Claims (6)

1 2 serve the one even train on the patent claims: guaranteed to be wound. It is also based on the German disclosure document 1 538 485 1. Drive arrangement for a winder knows to adjust this train according to the design data of the strand-like, to be stranded goods with S goods and to unite it from position to position, controllable in its torque, strengthen in order to ask the fact into account , the same as the laying device and the fact that, with increasing number of layers of the lever, the DC motor driving the drum and which the opposing force acts on, becomes larger and larger. In which the rewinder of another one from the German Auslegeschrift 1 510088 was operating by one. Axis can be rotated, the io known drive arrangement of a stranding machine, perpendicular to the axis of the to be wound, which all in the upper area of the main claim has enttrommel and parattel to the axis of the arriving features, rotates the winding strand strand-shaped goods, thereby device in operation an axis that is marked on the that the DC axis of the coil or drum to be wound gate (2) depending on the distance of the laying 15 is perpendicular, and in this embodiment, the device (6) serves from its central position in the DC motor at the same time as a drive for one or more stages or continuously for the winder and for the laying device. With changing, a stronger current is supplied to the latter devices than that which occurs when the difficulty arises that the laying device is in its central position on its laying device in constantly changing degrees of centrifugal forces. is set by the driving direct current 2. Drive arrangement according to claim 1, since the motor must be overcome. Since the Motoi characterized in that the degree of current but current-controlled, brings a higher effort Change due to the speed of rotation around the axis necessary for overcoming the centrifugal force to the drum (4) rotating winding »5 way a reduction of the tensile force with it. this lers is determined. leads z.

Drive arrangement according to one of the adapters, goods to be stranded with one in his Claims 1 to 3, characterized in that controllable torque, at the same time the laying front DC motor (2) in the end positions and driving the drum to be wound the laying device (6) specify a predetermined 35 DC motor, the winder Current can be supplied, which when approaching another drive in operation by one Laying device (6) can be rotated to its central position in the axis perpendicular to the one or more stages or continuous axis of the drum to be wound and parallel can be reduced. to the axis of the incoming rope-like goods 5. Drive arrangement according to claim 4 with 40 runs. a reduction of the current in one stage, This object is achieved according to the invention with the characterized in that the laying device advantageous characteristic features of the treatment (6) is provided with a sensing strip (14), the main claim is solved. when passing through the middle position and The particular advantage of this drive is that if necessary for an additional one to see that the influence of centrifugal forces is at least A key switch can be switched off so far that it is the first (15) through which the reducible tolerance no longer has an obstructive effect, It is advantageous if the measure of the change in current is effected for such a long time how the pushbutton switch with the feeler strip is made dependent on the speed at which the (14) is in contact. 50 rewinder rotates around the axis that is perpendicular to the 6.
