Description

Technical Field

[0001] The invention relates to cloth edge locking and binding, and in particular to a method and mechanical equipment for fully automatically processing the four edges of cloth. Background Art

[0002] When hemming and binding fabric of infinite length, the sides of the fabric are hemmed with a positive locking machine head on one side and a reverse locking machine head on the other side. The ends of the fabric are pulled apart and separated by a certain distance using a mobile device. Two hemming machines (edge ​​binding machines, sewing machines) are installed at the cut position, and the two hemming machines (edge ​​binding machines, sewing machines) sew the two cut edges respectively. Since reverse locking machine heads are expensive and can only hem thin fabrics but not thick fabrics, using reverse locking machine heads to hem the sides of the fabric is costly and has low adaptability. The ends of the fabric need to be pulled apart before they can be hemmed, and then pulled back after hemming is completed, making the process cumbersome. Summary of the Invention
