ABSTRACT:
The apparatus includes molding a plurality of recesses on a layer of foam material which is laid on a laying surface and moved forward. These recesses include a base open on the laying surface and are subsequently cross-linked by introducing steam under pressure through the bases of the recesses into cavities of the recesses formed during the molding step. The apparatus includes a conveyor element in which a plurality of plates disposed side-by-side are provided with protuberances corresponding to the recesses to be formed in the foam layer. The protuberances are open at their bases to enable introduction of steam into an inner space within each of the protuberances.
