The welt sewing template 1 disclosed in the present embodiment can be applied to a sewing machine, and thus, when used in cooperation with the sewing machine, the multilayer welt cut pieces 30 are sewn to the fabric cut pieces 31 by one sewing. Specifically, the welt sewing template 1 includes a base plate 10, a cover plate 12, and a plurality of intermediate plates 11. The base plate 10 is provided with first slot 100, and the first slot 100 penetrates through two opposite sides of the base plate 10 in the thickness direction of the base plate 10, i.e., in the direction indicated by the upward arrow in fig. 3. Each intermediate plate 11 is provided with a second slot 110, in the thickness direction of the intermediate plate 11, the second slot 110 penetrates through two opposite surfaces of the corresponding intermediate plate 11, each intermediate plate 11 is rotatably connected to the bottom plate 10 respectively to form different postures relative to the bottom plate 10, the different postures include a first posture and a second posture, the first posture is a posture in which the intermediate plate 11 is approximately stacked on the bottom plate 10, the second posture is a posture in which the intermediate plate 11 forms an included angle relative to the bottom plate 10, when each intermediate plate 11 rotates to the first posture, the plurality of intermediate plates 11 are sequentially stacked on the bottom plate 10, and each second slot 110 is overlapped and communicated with the first slot 100. The cover 12 is rotatably connected to the base 10, the cover 12 is provided with a third slot 120, the third slot 120 penetrates through two opposite surfaces of the cover 12 along the thickness direction of the cover 12, when the cover 12 is rotated to be stacked on the base 10, the cover 12 is pressed on the middle plate 11, and the third slot 120 and the second slot 110 are overlapped and communicated.

It will be appreciated that in the first position, the intermediate plate 11 is superimposed over the base plate 10 and is substantially parallel to the base plate 10, with the intermediate plate 11 overlying the base plate 10. The second posture is a posture that the middle plate 11 rotates relative to the bottom plate 10 and forms a certain included angle, and when the middle plate 11 is in the first posture, the strip cutting piece 30 can be placed on the middle plate 11. The opening state of the welt sewing template 1 means that the cover plate 12 rotates to form a certain included angle relative to the middle plate 11, each middle plate 11 is in the state of the second posture, the covering state of the welt sewing template 1 means that each middle plate 11 is in the first posture, and the cover plate 12 rotates to be overlapped on the middle plate 11.

As can be seen from the above, the intermediate plate 11 of the present application may be a plurality of plates, such as two, three, four, five, etc., and the specific number of the intermediate plates 11 is not limited herein. In this embodiment, the process of sewing the multiple layers of welt cut pieces 30 using the welt sewing template 1 of the present application will be described by taking the middle plate 11 as an example. When the welt sewing template 1 is in a closed state, the middle plate 11 stacked on the bottom plate 10 is defined as a first middle plate 11a, the second welt groove 110 disposed on the first middle plate 11a is defined as a first sub-groove 110a, the welt cut piece 30 disposed on the first middle plate 11a is defined as a first welt 301, the middle plate 11 stacked on the first middle plate 11a is defined as a second middle plate 11b, the second welt groove 110 disposed on the second middle plate 11b is defined as a second sub-groove 110b, and the welt cut piece 30 disposed on the second middle plate 11b is defined as a second welt 302, as shown in fig. 3, the bottom plate 10, the first middle plate 11a, the second middle plate 11b and the cover plate 12 are sequentially arranged from bottom to top.

Please refer to fig. 4, fig. 4 is a schematic partial cross-sectional view illustrating a cutting piece placed on a welt sewing template 1 according to an embodiment of the present invention. Assuming that the welt sewing template 1 is in a covering state, when sewing, the cover plate 12, the second middle plate 11b and the first middle plate 11a are rotated to form a certain angle with the bottom plate 10, the cloth cut piece 31 is placed on the bottom plate 10, then the first middle plate 11a is rotated to be overlapped on the bottom plate 10 so as to be pressed and fixed on the cloth cut piece 31, and then the first welt cut piece 301 is placed on the middle plate 11a along the corresponding first sub-groove 110 a. Then, the second middle plate 11b is rotated to be overlapped on the first middle plate 11a to be fixed on the first attachment strip cutting piece 301 in a pressing manner, and then the second attachment strip cutting piece 302 is placed on the second middle plate 11b along the corresponding second sub-groove 110 b. Then, the cover plate 12 is rotated to be overlapped on the second middle plate 11b to be fixed on the second furring cut piece 302 in a pressing manner, so that the process of placing the cloth cut piece 31 and each furring cut piece 30 on the furring sewing template 1 is completed.

