ABSTRACT OF THE DISCLOSURE A device for widthwise control of web material, comprises bar structure having resiliently bendable beam means for effecting a primary bowed adjustment. A set of side-by-side independent but cooperative wrap area members are carried by the beam means and are adapted to be in- dividually selectively adjustable relative to the beam means to effect secondary adjustments incrementally at any of the members, without altering the primary bow relation, for correctionally compensating for uneven tension in any part of the web material, such as may be caused by web thickness, bulk or length.
