Description

Technical Field

[0001] The utility model relates to the technical field of clothing sewing equipment, in particular to a hoisting bag folding device. Background Art

[0002] Traditionally, patch pockets are sewn by pressing pocket-sized cardboard onto the desired fabric piece, folding and ironing the edges to set the shape, and then manually sewing them onto the larger fabric piece.
