ABSTRACT:
In a wire saw drive apparatus having a carriage, a wire drive pulley mounted on the carriage, pulley drive means for rotating the wire drive pulley to drive an endless cutting wire, a pair of adjust pulleys for guiding a tensile side and a loose side of the cutting wire, and carriage drive means for moving the carriage and maintaining the cutting wire under a desired tension, the improvement comprises elastic means mounted between an adjust pulley supporting body for guiding at least the tensile side of the cutting wire and the carriage, for receiving a force applied from the cutting wire to the adjust pulley, and a guide pulley mounted on the carriage near the adjust pulley for guiding the tensile side of the cutting wire, for guiding the cutting wire into S shape fashion in cooperation with the adjust pulley.
The elastic means instantaneously absorbs an instantaneous increase in cutting wire tension through the adjust pulley, and suppresses cutting wire damage or breakage and cutting wire slip relative to the wire drive pulley. The guide pulley serves to allow the above elastic means to function stably and effectively.
