Abstract
A stencil printing apparatus for printing a workpiece web at a printing station has a support on which the workpiece web is to be located so that a pattern can be printed on it in a plurality of successive printing operations. A magazine is located above the support at the printing station and accommodates a plurality of vertically stacked flat-screen stencils, and an arrangement is provided for serially withdrawing some or all of the stencils from the magazine, moving them to printing position above the workpiece web, and then returning them serially back to the magazine.

Stencil printing apparatus for printing a workpiece web at a printing station, comprising support means for supporting at the printing station a workpiece web onto which a pattern is to be printed in a plurality of successive printing operations;
- a magazine adjacent said support means at the printing station;
- a plurality of flat-screen stencils in said magazine and each provided with at least part of the pattern to be printed;
- and transferring means for successively transferring the respective stencils from said magazine to a printing position in which the stencil is located above the workpiece web for printing onto the same, and subsequently back into said magazine, said transferring means comprising a raising and lowering device for said stencils, including upright support means adjacent said magazine, an upper and a lower stencil-supporting carriage movable along said upright support means, means for mounting said carriages for movement along said upright support means, and conveying means on at least one of said carriages for substantially horizontally moving respective stencils between said magazine and said at least one carriage.
Stencil printing apparatus for printing a workpiece web at a printing station, comprising support means for supporting at the printing station a workpiece web onto which a pattern is to be printed in a plurality of successive printing operations;
- a magazine adjacent said support means at the printing station and comprising a frame structure including uprights located at respective corners of said frame structure;
- a plurality of flat-screen stencils in said magazine and each provided with at least part of the pattern to be printed;
- and transferring means for successively transferring the respective stencils from said magazine to a printing position in which the stencil is located above the workpiece web for printing onto the same, and subsequently back into said magazine, said transferring means comprising at least one pair of stencil lifting and lowering devices in said frame structure and said devices each comprising at least one upright bar provided with at least one carrier, said carriers being arranged opposite one another, and means for displacing said bars in the axial direction thereof and also for rotating the respective bars about their upright axes between first and second angular positions in which stencils supported on said carriers are located inside and outside of said frame structure, respectively.
