ABSTRACT OF THE DISCLOSURE The present invention relates to an intermittent sheet feeding system for platen presses. The system includes a pair of laterally spaced endless chains carrying sheet gripper bars, a drive shaft carrying drive sprockets for the endless chains and a pair of driven sprockets, one driven by each chain. Each of the driven sprockets is provided with an individual brake. The drive shaft is driven intermittently from a continuously rotating shaft through an appropriate mechanism including a unidirectional drive and the brakes are actuated by a programmer carried by the continuously rotating shaft so that they are actuated in the appropriate timed sequence with the intermittent drive.
