Abstract

A textile stuffer box comprises a housing assembly having a yarn entrance and a yarn exit, and cooperating interior chamber-forming surfaces. The chamber-forming surfaces defines a multi-stage internal crimping chamber for receiving and accumulating a moving length of ply-twisted yarn between the entrance and exit of the housing assembly. The crimping chamber comprising an upstream fixed-volume stage and a downstream adjustable-volume stage. A weight-balanced gate selectively adjusts a volume of the downstream adjustable-volume stage of the crimping chamber, thereby controlling axial compression of yarn accumulating inside the upstream fixed-volume stage of the crimping chamber.

Dependent claims

A textile processing assembly for texturing and heatsetting a moving length of ply-twisted yarn, said textile processing assembly comprising:

(a) a pair of feed rolls adapted for engaging and moving the yarn downstream away from a supply creel;
(b) a textile stuffer box downstream of said feed rolls, and comprising:
(i) a housing assembly having a yarn entrance and a yarn exit, and comprising cooperating chamber-forming surfaces defining a multi-stage internal crimping chamber for receiving and accumulating the ply-twisted yarn between the entrance and exit of said housing assembly, said crimping chamber comprising an upstream fixed-volume stage and a downstream adjustable-volume stage;
(ii) means for selectively adjusting a volume of the downstream adjustable-volume stage of said crimping chamber, thereby controlling axial compression of yarn accumulating inside the upstream fixed-volume stage of said crimping chamber;
(c) a climate chamber downstream of said stuffer box, and adapted for heat-setting the ply-twisted yarn;
(d) means for conveying the yarn downstream from said stuffer box and through said climate chamber;
and
(e) a take-up winder downstream of said climate chamber for collecting the processed yarn.
