Abstract
A stencil duplicator includes stencil ejection apparatus including a mechanism to release the clamp for the stencil head, a guide to lead the head, as the duplicator rotates, to drive members which forward the used stencil into a container in which it is folded or creased so as to be foreshortened and stored with other stencils in a small space prior to disposal.
Claims12
A stencil duplicator comprising a rotary surface upon which stencils are to be positioned, a clamp on the surface for clamping stencil heads upon the surface, means for driving said rotary surface in a print direction at a printing speed and stencil ejection apparatus, said stencil ejection apparatus including:
- (a) a mechanism operable to release the clamp during rotation of the surface, whereby the head of a stencil on the surface will be raised therefrom;
- (b) circulatory drive members so positioned adjacent the surface as to receive a so raised stencil head between them upon continued rotation of the surface;
- (c) a container mounted adjacent the circulatory drive members;
- (d) intermeshing toothed surfacing means for forming toothed surfaces on said circulatory drive members;
- and
- (e) means for driving said circulatory members in use of the stencil ejection apparatus for conjoint circulation entraining said stencil along a direction to draw the stencil from the surface as it moves in said print direction by holding the stencil between said intermeshing toothed surfacing means of the respective drive members, and then to release it into the container at a speed corresponding to the speed of movement of said rotary surface when rotating at said printing speed.
