ABSTRACT:
The sucker assembly is driven into contact with the stack of sheets by a fluid drive air cylinder at relatively slow speed. The stack of sheets is held at a steep incline in the hopper which includes a stock advance drive for keeping the entire stack properly positioned adjacent the sucker pickup point. A pressure sensing transducer measures the vacuum at the suction cupped tip of the sucker and triggers the relatively brisk retraction of a single sheet when proper vacuum is sensed.
