A canister-yarn tensioning assembly is adapted for controlling tension in a running yarn drawn from a yarn supply package located within an open-top canister. The canister-yarn tensioning assembly includes a cylindrical adapter configured to reside at a mouth of the open-top canister. The adapter defines an unobstructed package transfer space sufficient to allow the yarn supply package to be manually lowered through the adapter and into the canister. A pivoted support arm is carried by the adapter, and configured to pivot at a connection point located on a peripheral flange of the adapter. One or more yarn tensioners are carried by the pivoted support arm, and are movable between an operative position within the package transfer space and an inoperative package-replacement position outside of the package transfer space.

Yarn tensioner, textile machine, and method for tensioning a continuously running yarn
A yarn tensioner is adapted for adjusting tension in a running yarn. The yarn tensioner has a base, an adjustable pin rack, a fixed pin rack, and a fastener assembly. The adjustable pin rack is carried by the base and incorporates a first plurality of spaced apart parallel friction pins. The fixed pin rack is carried by the base and incorporates a second plurality of spaced apart parallel friction pins residing alternately between the friction pins of the adjustable pin rack. The running yarn travels across the yarn tensioner by snaking over and under adjacent parallel friction pins of the adjustable pin rack and the fixed pin rack. The fastener assembly attaches the adjustable pin rack to the base, such that the adjustable pin rack is movable relative to the fixed pin rack, thereby controlling frictional drag on the running yarn.

A yarn tensioner is designed for adjusting tension in a running yarn. The yarn tensioner includes a rotatable tension wheel having opposing yarn-contacting surfaces formed along an annular region thereof and configured to frictionally contact opposite sides of the running yarn such that the running yarn causes rotational movement of the tension wheel. An elongated wheel shaft is directly affixed to the tension wheel. A tension adjustment assembly frictionally contacts the wheel shaft, and creates select rotation resistance between adjacent parts of the assembly and the wheel shaft such that rotation of the tension wheel is adjustably frictionally controlled, thereby adjusting tension in the running yarn.

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.

An overfeed roller assembly for use on a rotating drive shaft of a textile machine is adapted for adjusting downstream tension in a continuous moving length of yarn. The overfeed roller assembly comprises a base assembly designed for mounting on the drive shaft, and an annular yarn tension adjuster carried by the base assembly. The tension adjuster comprises opposing closely spaced yarn-contacting walls. The yarn- contacting walls define a shallow generally serpentine depression in the tension adjuster adapted for receiving the continuous moving length of yarn. Yarn tension downstream of the roller assembly is thereby reduced as the moving yarn meanders through the tension adjuster in frictional contact with the yarn-contacting walls of the serpentine depression.

A yarn tension control device controls tension in a running yarn. The tension control device includes a housing having a yarn guiding inlet for receiving running yarn at an unwinding tension from a yarn supply source, and a yarn guiding outlet for guiding running yarn exiting the housing at a delivery tension. First and second opposing yarn engaging surfaces are disposed between the inlet and the outlet, and are adapted to frictionally engage opposite sides of the running yarn along a path of yarn travel through the housing. The first and second yarn engaging surfaces define a respective plurality of sequentially spaced friction rolls. A biasing assembly resiliently urges the first and second yarn engaging surfaces together. The opposing friction rolls cooperate to form a number of sequentially spaced nip points adapted to adjust yarn delivery tension in response to stress variations in running yarn entering the housing.
A textile stuffer box includes a housing having an entrance and an exit, and including cooperating chamber-forming surfaces defining an internal crimping chamber for receiving and accumulating a length of yarn. An adjustable sliding gate defines at least one of the chamber-forming surfaces adjacent the exit of the housing. A set screw releasably locks a position of the gate to selectively enlarge and narrow the exit of the housing, such that selective adjustment of the gate operates to control axial compression of yarn accumulating inside of the crimping chamber.