Finally, the first attachment strip cutting piece 301 and the second attachment strip cutting piece 302 can be fixed to the fabric cutting piece 31 by one-time sewing by passing a sewing needle through the third sewing groove 120, the second sewing groove 110 and the first sewing groove 100 in this order, thereby obtaining a semi-finished product cutting piece having the multilayer attachment strip cutting piece 30.

Known from the above-mentioned, the welt sewing template 1 of this application is through setting up polylith intermediate plate 11 between apron 12 and bottom plate 10, thereby can be between two adjacent intermediate plate 11, and place welt cut-parts 30 between apron 12 and the intermediate plate 11, consequently, when making up, can once make up polylith welt cut-parts 30 on cloth cut-parts 31, promptly, can range upon range of the polylith welt cut-parts 30 of sewing up simultaneously on cloth cut-parts 31, thereby can realize the simple and easy, high-efficient and high-quality production of the semi-manufactured goods cut-parts that have multilayer welt cut-parts 30.

Next, the detailed structure of the welt sewing template 1 will be described in detail with reference to the drawings.

In some embodiments, the bottom plate 10, the middle plate 11, and the cover plate 12 may be thin plates in order to improve the overall portability of the welt-sewing template 1. Alternatively, the bottom plate 10 may be a square, circular or other shaped thin plate, the middle plate 11 may be a square, circular or other shaped thin plate, and the cover plate 12 may be a square, circular or other shaped thin plate. As long as the attachment sewing template 1 can be used for placing the fabric cut pieces 31 and the individual attachment cut pieces 30, the shapes of the bottom plate 10, the middle plate 11, and the cover plate 12 are not related, and the shape of the bottom plate 10, the middle plate 11, and the cover plate 12 is not particularly limited in this embodiment. For example, the bottom plate 10, the middle plate 11 and the cover plate 12 may be square thin plates to make the shape of the welt sewing template 1 neat and easy to store.

Alternatively, in order to make the welt sewing template 1 lighter as a whole, the bottom plate 10 may be made of transparent plastic, such as transparent polyvinyl chloride (PVC), transparent Polycarbonate (PC) or transparent acrylic. In order to make the chassis 10 have a certain deformation resistance so that the chassis 10 can keep a placing surface for placing the fabric panel 31 as a flat surface when placing the fabric panel 31 on the chassis 10, thereby preventing the fabric panel 31 from being changed in shape or wrinkled, the chassis 10 may have a certain thickness. Illustratively, the base plate 10 may be a PVC sheet having a thickness of about 1 mm.

Optionally, in order to facilitate the sewing staff to observe the placement state of the sewn stitches and the strip cut pieces 30, the cover plate 12 may be made of transparent plastic, such as transparent polyvinyl chloride (PVC), transparent Polycarbonate (PC) or transparent acrylic. Meanwhile, in order to enable the cover plate 12 to have certain deformation resistance, when the attachment sewing template 1 is in a covering state, the attachment cutting pieces 30 can be better pressed, and the possibility that the attachment cutting pieces 30 are displaced in the sewing process is reduced. Illustratively, the cover plate 12 may be a transparent PVC sheet having a thickness of about 1 mm.

In some embodiments, since the middle plate 11 mainly serves to separate the multiple layers of strip panels 30, in order to reduce the distance between each strip panel 30 and the cloth panel 31 as much as possible, and to facilitate reducing the total thickness of the strip sewing template 1 in the closed state, the thickness t1 of the middle plate 11 and the thickness t2 of the cover plate 12 may satisfy: t1< t 2. Wherein t1 and t2 are both in mm. For example, where t2 is 1mm, t1 may be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, or 0.8 mm.

