Apparatus (10) for aligning an elongate web (12) with respect to a predetermined path of travel. The web (12) is supplied from a supply roll (20), and the apparatus (10) includes an axle assembly (36) adapted to hold the supply roll (20) for axial movement and rotation. A web guide (46, 48, 50) is provided for guiding the opposite edges (16, 18) of the outer web layer (24) of the supply roll (20) laterally with respect to the longitudinal direction of the web (12), with the axle assembly (36) affording translation of the supply roll (20) to accommodate telescoped or non-uniformly wound supply rolls (20), thereby to maintain alignment of the outer web layer (24) with respect to the predetermined path of travel. |
