A signature feeding machine of the type having suction grippers for removing a signature from a hopper. A vacuum is applied to the gripper when grabbing a signature. The gripper transports the signature to a rotating cylinder where the gripper releases it by disapplying the vacuum. The machine is operable in two modes; a run mode and a jog or intermittent mode. An adjustable timing control is provided to time differently the application and disapplication of the vacuum in accordance with the particular mode of operation.

Signature machine having an adjustable timing control of the extraction

Signatures fresh from the printing press are fed in a shingled stream toward and then dropped one by one into a hopper which may feed a gathering chain. The signatures are 'broken' (unstuck) by first stacking them edgewise on horizontal support, shingling them in a constant stream by an unusual form of suction feed, bending the shingled stream and thereafter cascading the stream into the hopper.
