Document stacking and conveying apparatus

A document stacking and conveying apparatus comprising;

• A. a pair of elongate document stacking and conveying devices arranged in parallel relationship, each of said document stacking and conveying devices having means for accumulating a plurality of documents into a stack adjacent one end of said document stacking and conveying device and for intermittently feeding said stack beyond said one end,
• B. a third elongate stacking and conveying device disposed in perpendicular relationship to said pair of document stacking and conveying devices adjacent said one end thereof for receiving said stacks therefrom and for stacking said stacks one on top of another, said third document stacking and conveying device comprising;
• 1. means adjacent said one end of said pair of document stacking and conveying devices for receiving and supporting said stacks therefrom,
• 2. conveyor means extending along said third document stacking and conveying device for sequentially moving one of said stacks toward the other stack while said other stack remains stationary on said stack receiving means and for moving both said stacks after said one stack has been deposited on top of said other stack, and
• 3. means disposed between said stacks for compressing said other stack toward said receiving and supporting means and for guiding said one stack upwardly from said receiving and supporting means whereby said one stack is deposited on top of said other stack by said conveyor means while said other stack remains stationary.
