ABSTRACT:
A sheet feeder with a feed wheel assembly for conveying an end sheet from a stack of sheets. The feed wheel assembly has a rotatable engagement wheel positioned to contact the end sheet of the stack, and operable to separate and convey the end sheet from the stack; a horizontally extending first shaft on which the wheel is mounted, with the first shaft being angularly movable in a generally vertical direction; a horizontally extending second shaft positioned spaced apart from the first shaft, the second shaft being mounted in a substantially fixed planar orientation to a support frame; and a pair of laterally spaced-apart first and second arms extending between the first and second shafts. Each of the first and second arms has a first portion retaining the first shaft and a second portion longitudinally spaced from the first portion and pivotally connected to the second shaft. The first and second arms are independently-pivotally movable about the second shaft within at least a limited range to permit uninhibited angular movement of the first shaft in a generally vertical direction during operation.
