DEVICE AND METHOD FOR EXTRUSION-COATING TUBES OR COMPOUND TUBULAR CONNECTION FITTINGS WITH RUBBER OR PLASTIC

摘要

The invention concerns a device for extrusion-coating tubes or for sealing the connection zone of compound tubular connection fittings with rubber or plastic, in particular for extrusion-coating hose connectors. The device comprises a metal or plastic connection pipe (5) on to which the length(s) of rubber or plastic hose (7) is/are pushed. The invention consists essentially in the fact that, in addition to the fixed moulding-tool surface (1) with the injection nozzles, the device has at least one, in particular at least two, slide clamps (2) per circumferential unit, the sealing surface (3) of the clamps having substantially the same profile as the surface of the article immediately opposite it in the sealing zone.
