Abstract
Apparatus and method for winding a continuous strand formed from an attenuable material is disclosed. An end face of a winding collet includes strand-engaging elements spaced about the periphery of the end face of the collet that engage the strand as it is brought against the face of the collet. There are at least three strand-engaging elements on the face of the collet. The strand is conducted from the strand-engaging elements to the starting drum and is wound on the collet until it reaches operating speed. When the winding collet is at its operating speed, the strand is urged onto a winding sleeve to form the winding.
