<p>The present invention is directed to a rotary stencil printing machine in which a printing stencil is obtained from a stencil sheet. According to the present invention, said rotary stencil printing machine comprises a: stencil making means for processing the stencil sheet to obtain the printing stencil; a printing drum having an outer cylindrical surface and clamping means which clamps the front end portion of the stencil sheet thus processed by said stencil making means, said printing drum being turned with the front end portion of the stencil sheet clamped with said clamping means to wind the stencil sheet on said outer cylindrical surface thereof; conveying means for conveying the stencil sheet, which has been processed by said stencil making means, towards said printing drum; movable guide means 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 said stencil making means and said printing drum, said movable guide means moving from said standby position to said holding position, for lengthening a stencil conveying path between said stencil making means and said clamping means; urging means for urging said movable guide means towards said holding position; holding means for holding said movable guide means at said standby position against said urging means, and for, after the stencil sheet is held on the side of said printing drum rather than on the side of said movable guide means, releasing said movable guide means; and damping means which, at least when said movable guide means is initially moved from the standby position to the holding position, resists said movable guide means to decrease the force of movement of the movable guide means which is urged by said urging means. <IMAGE></p> |
