INSTALLATION AND METHOD FOR THE CONTINUOUS PRODUCTION OF A THERMALLY OR ELECTRICALLY INSULATED TUBE OR CABLE, TUBE OR CABLE THUS OBTAINED AND APPLICATION TO THE PRODUCTION OF DOUBLE ENVELOPE PIPES

摘要

The invention relates to an installation (1) for continuously placing a thermal or electrical insulating material (6) around a circular section element (2). The installation comprises a forcing member (3) in the form of a frustoconical tube in which is engaged at its large base simultaneously said element (2), a sheet (4) on which the insulating material (6) ) is provided, means for translational driving said circular section member (2) and said sheet (4) and means for depositing (7) said insulating material on said sheet, said sheet being in the form of a material metallic or plastic. Application to the production of thermally insulated tubes or electrically insulated cables.
