STUFFER CRIMPER WITH DRIVEN CHOKE MEMBERS FOR PRESSURE CONTROL IN THE CRIMPING ZONE

摘要

A stuffer crimper fed with yarn from a pair of feed rolls having a chamber defining a crimping zone adjacent the feed rolls followed in succession by a heating zone and a cooling zone where the pressure on the yarn core within said crimping zone and the pressure on the core passing through the succeeding heating and cooling zones are independently controlled by roller means having core gripping surfacing projecting into said chamber at the juncture of said crimping and heating zones, said roller means being mounted and driven to rotate parallel to the axes of said feed rolls at a speed related to the speed of said feed rolls.
