The tube 32 is located at the edge above the first waist lilac tube 31, and the strip sticking tube 32 is detachably mounted on the workbench 1 through the second bracket 35, which is convenient for the strip sticking tube 32 to be installed, removed or replaced on the workbench 1. The second waist lilac tube 33 is located at the edge above the strip sticking tube 32, and the second waist lilac tube 33 is detachably mounted on the workbench 1 through the third bracket 36, which is convenient for the second waist lilac tube 33 to be installed, removed or replaced on the workbench. The distance between the discharge port of the first waist lilac tube 31, the strip sticking tube 32 and the second waist lilac tube 33 and the presser foot of the sewing machine 2 gradually decreases.

[0015] The method of making waist lining by using the present device is as follows: a first waist lining fabric is placed at the inlet of a first pull cylinder 31, and during the process of the first waist lining pull cylinder 31 feeding the first waist lining fabric, the first waist lining fabric can be folded and sent out from the outlet of the first waist lining pull cylinder 31, and at the same time, an anti-skid tape is sent into the inlet of a tape tape pull cylinder 32, and the tape tape pull cylinder 32 can send out the anti-skid tape from the outlet of the tape tape pull cylinder 32 and stick it on one side surface of the folded first waist lining fabric, and at the same time, a second waist lining fabric is sent into the inlet of a second waist lining pull cylinder 33. At the opening, the second waist lining pulling cylinder 33 can fold the second waist lining fabric in half and send it out from the outlet of the second waist lining pulling cylinder 33 to stick to the upper side of the anti-slip strip. After that, the stuck first waist lining fabric, anti-slip strip and second waist lining fabric are loosened to under the presser foot of the sewing machine 2, and the stuck first waist lining fabric, anti-slip strip and second waist lining fabric can be sewed by the needle of the sewing machine 2. After the sewn first waist lining fabric, anti-slip strip and second waist lining fabric are flattened and trimmed by the pressing component 4, the waist lining is completed. The device utilizes the coordinated use of the first waist lining pull tube 31, the strip pull tube 32 and the second waist lining pull tube 33 to complete the folding, laminating and sewing of the first waist lining fabric, the anti-slip strip and the second waist lining fabric at one time. The setting of this structure not only effectively reduces the production process of the waist lining, accelerates the production speed of the waist lining, and improves the production efficiency of the waist lining, but also reduces the operator's requirement for proficiency. The operator only needs to put the corresponding fabric into the pull tube to automatically complete the production of the waist lining. The degree of automation is relatively high. At the same time, the production quality of the waist lining can be effectively improved. The waist lining after production is uniform and of good quality. There is no rework phenomenon, and customer satisfaction is high.

[0016] Furthermore, the first waist lining pull tube 31 includes a first bottom plate 311 and a first top plate I312 and a second top plate II313 located above the first bottom plate 311. One side of the first top plate I312 and the second top plate II313 are connected to the first bottom plate 311 respectively through a first arc segment 314. An opening is left between the other sides of the first top plate I312 and the second top plate II313. The first top plate I312, the second top plate II313 and the first bottom plate 311 are integrally processed and manufactured. When the first waist lining fabric passes between the first bottom plate 311, the first top plate I312 and the second top plate II313, after being bent by the first arc segment 314, the two sides of the first waist lining fabric can be folded, thereby completing the folding and conveying of the first waist lining fabric.

[0017] Furthermore, the strip pull tube 32 includes a second bottom plate 321 and a second top plate 322 located on the upper side of the second bottom plate 321, the second top plate 322 and the second bottom plate 321 are connected on both sides by a second arc segment 323, the second bottom plate 321, the second top plate 322 and the second arc segment 323 are integrally processed and manufactured, and the internal space enclosed by the second bottom plate 321, the second arc segment 323 and the second top plate 322 is for the anti-slip strip to pass through, and when the anti-slip strip passes between the second bottom plate 321 and the second top plate 322, it can ensure the smooth transportation of the anti-slip strip.

[0018] Furthermore, the second waist lining pull tube 33 includes a third bottom plate 331 and a third top plate 332 located above the third bottom plate 331, one side of the third bottom plate 331 is connected to one side of the third top plate 332 through a third arc segment 333, the other side of the third bottom plate 331 extends to the other side of the third top plate 332, the third bottom plate 331, the third top plate 332 and the third arc segment 333 are integrally processed and manufactured, when the second waist lining fabric enters the entrance of the third top plate 332 and the third bottom plate 331, the second waist lining fabric can be folded and conveyed through the bending action of the third arc segment 333.

[0019] Furthermore, in order to ensure the continuous and stable transportation of the anti-skid strips, the anti-skid strips are basically in the form of a coil structure. A fixed disk 5 is installed on the workbench 1, and a rotating rod 6 is vertically rotatably installed at the center of the fixed disk 5. There are multiple strip pull cylinders 32, and multiple strip pull cylinders 32 are evenly arranged on the second bracket 35 between the sewing machine 2 and the fixed disk 5. When in use, the coil of the anti-skid strip is installed on the rotating rod 6, and the rotating rod 6 unwinds the anti-skid strip coil. The unwound anti-skid strip passes through multiple strip pull cylinders 32 in turn, so that the anti-skid strip can be transported evenly and stably. Preferably, a strip guide rack 7 is provided on the second bracket 35 near the fixed disk 5, and the strip guide rack 7 is configured as a continuous serpentine structure.
