Abstract

The rubber surface is a piece of natural rubber suspended across the profile of the die surface, which can be sucked into the moulding profile by evacuating air from between the rubber and the mould surface. Rubber prevents the moulding from sticking to the mould and no air bubbles can become trapped between it and the mould surface. Process is used for shallow dishes etc.
