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.
Claims10
A reviewing and collating machine for drawing a web of material along a predetermined path from a supply roll across a flat reviewing surface and winding it on a batching roll, comprising an upright frame, a supply roll shaft, means for rotatably and removably mounting the supply roll shaft on the upright frame at one end of the predetermined path, a substantially flat reviewing surface supported by the frame, a first self-centering web feed pulley rotatably mounted on the frame between the supply roll shaft and the reviewing surface along the predetermined path of travel of the web of material, a takeup shaft for supporting the batching roll, means for rotatably and removably mounting the takeup shaft on the frame at the other end of the predetermined path, a second self-centering pulley rotatably mounted on the frame between the reviewing surface and the takeup shaft along the predetermined path, means for selectively driving either the takeup shaft to draw the web of material in a forward direction along the predetermined path or the supply shaft to draw the web of material in the opposite direction along the predetermined path, and means for severing the batching roll from the remainder of the web of material.
