DEFINITION

Classification: 242/479.7

Having progression roller engaging package periphery:

(under subclass 479.6) Subject matter in which the traverse limits are determined by the position of a moveable roller and in which the roller (1) is engageable with accumulating material on the take-up when the radius of the material reaches a certain point and (2) is shifted along the take-up due to contact with the accumulating material thereby shifting the limits of the traverse stroke.

(1) Note. The progression roller acts as a sensor of the location of current end of the material package being formed. Typically, the roller is threaded to a stationary threaded shaft or fixed to a rotatable threaded shaft mounted in a threaded support. The shaft is parallel to the axis of the take-up. The roller is maintained at a fixed distance from the axis of the take-up. When the package radius increases to contact the roller, the roller rotates and shifts axially of the take-up until it no longer contacts the package, thus following the end of the finished portion of the package.
