The hose head has a sleeve-shaped housing (1), in which melt is fed. The housing surrounds a core (2). A sleeve-shaped nozzle (3) surrounds the core. The housing and the core surround the core such that a closed flow channel (5) is provided between the housing and the core, and between the nozzle and the core. A peripheral closed outlet gap (s) is formed at an end of the flow channel of the nozzle and the core. The housing has a recess at its end. An angle (W) between the housing and the nozzle, and a tube head length (L) are changed such that the cross-section of the outlet gap is modified. An independent claim is included for a method for discharging a molten tube for the manufacturing of capillaries, tubes or pipes. |
