that the elastic fixed by the hook 130 is located in the overlapping area of the elastic groove group 120 and the second sewing groove group 210, and the setting of the hook 130 enables the elastic of different production sequences to maintain the same stretching state, ensuring the consistency of the finished product after elastic sewing of batch products, and enabling the sewing thread passing through the elastic groove group 120 and the second sewing groove group 210 to effectively sew and fix the elastic.

[0043] On this basis, the side of the card plate 20 away from the bottom plate 10 is used to set the fabric piece, that is, the card plate 20 is stacked with the bottom plate 10, and after the elastic band is fixed on the hook 130, a layer of fabric piece is laid on the card plate 20 again; and the cover plate 30 is used to be pressed and combined with the card plate 20 to realize the pressing and limiting of the fabric piece.

[0044] On this basis, the cover plate 30 is provided with a third sewing groove group 310, and when the cover plate 30 is buckled on the card plate 20, the third sewing groove group 310 corresponds to the first sewing groove group 110 one by one. Here, one by one specifically refers to that the groove structure provided in the first sewing groove group 110 is provided with a corresponding structure in the third sewing groove group 310, and after the cover plate 30 is stacked with the card plate 20 and the bottom plate 10, the groove structure in the third sewing groove group 310 is aligned with the groove structure provided in the first sewing groove group 110 in the thickness direction to meet the quilting requirement of the groove position of the first sewing groove group 110.

[0045] Further, as shown in Figure 4 The movable template 40 is used to limit the pocket structure. Specifically, the movable template 40 is separately provided with the bottom plate 10 and is provided as a three-section connected folding structure to carry the bag opening strip piece in the unfolded state, and after one side is folded and pressed to carry the bag cloth piece, the other side is folded and pressed to carry the bag cloth piece. The movable template 40 realizes the layer limiting of the bag opening strip piece and the bag cloth piece in the completely folded state, and at the same time, the fourth sewing groove group 410 is limited after the movable template 40 is completely folded. The first sewing groove group 110 is correspondingly provided with the bag opening groove group 140, and the fourth sewing groove group 410 and the bag opening groove group 140 at least partially coincide when the movable template is in the completely folded state to realize the sewing of the opening pocket structure.

[0046] The sewing template with an opening pocket provided by the embodiment of the present disclosure can limit the length of the elastic band through the hook 130, keep the stretching state of the elastic band during the sewing process, and does not need manual operation. It can not only improve the sewing efficiency of the elastic band and the consistency of the finished product, but also simplify the manual operation of the elastic band and improve the production efficiency. At the same time, the template of the opening pocket is provided as the movable template 40 which is separately provided with the floor, so that the operator can set the bag opening strip piece and the bag cloth piece on the movable template 40 during the sewing of the elastic band, and directly set the movable template 40 in the completely folded state after the sewing of the elastic band is completed, thereby improving the sewing production efficiency of the clothes.

[0047] Further, in order to realize the convenient assembly of the clamping plate 20 and the bottom plate 10 in place, avoid the deviation of the second sewing groove group 210 and the elastic groove group 120 to affect the quilting precision, in some embodiments of the present disclosure, the first sponge strip 150 is fixedly arranged on the bottom plate 10, the first sponge strip 150 is arranged on both sides of the elastic groove group 120 in the width direction, and the first sponge strip 150 can be arranged on both sides of each groove in the elastic groove group 120 or only on both sides of part of the grooves in the elastic groove group. Compared with other area structures of the bottom plate 10, the first sponge strip 150 has greater friction, and the clamping plate 20 is limited by the contact of the end and the first sponge strip 150 to realize the assembly in place on the bottom plate 10; the first sponge strip 150 not only has lower cost, but also is easy to set, and can be quickly fixed on the bottom plate 10 by bonding to realize the quick and accurate positioning of the clamping plate 20.

[0048] Further, in the sewing template with an opening pocket provided in the embodiments of the present disclosure, the movable template 40 includes a first plate 420, a second plate 430 and a third plate 440 arranged in sequence in a single direction, wherein the first plate 420 and the third plate 440 are rotationally connected to the two opposite side edges of the second plate 430, that is, the first plate 420 and the third plate 440 can be folded from both sides to the second plate 430 to realize a laminated structure.

[0049] On this basis, the second plate 430 is used to carry the pocket strip piece, specifically, the first groove 4310 and the second groove 4320 are arranged on the second plate 430, the elastic pressing plate 43210 is arranged in the second groove 4320, and the movable template 40 can expose the second plate 430 completely after being unfolded, at which time the setting of the pocket strip piece on the second plate 430 can be carried out, and the pocket strip piece is arranged on the second plate 430 to cover the second groove 4320 and is limited by the pressing plate 43210. It should be noted that in some embodiments, the pressing plate 43210 in the second groove 4320 is arranged in the middle region of the second groove 4320, that is, the two sides of the pressing plate 43210 also have the groove space of the second groove 4320, and in order to meet the sewing requirement of the pocket strip piece, the pocket strip piece is arranged and limited by the pressing plate 43210, and at the same time, based on the folding of the pressing plate 43210, the pocket strip piece is laminated with the pressing plate 43210 from the two sides in the thickness direction of the pressing plate 43210, and the folding direction of the pocket strip piece based on the pressing plate 43210 is towards the first groove 4310; at the same time, in the movable template 40, after the first plate 420 and the second plate 430 are folded and pressed together, the first plate 420 covers the pressing plate 43210 and exposes part of the groove body of the second groove 4320, after the laminated structure of the pocket strip piece and the pressing plate 43210 is arranged, the movable template 40 is folded by the first plate 420 to laminate and press the pocket strip piece with the second plate 430, and at the same time, part of the groove body of the second groove 4320 is exposed to meet the subsequent quilting requirement.

