Patent ID: 7185406

Claim:
An apparatus for texturing yarn, comprising: (a) a yarn feeding assembly for delivering a yarn from a supply; (b) a first yarn treatment chamber downstream from the yarn feeding assembly for receiving the yarn from the yarn feeding assembly, and comprising: (i) a first yarn compression zone for applying a first compression force to the yarn; and (ii) a second yarn compression zone, comprising first and second opposed, rotationally-mounted, non-intersecting, non-contacting compression rollers for receiving the yarn from the first yarn compression zone, the first and second compression rollers each having a plurality of spaced recesses formed in respective outer surfaces, a one of the spaced recesses of the first roller cooperating with a radially-aligned recess of the second roller during rotation to collectively form successive yarn compression pockets that compress the yarn with a second compression force while simultaneously moving the yarn downstream; (c) a second yarn treatment chamber for receiving the yarn from the first and second compression rollers and applying a further treatment thereto; and (d) a discharge assembly for allowing controlled, predetermined removal of the treated yarn from the second treatment chamber for downstream processing.
