Description

Technical Field

[0001] This invention relates to clothing manufacturing processes, specifically to a manufacturing process for a belt buckle on a double-faced wool patchwork coat. Background Technology

[0002] An overcoat is an outer garment worn over regular clothing to protect against wind and cold. The hem typically reaches the waist or below. Overcoats generally have long sleeves and can be opened at the front and fastened with buttons, zippers, Velcro, or a belt. They serve both warmth and aesthetic purposes. Wool overcoats, usually made of pure natural wool, are particularly popular due to their superior appearance and comfort.

[0003] To accentuate the figure, common wool coats typically feature a waist-cinching structure such as Velcro, a belt, or a leather strap. For example, the utility model patent with authorization announcement number CN204259861U discloses a new type of double-breasted fitted wool coat with leather trim, including a body and sleeves. The waist of the body is equipped with a belt buckle, a waist-cinching pleat, and a belt, which can be tightened by passing the belt through the belt buckle at the waist.

[0004] Most existing belt buckles are sewn directly onto the garment in the most common way. The belt buckle protrudes from the garment body, which is rather awkward, reduces the smoothness of the coat, and affects its appearance. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned problems and provide a belt buckle manufacturing process for a double-sided wool patchwork coat. This belt buckle manufacturing process can embed the belt buckle into the body of the coat, improving the flatness of the coat and making it more beautiful.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A manufacturing process for the belt buckle of a double-faced wool patchwork coat includes the following steps:

[0008] (1) Prepare two garment bodies; cut an embedding groove on the vertical splicing edge of the first garment body, the embedding groove including one long side and two short sides;

[0009] (2) Prepare the front buckle; the width of the front buckle is less than the width of the embedding groove;

[0010] (3) Sew the two ends of the front buckle to the two short sides of the embedding groove respectively;

[0011] (4) Sew the two garment bodies together;

[0012] (5) Complete the processing to obtain the embedded front belt buckle.

[0013] In a preferred embodiment of the present invention, in step (1), the vertical splicing edge of the second garment body is broken;

[0014] After the seam was broken, the vertical seam of the second garment body was divided into two seam pieces.

[0015] In a preferred embodiment of the present invention, in step (2), the front buckle is obtained by the following means:

[0016] Cut to obtain a rectangular front buckle blank;

[0017] Make seams around the front buckle blank;

[0018] Fold the front of the buckle blank in half;

[0019] Flatten the folded front fastener blank along a route parallel to the fold line;

[0020] Using the flatbed line as the boundary, and maintaining a set distance, cut off the excess part at the open end to obtain the semi-finished front buckle strap;

[0021] Flip the outer side of the semi-finished front buckle to the inner side to obtain the finished front buckle.

[0022] Furthermore, the outer side of the front buckle of the semi-finished product is flipped to the inner side using a self-flipping device. The operation method is as follows:

[0023] The front fastener of the semi-finished product to be turned is manually put onto the sleeve, and the upper end of the front fastener of the semi-finished product is higher than the sleeve.

[0024] The flip-pull drive mechanism drives the flip-pull clip to extend from the top of the sleeve until the slot of the flip-pull clip is above the front buckle of the semi-finished product.

[0025] The flip-pull drive mechanism drives the flip-pull clamp to move downwards. During this process, the top of the front buckle of the semi-finished product first enters the locking groove of the flip-pull clamp. Then, the elastic pressure-bearing part of the flip-pull clamp approaches and is squeezed by the top of the inner hole of the sleeve, forcing the elastic pressure-bearing part to swing around its connection point towards the center of the sleeve, and driving the connecting part and the clamping part to swing synchronously. In the swing direction, the elastic pressure-bearing part and the connecting part are both misaligned with the fixed clamping piece. At the same time, the clamping part pulls the top of the front buckle of the semi-finished product towards the fixed clamping piece until the clamping part clamps the top of the front buckle of the semi-finished product onto the fixed clamping piece. At this time, the elastic pressure-bearing part is completely inserted into the inner hole of the sleeve and continues to move downwards.

[0026] The fixed clip and the elastic clip clamp the top of the semi-finished front buckle and retract it into the inner hole of the sleeve. They continue to move downwards, gradually pulling the semi-finished front buckle into the inner hole of the sleeve. Finally, it comes out from the bottom of the sleeve, thereby flipping the outer side of the semi-finished front buckle to the inner side to obtain the finished front buckle.

[0027] Furthermore, the front buckle strap is ironed.

