Abstract
A wire-unwinding device in which wire can be unwound from a very large wire drum such that the direction of curvature of the wire is maintained and alternating bendings of the wire are avoided. The wire is guided over a stationary first guide pulley, a second guide pulley, which is changeable in position in order to apply an initial tensioning force, and over a further stationary third guide pulley.
