ABSTRACT:
Duplicating machine having a drum rotatably mounted between a pair of side frames. Drum has a cylindrical wall having perforations communicating with an internal ink reservoir. An open mesh screen is stretched about the drum to provide an external cylindrical auxiliary reservoir immediately beneath an ink-distributing pad. Copy sheets are fed from a stack by adjustable pressure feed wheels and advanced along a path of movement to a first bight between a pair of forwarding rollers, and then to a second bight between an impression roll and the drum. Automatic apparatus is described for positively gripping a stencil sheet including provision for guiding the impression roll in non-interfering contact with the gripper assembly and for automatic alignment of the front edge of the stencil with the drum axis upon the positive clamping of the stencil sheet.
