Abstract
A rotary printing screen, for mounting in a rotary screen printing machine, which has a support member at each end of its screen cylinder. The support member uniformly supports each endring against the longitudinal tension applied to the screen cylinder by the tensioning device so that the endrings remain in parallel. The support member, made from a heat-shrinkable plastic, such as polyethylene terephthalate, is selectively a heat-shrunk plastic sleeve or a heat-shrunk device endwise extension of the screen cylinder. Each embodiment extends over at least a portion of the shoulder of the endring to form a lip which has progressively greater thickness and decreasing circumference, terminating in a circular bead. As a sleeve, the support member fits over each terminal portion of the screen cylinder and covers its adhesive joint with the underlying cylindrical surface of the endring.
