Abstract
Abstract A cartridge for an ink roll is disclosed comprising a pair of cylindrical casing or shell elements each of which has a cylindrical side wall and end walls. The ink roll is encased within the two cylindrical elements which are nested together and mounted for limited relative rotation with respect to one another. Each cylindrical element has an opening in the side wall. The openings are out of registry with one another thereby sealing the cartridge and preventing contact with the ink roll when the cylindrical elements are in a first position. Upon relative rotation of the elements to a second position the openings are in registry so that a portion of the ink roll is exposed for contact by a printing member. A releasable fitting, for example of the bayonet type is provided on the end wall of one of the casing elements. Upon rotation of the other casing element to lock the bayonet fitting the two casing elements are caused to rotate relative to one another to expose the ink roll. Relative rotation of the casing elements in the opposite direction effects release of the bayonet fitting and movement of the casing elements to close the cartridge. Also disclosed are mounting means for moving the cartridge toward and away from the printing members.
