Abstract

1,230,073. Producing slabs of polyurethane foam. AEROPREEN Ltd. 20 May, 1968 [18 May, 1967], No. 23231/67. Heading B5A. Flexible slabs of polyurethane foam are made by pouring the mixed ingredients for the foam on to a web of paper supported on a conveyer which carries the paper webs away from the position at which the foam ingredients are poured on to it. The supporting surface or surfaces of the conveyer consist of a material having a low coefficient of thermal conductivity, i.e. of less than one B.T.U. unit. The material of the conveyer surface is a flexible foam plastics material, e.g. polyurethane or rubber.
