Abstract
A stencil printer has a vertical stack of frame-mounted stencils which are supported on one another. Laterally of the stack are arranged holding devices which engage the stencil which is second from the bottom so as to support the stack, while lifting devices are provided which lower the bottom stencil relative to the stack to a printing position and, subsequent to printing, raise it out of the printing position to an intermediate position in which it can be laterally withdrawn from the stack to be placed atop the same. The stack is then lowered by the height of one frame.

In a stencil-printing apparatus, a combination comprising a plurality of stencils each including a stencil frame and a stencil screen mounted in the same;
- interengageable means on said frames for enabling the stencils to be vertically superposed to form an upright stack which is upwardly spaced from a printing plane, said interengageable means including on opposite lateral sides of said frames respective transversely projecting lugs having projections and depressions, said lugs each including two parts and means connecting said two parts for movement relative to one another in the general plane of the respective frame;
- first means for lowering the respectively lowermost stencil of said stack to said printing plane so as to be available for printing onto a workpiece;
- and second means for holding the remaining stencils of the stack upwardly spaced from the printing plane and from the lowered stencil.
