Abstract: PURPOSE:To provide the subject heat-treating unit capable of freely shifting the heating zone in the vertical direction in a state where the heat-treating unit is fixed and of also freely selecting the heating zone length in producing fibers different, e.g. in the single yarn fineness, the kind of polymer and the take-off speed. CONSTITUTION:In a filament heat-treating unit comprising at least a heating cylinder and designed so as to heat the atmosphere of a high-speed span filament cooled and coagulated once, this heat-treating unit for high speed spinning is characterized by heat-insulating cylinders 3 and 4 detachably installed on one or both ends of the inner peripheral surface of the heating cylinder 1. According to the kind of fiber, the distance from the nozzle to the heating zone can be changed in a state where the heat-treating unit is fixed. Various kinds of fibers, therefore, can be produced by the same spinning machine in a state where the heat-treating unit is fixed. Consequently, the faults in the conventional technique, i.e., problems, e.g. about extension of a new device for shifting the heat-treating unit, control of the thread handling area and accuracy of setting of the heat-treating unit can be solved.
