ABSTRACT:
The present invention provides a printing drum for a rotary stencil printing device, comprising: a clamp for clamping a leading edge of a stencil master plate sheet along a line extending axially on an outer circumferential surface of the printing drum; and cutting device mounted on the printing drum for cutting the stencil master plate sheet to define a trailing edge of the stencil master plate sheet mounted on the printing drum. By thus providing the cutting device on the printing drum, the stencil master plate can be accurately cut because the cut length of the stencil master plate can be determined in relation with the circumferential length on the printing drum, and the cut edge of the stencil master plate can be made always exactly parallel to the axial line of the printing drum because there is no relative movement in the feeding direction between the stencil master plate sheet and the cutting device.
