摘要: Polymeric foam, particularly polyurethane foam block, is produced in a stationary, longitudinally-extending, channel-shaped, mould (1a). A mixture of reactants partially expands vessel (40) and overflows down fall plate (41) to the bottom mould. The are progressively transported from one end other lay expanded over (FIG. 1). ends (11,12) may be opened permit entry exit lay-down unit (6) transporting means (7) removal strand (61) (FIGS. 6 7). covered (14) after (5) provided for removing gases emanating
