Fiber crimping apparatus with movable crimping member

摘要

A fiber crimping apparatus includes a relatively large diameter ring roller and an inscribed roller in contact with an inner surface of the ring roller. The two rollers are rotatable in the same direction at the same velocity and defined between contacting surfaces thereof a nip zone through which are to be fed bundles of fibers that are to be crimped therebetween. Each roller has thereon a respective side ring that is rotatable with the respective roller. The two rollers and two rings therefore define therebetween, at a downstream side of the nip zone, a stuffing box into which the bundles of fibers pass from the nip zone. A crimping resisting device is installed at a downstream side of the stuffing box and includes a movable member that is mounted to be movable in a widthwise direction of the stuffing box and of the bundles of fibers passing therethrough.
