  • Synchronous drive system for automated textile drafting system
    Patent number: 5796220
    Abstract: An automated drafting system particularly suitable for drafting textile strands of sliver is provided. The automated drafting system includes a synchronous drive sliver drafting roller system utilizing toothed gears in the preferred embodiment operatively connecting a pair of drafting rollers with one of the rollers being directly driven by a motor to thereby cause identical rotation of both rollers. The automated drafting system also includes a system for securing and pressuring together upper and lower sliver drafting rollers wherein the lower roller of a pair of drafting rollers is preferably maintained in a fixed but rotational position while the upper roller of the pair is pressured towards the lower roller and controllably restricted as to both horizontal and vertical movement during the drafting process.
    Type: Grant
    Filed: July 19, 1996
    Date of Patent: August 18, 1998
    Assignee: North Carolina State University
    Inventors: Timothy G. Clapp, Jon P. Rust, Carlos Farrington, Dale Thomas Bowen
