A method to produce shaped multi-layer plates having super-imposed layers includes individually extruding raw materials comprising powder, granules, or crystals, in liquid form, to form a plurality of separate layers, each layer being mono-component or multi-component, superimposing the separate layers, co-extruding the superimposed layers through a co-extrusion head with plane lips to form a continuous flat multi-layer plate with a plane surface, subjecting the flat multi-layer plate emerging from the co-extrusion head to a calendering pass to provide thermal, chemical and dimensional stabilization, subjecting the flat continuous multi-layer plate emerging from the calendering pass to a pass of thermal adjustment and shaping, and cooling and shearing to size the shaped multi-layer plate emerging from the pass of thermal adjustment and shaping so as to obtain shaped multi-layer plate of the desired length.
Method to produce shaped multi-layer plates, comprising super-imposed layers, the method comprising:
Plant for the production of shaped multi-layer plates, comprising super-imposed layers made of thermoplastic resin obtained by a process of extrusion from ray materials in powder, in granules, in crystals, in liquid form, optionally with additives, each layer being able to be of the mono-component or multi-component type, the plant including at least a mixing and homogenization device, a cooling device, extrusion assemblies to obtain the layers, a feeding assembly and an extrusion head, the plant being characterised in that it comprises:
