[0002] A sewing template is a tool used to assist in sewing, widely applied to various parts and processes of garment production, such as pockets, collars, cuffs, and zippers. Some garment styles, such as the cuffs of sleeves, use curved elastic bands to maintain the aesthetic appearance of the final garment; however, this requires the sewing grooves in the sewing template to also be curved accordingly.

[0003] In related technologies, there is no specialized curved sewing template for sewing elastic bands and fabric together; it can only be achieved through manual sewing. However, this manual sewing is too slow, which is detrimental to improving the efficiency of garment production. Utility Model Content

[0004] This utility model discloses an arc-shaped sewing template and sewing device, which can improve the efficiency of garment production.

[0005] To achieve the above objectives, the first aspect of this utility model discloses an arc-shaped sewing template, comprising:

[0006] A base plate, configured to hold the fabric, the base plate having a first sewing groove and two first fasteners, the two first fasteners being located at both ends of the first sewing groove in the extending direction and spaced apart from the first sewing groove;

[0007] A cover plate is rotatably connected to the base plate. The cover plate is provided with a second sewing groove and two second fixing members. The first sewing groove and the second sewing groove are both arc-shaped sewing grooves. The two second fixing members are located at both ends of the second sewing groove in the extension direction and are spaced apart from the second sewing groove. When the cover plate is flipped relative to the base plate and covers the base plate, the second sewing groove corresponds to and communicates with the first sewing groove. Each second fixing member is configured to be connected to the corresponding first fixing member to fix the two ends of the elastic band.

[0008] A guide assembly is disposed on the base plate and located on one side of the first seam groove along its width direction. The guide assembly extends along the extension direction of the first seam groove and is configured to fix the elastic band so that the elastic band extends along the extension direction of the first seam groove.

[0009] As an optional implementation, the guide assembly includes a support and a guide. The support is disposed on the base plate and located on one side of the first seam groove along its width direction. The guide is disposed on the support and extends from the support to the side adjacent to the first seam groove, such that the projection of the guide on the base plate covers the first seam groove. The guide is configured to fix the elastic band.

[0010] As an optional implementation, the guide includes a plurality of first guide portions and a plurality of second guide portions, the first guide portions and the second guide portions being arranged sequentially at intervals along the extension direction of the first sewing groove, and the second guide portions being disposed between the first guide portions and the base plate along the thickness direction of the base plate.

[0011] As an optional implementation, both the first guide portion and the second guide portion include a plurality of fishbone spikes spaced apart along the extension direction of the first sewing groove.

[0012] As an optional implementation, a pad is provided on the base plate, the pad extends along the extension direction of the first sewing groove, and the support member is disposed on the pad.

[0015] As an optional implementation, the base plate is provided with two first seam grooves, which are spaced apart along a first direction. The cover plate is provided with two second seam grooves. When the cover plate is flipped relative to the base plate and covers the base plate, each second seam groove corresponds to and communicates with each first seam groove. The projection of the guide member on the base plate covers the two first seam grooves.

[0016] Wherein, the first direction intersects with the extension direction of the first seam groove.

[0017] As an optional implementation, along the first direction, each of the first fasteners is located between the two first sewing grooves.

[0018] Secondly, this utility model also discloses a sewing device, including a machine base and an arc-shaped sewing template as described in the first aspect, wherein the arc-shaped sewing template is disposed on the machine base.

[0019] Compared with the prior art, the beneficial effects of this application are:

[0020] This utility model provides an arc-shaped sewing template and sewing device. It features corresponding first and second sewing grooves on a base plate and a cover plate, and two first and two second fixing members at both ends of the first sewing groove, connected to fix the ends of an elastic band. A guide component is positioned on one side of the second sewing groove along its width and extends along the first sewing groove. Since both the first and second sewing grooves are arc-shaped, the guide component is configured to fix the elastic band, allowing it to extend along the first sewing groove. This allows the elastic band to be fixed in an arc shape via the first and second fixing members and the guide component. The arc-shaped elastic band and fabric can then be sewn together by the sewing equipment through the first and second sewing grooves of the arc-shaped sewing template, thereby improving garment production efficiency.

Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In this application, the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0030] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0031] Furthermore, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0032] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0033] In the garment manufacturing industry, sewing relies on skilled workers operating by hand. However, with rising labor costs and increasingly stringent consumer demands for garment quality—including novel designs, neat stitching, and fine workmanship—the inconsistent quality of traditional hand sewing is no longer sufficient. Sewing template technology is a new garment sewing process and technique. It utilizes automated equipment to create grooves of the required dimensions on an organic rubber board. By adding corresponding presser feet, needle plates, and other tools to the sewing equipment, sewing can proceed according to the template's grooved path, improving garment production efficiency and ensuring consistent quality.

[0034] Some garment styles, such as the cuffs of sleeves, use curved elastic bands to maintain the aesthetic appearance of the final garment. However, this requires the sewing grooves in the sewing template to also be prepared in a curved shape.

[0035] In related technologies, there is no specialized curved sewing template for sewing elastic bands and fabric together; it can only be achieved through manual sewing. However, this manual sewing is too slow, which is detrimental to improving the efficiency of garment production.

[0036] In view of this, this application discloses an arc-shaped sewing template and sewing device. A base plate is used to hold the fabric. The base plate and the cover plate are rotatably connected. The base plate has an arc-shaped first sewing groove and two first fixing members located at both ends of the first sewing groove's extension direction. When the cover plate is flipped relative to the base plate and covers it, the second sewing groove corresponds to and communicates with the first sewing groove. Each second fixing member is connected to its corresponding first fixing member to fix both ends of the elastic band. A guide component is provided on one side of the first sewing groove along its width direction, extending along the first sewing groove's extension direction to fix the elastic band, so that the elastic band also extends along the first sewing groove's extension direction. Through the cooperation between the first fixing member, the second fixing member, and the guide component, the elastic band can extend along the first sewing groove's extension direction and be fixed, thus allowing the elastic band to be fixed in an arc shape. This allows the elastic band and fabric to be sewn together by the sewing equipment, achieving an arc-shaped wrinkling effect, thereby improving garment production efficiency.

[0037] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0038] The curved sewing template 100 of this application can be applied to a sewing device 200 (such as...). Figure 4 As shown), the sewing device 200 is used to sew the elastic band 4 and the fabric 5 together in the curved sewing template 100.

[0039] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the arc-shaped sewing mold disclosed in the embodiments of this application when it is opened. Figure 2This is a schematic diagram of the structure of the arc-shaped sewing mold disclosed in this application when it is closed. The arc-shaped sewing mold 100 of this application includes a base plate 1, a cover plate 2, and a guide assembly 3. The base plate 1 is configured to hold the fabric 5. The base plate 1 is provided with a first sewing groove 11 and two first fixing members 12. The two first fixing members 12 are respectively located at both ends of the extension direction of the first sewing groove 11 and are spaced apart from the first sewing groove 11. The cover plate 2 is rotatably connected to the base plate 1. The cover plate 2 is provided with a second sewing groove 21 and two second fixing members 22. The first sewing groove 11 and the second sewing groove 21 are both arc-shaped sewing grooves. The two second fixing members 22 are located at both ends of the extension direction of the second sewing groove 21 and are spaced apart from the second sewing groove 21. When the cover plate 2 is flipped relative to the base plate 1 and closed on the base plate 1, the second sewing groove 21 corresponds to and communicates with the first sewing groove 11. Each second fixing member 22 is configured to be connected to the corresponding first fixing member 12 to fix the two ends of the elastic band 4. The guide component 3 is disposed on the base plate 1 and located on one side of the first sewing groove 11 along its width direction. The guide component 3 extends along the extension direction of the first sewing groove 11 and is configured to fix the elastic band 4 so that the elastic band 4 extends along the extension direction of the first sewing groove 11.

[0040] The arc-shaped sewing template 100 disclosed in this application uses two first fixing members 12 on the base plate 1 and two second fixing members 22 on the cover plate 2. When the cover plate 2 is closed on the base plate 1, the first fixing members 12 and the second fixing members 22 can be connected to each other, thereby fixing the two ends of the elastic band 4. This fixing direction can ensure that the relative position between the elastic band 4 and the fabric 5 remains accurate during the sewing process, and can avoid the elastic band 4 from sliding or twisting during the sewing process, thereby ensuring the sewing quality.

[0041] Firstly, the arc-shaped sewing template 100 of this application has a first sewing groove 11 on the base plate 1 and a second sewing groove 21 on the cover plate 2. When the cover plate 2 is closed on the base plate 1, the first sewing groove 11 and the second sewing groove 21 are correspondingly connected. Because the first sewing groove 11 and the second sewing groove 21 are correspondingly connected, and both the first sewing groove 11 and the second sewing groove 21 are arc-shaped grooves, on the one hand, it can provide a precise sewing path for the sewing needle, ensuring that the sewing follows a predetermined arc trajectory; on the other hand, it can make the sewing lines neat and aesthetically pleasing.

[0042] Secondly, the arc-shaped sewing template 100 of this application has a guide component 3 set on the base plate 1. The guide component 3 is located on one side of the first sewing groove 11 along its width direction. The guide component 3 can fix the elastic band 4 so that the elastic band 4 extends along the extension direction of the first sewing groove 11. In this way, by extending the elastic band 4 along the extension direction of the first sewing groove 11, it helps to sew the elastic band 4 with the fabric 5 in the correct direction during the sewing process. It also ensures the uniform distribution of the elastic band 4 throughout the arc-shaped sewing process, avoiding the phenomenon of local accumulation or uneven stretching of the elastic band 4, thereby further improving the sewing accuracy.

[0043] Furthermore, the arc-shaped sewing template 100 of this application is foldably connected to the cover plate 2 and the base plate 1, which facilitates the placement of the fabric 5 and elastic band 4 by the operator. Simply open the cover plate 2, fix the elastic band 4 along the guide component 3, place the fabric 5 on the base plate 1, and flip the cover plate 2 to close it on the base plate 1 to perform the sewing operation. This folding structure reduces the complexity of the operation, thereby improving the efficiency of sewing.

[0044] It is understood that the materials of the base plate 1 and the cover plate 2 can be epoxy board or acrylic board, etc., and this embodiment does not make specific limitations on this.

[0045] It is understandable that the thickness of the base plate 1 and the cover plate 2 is 2mm. Of course, other examples could be 1mm or 3mm, etc., and the specific thickness can be selected according to the actual situation.

[0046] It is understandable that, since the base plate 1 and the cover plate 2 are relatively thin, the flip-out connection between the base plate 1 and the cover plate 2 can be achieved by, for example, by using adhesive tape to bond one side of the base plate 1 and the cover plate 2 together, thereby achieving the flip-out connection between the base plate 1 and the cover plate 2.

[0047] In some embodiments, please refer to Figure 1 and Figure 2 The base plate 1 has a placement area 14 configured to indicate the placement position of the fabric 5, and a first sewing groove 11 is located within this placement area 14. By providing the placement area 14 and having the first sewing groove 11 within it, the operator can accurately place the fabric 5 in the area to be sewn, thereby improving sewing accuracy. Furthermore, since the placement position of the fabric 5 is clearly defined, the operator does not need to spend extra time repeatedly adjusting its position, thus saving operation time and improving garment production efficiency.

[0048] It is understood that the aforementioned placement area 14 is an area printed or drawn on the base plate 1 to indicate the placement position of the fabric 5.

[0049] It is understood that the width of the first seam groove 11 and the second seam groove 21 is in the range of 2-6mm, for example, it can be 2-3mm, 2-5mm, 3-6mm, etc., and for example, it can be 2mm, 4mm or 6mm.

[0050] When the width of the elastic band 4 is much wider than the width of the first seam groove 11, sewing through the first seam groove 11 can only partially sew the elastic band 4 to the fabric 5. This results in an unsightly appearance of the sewn elastic band 4 and fabric 5, and the connection between the elastic band 4 and fabric 5 is also weak. To solve this problem, please refer to... Figure 1 The base plate 1 is provided with two first sewing grooves 11, and the two first sewing grooves 11 are along the first direction X (e.g., Figure 1 The cover plate 2 is provided with two second sewing grooves 21, spaced apart in the left and right directions of the paper. When the cover plate 2 is flipped relative to the base plate 1 and covers the base plate 1, each second sewing groove 21 corresponds to and is connected to each first sewing groove 11. The projection of the guide member 32 on the base plate 1 covers the two first sewing grooves 11. The first direction X intersects with the extension direction of the first sewing groove 11. In this way, when sewing the elastic band 4 through the two first sewing grooves 11 and the corresponding two second sewing grooves 21, the wider elastic band 4 can be sewn together with the fabric 5 on both sides along its width direction, thereby improving the aesthetics of the sewn elastic band 4 and the fabric 5, and improving the connection and tightness between the elastic band 4 and the fabric 5.

[0051] Furthermore, the two first sewing slots 11 and the corresponding two second sewing slots 21 enable the sewing device 200 to simultaneously sew two sets of elastic bands 4 and fabric 5, thereby improving production efficiency. Moreover, the projection of the guide member 32 onto the base plate 1 covers both first sewing slots 11, ensuring that the elastic bands 4 can be accurately guided and fixed regardless of which first sewing slot 11 is used, thus improving sewing accuracy.

