Description

TECHNICAL FIELD

[0001] The present application relates to the field of automatic sewing technology, in particular to a shirt collar sewing template with a collar stay cutting line and a shirt collar sewing method. BACKGROUND

[0002] A collar stay, usually referred to as a small accessory for enhancing the stiffness of a shirt collar, is also known as a "collar stay" or "collar bone", made of metal (such as steel or aluminum) or plastic, commonly in the shape of a long strip with a convex corner at one end. The collar stay is inserted into the shirt collar sewing workpiece, and the convex corner serves as the inner lining of the shirt collar corner. The collar stay needs to be removed during washing and ironing, especially for metal collar stays.

[0003] A removable shirt collar pocket with a collar stay includes a collar face on the front and a collar bottom on the back. The pocket opening is used to connect with the collar seat, and the collar bottom has an opening pocket body that accommodates the collar stay. The collar bottom is connected by pressing the seams of the collar bottom panel as the main body and the collar end panel at both ends of the collar. The specific manufacturing steps are as follows: first, fold the collar seat connecting edge of the collar bottom panel at both ends towards the collar corner, then connect the folded collar bottom panel and the collar end panel by sewing, the collar end panel forms the collar seat connecting edge at both ends of the collar bottom, and the collar bottom panel and the collar end panel are pressed to form two opposite pocket side edges of the opening pocket body that accommodates and guides the insertion of the collar stay. The collar bottom sewing piece and the edge of the collar panel are pressed again to obtain a collar pocket with an open collar seat connecting edge. The stitching of the second pressing overlaps with the stitching of the two opposite pocket side edges of the opening pocket body, and the stitching of the second pressing contains the pocket bottom segment of the collar stay pocket body.

[0004] Traditional sewing requires multiple markings and alignments before sewing, such as folding and pressing the inner insert, stacking the cutting line of the inner insert on the predetermined position of the collar bottom panel, which requires multiple processes to complete and is inefficient. The uniformity of the sewing stitches and the smoothness of the stitches require a high level of skill from the employees. The collar panel requires a lining adhesive, and the stacking of the collar panel and the adhesive varies in water intake at different locations of the collar panel. The difference in water intake directly determines the shape retention effect of the shirt collar, and manual operation of flat stacking and pressing cannot differentiate the water intake at different locations of the collar panel.

[0044] The specific embodiments of the present application will be further described in conjunction with the following examples. The following examples are only used to more clearly illustrate the technical solutions of the present application, and cannot be used to limit the protection scope of the present application.

[0045] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in other ways that are not exactly as described in this description, and it is understood that persons skilled in the art can make similar modifications without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0046] Secondly, the "one embodiment" or "embodiment" referred to herein can include specific features, structures or characteristics contained in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

[0047] As Figures 1-6As shown, the embodiment has a shirt collar sewing template with a collar stay cutting line, which comprises a bottom plate 1, a collar stay cutting line positioning plate 2, a push folding assembly 3 and a top plate 4; the bottom plate 1 has a collar bottom piece a bearing surface and two first presser needle grooves 101 for pressing the collar bottom piece a and forming two opposite pocket side edges of a collar stay opening pocket of the collar end piece b; the collar stay cutting line positioning plate 2 has a collar bottom piece pressing cover surface and a cutting line positioning side edge 201, and the collar stay cutting line positioning plate 2 can be removed and stacked on the bottom plate 1; the push folding assembly 3 is arranged correspondingly to the collar stay cutting line positioning plate 2, and the push folding assembly 3 is configured to removeably push and fold the collar bottom piece a along the cutting line positioning side edge 201 to form a cutting line folded edge a1 including the opening of the pocket; the top plate 4 has a collar end piece pressing surface and a second presser needle groove 401 which is through the first presser needle groove 101; the collar end piece pressing surface is fixedly provided with an elastic pressing strip 402 which is located on both sides of the second presser needle groove 401 and is arranged in a staggered manner with the push folding assembly 3.

[0048] Figures 1-6 The dashed lines represent the predetermined placement positions of the collar bottom piece, the collar end piece and the collar face piece.

