ABSTRACT:
An ink applying sleeve of resilient micro-porous ink retaining material is confined between a pair of circular flanges mounted on a connecting support hub. A cylindrical ink retaining unit is also mounted on the center hub and is confined between the flanges to support the sleeve. The unit includes a stack of thin plastic discs which define concentric annular ink retaining capillary passages or chambers for receiving a supply of ink. The concentric chambers are interconnected by a series of radially extending passages which control the outward radial flow of ink from the concentric chambers into the micro-porous sleeve. In one form, the thin plastic discs are heat-formed from thin sheet plastics material and have a center hole for receiving the support hub.
