Abstract

A reinforced flexible sheet is used to line the cavity faces of a rigid moulding tool made of >=1 solid component. The liner is made of latex reinforced with a flexible, nonwoven mat made of relatively inextensible fibres, e.g. of glass, supplemented in the zones to be subject to peak tensile stresses by fabric made of rot proof material, e.g. of polyamide yarns. Opt. the liner also incorporates a low-friction fillers, e.g. talc, to obtain sufficient rigidity to retain sharp surface detail without loss of overall flexibility for disengagement of a moulding. The sheet provides sufficient flexibility and extensibility to disengage detailed or slightly undercut mouldings. The rigid supporting mould ensures reproducibility of the moulding form, e.g. for making large, textured blocks of reconstituted stone or marble. The moulds and their liners may be repeatedly re-used.
