Abstract

Adjustable nozzle arrangement for an injection head for the manufacture of a profile in the form of a sleeve or tube of thermoplastic synthetic material, in which a nozzle coating provided with a flange that protrudes in a circular shape, is pressed by a clamping ring of nozzle against the lower surface of the injection head, and can be displaced radially in relation to a central nozzle core with the aid of displaceable means that can move radially in the nozzle holding ring, characterized in that the opposite circular surfaces between they form on the underside of the flange (3) and on the ring (4) for fastening the nozzles, the running tracks (14, 15) of a bearing (16).
