Abstract
A web of material is drawn by the machine from a removable supply roll over a first self-centering pulley, across a flat reviewing surface, over a second set of self-centering pulleys arranged in a figure S fashion, and is wound on a removable takeup shaft. Cutting means are provided for severing the portion of the web wound on the takeup shaft from the remainder of the web, and motor driven means are provided for selectively driving either the takeup shaft forwardly or the supply roll rearwardly in order to collate different web segments on one or more takeup shafts.