[0049] The collar stay cutting line positioning plate 2 has a predetermined thickness, but the thickness is small, so the normal projection of the thick side of the cutting line positioning plate along the plate thickness direction is defined as the cutting line positioning side edge 201.

[0050] The shirt collar sewing process is as shown in Figure 7 The collar bottom piece a, the collar end piece b and the collar face piece c are placed on the template, and Figure 1 The inner surface of the obtained collar pocket is turned outward to obtain a shirt collar collar bottom as shown in Figure 2 The collar stay d is inserted through the opening of the collar bottom pocket, and the inserted state of the collar stay d is as shown in Figure 2 The left side collar angle of the collar bottom as shown, the inserted state of the collar stay d is as shown in Figure 8 The right side collar angle of the collar bottom.

[0051] When the template is used with a template machine, the sewing needle of the template machine passes through the needle groove and presses the piece, the needle groove extends in the corresponding template plane, and the needle groove is consistent with the preset stitch of the template machine. The first presser needle groove 101 determines that the collar stay pocket side edge stitch is straight, the distance between the two pocket side edges is fixed, and it is completely consistent with the size of the collar stay; due to the fabric and gesture, the manually sewn pocket side edges will have a distance between the two pocket side edges inconsistent with the actual size of the collar stay, which is easy to cause the collar stay to be inserted too loose or not inserted.

[0052] In actual production, one of the warp and weft of the collar top and the collar bottom is consistent with the length direction of the collar, and the other is consistent with the width direction of the collar, so the tangent fold edge a1 formed by the push-folding assembly 3 on the collar bottom cutting piece a is oriented at an acute angle with the warp and weft of the cutting piece, that is, the tangent fold edge a1 is diagonal, the stretchability of the fabric at the tangent fold edge a1 is relatively large, and the stretchability difference of the elastic fabric is more obvious. Manual operation to set the tangent fold edge a1 is prone to cause poor flatness of the tangent fold edge a1, the tangent fold edge a1 is flat, and the tension is uniform and does not surge.

[0053] The push-folding assembly has a predetermined height, and one of the functions of the elastic pressing strip is to compensate for the height of the push-folding assembly, so that the top plate 4 remains in a flat state after being pressed on the push-folding assembly, thereby fixing the position of the pressing needle groove. In addition, as mentioned in the above paragraph, the tangent fold edge a1 is diagonal, so the stitch extension direction obtained by the sewing needle walking along the second pressing needle groove 401 is also diagonal. The second function of the elastic pressing strip is to further fix the collar bottom cutting piece and the collar end cutting piece, so that the two opposite pocket side edges of the collar support opening pocket body tend to be more flat, the thread tension is uniform, and the distance between the two pocket side edges is fixed.

[0054] In some preferred embodiments, the push-folding assembly 3 includes a flat push limiting groove 301 and a push plate 302 movably arranged in the flat push limiting groove 301, and the push plate 302 has a push-folding edge 3021.

[0055] The push plate 302 has switchable push-folding positions and avoidance positions. The push plate 302 at the push-folding position is arranged on the first pressing needle groove 101 in the plate thickness direction, and the push plate 302 at the avoidance position avoids the plate surface side of the first pressing needle groove 101.

[0056] Figure 2 The middle top plate is in a hinged unfolded state, the left push plate is in an avoidance position, and the right push plate is in a push-folding position. Figure 3 The middle top plate is in a hinged unfolded state, the left collar support tangent positioning plate is in a state of cooperating with the push-folding assembly for push-folding, and the right collar support tangent positioning plate is in a removal state. Figure 5 、 6 The middle top plate is in a hinged folded state.

[0057] It can be understood that the template is used by being placed on a horizontal operation table, and the push plate 302 moves in a horizontal direction in the flat push limiting groove 301. During use of the template, the top surface of the collar support tangent positioning plate 2 is slightly lower than the bottom surface of the push plate 302, and the end corner folded part of the collar bottom cutting piece a is clamped between the collar support tangent positioning plate 2 and the push plate 302, and the clamping structure is in order from bottom to top as follows: the collar support tangent positioning plate 2, the end corner folded part a2, and the push plate 302.

