Abstract
The present invention includes a high-speed, relatively low-inertia, gearless, synchronized puller attachment for cooperative use with fabric sewing, handling and fastening machines, or the like. In the case of sewing machine applications, uniform stitch repeatability is achieved through the provision of top and bottom pulling rollers that are each positively driven at high speeds through anti-reversing means positioned relatively near the needle side of the sewing machine. Little, if any, output inertia is present, thereby permitting high-speed indexing without braking means being necessary. A novel adjustable linkage provides a reliable and substantially equal angular displacement of both pulling rollers in a harmonic motion synchronized both as between said pulling rollers as well as the sewing machine feed.
