ABSTRACT:
A self-inking stamping device of the type which inverts as it travels between inking and printing positions upon movement of an actuating member. A stamping insert is pivoted on the actuating member and comprises a frame which is provided with a fixed printing plate and a stamping belt unit movably mounted in the frame of the stamping insert and comprising a plurality of juxtaposed parallel endless stamping belts, which are longitudinally adjustable relative to each other and carry type protruding through an aperture of the printing plate. The stamping belt unit is adjustable by a screw mechanism in a direction which is normal to the plane of the printing plate. In order to ensure that the inking and printing operations will always be performed under the same conditions, regardless of the thickness of the printing plate, the pivot of the stamping insert is held without backlash in the stamping belt unit, the frame of the stamping insert is provided with slots, which are normal to the plane of the printing plate, and the pivot extends through said slots so that said pivot is adjustable relative to the frame along said slots in unison with the stamping belt unit.
