ABSTRACT:
A forming tool for the production of sheets, more particularly from a thermoplastic synthetic material, is in the form of a roller, a press, or a casting mould, and comprises, upon its outer surface, engraving elements in predetermined spatial relationship with each other. It is to be possible to produce sheets inexpensively with this apparatus, and production tolerances are low. The engraving elements are provided upon the outer surface, which is made of hard material, more particularly metal. The engraving elements project, above the outer surface, to a predetermined height, and the remainder of the outer surface exhibits a predetermined surface structure.
