ABSTRACT:
A plastic foam-forming mixture, e.g. a polyurethane or polyisocyanurate foam mix, deposited on a carrier, is metered through two spaced opposed members forming therebetween a metering gap. At least one of the members is malleable through changes in temperature so that the profile of the metering gap can be variously defined. Foam boards having a highly uniform thickness are thereby continuously and expeditiously producible.
