US 2022/0063954 A1 · YARN CARRIER TUBES

Abstract

The present disclosure is directed to a reusable yarn carrier tube around which yarn may be wound at high speeds (e.g., within winding machines). The yarn carrier tube may include a pick-up groove having structural features configured to better snag yarn to initiate winding of the yarn around the cylindrical body of the yarn carrier tube. The structural features may include an adaptable snagging feature that is adaptable to many different yarn types (e.g., diameter, denier, texture, material). The structural features may include projections (e.g., teeth) with incremental narrowing therebetween in the direction opposite to the rotational winding direction. The teeth may increase in sharpness (e.g., decreasing radii of curvature) as the yarn moves further into the pick-up groove.

Dependent claims

A reusable yarn carrier tube for winding yarns of various thicknesses thereon at high speeds as the carrier tube is rotated in a rotational winding direction, the carrier tube comprising:

a circumferential wall;
and
a pick-up groove formed through and extending along the azimuthal direction of the circumferential wall, circumscribed by a sidewall, wherein the pick-up groove comprises:
a plurality of teeth projecting from the sidewall of the pick-up groove toward a central azimuthal axis of the pick-up groove,
wherein the distance between the teeth, as measured across the pick-up groove in the longitudinal direction of the circumferential wall, decreases in a direction opposite to the rotational winding direction.
