ABSTRACT:
Apparatus for aligning an elongate web with respect to a predetermined path of travel. The web is supplied from a supply roll formed by the web being wound around an inner web layer and having an outer web layer. The apparatus includes a frame, and an axle assembly on the frame adapted to hold the supply roll for rotation about an axis to afford unwinding of the web from the supply roll, and adapted for axial movement of the supply roll. An alignment device is provided comprising web-guiding rollers mounted on the frame and generally rigid in the direction parallel to the axis of the rotatable-holding means. The web-guiding rollers guide the opposite edges of the outer web layer of the web laterally with respect to the longitudinal direction of the web, with the axle assembly affording translation of the supply roll to accommodate telescoped or non-uniformly wound supply rolls, thereby to maintain alignment of the outer web layer with respect to the predetermined path of travel.
