ABSTRACT:
A rotary stencil printing machine is formed of a cylindrical member, a clamping device formed on the cylindrical member for clamping a leading edge portion of a stencil sheet, and a back-up device provided outside the cylindrical member. The back-up device grips a printing sheet together with the cylindrical member to transfer the same. The cylindrical member includes a cylindrical peripheral surface for mounting thereon the stencil sheet; a first ink-pervious area formed on the peripheral surface on which an image forming area of the stencil sheet is disposed; at least one second ink-pervious area formed on the peripheral surface on which a trailing edge portion of the stencil sheet is disposed; and at least two first ink-impervious areas formed on the peripheral surface. The second ink-pervious area has an elongated shape continuously extending parallel to a center axis of the cylindrical member, and the ink-impervious areas sandwiches the second ink-pervious area.
