    Abstract: A die for producing wide, flat, plastic-based structures including a base and a cover. The die includes a plurality of ducts for feeding molten plastic, opening into a distribution channel, and a longitudinal outflow slot for outputting the molten plastic in a form of a substantially flat structure. The distribution channel and the outflow slot communicate via a plurality of distributors of generally triangular section having a downstream apex, near to which a feed duct emerges, and two upstream apexes forming intersections of the distribution channel and of the outflow slot, each feed duct being fed with molten plastic via an upstream orifice of the die that is specific thereto.
