Abstract:
A method for unwinding a sawing wire from a reel or winding a sawing wire onto said reel, said reel having a rotational shaft, comprisingrotating the reel;running said sawing wire from the reel or toward the reel over a pulley so that the sawing wire adopts a defined axial position on the reel;moving the reel along said rotational shaft, rather than moving said pulley, and winding or unwinding the sawing wire so that the sawing wire remains aligned perpendicular to the rotational shaft of the reel in a region between the reel and the pulley, so as to avoid lateral deflection of the sawing wire;providing a sensor for detecting a movement in the axial position of the sawing wire;during unwinding of the sawing wire from the reel causing the sensor to execute a pivoting movement corresponding to the axial movement of the sawing wire; andduring winding of the sawing wire onto the reel blocking a pivoting movement of the sensor.
