ABSTRACT:
In a winding wound in a figure-8 configuration, such as a universal winding which is known in the textile industry, the endforms of a spindle on which the winding is wound each respectively include openings enabling the projection therethrough of collapsing members such that the ends of the winding may be compressed to a substantially flat plane with the innermost winding. The mandrel is formed in two movable sections such that the two sections collapse towards one another with application of the compression force applied to each of the endforms.
