Abstract
Process comprises generating a basically rectangular or square relative winding movement between the core ring and the braked feed spool. Pref. the spool executes the movement parallel to the axis of the core ring, while the core ring executes the movement radial to itself. The prod. has no excessive variations in distance from core to spool, necessitating intermittent rewinding of spool at certain stages, and no twist on the wound cord.
