摘要

An apparatus for advancing limp material such as cloth for overedge stitching. The apparatus has a generally L-shaped arm which is designed to be pivotable in the lateral and upward directions relative to a surface of a working table of a sewing machine. The L-shaped arm has at least a single rotary element for advancing the cloth, the rotary element being driven through a driving pulley and an endless belt. The apparatus has devices for locking the lateral and upward movement against a resilient force of the endless belt.
