Method and apparatus for winding covered yarn

Abstract

Disclosed is a method and apparatus for winding covered yarn, namely non-elastic yarn twisted about a strand of elastomeric yarn, on a core to form a take-up package so that the wound covered yarn can be drawn (unwound) from the package without hanging up on itself or puckering. Winding of the take-up package is done on the same machine that performs the twisting operation and involves the following apparatus and method steps: providing a hollow core on which the covered yarn is to be wound, disposing a shaft assembly inside of the core, the shaft assembly having (a) a shaft, (b) first and second spaced apart disc means axially affixed to the shaft (one of the discs having a diameter larger than the other if the core is cone shaped), (c) a mass axially disposed on the shaft, lying between its midpoint and one of its free ends; providing covered yarn composed of an elastomeric filament about which at least one non-elastomeric filament is wound or twisted; and, then winding the covered yarn on the outermost surface of the core by rotating the core and shaft assembly.
