ABSTRACT:
Thin sheets on which a product is held by limited adhesion are transferred from a first conveyor onto a speedup conveyor which slides the sheets, one by one, onto a pair of intermittently rotatable paddles. The paddles comprise a lattice of low-friction material and define receiving surfaces angled toward one another along a direction in which the sheets slide. The paddles rotate 1/2 revolution in response to the leading sheet on the speedup conveyor passing a photocell and form a stack in a compartment on an intermittently moving conveyor below. When a predetermined count of sheets is in the stack, the intermittently moving conveyor is advanced to move an empty compartment under the paddles.