[0050] Further, the third plate 440 is used to press the bag cloth piece. After the first plate 420 and the second plate 430 are stacked, the movable template 40 can set the auxiliary piece of the bag opening strip piece and the bag cloth piece on the top of the stacked structure formed by the two, and after all the piece structures required by the bag opening structure are set, the third plate 440 can be folded to be stacked with the second plate 430 to realize the pressing and limiting of all the pieces. It should be noted that the third plate 440 is provided with a third groove 4410 and a fourth groove 4420, and after the third plate 440 is folded and stacked with the second plate 430, the third groove 4410 corresponds to the first groove 4310, and the fourth groove 4420 corresponds to the area of the second groove 4320 which is not blocked by the first plate 420, so that after the movable template 40 is set on the bottom plate 10, it can be smoothly sewn with the fabric piece and other structures through part of the structure of the first groove 4310 and the second groove 4320, i.e., the fourth sewing groove group 410.

[0051] Similarly, since the movable template 40 is separately set relative to the bottom plate 10, both need to be assembled in place, and in order to realize the convenient assembly and accurate limiting of the movable template 40 on the bottom plate 10, the second sponge strip 160 is also fixedly arranged on the bottom plate 10, and the movable template 40 is in contact with the second sponge strip 160 through the end, and the second sponge strip 160 is used to realize the assembly in place on the bottom plate 10 by means of the larger friction relative to other areas, and the fourth sewing groove group 410 can be aligned with the bag opening groove group 140 in the first sewing groove group 110 for subsequent sewing.

[0052] Further, in the sewing template with an opening bag provided by the embodiment of the present disclosure, in order to reduce the problem of inconsistent finished product states of the same batch of products caused by the difference in the level of the operator, the embodiment of the present disclosure further provides a scale mark 170 on the bottom plate 10. Specifically, the scale mark 170 is arranged on one side of the elastic groove 1210. Since both ends of the elastic groove 1210 are provided with hooks 130, the scale mark 170 is arranged on the same side as a single hook 130 and is used in cooperation. In the use process, the operator can hang one end of the elastic on the hook 130 on the same side as the scale mark 170, and measure the unstretched elastic by the scale mark 170 to realize the standardized length measurement, cut the elastic of the corresponding length, and then hang it on the hook 130 on the other side after stretching, so that any operator can measure the elastic of a specific length, and after hanging the elastic, the elastic can be kept in the same or similar stretched state, thereby improving the uniformity of the stretched state of the elastic in the finished product.

[0053] Further, in some embodiments of the present disclosure, the cover plate 30 and the clamping plate 20 are both rotationally connected to one side of the bottom plate 10 and can be folded and clamped on the bottom plate 10. The cover plate 30 and the clamping plate 20 can be rotationally connected to the bottom plate 10 through structures such as adhesion, rotating shafts or hinges. The rotationally connected integrated structure can be pre-set to enable the cover plate 30 and the clamping plate 20 to be clamped on one side of the bottom plate 10 at a single position, thereby reducing positioning difficulty and improving accuracy, and avoiding the problem of dispersion of the cover plate 30 and the clamping plate 20 from the bottom plate 10 and the need to find alignment.

[0054] In addition, in some embodiments of the present disclosure, the second sewing groove group 210 includes two or more parallel connection grooves 220, so that the finished product has two or more elasticities, and the elasticities can be arranged in parallel and spaced apart, thereby achieving ordered partitioning of the finished product and improving the structure and loft of the finished product.

[0055] Further, for the first sewing groove group 110, it further includes a ponytail lining groove group 180 arranged at the neckline position and a quilting groove 190 perpendicular to the elasticity groove group 120. In actual production, the corresponding groove group can be selected according to product requirements to sew, thereby improving the universality of the opening pocket sewing template provided by the embodiments of the present disclosure. The ponytail lining groove group 180 and the quilting groove 190 can be quickly sewn by an automatic quilting machine, so that the finished product meets the sewing requirements of each area.

[0056] As shown in Figure 5 the present disclosure also provides a sewing method using the opening pocket sewing template provided by any of the above embodiments for automatic sewing. Since the opening pocket sewing template has the technical effects provided by any of the above embodiments, the sewing method also has the technical effects provided by any of the above embodiments, which will not be described herein.
