Description

Technical Field

[0001] The utility model relates to the technical field of clothing sewing equipment, in particular to a rotary feeding and independent sewing workstation. Background Art

[0002] Traditionally, pocket patching is done by pressing a piece of cardboard the same size as the pocket onto the fabric to be sewn. After the edges are folded and ironed to set, the piece is then manually sewn onto the main fabric. This method requires skilled ironing technicians, resulting in inconsistent product quality and uneven seams. Furthermore, existing fully automatic cold-fold pocket patching machines use a certain distance between the cold-folded pocket opening and the main fabric before being pressed and dragged under the sewing machine. This process, combined with the friction of the lower plate, can cause problems, particularly with thin, smooth, and strong fabrics, such as misalignment, deformation, and delamination between the upper and lower layers, leading to substandard and fatigued products.
