ABSTRACT:
A mimeographic transfer printing machine includes a stencil support drum for supporting a stencil, an ink supply device for forcing ink through the stencil supported on the stencil support drum, an ink receiving transfer drum to which the ink forced out from the stencil is to be transferred, and a sheet support device for supporting a printing sheet to which the ink on the ink receiving transfer drum is to be transferred. The stencil support drum has a slightly larger diameter than the transfer drum so that the circumferential speed of the stencil support drum is greater than that of the transfer drum to provide to the stencil a tension acting in a direction opposite to the rotation of the stencil support drum.
