Abstract
A method and combination for eliminating slack in one or more of a plurality of strands of web material being wound into coils on a take-up drum, where the strands have different thicknesses, include connecting a portion of each strand to the drum so that rotation of the drum will cause the strands simultaneously to wind onto the drum. The strands are wound onto the drum and a portion of each strand is connected to a previously wound portion of the same strand for forming a plurality of fixed diameter loops about the drum, the portion of each strand adjacent to the drum substantially conforming in size and shape to the outer surface of the drum. The portion of each strand connected to the drum is disconnected and the outer diameter of the drum is reduced an amount sufficient to cause the loops to slip relative to the drum when the drum is rotated and a predetermined tension is reached in the strands, the frictional force between the strands and drum causing the loops to rotate with the drum until said predetermined tension is reached.
