In the production of rigid foam profiles, in particular window profiles, in order to avoid undesired exterior foam coatings of plates (53) inserted into a mould tool, a special recess (51) to receive the plate (53) is provided in the mould cavity and a plate (53) is used whose leg (54, 58), during the foaming process of a reaction mixture forming the rigid foam, bears sealingly, at least along a desired line, against that delimiting surface (57, 60) of the recess (51) assigned to said leg (54, 58). <IMAGE>
