摘要

Grippers of a cutting wire moving and positioning system connect with guide members holding the wire ends. Guide members comprise parallel guide rails (4) on opposing shanks of the cutting frame (1), current supply rails (5) parallel to the guide rails and wire holders (2) which move along the guide rails and are used to hold, tension, adjust and supply heating current to the cutting wires (6).
