ABSTRACT:
An endless printing screen is trained about two or more guide rollers for traveling an endless path. Abutment members in form of longitudinally continuous or discontinuous elements are mounted on the respective lateral edge portions of the screen, extending from one of the screen surfaces. Tensioning units are mounted adjacent these edge portions and are provided with grooves through which the abutment members travel. Each tensioning unit at one of the lateral edge portions is connected with a tension unit at the opposite lateral edge portion by an arrangement which makes it possible to move the tensioning units apart from one another in direction transversely of the travel of the printing screen, thereby tensioning the printing screen. The thus-connected tensioning units can also be moved in toto in direction transversely of the travel of the printing screen.
