ABSTRACT:
High-speed cross-winding apparatus with two traverse motion devices for winding elongated materials, especially continuous filaments, into packages and embodying a reciprocable thread guide as a first traversing device, and a second traversing device in the form of a roller with spiral, thread-guiding grooves, the first and second traverse motion devices being driven synchronously, and a drive roller for driving the package being driven independently thereof. The grooves of the latter traverse roller have variable depth for winding tension uniformity, and may also temporarily accelerate stroke velocity above the stroke velocity of the first traverse device immediately before and/or after stroke reversal. The groove depth increases from the middle of the roller to a maximum depth preceding the stroke reversal point and then either (a) immediately and continuously decreases in depth or (b) immediately decreases, then increases and then again decreases in depth.