In some embodiments, the cover plate 12 and one side of the middle plates 11 are rotatably connected to the same side of the bottom plate 10, on one hand, the user can operate the welt sewing template 1 from one side of the bottom plate 10 conveniently, and on the other hand, the welt sewing template 1 can be applied to welt cut pieces 30 or fabric cut pieces 31 with the shape and area larger than that of the bottom plate 10, that is, because the bottom plate 10 is connected with the cover plate 12 and the middle plates 11 only through one side, the welt sewing template 1 does not restrict the welt cut pieces 30 or the fabric cut pieces 31 from other sides of the bottom plate 10, so that the welt cut pieces 30 or the fabric cut pieces 31 can be partially located outside other sides of the bottom plate 10, and the welt sewing template 1 can be applied to the welt cut pieces 30 or the fabric cut pieces 31 with the area larger than that of the bottom plate 10. Exemplarily, it can be known from the foregoing that the bottom plate 10, the cover plate 12, and the middle plate 11 may be square plates, and therefore, the cover plate 12 and the plurality of middle plates 11 may be rotatably connected to one side of the bottom plate 10 in the width direction, so that the bottom plate 10, the cover plate 12, and the middle plate 11 may have a larger area to provide the furring strip cutting piece 30, thereby facilitating the sewing of the furring strip cutting piece 30. It will be appreciated that in other embodiments, the cover plate 12 and the intermediate plates 11 may be pivotally connected to different sides of the base plate 10.

Alternatively, in order to realize the rotatable coupling of the cover plate 12 to the base plate 10, the cover plate 12 may be rotatably coupled to the base plate 10 or the intermediate plate 11 by a flexible adhesive tape, a hinge structure, or a hinge structure. Likewise, to achieve a rotatable connection of the intermediate plate 11 to the base plate 10, the intermediate plate 11 may be rotatably connected to said base plate 10 by means of a flexible adhesive strip, a hinge structure or a hinge structure.

It can be understood from the foregoing that, when the cover plate 12 and the middle plate 11 are stacked on the base plate 10, the third slot 120 on the cover plate 12 can be overlapped and communicated with the second slot 110 on the middle plate 11 and the first slot 100 on the base plate 10, and therefore, the number and the arrangement positions of the third slot 120, the second slot 110 and the first slot 100 can be the same. Illustratively, the number and the arrangement positions of the third slot 120, the second slot 110 and the first slot 100 are the same, and the shapes of the third slot 120, the second slot 110 and the first slot 100 are the same, so that the design and the manufacture of the welt sewing template 1 can be simplified.

It is understood that, in other embodiments, the number of the third slot 120, the second slot 110 and the first slot 100 may be different, for example, there are one third slot 120 and two second slots 110, the two second slots 110 can communicate with the one third slot 120, and the number of the first slot 100 can also be one or two, that is, the third slot 120 on the cover plate 12 can communicate with the second slot 110 on the middle plate 11 and the first slot 100 on the base plate 10 when the cover plate 12 and the middle plate 11 are stacked on the base plate 10, which is not particularly limited in this embodiment.

The present embodiment will be described by taking the first slot 100, the second slot 110 and the third slot 120 as an example, wherein the number, shape and position of the slots are the same

In some embodiments, since the second seam groove 110 is used for indicating the placement position of the attachment strip panel 30 and for avoiding the sewing needle in the process of sewing the attachment strip panel 30 to the fabric panel 31 so as to sew the attachment strip panel 30 at different positions of the fabric panel 31, the second seam groove 110 may be provided in a plurality of numbers, and the plurality of second seam grooves 110 are provided at intervals according to the placement position of the attachment strip panel 30. Correspondingly, the first slot 100 is also provided with a plurality of first slot 100 at intervals, the third slot 120 is also provided with a plurality of third slot 120 at intervals.

In one example, at least two of the second slot 110 are parallel to each other in the case that at least two strip 30 pieces are parallel to each other among the plurality of strip 30 pieces for placing the middle plate 11. Correspondingly, in order to achieve the effect of making the number, shape and position of the first slot 100, the second slot 110 and the third slot 120 the same, at least two first slots 100 are arranged in parallel, and at least two third slots 120 are arranged in parallel.

In another example, in the case where at least two strip panels 30 of the plurality of strip panels 30 for placing the middle plate 11 are staggered, at least two second slit grooves 110 are staggered. Accordingly, in order to achieve the same number, shape and position of the first, second and third slot 100, 110 and 120, at least two first slot 100 and at least two third slot 120 are alternately arranged.

