<p>A printing drum supporting device for a stencil printing machine comprises a forward side-plate (2) and a rear side-plate (4) disposed at a certain distance therebetween, a frame (13) for supporting the drum, a rail device (14,16) disposed between the two side-plates for guiding the frame, and a pipe (80,82) disposed between the two side-plates. The frame includes a forward plate (8) and a rear plate (11) disposed at a certain distance therebetween. The rear plate has a hole (86,88). The frame supports a rotatable cylindrical printing drum (6) between the forward plate and the rear plate. The frame is detachably supported by the rail device. The frame can slide along the rail device between a printing position inside the two side-plates and a disengagement position outside the same. The pipe (80,82) is fixed between the two side-plates. An end portion (80a,82a) of the pipe is protruding outside through the rear side-plate. An axis of the hole of the rear plate is located vertically beneath an axis of the pipe at a small distance when the frame with the drum is pulled out to the disengagement position. When the frame with the drum is guided to the printing position, the end portion of the pipe (80a,82a) is fitted into the hole (86,88) of the rear plate and the rear plate of the frame is raised small vertically. Thus a frame load of the rear plate side is carried by the rear plate and the pipe. <IMAGE></p> |
