ABSTRACT:
A screen printing machine has an endless stencil which is trained about a plurality of supporting rollers. A squeegee roller defines with a portion of the inwardly directed stencil surface a trough into which printing medium can be fed to form a medium pool therein. Confining elements extend across the trough at locations spaced lengthwise of the same and have surface portions which sealingly and slidably engage the squeegee roller and the inwardly directed stencil surface, respectively, to prevent undesired escape of printing medium from the pool.
