ABSTRACT:
The present invention relates to a variable compressibility layer in rollers or flat pulleys. The present invention provides a smooth-surface roller that will "spread" a web being conveyed by a roller, or urge flattening and prevention of wrinkles in the web. It will also assist in the centering of the web being conveyed on web-handling equipment. If a roller is small, it may be used as a flat pulley, wherein the present invention causes a belt to track in the center of the pulley.
