Abstract
A rotary stencil printing machine includes: stencil making section for processing the stencil sheet to obtain a printing stencil; a printing drum having an outer cylindrical surface and a clamping member which clamps the front end portion of the stencil sheet thus processed by the stencil making section, the printing drum being turned with the front end portion of the stencil sheet clamped with the clamping member to wind the stencil sheet on the outer cylindrical surface thereof; a conveyer for conveying the stencil sheet, which has been processed by the stencil making section, towards the drum; a movable guide which is movable between a standby position and a holding position which are spaced away from each other in a direction perpendicular to the surface of the stencil sheet located between the stencil making section and the drum, the guide moving from the standby position to the holding position, for lengthening a stencil conveying path between the stencil forming section and the clamping member, wherein the guide receives the force by its own weight towards the holding position; and a pin for holding the guide at the standby position against its own weight, and for, after the stencil sheet is held on the side of the drum rather than on the side of the guide, releasing the guide.
