Coupling for a rotary printing screen.

摘要

A rotary printing screen (10) comprises a cylindrical screen (12) of fine nickel mesh removably connected to two coupling devices (14). Each coupling device (14) has a fixed end ring (18) and a movable ring (22) biased by an internal screw threaded ring (32). The adjacent faces of the rings (18, 22) are profiled to form a groove which constitutes a seat for the endless band (26). Movement of the ring (32) causes the band (26) to be compressed and frictionally engage the screen (12).
