Abstract

A mold (1) which surrounds an article (5) to be coated with an elastomeric material (20) employs a number of actuators (4) which can be extended to cause plugs (8) mounted on end caps (3) to engage on the article (5) to hold this in position in the mold (1). After the coating (20) has hardened the actuators (4) can assist in separating the mold (1) from the coating (20). The cavities left in the coating (20) can be filled and/or a further coating built-up to provide a continuous outer skin to the first coating (20) by treating the coated article (5) in another similar mold.