[0058] In some preferred embodiments, the bottom plate 1 and the top plate 4 are each provided with a third presser foot slot 5 and a fourth presser foot slot 6, the third presser foot slot 5 is in communication with one of the first presser foot slots 101 at a first included angle α, and the fourth presser foot slot 6 is in communication with the other of the first presser foot slots 101 at a second included angle β, the first included angle α and the second included angle β are clamped with a stay insertion interval, and the third presser foot slot 5 and the fourth presser foot slot 6 are configured as a tangent fold a1 and a collar end cutting piece b.

[0059] The tangent fold a1 formed by the push-and-fold collar bottom is pressed by the third presser foot slot 5 and the fourth presser foot slot 6, which fixes the tension state of the tangent fold a1 and effectively connects the tangent fold a1 with the collar end cutting piece b, especially at the end of the third presser foot slot 5 and the fourth presser foot slot 6 away from the first presser foot slot 101, the stitch is flat, effectively overcoming the misalignment of the stitch end caused by the oblique tangent fold a1 and manual gestures during manual sewing. In the finished shirt collar, the tangent fold a1 intersects with the stay, which is beneficial to improve the shape retention performance of the shirt collar bottom cutting piece a after multiple stays are inserted.

[0060] In some preferred embodiments, the stay tangent positioning plate 2, the push-and-fold assembly 3, and the top plate 4 are correspondingly arranged in groups, and two groups of stay tangent positioning plates 2, push-and-fold assemblies 3, and top plates 4 are arranged at intervals on the top surface of the bottom plate 1.

[0061] The bottom plate 1 and the top plate 4 are provided with a fifth presser foot slot 7, which is located between the first presser foot slots 101 of the two groups of top plates 4. The function of the fifth presser foot slot 7 is to press and connect the collar bottom cutting piece a and the collar end cutting piece b, to avoid the end angle of the opposite pocket side edges of the collar end cutting piece b away from the tangent fold a1 and the stay opening pocket body from folding during the use of the template, and to reduce the time of the template operator to lay out and arrange.

[0062] The two end collar bottom cutting pieces a on the collar bottom cutting piece a have different push-and-fold directions, so the push-and-fold assembly 3 is arranged correspondingly, which stretches the fabric obliquely to overcome the predetermined fabric stretch to form the tangent fold a1, and the stay tangent positioning plate 2 corresponding to the push-and-fold assembly 3 is drawn away along the length extension direction of the tangent positioning side 201 or the tangent fold a1, which is beneficial to fix the shape of the tangent fold a1 and the fabric tension.

[0063] In some preferred embodiments, a cover plate assembly 8 is further included, which is removably superimposed with the bottom plate 1, and the bottom plate 1 and the cover plate assembly 8 are each provided with a sixth presser foot slot 801, which is configured to press the collar bottom cutting piece a, the collar end cutting piece b, and the pocket bottom edge of the pocket of the collar face cutting piece c, and the opening of the collar pocket at the collar seat sewing edge.

[0064] The stitching of the collar bottom piece a and the collar end piece b is further placed between the bottom plate 1 and the cover plate assembly 8, and the sewing needle of the template machine travels along the sixth presser needle groove 801 to form a presser stitch, and the presser stitch includes the collar pocket bottom edge. The excess edge of the collar pocket outer edge is cut off, and then the inner surface of the collar pocket is turned to the outer surface, the presser stitch of the collar pocket is tightened, and the collar pocket is pressed, and the collar of the shirt to be stitched with the collar stand is obtained.

[0065] As Figures 4-6 shown, in some preferred embodiments, the cover plate assembly 8 includes a removable stacked core plate 802 and a top cover plate 803, and the core plate 802 and the bottom plate 1 are configured to clamp and position the stitching of the collar bottom piece a and the collar end piece b;

[0066] The core plate 802 has a collar face piece bearing surface facing away from the bottom plate 1, and the collar face piece bearing surface is provided with an elastic water taking part 804, and the top cover plate 803 is provided with a water taking through hole 805 in the direction of the thickness of the plate, and the elastic water taking part 804 is matched with the water taking through hole 805 in concave-convex;

[0067] The collar face piece bearing surface is also provided with an anti-skid part 806.

