Device and method for cleaning a surface of a rotating cylinder, such as a platecylinder of a printing press or other

摘要

From the side wall (15F) of the gearcase (15) there develops a top wall (115, 115B) beneath the fixed top flange (3) as far as an annular seat of very limited diameter for an O-ring (117) which co-operates with a corresponding wall (9A) of a piece (9) which is fixed as the fixed gear (10); in this way, the speed of sliding of the O-ring (117) is very limited.
