FREMGANGSMAADE VED INDSAETNING AF ET METALLISK ENDESTYKKE I ET ROER AF OPSPOLET KOMPOSITMATERIALE, OG ROER MED ET SAADANT ENDESTYKKE

摘要

Essentially longitudinal fibres (1) are continuously wound both around a cylindrical core tube (4) and around a metallic nozzle having the shape of a double cone, engaged over the core tube, reversing the direction of the winding on spikes (9) distributed over a ring (8) positioned on a threaded portion (11) extending the nozzle, and these longitudinal fibres are then heaped with circumferential fibres (7) before carrying out final polymerisation of the tube. …Application to composite tubes for oil prospecting at sea.
