ABSTRACT:
A stencil printing machine includes a rotatable drum having an outer circumferential wall formed by an ink impermeable member, a stencil clamping part for clamping a leading end of a stencil sheet, an ink supply unit having an ink supply opening for supplying a surface of the outer circumferential wall with ink, a press roll for pressing a printing paper against the outer circumferential wall of the drum, an ink recovery unit having an ink recovery opening formed on a downstream side of a maximum printing area in a printing direction to collect ink flowing into the ink recovery opening by suction, the maximum printing area being defined on the outer circumferential wall, and a press unit for pressing the stencil sheet onto the outer circumferential wall of the drum and a control unit for controlling respective operations of the main motor, the ink recovery unit and the press unit. In process of fitting the stencil sheet on the drum while clamping the leading end of the stencil sheet by the stencil clamping part, the control unit allows the press unit to press the stencil sheet onto the outer circumferential wall of the drum and further allows the ink recovery unit to start its sucking operation through the ink recovery opening.
