Abstract: Apparatus for conveying upper and lower webs of material having equally spaced, successive, transverse lines of weakening along a longitudinal path and for separating the webs along the transverse lines of weakening. The apparatus includes: a longitudinally extending support structure; a bottom pair of upper and lower, vertically spaced feed rollers rotatably supported by the structure; a pair of upper and lower, vertically spaced burster rollers, the lower burster roller having a shaft and being rotatably supported by the structure downstream of the bottom feed rollers; a clam shell housing pivotably mounted on the lower burster roller shaft, wherein the upper burster roller is supported by the clam shell housing; and a top pair of upper and lower, vertically spaced feed rollers rotatably supported by the clam shell housing.

Abstract: In a copier, copy sheet handling apparatus is provided which includes a pair of feed rollers spaced apart from each other, and a copy sheet tray which extends substantially transversely through a plane which, in turn, extends midway between the feed rollers. Further, the copy sheet handling apparatus includes structure for swivelably supporting the tray in the aforesaid plane; and instrumentalities cooperative with the supporting structure for applying a resilient force to the tray substantially in the aforesaid plane to move the tray toward the feed rollers for disposition of a copy sheet into engagement with the feed rollers, whereby the force is substantially equally distributed between the feed rollers.
