Abstract
A process and apparatus for the continuous production of polyurethane foam are directed to the use of a laterally translating mold 13, the first portion of which has divergent side walls, including a "V"- shaped mold (12) having divergent straight vertical side walls (14). A polyurethane reaction mixture is deposited via conduit (11) at or near the mold apex the angle of which is 10 DEG to 120 DEG . Typically, the mixture is permitted to substantially complete its rise after being conveyed past the extremities of the divergent side walls (14) of the first mold portion. The invention contemplates use of a ratio of conveyor velocity to foam product height lower than those of the prior art. Both rectangular and circular cross sectional products can be produced. <IMAGE>
