Abstract

1. A method for applying protective complex coating layers for hoses and channels, characterized by the extrusion from two or several extruding machines (1, 1') of bands of various natures (5, 6) passing thereafter into a single die (3) for forming a band having a single thickness and juxtaposed parallel longitudinal sections of various products used for the coating, said operation being followed by the helical winding of said band on the tubular element (8) to be coated, the helical winding being carried out such that a lower layer (10) of same nature, in one or several thicknesses, is formed on the tube as well as an outer layer (11) of a different nature.