[0028] In a preferred embodiment of the present invention, in step (2), a reverse buckle is prepared;

[0029] After sewing the two garment bodies together, sew the two ends of the reverse buckle to the reverse side of the garment body, so that the reverse buckle covers the front buckle.

[0030] Furthermore, the reverse buckle is obtained in the following way:

[0031] The rectangular reverse buckle blank is cut out, and the size of the reverse buckle blank is larger than the size of the front buckle blank;

[0032] Make seams around the perimeter of the reverse side of the buckle blank;

[0033] After the seam is broken, the four sides of the reverse buckle blank are divided into two single-sided pieces; the four sides of the reverse buckle blank include two opposite long sides and two opposite short sides.

[0034] For the long side, bend the single piece of material formed by the tear inward, and then sew the two bent single pieces of material together; repeat the above operation to complete the sewing operation of the two long sides.

[0035] For the two short sides, cut off one side of the fabric, leaving the other side intact for later sewing to the garment body. The advantages of having a reverse-facing fastener are twofold: first, it allows you to wear a belt on the reverse side of the garment, making it suitable for clothes that can be worn both front and back; second, it can cover the reverse side of the front fasteners and the opening fabric, improving the aesthetics when the reverse side is facing out.

[0036] In a preferred embodiment of the present invention, before step (3), a window opening fabric is prepared, wherein the window opening fabric has a contoured groove that is the same as the embedding groove;

[0037] Lay the windowed fabric flat on the front of the garment body with the embedded groove, and make the contoured groove of the windowed fabric correspond to the embedded groove of the garment body.

[0038] Sew the windowed fabric along the boundary of the contour groove onto the garment body;

[0039] Cut open at the two corners of the contour groove;

[0040] Turn the window fabric inside out to the reverse side of the garment and sew a visible stitch along the seam of the window fabric.

[0041] Fold the free end of the open-window fabric towards the reverse side of the garment.

[0042] Sew the windowed fabric along the folded edge to the reverse side of the garment.

[0043] Furthermore, after stitching a visible seam at the base of the seam of the openwork fabric, the periphery of the embedded groove of the garment body is ironed on both the front and back sides.

[0044] Furthermore, the folded window fabric is ironed.

[0045] In a preferred embodiment of the present invention, in step (4), two garment bodies are stacked together, with the vertical splicing edges of the two garment bodies located on the same side and the front sides of the two garment bodies located on the inside.

[0046] Flip up the seam of the second garment body that is away from the first garment body, and sew the seam of the second garment body that is close to the first garment body to the vertical seam of the first garment body to form a half-sewn structure.

[0047] Fold the edge of the second garment piece away from the first garment piece inwards, and sew the folded edge piece to the semi-sewn structure.

[0048] Compared with the prior art, the present invention has the following advantages:

[0049] The belt buckle manufacturing process of this invention can embed the belt buckle into the body of the garment, improving the flatness of the coat and making it more aesthetically pleasing. Attached Figure Description

[0069] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0070] Example 1

[0071] The belt buckle manufacturing process of the double-faced wool patchwork coat in this embodiment includes the following steps:

[0072] (1) See Figure 1-2 Two garment bodies are prepared, which are components of the coat. The two garment bodies are subsequently spliced ​​together using vertical edges. Both garment bodies are made of double-faced wool fabric with a double-layer structure. The belt buckle of this invention is set at the splicing point of the two garment bodies. An embedding groove 1-1 is cut on the vertical splicing edge of the first garment body 1. The embedding groove 1-1 includes one long side and two short sides. During cutting, a powder-sweeping sample is first made, and then the powder-sweeping sample is aligned with the first garment body 1. A cutting outline mark is formed on the first garment body 1 by sweeping powder. Cutting is performed along the cutting outline mark to obtain the embedding groove 1-1.

[0073] Make a seam in the vertical splicing edge of the second garment body 2; after the seam is made, the vertical splicing edge of the second garment body 2 is divided into two splicing edge materials 2-1.

[0074] (2) See Figure 3-7 Prepare window opening fabric 3, which has a contoured groove that is the same as the embedded groove 1-1.

