Description

Technical Field

[0001] This invention relates to the field of down jacket manufacturing technology, and in particular to a zipper presser foot and a down jacket manufacturing method. Background Technology

[0002] Down-filled jackets have a certain thickness and compressibility, making them difficult to lay flat. Therefore, zippers are usually sewn on manually. Before attaching the zipper to the placket, the zipper tape on both sides needs to be aligned with the quilting lines on both sides of the down jacket, and alignment marks should be made on the zipper tape to ensure that the quilting lines on both sides of the down jacket are on the same horizontal line after the zipper is closed.

[0003] Many down jacket styles currently have multiple panels on the placket. To meet customer quality requirements, the placket needs to be trimmed after the zipper is installed. Manually trimming the placket with a cutter can easily cut the zipper, causing it to fray, and is also inefficient and can easily lead to employee fatigue. Summary of the Invention

[0004] Therefore, a zipper presser foot and a down jacket manufacturing method are needed to solve the problem that many down jacket styles have multiple placket seams, requiring trimming after the placket is installed to meet customer quality requirements. Manually trimming the placket with a cutter easily cuts the zipper, causing it to fray and resulting in low efficiency.

[0005] To achieve the above objectives, this embodiment provides a zipper presser foot, comprising:

[0006] First wall;

[0007] The second wall is parallel to the first wall and the second wall. The space between the first wall and the second wall is used to accommodate the zipper tape so that the zipper foot slides relative to each other along the length of the zipper. The outer wall of the first wall or the outer wall of the second wall is used to limit the cutter.

[0008] A third wall, which connects the first wall and the second wall together;

[0009] A connector is provided on the third wall, the second wall, or the first wall, and the zipper foot is assembled to one side of the cutter through the connector.

[0010] Furthermore, it also includes a first pressure plate, which is disposed on the outer side wall of the first wall, and the bottom of the first pressure plate is flush with the bottom of the first wall.

[0011] Furthermore, the first pressure plate is located at the front end of the first wall, and the connection between the front part of the first pressure plate and its bottom is arc-shaped.

[0012] Furthermore, it also includes a second pressure plate, which is disposed on the outer side wall of the second wall and spaced apart from the first pressure plate. The bottom of the second pressure plate is flush with the bottom of the first wall. The outer side wall of the first wall between the first pressure plate and the second pressure plate is used to limit the cutting blade.

[0013] Furthermore, the distance between the first wall and the second wall is 0.3 cm.

[0014] Furthermore, the bottom of the first wall and the bottom of the second wall are flush.

[0015] To achieve the above objectives, this embodiment also provides a method for manufacturing a down jacket, comprising the following steps:

[0016] An unfilled down jacket is provided, the down jacket having a filled area;

[0017] A zipper is sewn onto the placket of the down jacket;

[0018] Overlocking of the placket;

[0019] The connector of the zipper foot is assembled on one side of the cutter, so that the cutter fits against the outer side of the first wall or the outer side of the second wall of the zipper foot. The zipper foot is a zipper foot as described in any of the above embodiments. The zipper tape is placed between the first wall and the second wall, and the relative sliding between the zipper foot and the tape is controlled. The cutter trims the placket.

[0020] Furthermore, after "sewing a zipper onto the placket of the down jacket" and before "overlocking the placket," the following steps are also included:

[0021] The down jacket is filled with down from the sleeve side and the down filling area, and then the down filling area is sewn up.

[0022] Furthermore, the process of "sewing a zipper onto the placket of the down jacket" also includes the following steps:

[0023] The zipper is placed on the placket, and the template is placed on the zipper. The template has quilting grooves and zipper grooves. The quilting grooves correspond to the positions on the placket and the zipper where quilting threads are to be sewn, and the zipper grooves correspond to the positions on the placket and the zipper where quilting threads are to be sewn. The needle of the sewing machine moves along the quilting grooves and the zipper grooves respectively, thereby sewing the zipper onto the placket.

[0024] Unlike existing technologies, the above technical solution provides a fabric with a sewn zipper. The zipper foot is placed at the zipper, and the fabric tape is flipped up so that the tape is between the first and second walls. The fabric or cutter is pushed so that the first and second walls can slide smoothly along the length of the zipper. The cutter is aimed at the part of the placket to be trimmed, which can trim the placket and avoid uneven placket edges. Using the zipper foot can improve work efficiency.

[0052] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0053] Please see Figures 1 to 7 This embodiment of a zipper presser foot includes:

[0054] First Wall 11;

[0055] The second wall 12, the first wall 11 and the second wall 12 are parallel, the space between the first wall 11 and the second wall 12 is used to accommodate the zipper 2 tape 22 so that the zipper presser foot 1 can slide relative to each other along the length of the zipper, the outer wall of the first wall 11 or the outer wall of the second wall 12 is used to limit the cutter, and can also guide the movement of the sewing machine needle 4.

[0056] The third wall 13 connects the first wall 11 and the second wall 12 together;

[0057] Connector 16 is provided on the third wall 13, the second wall 12 or the first wall 11, and the zipper foot 1 is assembled to one side of the cutter through connector 16.

