High speed sewing machine ruffler

摘要

A high speed sewing machine (15) ruffler (16) where the sewing machine output (26, 27) drives a belt (28) which operates a pair of shafts (24, 25) to move a ruffler pusher blade (46) at high speeds. The sewing machine output belt causes shaft (24) to oscillate by a drive lever (35), and causes shaft (25) to rotate by means of drive pulley (29). The oscillating shaft (24) rocks ruffler arm (45) to cause pusher blade (46) to move to and fro, while rotating shaft (25) causes an eccentrically mounted lift link (47), through connector (51), to lift the pusher blade from the material (53) upon the withdrawal stroke and to lower the pusher blade upon the feed stroke.
