The invention relates to an extrusion nozzle head (1), preferably a blow head, substantially comprising an inner mandrel (4) and a sleeve (5) which delimit a nozzle gap (3). The inventive extrusion nozzle head (1) further comprises at least one heating element (14) by means of which the nozzle gap (3) can be heated. The heating element (14) can be inserted into the inner mandrel (4) in the area of the nozzle gap (3) and is supplied with electricity via feed wires (18) that are guided through passage bores (19) which are incorporated into the inner mandrel (4). The novelty of the inventive extrusion nozzle head consists of the fact that the at least one heating element (14) and the feed wires (18) can be joined to each other via connecting elements (17). |
