product description

1. Large LCD operation screen with needle selection box, displaying more operation buttons on the screen, simple and elegant, real-time display of sewing process, multiple sewing pattern settings stored and retrieved for use at any time. 2. The stitching of the elastic ultra-thin fabric is smoother and more aesthetically pleasing, and the feeding of thick materials is smoother. 3. According to the different diagonal and twisting directions of the fabric and the rolled edges, the control system is set to achieve (deficit/synchronization/surplus) feeding of the upper feeding, and the arc sewing naturally transitions, achieving smooth and non twisting sewing of the arc bottom hem, and meeting the requirement of no scalding in the product. 4. The servo stepper motor is used to control the capacity of each section, which can automatically remember the number of needles and differential force or manually program and store 20 patterns. One hem arc can be set up to 15 sections, divided into time sections, and the differential force can be automatically adjusted or manually switched to meet all hem process requirements. 5. Activating the left knee rest button device does not take up manual operation time. Starting it one time at the seam control point can automatically switch to the next stage of differential force, which can better complete the entire roll and hem process, efficient and convenient
