Abstract
Apparatus for curling yarn or the like including a member having a hole forming a crimper chamber, a pair of feeder rollers for feeding said yarn through an end of said chamber for crimping therein, and devices for removing the crimped yarn under tension by the other end of said chamber, characterized by a member that rests against the mass of yarn in said chamber and moves to accommodate changes in the amount of yarn contained therein, and a central device acted upon by the movement of said member to vary the slip of said feeder rollers or of said device that pulls the yarn so as to maintain a substantially constant amount of yarn in said chamber.
