Abstract

A method is disclosed of making in a mould cavity objects having an outer wall from a micro-cellular or non-cellular elastomer (7) and a core consisting at least partly of a synthetic foam (9), including the following steps: in a first step, a layer (7) of the elastomer is applied by spraying onto the surface (1) defining the mould cavity, and then, in a second step, before the elastomer is completely cured, a reaction mixture for obtaining a synthetic foam (9) is injected in the thus by the formed elastomer layer (7) defined space (8) of the mould cavity and wherein, in a third step, after the synthetic foam (9) has been cured substantially completely and forms a whole with the elastomer layer (7), the thus obtained object is demoulded.
