Abstract
A device and method for unwinding or winding a sawing wire from a reel or to a reel which rotates. The sawing wire runs from the reel or toward the reel over a pulley and in so doing, assumes a defined axial position on the reel. In the method, the reel is moved along its rotational shaft while the sawing wire is unwound or wound up. The sawing wire however remains aligned perpendicular to the rotational shaft of the reel in the region between the reel and the pulley. There is a pivot arm which is moved concomitantly by a carriage system. The pivot arm has an end piece connected to one of the clamping elements. Thus it is possible to move the pivot arm from a reel-holding position into a reel-release position.
