WIRE SAW DEVICE AND METHOD FOR OPERATING SAME

摘要

A wire management unit adapted for a wire saw device (200; 300; 400; 500) having a wire (213) forming a wire web for cutting is described. The wire management unit includes a pulley moving device (240; 440); at least one pulley (220; 520) for redirecting the wire and adapted for guiding the wire to the wire web, wherein the at least one pulley is connected to the pulley moving device and is adapted to rotate around a pulley axis; a spool (212) for providing a wire towards the wire web during unwinding of the wire from the spool, wherein the spool includes a rotation axis (212a) and a wire carrying area (213a) with a length along the direction of the rotational axis; and wherein the pulley moving device is adapted to move the at least one pulley along the direction of the rotation axis.
