  • Patent number: 4642860
    Abstract: In the crimping of textile fibers, opposed rolls are rotated to force-feed the fibers through a nip defined by the rolls and into a stuffer box. A pair of cheek plates are pressed against the ends of the opposed rolls such that a front surface of each cheek plate engages ends of both rolls adjacent the nip to retain the fibers against lateral displacement from the nip. Atomized lubricating liquid is sprayed toward an inlet of the nip and against portions of the ends of the rolls approaching the nip, and against backsides of the cheek plates.
