Abstract

A gravure printing roller is manufactured by mounting a core (10), of steel, cardboard or plastics material for rotation, and moving a dispensing head (11) relatively to the core (10) to build up a body (14) of a polyurethane material on the core, and then machining the body (14) to accord with a required diameter. The mixing head combines at least two components of a syntactic or non-syntactic polyurethane immediately before application to the core, and fast reacting amines may be used to produce a gel-like intermediate to aid retention on the core, before complete curing of the polyurethane takes place in the body (14).
