ABSTRACT:
Two blade members are counter-rotated from a rest position to a cutting position in which radially directed cutting surfaces cooperate to snip a strip of material by a shearing action as the strip of material flows from a sewing machine or other processing machine. The blade members are reversible and are biased against each other to ensure positive cutting. A hinge-like linkage permits an offset between the blade members and power means to increase versatility. The cutting apparatus can include sensing means to permit automatic cutting of a completed workpiece from an excess of a strip of material which is sewn to the workpiece during the manufacture of a garment.
