Signature loader comprising a telescopically related main floor-mounted frame and a smaller auxiliary frame, first and second horizontal rotatable shafts between the frames spaced apart by a predetermined distance and so positioned that infeed belts thereon converge to define between them a signature infeed throat, one of said shafts being a pivot about which the auxiliary frame may be pivoted so the throat may be selectively positioned in one of two alternate attitudes.

Signature feeder operable with either flat or standing stacks

A sheet feeder has a supply station wherein signatures fresh from the printing press are stacked. The stack is supported such that the signatures are in an arched, non-planar configuration. A sheet stripper extracts signatures successively from the stack and feeds them in a constant stream to a transfer conveyor. The stripper grips the sheets with a suction device which applies a constant but locally intermittent vacuum. The transfer conveyor carries the signatures to a delivery station. The delivery station includes fingers which arch the signatures. Arching the signatures in the supply and delivery stations prevents rolling of the signatures.

Signature feeder having improved signature extraction

Stacking and strapping machines for magazines in which the turning axes for the conveyors which move a stack to be strapped are positioned to enable the stack to be boxed in while being strapped, the conveyors having pushers which in part enable this to be done in cooperation with fixed stops at the strapping station.
