Abstract: Method, for manufacturing a composite pipe (CP) with a tubular wall, this wall comprising at least one extruded tubular part (1), referred to as the first tubular part (1), this first tubular part (1) being made up of a first polymeric material (100), this method being characterized in that the step of extruding the first tubular part (1) of a first polymeric material (100) involves the use of a first polymeric material (100) of the type capable of being cross-linked by infrared radiation, and this step of extruding the first tubular part (1) of said material is immediately followed by a step of irradiating the extruded first tubular part (1) with infrared radiation in order to accomplish said cross-linking reaction.

Abstract: The closure device is intended to hold the free end of an elongated element on a winding collected on a winding station during the operations of making ligatures on this winding. The device includes a support, capable of being set in rotation about a shaft coaxial with the winding, and two means of actuating bent arms, pressing portions of which are capable of clamping the last layer of the winding. This device makes it possible to automate the finishing operations of the winding. Furthermore it makes it possible to aid in discharging the finished winding from the winding station.
