ABSTRACT:
A mechanism is disclosed for driving a puller wheel to assist in feeding cloth material through a sewing machine. The material passes between a puller wheel and an idler wheel after having been sewn by a reciprocating needle. The driven puller wheel assists the standard feed dogs in feeding the material past the needle. The invention discloses a positive drive mechanism having a variable speed gearbox driven by the sewing machine motor and drivingly connected to the puller wheel. The distance between puller wheel and idler wheel is variable to accommodate any thickness of material and still provide a positive feed.
