发明名称 Stencil printing drum which prevents ink leakage
摘要 A stencil printing drum comprises: a rotary cylindrical drum including an ink non-passage region, an ink passage region surrounded by the ink non-passage region, and an axis around which the rotary cylindrical drum rotates; an ink supplying roller whose axis of rotation is in parallel with the axis of the rotary cylindrical drum, the ink supplying roller being brought into contact with the inner cylindrical surface of the rotary cylindrical drum to push a printing ink out of the rotary cylindrical drum through the ink passage region; and an ink non-passage strip formed along the border between the ink non-passage region and the ink passage region except the start end portion thereof as viewed in the direction of rotation of the rotary cylindrical drum, in such a manner that the ink non-passage strip protrudes radially inwardly of the rotary cylindrical drum.
