Abstract

Prodn. of continuous cast materials, recovered without being bonded to the support on which they are cast by release from the travelling surface and associated foam hedges with the aid of an anti adhesion varnish. PRef. the casing support is a continuous belt which on the return loop passes through units which removes residual cast material and apply a fresh coating of anti adhesive material. Suitable for mfg. continuous cast polyurethane films or foams. Typically the anti adhesive coating is a silicone resin based varnish.
