An apparatus and method for accurately setting a cutting gap of a fiber cutting assembly of the type having a cutter reel with a plurality of radially spaced apart, cutting blades and a presser roll mounted adjacent to the cutter reel and having a peripheral surface positioned at a predetermined distance from the cutting edges of the cutting blades to define the cutting gap. The apparatus comprises a gauge member at one of the cutting blade positions which extends radially beyond the radial distance of the blades and corresponds to the desired cutting gap setting, and means for electrically sensing contact of the gauge member with the presser roll.

Apparatus and method for accurately setting the cutting gap of a fiber

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.
