Abstract: A straightening and cutting-off machine for the production of straightened elements of predeterminable length from a wire-shaped material, in particular for the production of straightened bars from reinforced-concrete steel wire, has a feed device for drawing in material from a material stock, a preferably rotating straightening device for straightening the material conveyed into a working range of the straightening device by the feed device, a cutting device, following the straightening device, for separating a portion of predeterminable length from the straightened material to produce the straightened element, a length measurement system for measuring the length of the material and for generating a measurement signal representing the length, and a control device for activating the cutting device on the basis of the measurement signal.

Abstract: Separate three-phase windings are connected to individual rectifiers arranged for series-parallel switching to improve the current-voltage output characteristic. The common exciter winding is fed through a voltage regulator. The switching of the rectifiers is controllable in response to alternator frequency, output current, temperature or efficiency and may be provided with a manual override switch.
