Abstract:

A compensating roller for expanding and contracting flexible sheet materials having a curved axle which can be set in any desired plane about a straight axis common to its end support brackets. The curved axle is a three-piece axle having end sections which also are adjustable to both raise and lower and/or to rotate them with respect to the center section of the curved axle whereby the expansion or contraction of the opposite side ends of the web can be more closely controlled to virtually eliminate wrinkling of the side edges.