[0075] Lay the window vent fabric 3 flat on the front of the first garment body with the insert groove 1-1, and align the contour groove of the window vent fabric 3 with the insert groove 1-1 of the first garment body; sew the window vent fabric 3 onto the first garment body along the boundary of the contour groove; cut the window vent fabric 3 and the first garment body at the two corners of the contour groove to facilitate the flipping of the window vent fabric 3; flip the window vent fabric 3 to the reverse side of the first garment body and sew a topstitch at the seam root of the window vent fabric 3; fold the free end of the window vent fabric 3 toward the reverse side of the garment body; sew the window vent fabric 3 along the folded boundary to the reverse side of the garment body.

[0076] Furthermore, after stitching a visible seam at the base of the seam of the openwork fabric 3, the periphery of the embedded groove 1-1 of the garment body is ironed on both the front and back sides.

[0077] Furthermore, the folded window fabric 3 is ironed.

[0078] The advantages of setting the above-mentioned openwork fabric 3 are as follows: On the one hand, by sewing the openwork fabric 3 onto the front of the first garment body and turning the openwork fabric 3 to the reverse side of the first garment body, the loose stop formed when the first garment body is cut into the insert groove 1-1 becomes a smooth structure formed by turning the fabric over, so that the front of the coat has a smooth and flat outline at the insert groove 1-1, making it more beautiful and preventing the stop from breaking; on the other hand, the openwork fabric 3 sewn on the reverse side of the first garment body has two ends in the long side direction of the insert groove 1-1. When the front buckle 4 is subsequently sewn onto the first garment body, the two ends of the openwork fabric 3 are sewn with the two ends of the front buckle 4, which can achieve quick and initial fixation of the front buckle 4 on the first garment body and increase the connection strength of the front buckle 4 on the first garment body.

[0079] (3) See Figure 8-10 Prepare a front buckle 4 and a back buckle 5; the width of the front buckle 4 is smaller than the width of the embedding groove 1-1; wherein, the front buckle 4 is obtained in the following way:

[0080] A rectangular front buckle blank 6 is obtained by cutting out the front buckle blank 6, which is also made of double-faced wool fabric. The front buckle blank 6 is sewed around its perimeter until it is split into a single layer of fabric. One of the split layers of fabric is taken and folded in half. The folded front buckle blank 6 is then sewn along a line parallel to the fold line. The excess part at the open end is cut off at a set distance along the sewing line to obtain a semi-finished front buckle. The outer side of the semi-finished front buckle is turned inside out so that the sewing line is hidden inside, thus obtaining the finished front buckle 4.

[0081] Furthermore, the front buckle 4 is ironed to form a flat strip front buckle 4. At this time, the thickness of the front buckle 4 is basically the same as the thickness of the garment body, so that the front buckle 4 will be flush with the surface of the garment body after being sewn into the embedding groove 1-1, resulting in a better appearance.

[0082] See Figure 11-13 The reverse buckle 5 is obtained in the following way:

[0083] A rectangular reverse buckle blank 7 is obtained by cutting, and the size of the reverse buckle blank 7 is larger than the size of the front buckle blank 6. The four sides of the reverse buckle blank 7 are sewed. After the sewing, the four sides of the reverse buckle blank 7 are divided into two single-sided pieces 7-1. The four sides of the reverse buckle blank 7 include two opposite long sides and two opposite short sides. For the long sides, the single-sided pieces 7-1 formed by the sewing are bent inward, and then the two bent single-sided pieces 7-1 are sewn together. By following the above operation, the sewing operation of the two long sides is completed, so that the two long side stops of the reverse buckle 5 form a smooth and flat structure.

[0084] The advantages of having a reverse buckle are twofold: first, it allows you to wear a belt on the reverse side of the garment, making it suitable for clothes that can be worn both inside out; second, it can cover the reverse side of the front buckle and the opening fabric, thus improving the aesthetics when the reverse side is facing out.

[0085] For the two short sides, cut off the single-sided material 7-1 on one side, and keep the single-sided material 7-1 on the other side to sew to the main body of the garment later.

[0086] (4) See Figure 14 The two ends of the front buckle 4 are sewn to the two short sides of the embedding groove 1-1 respectively. Specifically, the two ends of the front buckle 4 are first sewn to the two ends of the window fabric 3 in the long side direction of the embedding groove 1-1 respectively. Then, the front buckle 4 is sewn to the corresponding two short sides of the embedding groove 1-1 on the garment body so that the front buckle 4 is fixed in the embedding groove 1-1 of the garment body.

