Abstract
A yarn carrier especially for use with packages of pre-oriented yarn has a pair of grooves therein which accommodate extra thicknesses of yarn which accumulate at areas on the carrier where reversal of the yarn takes place. Engagement of these thicknesses by a winding roll does not result in faults in the yarn because the thicknesses are urged by the winding roll into the grooves.
Claims8
A tubular carrier for a textile yarn winding package, wherein the tubular carrier has a package winding area along its length and is used with a winding machine which includes a winding roll for tangential contact with the package, and wherein the winding roll has a start-up ring extending therearound generally in a plane normal to the axis of the winding roll, said ring having a diameter greater than the diameter of the roll, so that the outer surface of the ring extends beyond the outer surface of the roll, and being axially displaced from the package winding area, the winding machine further including a traversing mechanism for distributing yarn on the roll;
- the improvement comprising:
- a pair of circular grooves around the periphery of the carrier at the areas corresponding to reversals of the traversing mechanism, said grooves having a depth at least as great as the thickness of the start-up ring.
