ABSTRACT:
The present invention teaches a high-speed indexing system for use with any number of fabric-moving apparatus, a novel braking system for use within the indexing system, and a novel puller accessory. The high-speed adjustable indexing system is illustrated in connection with a sewing machine, as an example. In sewing machine applications, a synchronized intermittent advancement of fabric in unison with the movement of an associated feed dog is provided. Undesirable inertia-caused roller overshooting, heretofore treated with anti-reverse clutches and other approaches, is eliminated, thereby enabling high speed indexing at machine operating speeds conventionally unattainable in the art. An adjustable spring-biased braking arrangement is provided which may be preset for known machine operating speeds.
