Background technique

In daily life, we often see sleeves on the sides of some clothes and a number of decorative strips parallel to each other on the outer side of the trousers. These decorative strips make the garment look more dynamic and beautiful. These decorative strips are sewn through multiple trims. The equipment is sewn. The current multi-sew sewing machine has a multi-needle sewing machine, a corresponding decorative strip feeding device and a tug mechanism. When sewing a multi-strip, the fabric that needs to be sewn is manually fed into the multi-needle sewing machine, and the plurality of decorative strips to be sewn are fed to the multi-needle sewing machine by the corresponding bead feeding device, and the multi-needle is used. The sewing machine sews a plurality of decorative strips onto the upper side of the corresponding fabric, and then pulls out the fabric of the sewn decorative strip by the corresponding tug mechanism. In the existing market, the multi-strip sewing equipment with the tug mechanism basically adopts the method of the upper tug and the lower tug, and when the fabric that needs to be sewn is soft or elastic, it will The decorative strip and the cloth movement are not synchronized, the decorative strip on the upper side of the fabric is normally driven by the upper tug, and the fabric on the lower tug is passively dragged to cause stretching, and the fabric shrinks after the sewing is completed, causing wrinkles, which seriously affects The quality of processing.
