A method for the extrusion of multilayer sheets, characterized by comprising a phase of displacement of a first hot-plastified material by a passage having a predetermined cross-sectional shape, by arranging a layer of a second hot-plastified material on an area less than 180º of the surface of the first material, with which a plane can be passed through the edges of said second material and also longitudinally through said first material and displacing the combined and plasticized assembly of said first and second materials by a co-extrusion matrix, distorting the shape of said combined materials together from their original cross-sectional shape and expanding it into the form of a broadleaf thinner than the original form of said first and second materials and whose sheet extends substantially in said flat.
