  • Extrusion Moulding Of Plastics Or The Like (AREA)

Abstract

This invented procedure is characterized by the simultaneous extrusion of at least two plastic laminates, one adhesive, the other protective; to solidly unite, between themselves, the longitudinal borders of these laminates, so as to form a composite "C" shaped lamina, and to wind, and then adhere the latter to the periphery of the pipe or similar (D) in the plastic state, to produce a differentiated and distinct superimposition of the two or more elementary layers making up the protective covering.Advantageously, the two or more lamina are produced by means of simultaneous multiple extrusion or co-extrusion, where the individual constituent materials, that is, the two or more elementary layers, are solidly united between themselves by extruding them simultaneously in a multiple head (A), at the exit of which, the composite lamina exits (C), in which the contiguous longitudinal borders of the two or more elementary lamina are solidly united between themselves. The composite lamina obtained, still in the plastic state, is wound elliptically around the pipe to form two or more superimposed layers, whose composition is axially homogeneous and uniform.
