Stencil printing machine and a wrinkle preventing method on a stencil sheet of the stencil printing machine
Abstract:
An ink supplying roller (17) is disposed in a rotary cylindrical drum (16), and is moved so that the ink supplying roller (17) can be brought into contact with an inner peripheral surface of a cylindrical circumferential wall (15). The ink supplying roller (17) is placed at a contact position with an ink permeable portion (15a) of the circumferential wall (15). The rotary cylindrical drum (16) is rotated in a state in which a stencil sheet (M) is not wound around the rotary cylindrical drum (16). Therefore, ink (50) drawn out through the ink permeable portion to the outer peripheral surface of the circumferential wall (15) because the stencil sheet (M) is peeled off at the stencil discharging operation is pulled into the ink permeable portion of the circumferential wall (15) by negative pressure produced by the ink supplying roller (17) coming in contact with the inner peripheral surface of the circumferential wall (15) and is removed.