Alternatively, the second slot 110 may be an elongated arc, rectangular, kidney, oval, or other shaped slot. It is understood that the second seam groove 110 is not particularly limited as to the shape of the second seam groove 110 as long as the second seam groove 110 can extend along the shape of the strip panel 30 so that the second seam groove 110 can escape to a sewing needle when the sewing needle sews the strip panel 30 to the cloth panel 31 along the shape of the strip panel 30.

Preferably, the second slot 110 may be a slot having a uniform width, so that the design and manufacturing process of the welt sewing template 1 is simple. It is understood that, in other embodiments, the second seam groove 110 may also be a non-uniform-width elongated groove, and the setting may be adjusted according to the actual sewing situation, which is not limited in this embodiment.

Several arrangements and shapes of the second slot 110 are illustrated below.

In one example, as shown in fig. 3, the number of the second slot 110 may be four, and the four second slot 110 may be arc slots with equal width, wherein three second slot 110 are spaced apart from each other in parallel on the middle plate 11, and the remaining second slot 110 is staggered with the three second slot 110 on the middle plate 11.

In another example, as shown in fig. 5, fig. 5 is a schematic view illustrating a second arrangement manner of the first, second and third slot slots 100, 110 and 120 according to an embodiment of the present invention, the second slot slots 110 may be three, one of the second slot slots 110 is an arc slot with an equal width, the remaining two other second slot slots 110 are rectangular straight slots, and the three second slot slots 110 may be arranged on the middle plate 11 in a staggered manner at the same point.

In another example, as shown in fig. 6, fig. 6 is a schematic view illustrating a third arrangement manner of the first, second and third slot slots 100, 110 and 120 according to an embodiment of the present invention, the second slot 110 may be six, the six second slot slots 110 are all rectangular straight slots, and the six second slot slots 110 are disposed on the middle plate 11 at intervals in parallel.

As can be seen from the above, the welt cut pieces 30 can be sewn at a plurality of positions of the cloth cut pieces 31 by using the welt sewing template 1 of the present application. When the attachment strip panel 30 is sewn at a plurality of positions of the fabric panel 31, the number of layers of the attachment strip panel 30 at each position may be different, for example: the three positions of the cloth cut pieces 31 are provided with the attachment strip cut pieces 30, wherein the number of the attachment strip cut pieces 30 at two positions is four, the number of the attachment strip cut pieces 30 at other positions is two, the maximum number of the attachment strip cut pieces 30 is four, and correspondingly, the middle plate 11 can be four.

It can be understood that the strip-like cut pieces 30 placed on the same middle plate 11 form the same layer of strip-like cut pieces 30, and when the number of layers of the strip-like cut pieces 30 at different positions of the cloth cut pieces 31 is different, the number of the strip-like cut pieces 30 forming the different layer of strip-like cut pieces 30 may also be different, that is, the number of the strip-like cut pieces 30 placed on different middle plates 11 may be different.

Illustratively, the welt cut pieces 30 are sewn on six positions of the cloth cut piece 31, wherein the three sewn welt cut pieces 30 are one layer, the other three sewn welt cut pieces 30 are two layers, the middle plate 11 is two, the two middle plates 11 are a first middle plate 11a and a second middle plate 11b from bottom to top, the first welt cut piece 301 placed on the first middle plate 11a is six, the six first welt cut pieces 301 are respectively placed corresponding to the six first sub-grooves 110a, the second welt cut piece 302 placed on the second middle plate 11b is three, and the three second welt cut pieces 302 are respectively placed corresponding to the three second sub-grooves 110 b.

As can be seen from the above, in order to meet different setting requirements of the strip panels 30, the number of the strip panels 30 placed on one middle plate 11 may be equal to the number of the second sewing grooves 110, and each strip panel 30 is placed corresponding to one second sewing groove 110, or the number of the strip panels 30 placed on one middle plate 11 may be less than the number of the second sewing grooves 110, and at least one second sewing groove 110 has no strip panel 30 placed corresponding thereto.

Referring again to fig. 3 and 4, in some embodiments, the second slot 110 has a first side 1101 and a second side 1102 along the width direction thereof, the middle plate 11 may be provided with a position-limiting component 13 corresponding to the first side 1101 and/or the second side 1102, and the position-limiting component 13 is spaced apart from the second slot 110.
