Abstract
Lifts or sets of precise count are withdrawn from a stack of sheets. A reciprocating vacuum head serially pulls away sheet corners from the stack. Each sheet is stripped from the head and held by the backside of the head at a holding zone axially spaced apart from the stack until the desired quantity in the set is accumulated. A wedge then interposes in the space between the set of restrained corners and the rest of the stack, to bend the upper half of the sheet set away from the stack while the rest of the set remains in contact with the stack. Then nip rollers engage the bent away parts as a set and draw away the whole of the set transversely.
