Title:
METHOD AND DEVICE FOR MANUFACTURING POLYMER FORM
Document Type and Number:
Japanese Patent JPS60908
Kind Code:
A
Abstract:
Polymeric foam, particularly polyurethane foam block, is produced in a stationary, longitudinally-extending, channel-shaped, mould (1a). A mixture of foam reactants partially expands in a vessel (40) and overflows down a fall Plate (41) to the bottom ofthe mould. The vessel and fall plate are progressively transported from one end of the mould to the other to lay down partially expanded foam over the bottom of the mould (Figure 1). The ends (11, 12) of the mould may be opened to permit entry and exit of a foam laydown unit (6) and transporting means (7) and to permit removal of the expanded foam strand (61) (Figures 6 and 7). The mould may be covered (14) after foam lay down and means (5) may be provided for removing gases emanating from the foam (Figure 1).
