Abstract: The disclosed rotary duplicating mimeograph machine comprises an endless belt type rotating screen, a clamping and a stencil raising element disposed on the screen adjacent to each other, and a rectangular bit of cut stencil paper with a head somewhat thicker than its main body disposed on the screen by having the head clamped by the clamping element and engaged by the raising element. After the printing, a cam actuates the two elements to release the head and then raise the head. Two takeup pawls disposed in spaced relationship with the screen outside its opposite edges are operated to engage the head and wrap the stencil bit about the head. A stencil discharging element located between the pawls is turned to discharge the wrapped bit disengaged from the pawls to a receptacle disposed below it.
