Abstract
In an ink blocking member for a rotary stencil printing machine in which a printing drum has a printing region which is ink-permeable and a non-printing region which is not ink-permeable, for closing a part of the printing region, the ink blocking member is provided on the outer surface of the rear part of the printing region as viewed in the direction of rotation of the printing drum. The ink blocking member defines a space on the outer surface of the printing region of the printing drum which is opened in the direction of rotation of the printing drum, and which is communicated through the printing region with the inside of the printing drum. The ink blocking member is restorable in configuration to maintain the space constant in volume.
