Abstract

1,167,844. Moulding plastic materials. FRIED. KRUPP G.m.b.H. 9 Jan., 1968 [10 Jan., 1967], No. 1270/68. Heading B5A. A body of cellular plastics material for use as a buffer is made in a mould 1, 2 to which the raw material is fed through three tubes 6, 7 and 8 disposed in the annular gap between a tube 4 and a cone 5 and compressed air is fed through the spaces between the tubes 6, 7 and 8 and imparts a whirling motion to the material leaving the tubes 6, 7 and 8. The material then passes through the mixing head formed by the deflector 11 and the wall 10 of cooling jacket 9 and is distributed uniformly over the base 1, the foaming action starting at the same time. The mould 1, 2, the core 5 and the deflector 11 can be rotated during foaming. The mould has a cooling jacket 12.
