<p>The nozzle has a channel for molten mass extending through a cylindrical base body (1). An elongate temperature control element (3) is arranged on the channel. The control element includes heating coils (4a, 4b) at both ends for discharging heat into the base body. A groove (5), large cross-section regions, plugging sleeves, cooling ribs, a pin, a pipeline, an input and a peltier element reduce heat conduction into the base body. The coils are connected by a connecting line (4c), which runs parallel to an axis of the heating coils.</p> |
