When it is necessary to curl one end of the sofa body 26, the clamping block 15 can be driven to move toward the side of the fixing frame 24 by pulling the pull rod 20. Because a section of the sofa body 26 is not clamped, when the sofa body 26 moves toward the fixing frame 24, the unclamped area will curl. By passing one end of the limit rod 23 through the mounting holes in sequence, 21 and the limiting hole 22 can keep the pull rod 20 and the placement frame 12 in a fixed state, and can avoid the slight deviation of the sofa body 26 caused by the vibration during the operation of the machine. The threaded motor 2 drives the sewing needle 10 to move horizontally. When adjusting the sewing position, the ruler 14 fixedly installed on one side of the side plate 13 can be used as a reference for adjustment. After the adjustment is completed, the sewing needle 10 is driven to move downward by starting the cylinder 5, and then the sewing needle 10 will contact the curled sofa body 26. Then, the sewing host 9 can drive the sewing needle 10 to the curled sofa body The body 26 is sewn, and the moving block 8 is driven to move by the operation of the electric push rod 7, and then the sewing needle 10 can realize mobile sewing. Because the bottom side of the sewing main machine 9 is fixedly installed with an auxiliary wheel 11, and the auxiliary wheel 11 and the sewing needle 10 are on the same horizontal line, when the sewing needle 10 moves to sew, the auxiliary wheel 11 can press the curling area of ​​the sofa body 26, and then follow the sewing needle 10 to roll synchronously, thereby ensuring that the curling of the sofa body 26 is fixed during sewing and avoiding deviation. After sewing is completed, the curling process of the lower end of the sofa body 26 can be carried out.
