Abstract

A process for the coextrusion of multilayer sheets of thermoplastic materials, characterized by comprising a joining phase in a tube of two streams of molten thermoplastic resin with laminar flow, forming a combined stream of molten thermoplastic resin having a clearly defined bond between the components of said combined current, by passing said combined current flow, from thermoplastic resins to a manifold of a sheet extrusion die, with the planes of junction between each of the individual resin components being parallel to the principal direction of flow of the resin itself passing through the collector, adopting the shape of a sheet and so that in the multi-layer sheet, the individual layers of thermoplastic resin are of practically uniform thickness over the entire width of the sheet.
