Abstract:
A process for winding an elastomeric fiber (2), comprising the steps of:(A) rotating a tubecore in contact with a roll (3); (B) winding the fiber onto the tubecore so that the contact roll exerts an initial force no greater than about 10 kg against the fiber on the tubecore and a package (1) begins to be formed; (C) reducing the force a first time to about 25-60% of the initial force during the first 30% of winding time; (D) holding the force substantially constant until the final 30% of winding time; and (E) reducing the force a second time to about a final force that is 10-35 k of the initial force, wherein the final force is no less than about 1 kg and the package size is at least 4 kg.
