Abstract

The invention concerns a section of cellular structure made of thermoplastic resin in which the cells are arranged substantially perpendicular to the axis of the section. The section is made with an extrusion apparatus consisting of an extrusion head and extrusion tooling of which the extrusion head is divided into three channels substantially superimposed opening substantially into the corresponding three channels of the extrusion tooling and at the opposite end being connected with the feed conduit of at least one extrusion device, the two outer channels being used to carry the material constituting the outer walls of the section or tube and the intermediate channel being used to carry the material for fabricating the walls of the cells, the said apparatus being distinguished in that each of the outer channels is separated from the intermediate channel by an annex channel, ending at the outlet in line with those of the other channels and of which the intake, outside the apparatus, is designed to be connected with a means of varying pressure. The section is obtained by creating an alternative pressure variation in the annex channels.