[0058] The outer wall of the first wall 11 or the outer wall of the second wall 12 is used to limit the cutting blade. This means that the blade surface of the cutting blade is attached to the outer wall of the first wall 11 or the outer wall of the second wall 12, and the cutting blade is supported by the first wall 11 or the second wall 12 to reduce the probability of the cutting blade deviating.

[0059] Please see Figure 5The zipper 2 consists of two fabric strips 22, each with a row of metal or plastic teeth, used to connect the edges of an opening (such as a garment placket or pocket opening). A pull tab 23 can pull the two rows of teeth into an interlocking position to close the opening. The continuously arranged teeth on the zipper 2 are called tooth chains 21, and a complete zipper 2 has two tooth chains 21 on the left and right sides. In use, the first wall 11 and the second wall 12 are located on the left and right sides of the fabric strip 22, that is, the fabric strip 22 is located between the first wall 11 and the second wall 12. The distance between the first wall 11 and the second wall 12 is preset to match the thickness of the fabric strip 22 so that the first wall 11 and the second wall 12 can slide smoothly along the length of the tooth chains 21.

[0060] Unlike existing technologies, the above technical solution provides a fabric with a sewn zipper. The zipper foot is placed at the zipper, and the fabric tape is flipped up so that the tape is between the first and second walls. The fabric or cutter is pushed so that the first and second walls can slide smoothly along the length of the zipper. The cutter is aimed at the part of the placket to be trimmed, which can trim the placket and avoid uneven placket edges. Using the zipper foot can improve work efficiency.

[0061] Please see Figure 1 According to one embodiment of this application, the zipper foot 1 further includes a first pressure plate 14, which is disposed on the outer side wall of the first wall 11, outside the space formed between the first wall 11 and the second wall 12. The bottom of the first pressure plate 14 is flush with the bottom of the first wall 11, which can flatten the zipper 2 and the fabric (such as a down jacket) below, and prevent wrinkles from forming on the zipper 2 and the fabric.

[0062] Please see Figure 1 and Figure 4 According to one embodiment of this application, in actual operation, the operator pushes the zipper 2 and the fabric towards the front end of the first wall 11. If the front end of the first pressure plate 14 is at a right angle, it is easy to rub against the fabric and cause wrinkles, affecting the sliding of the presser foot on the fabric. Therefore, the first pressure plate 14 is located at the front end of the first wall 11, and the connection between the front part and the bottom of the first pressure plate 14 is arc-shaped, reducing the probability of wrinkles in the fabric during sliding. The arc-shaped structure makes the sliding of the presser foot on the fabric smoother.

[0063] According to one embodiment of this application, the first presser foot and the first wall 11 are detachably connected, for example, the first presser foot and the first wall 11 are detachably connected by bolts and screw holes.

[0064] Please see Figure 2 , Figure 3 and Figure 4According to one embodiment of this application, the zipper presser foot 1 further includes a second presser plate 15. The second presser plate 15 is disposed on the outer side wall of the second wall 12, outside the space formed between the first wall 11 and the second wall 12, and spaced apart from the first presser plate 14. The bottom of the second presser plate 15 is flush with the bottom of the first wall 11. The outer side wall of the first wall 11 between the first presser plate 14 and the second presser plate 15 is used to limit the cutting blade and guide the movement of the sewing machine needle 4. The operator manipulates the cutting blade to trim the placket along the outer side wall of the first wall 11 between the first presser plate 14 and the second presser plate 15. Generally, the ends of the placket are trimmed straight for a more aesthetically pleasing appearance.

[0065] Please see Figure 4 According to one embodiment of this application, the connection between the rear part of the second pressure plate 15 and its bottom is arc-shaped, which reduces the probability of fabric wrinkles during sliding. The arc-shaped structure makes the presser foot slide more smoothly on the fabric.

[0066] Please see Figure 3 According to one embodiment of this application, the distance between the first wall 11 and the second wall 12 depends on the width of the actual thickness of the fabric strip 22. Preferably, the distance between the first wall 11 and the second wall 12 is 0.3 cm, and the thickness of the fabric strip 22 is slightly less than 0.3 cm.

[0067] According to one embodiment of this application, the connector 16 is an unclosed annular structure with screw holes provided at its two unclosed ends. The bolt passes through these two screw holes and gradually presses the two unclosed ends together, so that the two ends gradually approach each other and are then fixed on one side of the cutter, so that the blade of the cutter is attached to the outer wall of the first wall 11 or the outer wall of the second wall 12.

[0068] Please see Figures 1 to 7 This application also provides a method for manufacturing a down jacket, comprising the following steps:

[0069] An unfilled down jacket 8 is provided. The down jacket 8 has a filling area 5. The down jacket 8 will be filled with down through the filling area 5. The filling material in the down jacket 8 is most commonly goose down and duck down, and may also be mixed with some small feathers. The duck down is cleaned, sterilized at high temperature, and then filled into the garment to make the down jacket 8.

[0070] If the down filling area 5 is located on one side of the pocket, the down filling area cannot be sewn up when sewing the zipper 2; if the down filling area 5 is located on the sleeve or other parts, the down filling can be done from the down filling area 5.

