And two rolls of cloth can be sewn through the cloth receiving machine, so that the problem that the feeding frame 20 uses manual feeding is avoided, and the cloth processing efficiency is improved. And the cloth is folded and sewn through the sewing mechanism 10, so that the edge of the cloth is prevented from running or breaking, and the attractiveness of the cloth is improved. After sewing, the cloth is stored by the magazine 80 and fed into the cloth cutting mechanism 90, where the cloth is cut. The broken surface condition can appear on the cloth surface sometimes, detects broken surface through quality detector 110 to cut out broken surface part through fabric cutting mechanism 90, need not the later process of manual detection screening qualified cloth. Because the sewing cloth is continuously conveyed, and the cutting cloth is intermittently conveyed, the two modes of conveying the cloth can be compatible through the material storage rack 80, and the cloth processing efficiency is improved. Meanwhile, the control center 40 is used for monitoring in the whole process, and manual control is also used, so that the safety and fluency of the operation of the cloth sewing and cutting equipment can be ensured.
