Abstract
Improvements in the extrusion apparatus of profiles, of reticulated plastic material, of the type that comprises, made in a body, an entrance hole and passage means connected to this hole and of reduced cross section, communicating these means with an exit hole by a passage that has the shape of the profile, defined by a set of die and punch, characterized in that the entrance hole (17) opens into the passage means (19) of reduced section by an annular cavity (18) of equal axis (XX) than the row-punch assembly (20-7) and because these reduced section passage means (19) are practiced parallel to this same axis (XX).