[0071] A zipper 2 is sewn onto the placket of the down jacket 8. The zipper 2 consists of a connector made of two fabric strips 22, each with a row of metal or plastic teeth, used to connect the edges of the opening (such as the placket or pocket opening). A zipper pull 23 can be pulled into the interlocking position to close the opening. The continuously arranged teeth on the zipper 2 are called tooth chains 21, and a complete zipper 2 has two tooth chains 21 on the left and right sides.

[0072] Overlocking of the placket;

[0073] Assemble the connector 16 of the zipper foot 1 onto one side of the cutter, so that the cutter fits against the outer wall of the first wall 11 or the outer wall 12 of the zipper foot 1, reducing the chance of cutter misalignment. Please refer to [link / reference]. Figure 5 Place the fabric strip 22 of the zipper 2 between the first wall 11 and the second wall 12, control the relative sliding between the zipper presser foot 1 and the fabric strip 22, trim the placket with a cutter, and pre-set the distance between the first wall 11 and the second wall 12 to match the thickness of the fabric strip 22 so that the first wall 11 and the second wall 12 can slide smoothly along the length of the fabric strip 22.

[0074] Unlike existing technologies, the above technical solution provides a fabric with a sewn zipper. The zipper foot is placed at the zipper, and the fabric tape is flipped up so that the tape is between the first and second walls. The fabric or cutter is pushed so that the first and second walls can slide smoothly along the length of the zipper. The cutter is aimed at the part of the placket to be trimmed, which can trim the placket and avoid uneven placket edges. Using the zipper foot can improve work efficiency.

[0075] It should be mentioned that the traditional production process of down jackets 8 includes cutting pieces, quilting, filling, overlocking the placket, and sewing the placket zipper. Because the down jacket 8 has a certain thickness and compressibility after filling, it is difficult to lay it flat, making it inconvenient to attach the placket zipper after overlocking. Therefore, the traditional production process of down jackets 8 requires manually sewing the zipper onto the placket after filling. However, by using the zipper presser foot 1 of this application in the down jacket manufacturing process, the order of filling, overlocking, and sewing the placket zipper can be changed. Specifically, the zipper can be sewn first, then the down is filled, and finally the placket is overlocked.

[0076] According to one embodiment of this application, after "sewing a zipper onto the placket of the down jacket" and before "overlocking the placket," the following steps are further included:

[0077] The down jacket 8 is filled with down from the sleeve side and the down filling area 5. After filling, the down filling area 5 is sewn together, thus completing the production of the down jacket 8.

[0078] Please see Figure 6 and Figure 7According to one embodiment of this application, when "sewing a zipper on the placket of the down jacket 8", the following steps are also included:

[0079] The zipper is placed on the placket, and the template 3 is placed on the zipper. The template 3 is provided with quilting grooves 32 and zipper grooves 31. The quilting grooves 32 correspond to the positions on the placket and zipper where the quilting thread 7 will be sewn, and the zipper grooves 31 correspond to the positions on the placket and zipper where the quilting thread 7 will be sewn. The structure is as follows. Figure 6 As shown, the sewing machine needle 4 moves along the quilting groove 32 and the zipper groove 31 respectively to form the quilting thread 7 and the zipper thread, and then sews the zipper onto the placket. The structure is as follows. Figure 7 As shown.

[0080] Here is an explanation of how to make a down jacket:

[0081] 1. Quilting of cut pieces: Fill the space between two layers of fabric with down and sew them together with a sewing machine;

[0082] 2. Sewing the down jacket zipper: Using template 3, sew the zipper tape 22 to the placket using zipper stitch 6. Since the down jacket is not filled with down at this time, it can be laid flat on the work platform. Since template 3 is used to sew the zipper, the alignment of the chain teeth 21 with the placket is high, which can avoid manual alignment of the zipper later. It is worth mentioning that due to the presence of pockets, some down filling areas 5 cannot be filled from the sleeve side. When sewing the zipper, the down filling areas 5 need to be skipped first and then sewn after filling.

[0083] 3. Filling: Fill the down jacket with down from the sleeve side and the down filling area 5. After filling, sew the down filling area 5 and the zipper of the down filling area 5 together.

[0084] 4. Overlocking the placket: High-quality down jackets require overlocking the placket. Without a guide during the overlocking process, it heavily tests the worker's skill and can easily lead to problems such as crooked overlock lines. Using the zipper foot 1 of this application, the fabric tape 22 can be inserted between the two side walls of the zipper foot at the zipper seam 6. This not only replaces the manual action of pulling up the zipper tape, but also allows the zipper tape inserted between the two side walls of the zipper foot 1 to act as a guide.

[0085] 5. Trimming the overlock edge: Place the zipper foot 1 at the zipper, insert the fabric tape 22 into the zipper foot 1, that is, the chain teeth 21 are located between the first wall 11 and the second wall 12. Push the fabric or the cutter so that the first wall and the second wall 12 can slide smoothly along the length of the zipper tape 22. The cutter is aimed at the part of the placket to be trimmed on the fabric, and the part of the placket to be trimmed can be trimmed.
