ABSTRACT:
A system for continuously delivering sheets which are provided in successive discrete stacks includes a stack infeed conveyor which includes a cushioned upper holddown belt synchronized to operate with a lower supporting infeed conveyor and to provide stability to stacks of relatively short sheets. A continuous lift apparatus receives successive stacks from the infeed system and utilizes a dual lift apparatus to provide the continuous delivery of stacked sheets which are individually fed from the top of the continuously ascending stack.
