Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
204 words
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.
Claim 2
Dependent Claim
204 words
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.
Claim 3
Dependent Claim
27 words
A reviewing and collating machine as recited in claim 1 wherein the reviewing surface comprises a translucent panel and means are provided for backlighting the translucent panel.
Claim 4
Dependent Claim
42 words
A reviewing and collating machine as recited in claim 1 further comprising skew adjustment means for shifting the position of one end of the takeup shaft to change the angle at which the web of material is wound on the takeup shaft.
Claim 5
Dependent Claim
67 words
A reviewing and collating machine as recited in claim 1 wherein the means for rotatably and removably mounting the takeup shaft comprise a pair of spaced apart cones rotatably mounted on the frame, at least one of the cones being rotated by the driving means and at least one of the cones being spring biased along a direction coaxial with the longitudinal axis of the takeup shaft.
Claim 6
Dependent Claim
61 words
A reviewing and collating machine as recited in claim 1 wherein the means for rotatably and removably mounting the supply shaft comprise a pair of spaced apart guide rails, mounted on the frame in a substantially horizontal position, and vertically extending, hook shaped stop members mounted on corresponding ends of each guide rail to engage the ends of the supply shaft.
Claim 7
Dependent Claim
74 words
A reviewing and collating machine as recited in claim 5 wherein the driving means include a driving gear rotatably mounted on the frame adjacent one of the hook shaped stop members and a corresponding gear is affixed to the end of the supply shaft adjacent the same hook shaped stop member such that the driving gear and the supply shaft gear are engaged when the supply shaft ends engage the hook shaped stop members.
Claim 8
Dependent Claim
43 words
A reviewing and collating machine as recited in claim 1 wherein the surface of the takeup shaft is electrically non-conductive and means are provided for electrostatically charging the non-conductive surface to prevent unraveling of the portion of the web of material wound thereon.
Claim 9
Dependent Claim
150 words
A reviewing and collating machine as recited in claim 1 wherein at least one of the self-centering pulleys comprises a cylinder mounted on the frame, the exterior surface of the cylinder having a circumferential, protruding ridge at its midsection and a plurality of helical, protruding ridges on either longitudinal side of the circumferential ridge, the ridges on one longitudinal side of the circumferential ridge being divergent with respect to the helical ridges on the other longitudinal side of the circumferential ridge in the direction of forward travel of the web of material from the supply roll to the batching roll, the exterior surface of each side of the pulley having a plurality of holes therein, and means for independently supplying gas under pressure to the holes in the surface of each longitudinal half of the pulley, the gas being supplied in equal amounts to each longitudinal half of the pulley.
Claim 10
Dependent Claim
61 words
A reviewing and collating machine as recited in claim 8 further comprising means for rotatably mounting the cylinder on the frame and wherein the helical pattern of the protruding ridges on the external surface of each radial half of the cylinder is a mirror image of the helical pattern on the external surface of the opposite radial half of the cylinder.
Claim 11
Dependent Claim
41 words
A reviewing machine as recited in claim 1 wherein the reviewing surface is positioned in the frame so as to allow open access to the reviewing surface by an operator of the machine for making corrections to the web of material.
