An apparatus, by means of which the stencil end rings of screen printing cylinders composed of metallized steel wire mesh are semiautomatically inserted in exactly the same position in the cylinder jacket, adjusted, and with the application of heat-hardening adhesive are placed in the cylinder jacket after cooling and the consequent shrinking of the screen printing cylinder, the stencil end rings, because of their parallel spacing, their parallelism and their axial alignment precisely, control the positioning of the end plates.
