ABSTRACT:
A pivotal feed head for feeding non-rigid paper sheets individually from a feed hopper to a photo-optical utilization station at high speed without interruption, overlap or collision between sheets including oppositely disposed members for applying a normal force between an enlarged resilient tired feed wheel adapted for unidirectional rotation and a conjointly movable, engageable retard roller. The feed head is mounted for pivotal movement about an outboard drive member. A frictional brake for the retard roller is adjustable to provide a preset load at the nip between the feed wheel and the retard roller while a solenoid-actuated one-way clutch operably engages the feed wheel mounting shaft for incremental signal controlled paper feed. A vertical, signal-controlled latching member locks the feed head in a vertical pivoted position at the end of the vertical upward movement of the paper stack platform as the paper is fed into the nip between the feed wheel and the retard roller.
