  • Patent number: 12686953
    Abstract: A thread production system has a workstation with, in each case one after another on a processing path, a melt-spinning device with multiple melt nozzles, a thread inlet section, an inlet godet roller pair located at the end of a thread inlet section, a thread drawing device with two hot godet roller pairs which are arranged on a drawing panel frame of the thread production system, and a one take-up reel. The free godet roller ends of a first hot godet roller pair of the thread drawing device on the processing path protrude into an identical first half space as free godet roller ends of the inlet godet roller pair. Here, a rotational axis of a first godet roller of the inlet godet roller pair on the processing path is oriented at an angle of from 0° to 45° with respect to the longitudinal orientation of the nozzle row.
