ABSTRACT:
An apparatus and method for creating an overlock or 504 stitch wherein the excess thread chain (65) extending from the sewing machine needles (19) and the hollow chaining (32) to the previously sewn garment part (60) is stretched and is cut by thread chain cutter (70) to create a leading thread chain of predetermined length extending form the sewing machine needle and the hollow chaining tongue. When cut, the thread chain recoils toward the hollow chaining tongue, and a stream of air draws the free end of the thread chain into the hollow chaining tongue. When the next work piece is moved through the sewing area, the thread chain in the hollow chaining tongue is attached to the work piece and is progressively drawn out of the hollow chaining tongue and oversewn in the overlock stitch.