[0087] (5) See Figure 15-20 Place two garment bodies together, with their vertical seam edges on the same side and their front sides facing inwards. Fold up the seam edge 2-1 of the second garment body 2 that is away from the first garment body 1. Sew the seam edge 2-1 of the second garment body 2 that is close to the first garment body 1 to the vertical seam edge of the first garment body 1 to form a semi-sewn structure. Trim the edges of the semi-sewn structure with a lathe tool. Fold the seam edge 2-1 of the second garment body 2 that is away from the first garment body 1 (i.e., the folded seam edge 2-1) inwards and sew the folded seam edge 2-1 to the semi-sewn structure.

[0088] (6) See Figure 21 The two ends of the reverse buckle 5 are sewn to the reverse side of the garment body, and the reverse buckle 5 covers the front buckle 4.

[0089] (7) See Figure 22 After processing, the embedded front belt buckle is obtained.

[0090] Example 2

[0091] See Figure 25-29 In this embodiment, a self-flipping device is used to flip the outer side of the front buckle 12 of the semi-finished product to the inner side. The self-flipping device includes a workbench 8 and an inward and outward flipping mechanism set on the workbench 8. The inward and outward flipping mechanism has several sets, each including a sleeve 9 (the top is not necessarily a conical structure, but can be a straight structure, depending on actual needs), a flipping clamp 10, and a flipping drive mechanism for driving the flipping clamp 10 to reciprocate within the sleeve 9; the sleeve 9 is vertically fixed on the workbench 8; the top of the flipping clamp 10 is provided with a self-clamping structure, and the bottom of the flipping clamp 10 is connected to the flipping drive mechanism; the self-clamping structure includes two sets of symmetrically arranged self-clamping components, each set of self-clamping components including a fixed clamping piece 10-1 and an elastic clamping piece; the elastic clamping piece The clip includes an elastic pressure-bearing part 10-2, a connecting part 10-3, and a clamping part 10-4 for clamping the end of the semi-finished front buckle 12 into the fixing clip 10-1; one end of the elastic pressure-bearing part 10-2 is fixedly connected to the top of the flip-pull clip 10, and the other end of the elastic pressure-bearing part 10-2 is connected to the lower end of the connecting part 10-3; the top of the connecting part 10-3 is connected to the clamping part 10-4; the clamping part 10-4 extends downward, and a locking groove for accommodating the end of the semi-finished front buckle 12 is provided between the clamping part 10-4 and the connecting part 10-3; compared with the connecting part 10-3, the fixing clip 10-1 is closer to the center of the flip-pull clip 10, and the clamping part 10-4 is further away from the center of the flip-pull clip 10.

[0092] The working method of the above self-tilting device is as follows:

[0093] The semi-finished product front fastener 12 is manually placed onto the sleeve 9, with the upper end of the semi-finished product front fastener 12 higher than the sleeve 9. The flip-pull drive mechanism drives the flip-pull clamp 10 to extend from the top of the sleeve 9 until the locking groove of the flip-pull clamp 10 is above the semi-finished product front fastener 12. The flip-pull drive mechanism then drives the flip-pull clamp 10 downwards. During this process, the top of the semi-finished product front fastener 12 first enters the locking groove of the flip-pull clamp 10. Then, the elastic pressure-bearing part 10-2 of the flip-pull clamp 10 approaches and is squeezed by the top of the inner hole of the sleeve 9, forcing the elastic pressure-bearing part 10-2 to swing around its connection point towards the center of the sleeve 9, and causing the connecting part 10-3 and the clamping part 10-4 to swing synchronously. In the swing direction... The connecting part 10-3 is misaligned with the fixing clip 10-1; at the same time, the clamping part 10-4 pulls the top of the semi-finished front buckle 12 closer to the fixing clip 10-1 until the clamping part 10-4 clamps the top of the semi-finished front buckle 12 onto the fixing clip 10-1. At this time, the elastic pressure part 10-2 is completely inserted into the inner hole of the sleeve 9 and continues to move downward; then, the fixing clip 10-1 and the elastic clip clamp the top of the semi-finished front buckle 12 and retract it into the inner hole of the sleeve 9, and continue to move downward, gradually pulling the semi-finished front buckle 12 into the inner hole of the sleeve 9, and finally it comes out from the bottom of the sleeve 9, thereby flipping the outer side of the semi-finished front buckle 12 to the inner side to obtain the finished front buckle.

[0094] Furthermore, the flip-pull drive mechanism includes a flip-pull drive motor 11 and a flip-pull transmission assembly. The flip-pull transmission assembly includes a lead screw and a lead screw nut. The specific structure can be referred to the existing structure.

[0095] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
