ABSTRACT:
Foam molding apparatus wherein individual molds filled with a flowable foam-material mixture are subjectible in a hardening operation to a heating and subsequent cooling interval, includes a rotatably driven table carrying a plurality of the molds for hot-foam molded articles, means for directly and individually heating and cooling the molds, a central rotating distributor head carried by the table, and individually closable connecting lines which, with the central rotating distributor head, connect the individual molds to corresponding heating, cooling and energy-medium supply sources, and method of operation thereof.
