Abstract
A winding process for an elastomeric fiber package using a contact roll that exerts variable pressure during the winding to create an elastomeric fiber package with a good package shape. The method including having a high initial force of the contact roll of less than 10 kg, reducing the force to about 25-60% of the initial force during the first 30% of winding time, then holding the force substantially constant until the final 30% of the winding time when the force is reduced to about a final force of 10-35% of the initial force. Wherein the final force is no less than about 1 kg and the package size is at least 4 kg.
