ABSTRACT:
A plate clamping apparatus for a leaf-type printing machine which enables substantially automatic plate clamping and stretching operations. Top and bottom side plate clamps are respectively provided with upper and lower teeth for clamping and releasing the top and bottom side end of a plate by rotating top and bottom side cam shafts. A plate stretcher moves the bottom side plate clamp in a stretching direction or a releasing direction of the plate by rotating a plate stretching cam. Top and bottom side cam followers are respectively coupled by a joint to transmit rotation to the top and bottom cam shafts. A motive force transmitting mechanism is attached to a rotating shaft of the plate roller. A groove cam puts the top and bottom side cam followers into a predetermined action for rotating the top and bottom side cam shafts.
