OVERFEED ROLLER ASSEMBLY, TEXTILE MACHINE, AND METHOD OF ADJUSTING TENSION IN A RUNNING YARN

American Linc, LLC, Gast...

1. An overfeed roller assembly for use on a rotating drive shaft of a textile machine and adapted for adjusting downstream
tension in a continuous moving length of yarn, said roller assembly comprising:
a base assembly designed for mounting on the drive shaft;
a plurality of arcuate yarn tension adjusters carried by said base assembly, and wherein said base assembly comprises a mounting
sleeve adapted for being affixed to the drive shaft, and first and second opposing end caps carried by the mounting sleeve
and cooperating to secure said arcuate tension adjusters therebetween, each tension adjuster comprising opposing closely spaced
yarn-contacting surfaces defining a pathway along said tension adjuster adapted for receiving the continuous moving length
of yarn, whereby yarn tension downstream of said roller assembly is reduced as the moving yarn passes through said arcuate
tension adjusters in frictional contact with the yarn-contacting surfaces of the pathway.

YARN CREEL ASSEMBLY ADAPTED FOR CARRYING MULTIPLE INTERCONNECTED YARN PACKAGES IN A PLURALITY OF VERTICALLY SPACED PACKAGE STATIONS

American Linc, LLC, Gast...

1. A yarn creel assembly, comprising:
a vertical frame;
a plurality of vertically arranged package stations, each package station comprising:
i. an elongated package holder having a proximal end attached to said vertical frame and a distal end adapted for receiving
and carrying a yarn package, whereby a tail end of one yarn package in a first package station is attached to a head end of
another yarn package located in a second package station;

ii. a substantially horizontal planar station divider located between vertically adjacent package stations; and
iii. a vertical wall adjacent said station divider and spaced apart from the distal end of said package holder, said vertical
wall defining an arcuate yarn guide adapted for guiding a moving end of yarn drawn from an emptying yarn package in the first
package station and transitioning to a full yarn package in the second package station, and wherein said arcuate yarn guide
comprises a continuous slot having first and second end points, and wherein the first endpoint of said arcuate yarn guide
is located forward of and below said package holder, and wherein the second end point is located rearward of and above said
first end point.

TEXTILE STUFFER BOX AND METHOD FOR TEXTURING YARN

American Linc, LLC, Gast...

1. 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, wherein said means for selectively adjusting a volume of the downstream adjustable-volume stage of said crimping chamber comprises an elongated chamber gate extending linearly between opposing terminal end edges and a removable gate weight, said chamber gate being pivotably mounted to said housing assembly at an intermediate fulcrum point of said chamber gate, and said fulcrum point dividing said chamber gate to form an inside-the-chamber first end defining at least one of said chamber-forming surfaces adjacent the yarn exit of said housing assembly, and an outside-the-chamber second end comprising a removable gate weight, and said first and second ends of said chamber gate being integrally formed together as a single elongated structure, and said gate weight being selectively positioned along the outside-the-chamber second end of said chamber gate to adjustably increase and decrease a resistance exerted by said chamber gate, whereby selective adjustment of the gate resistance operates to control axial compression of yarn accumulating inside 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.
