ABSTRACT:
A printing roller is disclosed comprising a mandrel fitted with a removable cylinder. The cylinder is retained on the mandrel by radially expansible, resilient rings which extend around the mandral. In one embodiment, the mandrel includes a number of cylindrical sections between which the rings are disposed and means are provided for compressing the sections to cause radial expansion of the rings. In other embodiments, the roller mandrel has an internal air passageway which communicates with the grooves receiving the rings and provision is made for delivery of pressurized air to the air passageway so as to cause the rings to expand.
