摘要

Apparatus (1) for creasing and/or cutting a sheet of heat deformable material comprising two opposed platens (7,12) each carrying a forming profile (8,5) and one of which platens (7,12) is heatable via a source (6,13), the platens (7,12) being mountable in the apparatus for reciprocable movement towards and away from each other, characterised in that the forming profiles (8,5) have a complementary configuration (3,5) whereby to form a heat deformable material when the platen(s) is/are heated and are brought towards each other for a predetermined time to define a desired shape in the material.
