ABSTRACT:
A stranding machine including a plurality of reels on which filament to be stranded is wound; a separate, rpm-controllable motor connected with each reel; rpm control devices connected to each reel motor for controlling the reel rpm with respect to the stranding speed to determine the tension of the filament running from the reel; a separate compensating roller associated with each reel; and a separate support component carrying a respective compensating roller and being displaceable in opposite first and second directions. Each support component is coupled to the respective rpm control means for controlling the rpm of the respective reel drive motor as a function of displacement of the support component. The filament, as it runs about the compensating roller, exerts a force on the support component in the first direction. A force exerting assembly is connected with each support component for exerting a force on the support component in the second direction. The force exerting assembly has an electromagnetic slip clutch whose rotor is connected with a drive motor and whose armature is connected with the compensating arm and further, a device is provided to control the current supply to the stator of the slip clutch.
