Abstract

A former for producing e.g. plaster moulds for moulding plastics is built up from an assembly of modular blocks which are pref. marked so that the blocks can be assembled according to a plan, and pref. the assembly is covered with a heat shrinkable plastic film to cover the joins between the blocks. The blocks may be cubic etc., and some of the blocks may have contoured (e.g. cylindrical or spherical) surfaces. The blocks may be secured together by adhesive, or by magnets embedded in the blocks. Different shaped formers can be rapidly produced.
