Abstract:

An apparatus for facilitating the movement of a printing sleeve with respect to a cylinder is provided which includes a manifold section having an air chamber therein in fluid communication with an air supply line. The manifold section has a plurality of air ports in fluid communication with the air chamber. An adapter ring is provided which surrounds the manifold section and has a plurality of air ports therein, corresponding in number to the air ports in the manifold section and adapted to be placed in fluid communication with the air ports in the manifold section. A locking collar for fixing the position of the manifold section on the shaft in contact with the cylinder and for fixing the adapter ring in contact with the printing sleeve is provided such that when pressurized air is introduced into said supply line, the air exits the air ports in the adapter ring and expands the sleeve thus allowing the sleeve to be moved with respect to the cylinder.
