ABSTRACT:
A stripping and transfer roller assembly particularly constructed for use in sheet film processors and which includes a pair of cylindrical rollers positioned in closely spaced relation for driving individual sheets of film through a drier and thereafter transfer the same laterally while in substantially upright position into a receiving bin disposed in close association to said rollers, one roller being hollow and having a plurality of pairs of diametrically opposed openings formed therein in axially spaced relation, soft compressible stripping and transfer elements inserted into said hollow roller and aligned with a pair of said openings and having portions thereof normally extending through said openings and beyond the outer surface of said hollow roller, said portions being radially compressed when said sheet passes between said pair of rollers and which expand as said portions rotate out of contact with said sheet, the expansion of said elements stripping the sheet from the stripping roller, said expanded portions then engaging the trailing edge of each stripped sheet to transport said edge laterally and deliver the sheets into said bin in substantially upstanding position in said bin.
