Abstract of the Disclosure This invention provides a printing and die- cutting apparatus which operates on an elongated, continuous supporting web that has releasably adhered to its upper side a label-forming layer that is severed by the die-cutting into a plurality of labels and an integral ladder which requires stripping from the web before the latter is formed into a roll. The die-cutting portion of the apparatus includes an offsetting pair of parallel rollers mounted on a pivotal sub-frame adapted to be fixed in an angulated position with respect to the direction of web movement, with the web being strung between the pair of parallel rollers, such that the web emerges from the parallel rollers in the same general direction as it had upstream of the rollers, but offset both vertically and horizontally with respect to the original position. A further pair of offsetting rollers on another pivotal sub-frame is provided downstream, to bring the web back up into the original direction and in exact alignment with its original condition. A take-off roller for the ladder is positioned downstream of the first off-setting pair and mounted for free rotation with its axis transverse to web movement, the take-off roller being positioned to touch the plane of web movement from above, and the ladder is Adapted to extend out to the take-off roller and then around its periphery on the downstream side, subsequently to be wound up on a wind-up roll or mandrel for the ladder.