[0052] Optionally, please refer to Figure 1 Along the first direction X, each of the first fixing members 12 is located between the two first sewing grooves 11. By setting the first fixing members 12 between the two first sewing grooves 11, the elastic band 4 can be fixed by the two first fixing members 12 with more uniform force, thereby ensuring the quality of the sewing.

[0053] It should be noted that the above-mentioned arrangement of the first fixing member 12 along the first direction X between the two first sewing grooves 11 is performed when the width of the elastic band 4 is much wider than the width of the first sewing groove 11, and it is necessary to sew the elastic band 4 along both sides of its width direction through the two first sewing grooves 11 respectively. If the elastic band 4 is respectively provided above the two first sewing grooves 11, then the two first fixing members 12 can be respectively provided on both sides of each first sewing groove 11 along its extension direction.

[0054] It is understandable that the first fixing member 12 and the second fixing member 22 can specifically be: the first fixing member 12 is a fixing pin extending from the upper surface of the base plate 1 away from the base plate 1; and the second fixing member 22 is a fixing hole through which both ends of the elastic band 4 can pass, thereby allowing the elastic band 4 to be stretched and fixed to the template. When the cover plate 2 is closed on the base plate 1, the fixing pin can be inserted into the fixing hole. Of course, as another example, the first fixing member 12 and the second fixing member 22 can also be a snap fastener and a fixing hole, whereby the snap fastener can be inserted into the fixing hole when the cover plate 2 is closed on the base plate 1.

[0055] It is understood that the above-mentioned elastic band 4 can be natural elastic band, spandex elastic band or latex elastic band, etc., and this embodiment does not make specific limitations on it.

[0056] In some embodiments, please refer to Figures 1 to 3 , Figure 3 This is a schematic diagram of the structure of the guide assembly for fixing the elastic band disclosed in this application embodiment. The guide assembly 3 includes a support member 31 and a guide member 32. The support member 31 is disposed on the base plate 1 and located on one side of the first seam groove 11 along its width direction. The guide member 32 is disposed on the support member 31 and extends from the support member 31 to the side adjacent to the first seam groove 11, so that the projection of the guide member 32 on the base plate 1 covers the first seam groove 11. The guide member 32 is configured to fix the elastic band 4. First, by including the support member 31 in the guide assembly 3, and by disposing of the support member 31 on one side of the first seam groove 11 along its width direction, the support member 31 can provide a stable foundation for the guide member 32 and accurately determine the position of the guide member 32, thereby ensuring the accuracy of the extension direction of the elastic band 4. The operator only needs to place the elastic band 4 along the guide member 32 to ensure that the elastic band 4 is in the correct position, thereby improving the ease of operation for placing the elastic band 4.

[0057] Secondly, the support member 31 can support the guide member 32. In this way, even if the sewing device 200 vibrates or the operator is affected by external force during the sewing process, the support member 31 can ensure that the position of the guide member 32 does not change, thereby ensuring that the elastic band 4 can be sewn with the fabric 5 according to the predetermined trajectory.

[0058] Furthermore, the guide member 32 extends from the support member 31 to the side adjacent to the first sewing groove 11, and the projection of the guide member 32 on the base plate 1 covers the first sewing groove 11. This structure allows the elastic band 4 to be constrained on a predetermined path by the guide member 32 when it is placed on the guide member 32, thereby ensuring that the elastic band 4 does not deviate from the sewing trajectory and thus ensuring the accuracy of the sewing.

[0059] It is understood that the aforementioned support member 31 may be a long strip of fishbone or a long strip of fixing block, and this embodiment does not specifically limit it.

[0060] Optionally, please refer to Figures 1 to 3 The guide member 32 includes multiple first guide portions 321 and multiple second guide portions 322. The first guide portions 321 and second guide portions 322 are sequentially spaced along the extension direction of the first seam groove 11, and the second guide portions 322 are disposed between the first guide portions 321 and the base plate 1 along the thickness direction of the base plate 1. By sequentially spaced the first guide portions 321 and second guide portions 322 along the extension direction of the first seam groove 11, and the second guide portions 322 are located between the first guide portions 321 and the base plate 1 along the thickness direction of the base plate 1, on the one hand, the first guide portions 321 and second guide portions 322 can form a multi-layered guide structure in the thickness direction of the base plate 1, limiting the elastic band 4 from different heights, thereby making the elastic band 4 more securely fixed. On the other hand, the spaced arrangement of the first guide portions 321 and second guide portions 322 can make the force on the elastic band 4 more uniform along the extension direction of the first seam groove 11, thereby avoiding the situation where the elastic band 4 is subjected to excessive local force and shifts or deforms.

