For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] See also Figures 1 to 5 The utility model discloses an auxiliary device for hem-covering, comprising a first auxiliary component 1 and a second auxiliary component 2;

[0040] The first auxiliary component 1 includes a first bottom plate 11 and a column 12 for simulating gestures to bend fabric, wherein the column 12 is erected on the first bottom plate 11 and is integrally formed with the first bottom plate 11;

[0041] Specifically, before sewing the hem, it is necessary to manually adjust the fabric through gestures, wherein first the width of the folded surface of the hem must be determined, and a column 12 with the same folded surface width and the same height can be used to position the folded edge of the hem of the fabric to replace manual fingers to perform the operation. The replaced finger can be the index finger, middle finger or ring finger, specifically corresponding to the manual gesture habits, as long as the folded edge position of the fabric before the hem can be determined.

[0042] Furthermore, the integral molding of the first base plate 11 and the column 12 can increase the stability of the first auxiliary component 1 and prevent the column 12 from loosening, thereby affecting the positioning of the column 12 on the hem of the fabric cover. The first base plate 11 and the column 12 can also be detachably connected to replace the columns 12 of different heights. The one-piece molding method is a preferred method, which is convenient to process and produce and has high stability.

[0043] Furthermore, when in use, the worker can press the first base plate 11 on the work station with the palm of his hand, so as to fix the first auxiliary part 11. Especially when using a sewing machine, it only needs to be placed on the sewing position of the sewing machine for use, which has high flexibility and practicality.

[0044] The second auxiliary member 2 includes a second bottom plate 21, a folding surface 22 extending from the second bottom plate 21 for simulating a gesture to fold the fabric, and a pull tube portion 23, wherein the pull tube portion 23 is formed by a pull tube top wall 231 and the end of the folding surface 22 to form a pull tube groove 232 for limiting the stitches of the fabric;

[0045] Specifically, the folding surface 22 is an arc-shaped structural surface with a curved surface formed by folding the second bottom plate 21 in a direction perpendicular to the second bottom plate 21 under the initial plane shape. The main function of the folding surface 22 is that after the pillar 12 positions the folded edge of the fabric, the folded surface of the fabric will abut the folding surface 22, and the curved surface of the folding surface 22 has the function of simulating manual gestures to guide the fabric to fold in half, and the fabric can be folded in half before entering the pull-cylinder groove 232. The main function of the pull-cylinder groove 232 is to maintain the folded state formed by the hem of the fabric and transport it from the outlet of the pull-cylinder groove 232 to the seam position under the sewing machine needle for sewing, which can replace the role of the hem gesture in manual experience. Even workers who have not yet learned the hem-making process can achieve the hem-making effect of skilled workers, and the process requirements of the hem-making machine can be met. It can help solve the proficiency problem of hem-making workers and shorten the manual training cycle to meet the production needs of the hem.

[0046] The second auxiliary member 2 is disposed on the first auxiliary member 1 , and the column 12 is close to the inflected surface 22 .

[0047] Specifically, the upright post 12 being close to the folding surface 22 helps the upright post 12 to further guide the fabric to fold in half through the folding surface 22 before the initial folding state of the fabric changes after positioning the folded edge of the fabric, thereby achieving the same effect as a manual gesture.

[0048] As a preferred embodiment, at least one mounting hole 13 is provided on the first base plate 11 of the first auxiliary component 1, and at least one positioning hole 24 is provided on the second base plate 21 of the second auxiliary component 2. The first auxiliary component 1 is installed on the sewing station by bolt connection through the mounting hole 13.

[0049] Specifically, the mounting hole 13 is configured as a long through groove, so that the position of the first auxiliary component 1 can be adjusted. In addition to the method in which the worker presses the first auxiliary component 1 with his palm, the first auxiliary component 1 can also be flexibly installed next to the seam by passing bolts through the mounting hole 13, thereby reducing the workload of the workers. It is easy to know that in addition to the bolt connection method, the first auxiliary component 1 can also be installed by a latch method. The bolt connection installation method is only used as a preferred implementation method. The installation method of the first auxiliary component 1 is not limited in this application, that is, the worker fixes the first auxiliary component 1 with his palm or other methods that can install the first auxiliary component 1 in the seam can all play the role of the first auxiliary component 1.