[0068] Figure 5 The middle cover plate assembly is in a stacked state, Figure 6 The core plate of the middle cover plate assembly is stacked with the bottom plate, and the top cover plate is in a hinged open state.

[0069] Further, the material of the elastic water taking part 804 is foam.

[0070] When the stitching of the collar bottom piece a and the collar end piece b is stacked with the collar face piece c, the concave-convex matching between the elastic water taking part 804 and the water taking through hole 805 causes the collar face piece c to be lifted by the foam and positioned into the water taking through hole 805, and the part of the collar face piece c clamped flat by the core plate 802 and the top cover plate 803 is the main body part, and the part positioned into the water taking through hole 805 is locally convex relative to the main body part, which is beneficial to obtain different water taking amounts at different positions of the top surface and ensure that the collar angle of the shirt collar always bends towards the neck side of the wearer, avoiding the collar angle from being raised.

[0071] The anti-skid part 806 is used to fix the presser position of the collar face piece c obtained by the concave-convex matching between the elastic water taking part 804 and the water taking through hole 805, and specifically, the anti-skid part 806 is a layer of sandpaper fixed on the collar face piece bearing surface; the elastic water taking part 804 is symmetrically arranged in groups at both ends of the pressing area of the collar face piece bearing surface, the anti-skid part 806 is arranged along the sixth presser needle groove 801 and on one side or both sides of the sixth presser needle groove 801, and optionally, the anti-skid part 806 is arranged between the sixth presser needle groove 801 and the elastic water taking part 804; further, the anti-skid part 806 is also arranged between the two groups of elastic water taking parts 804 to fix the position of the middle section of the collar.

[0072] In some preferred embodiments, the elastic water-taking member 804 comprises a first water-taking block 8041 and water-taking strips 8042, the sixth needle slot 801 of the core plate 802 comprises a neck width through slot 8011 and a neck length through slot 8012 which are connected by a third included angle γ, the first water-taking block 8041 is arranged in the third included angle γ, and the water-taking strips 8042 are arranged at the side of the first water-taking block 8041 away from the neck width through slot 8011, and the size of the first water-taking block 8041 along the extension direction of the neck length through slot 8012 is greater than the size of the water-taking strips 8042.

[0073] The sewing needle of the template machine moves along the extension direction of the neck length through slot 8012.

[0074] Further, as shown in the figure, three water-taking strips 8042 are arranged at the side of the first water-taking block 8041 away from the neck width through slot 8011. The first water-taking block 8041 has a side edge consistent with the extension direction of the neck width through slot 8011 and the neck length through slot 8012.

[0075] In some preferred embodiments, the long edge direction of the water-taking strips 8042 is consistent with the extension direction of the neck width through slot 8011.

[0076] In some preferred embodiments, the elastic water-taking member 804 further comprises a second water-taking block 8043, and the second elastic water-taking member 804 further comprises a second water-taking block 8043 along the extension direction of the neck width through slot 8011, and the second water-taking block 8043 is arranged at the side of the first water-taking block 8041 away from the third included angle γ along the extension direction of the neck width through slot 8011; one end of the first water-taking block 8041 close to the second water-taking block 8043 has a missing corner, and the missing corner is located at the side of the first water-taking block 8041 away from the neck width through slot 8011.

[0077] The first water-taking block 8041 and the second water-taking block 8043 ensure that the neck width side of the shirt collar has the maximum water-taking amount, and the arrangement of the missing corner makes the water-taking amount gradually decrease from the neck width side to the inside along the neck length direction, so that the neck length direction at the neck angle is adapted to the curvature of the wearer's neck.

[0078] Further, the size of the first water-taking block 8041 along the extension direction of the neck width through slot 8011 is greater than the size of the second water-taking block 8043, and the water-taking amount of the neck angle at the neck width side is slightly greater than the local part connected with the collar stand, and compared with the neck angle, the local part connected with the collar stand tends to be flat, which is beneficial to improve the three-dimensional sense and shape retention of the length ends of the shirt collar.