[0061] It is understandable that the first guide portion 321 and the second guide portion 322 have the same length along the extension direction of the first seam groove 11, which can be 1cm, 2cm, or 5cm, etc. This allows the elastic band 4 to be subjected to a more uniform force along the extension direction of the first seam groove 11. For example, taking the length of the first guide portion 321 and the second guide portion 322 along the extension direction of the first seam groove 11 as 5cm, then along the extension direction of the first seam groove 11, a first guide portion 321 is set every 5cm above the elastic band 4, and a second guide portion 322 is set every 5cm below the elastic band 4, with the first guide portion 321 and the second guide portion 322 arranged alternately.

[0062] In some embodiments, please refer to Figure 3The first guide portion 321 and the second guide portion 322 both include a plurality of herringbone spikes 321a spaced apart along the extension direction of the first sewing groove 11. Because both the first guide portion 321 and the second guide portion 322 include a plurality of herringbone spikes 321a spaced apart along the extension direction of the first sewing groove 11, these herringbone spikes 321a will make multi-point contact with the elastic band 4 when it is placed on the guide member 32. Compared with a smooth surface, the herringbone spikes 321a structure can increase the contact area with the elastic band 4, thereby improving friction and preventing the elastic band 4 from slipping during the sewing process.

[0063] In addition, both the first guide portion 321 and the second guide portion 322 include a plurality of fishbone spikes 321a spaced apart along the extension direction of the first sewing groove 11. This allows the fishbone spikes 321a to provide accurate guidance for the elastic band 4, ensuring that the elastic band 4 is aligned with the extension direction of the first sewing groove 11, thereby improving the sewing accuracy between the elastic band 4 and the fabric 5.

[0064] It is understood that the aforementioned support member 31 and the multiple fishbone spikes 321a can be integrally formed or separately formed and then connected together. This embodiment does not make specific limitations on this.

[0065] It is understood that the support member 31 and the fishbone spike 321a are made of the same material, such as plastic or rubber, and this embodiment does not make specific limitations on this.

[0066] Optionally, please refer to the following as well. Figure 2 and Figure 3 A pad 13 is provided on the base plate 1, extending along the extension direction of the first sewing groove 11, and a support member 31 is disposed on the pad 13. By providing the pad 13 and the support member 31, the height of the support member 31 can be increased through the pad 13, thereby creating a certain gap between the herringbone spike 321a connected to the support member 31 and the base plate 1. This provides sufficient space for the elastic band 4 or other components, preventing direct contact between the herringbone spike 321a and the base plate 1 and causing interference. On the other hand, the height of the herringbone spike 321a relative to the pad 13 can be adjusted through the pad 13, thereby accommodating elastic bands 4 of different thicknesses.

[0067] It is understood that the material of the aforementioned pad 13 can be polycarbonate, stainless steel or nitrile rubber, etc., and this embodiment does not specifically limit it.

[0068] Please see Figure 4 , Figure 4This is a schematic diagram of the sewing device disclosed in the embodiments of this application. In a second aspect, this application also discloses a sewing device 200, including a machine base 201 and an arc-shaped sewing template 100 as described in the first aspect above. The arc-shaped sewing template 100 is disposed on the machine base 201, so that the elastic band 4 and the fabric 5 can be sewn together on the machine base 201 through the arc-shaped sewing template 100.

[0069] The following is a brief description of the sewing process of elastic band 4 and fabric 5 using the curved sewing template 100 of this application:

[0070] First, fix both ends of the elastic band 4 at the first fixing member 12, so that the elastic band 4 is above the multiple fishbone spikes 321a. Then, adjust the elastic band 4 at intervals to be below the fishbone spikes 321a, so that the elastic band 4 is fixed along the first sewing groove 11. Then, place the fabric 5 above the elastic band 4 according to the indication of the placement area 14, and align the edge of the fabric with the edge of the placement area 14. Cover the cover plate 2 on the base plate 1, place the arc sewing template 100 on the machine table 201 for sewing, and sew along the extension direction of the first sewing groove 11. After sewing is completed, open the cover plate 2 and take out the sewn fabric 5 and elastic band 4.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