[0050] As a preferred embodiment, the second auxiliary component 2 is positioned and installed above the first auxiliary component 1 by means of bolt connection through the matching of the positioning hole 24 and the mounting hole 13 .

[0051] Specifically, bolt connection is a preferred method, which allows the second auxiliary component 2 to rotate around the bolt as the axis on the first auxiliary component 1 to adjust its position. The present application does not limit the installation method of the second auxiliary component 2. When using the auxiliary device, workers can position the auxiliary device by pressing the first auxiliary component 1 with their left hand / right hand and pressing the second auxiliary component 2 with their right hand / left hand. They can also use pins to install the first auxiliary component 1 and the second auxiliary component 2 in the seam.

[0052] As a preferred embodiment, the connection between the inflected surface 22 and the second bottom plate 21 is a smooth curved surface formed by inflecting the second bottom plate 21, and the inflected surface 22 as the bottom surface of the pull tube groove 232 is a smooth plane.

[0053] As a preferred embodiment, a hook surface 221 is provided on the smooth plane of the inflected surface 22 for forming a stop to prevent the stopper from being exposed, and the hook surface 221 is formed by extending from the inflected surface 22 to the gap between the pull tube top wall 231 and the inflected surface 22.

[0054] Specifically, the stop is the position where the fabric fold is folded back and sewn on the fabric, that is, the connection between the fold and the fabric, and the function of the stop is to prevent the connection between the fold and the fabric from turning outward and causing the stop to be unable to close. Therefore, the hook surface 221 is set to be an arc surface bent into the pull tube groove 232, ensuring that the sewing seam of the fabric and the fold at the stop can be completely closed, thereby ensuring the product quality of the hem clothing.

[0055] As a preferred embodiment, the column 12 and the pull-tube groove 232 are located on the same horizontal line, and the smooth curved surface of the folded surface 22 is inclined to the horizontal line. The column 12 and the pull-tube groove 232 are located on the same horizontal line to ensure that the fabric will not be pulled and cause damage to the fabric, and the inclined setting of the smooth curved surface can facilitate the fabric to slide over on the folded surface 22, tighten the fabric and the folded surface of the fabric, and facilitate the subsequent pull-tube groove 232 to shape the hem fabric.

[0056] As a preferred embodiment, the height of the column 12 is the same as the corresponding height of the hem of the jacket, and the height of the column 12 ranges from 1 cm to 3 cm.

[0057] As a preferred embodiment, the entrance width of the pull-tube groove 232 is greater than the exit width of the pull-tube groove 232 , and the pull-tube groove 232 is a gradually narrowing design structure, which can guide the fabric to tighten and improve the product quality.

[0058] The utility model simulates the hand gesture of manually hemming the fabric through the first auxiliary part and the second auxiliary part, thereby acting on the fabric to complete the hem-covering process, wherein the first auxiliary part fixes the hem height of the fabric through the column, provides a fulcrum for the fabric to fold the edge through the top of the column, thereby guiding the fabric to form a folded state, and the folded surface close to the column simulates the folding of the fabric by fingers with the assistance of the column, so that the fabric is folded in half before entering the draw tube groove, and the draw tube groove can keep the folded state in a fixed shape until the folded fabric is pushed from the outlet of the draw tube groove to under the machine needle of the seam position, thereby assisting manual work to complete the hem-covering process, can reduce the requirement for manual work on skilled experience, can quickly get started with the hem-covering process, shortens the training cycle of manual work, and can meet the production needs of the hem-covering on the premise of ensuring the quality of the hem-covering product, improve the production efficiency of the hem-covering, can be promoted in the production of garment workshops, and has high practical value.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
