ABSTRACT:
A bottom sheet separator-feeder for separating and forwarding sheets seriatim from the bottom of a stack of sheets to be fed. It comprises a stack tray defining a surface for supporting a stack of sheets to be fed, the tray having a depressed control portion in at least the front part of the surface. Vacuum feed belts are disposed in the pocket to pull the bottom sheet in the stack into the pocket and feed the sheet from beneath the stack. An air injection knife disposed adjacent the front of the tray injects air between the bottom sheet in the stack and the tray and between the bottom sheet and the remainder of sheets in the stack. Ramps are provided at the front ends of the tray at each side of the pocket for raising the lead edges of the sheets in the stack above the support surface to control multifeeds and misfeeds of downcurled sheets.
