Method and apparatus for axial feed of ribbon material

摘要

A method of controlling twisting in ribbon material fed from a coil of ribbon material into a processing machine. The coil has a central axis perpendicular to a plane of the coil. The method includes pulling ribbon material from the coil in a direction having a twist-promoting axial component relative to the plane of the coil and continuously rotating the coil during the pulling step at a rotational speed greater than zero so that a number of twists in the unwound ribbon is maintained below a predetermined number.
