Patent ID: 8434468

Claim:
A wire saw apparatus, comprising: a wire which is wound around a plurality of grooved rollers and axially travels in a reciprocating direction; a nozzle for supplying a slurry to the wire; and a work-feeding mechanism which feeds a work to be sliced towards the wire by holding and pushing down the work, and causes the work to be sliced into wafers by pressing and feeding the work held by the work-feeding mechanism against the wire while a slurry is supplied to the wire through the nozzle, a work-holding portion of the work-feeding mechanism holding the work through a pad plate adhered to the work to be sliced and a work plate holding the pad plate; and plate-shaped or block-shaped slurry-splash-blocking members for blocking the slurry splashing from a wire cut-in side of the work that are arranged in the direction of a right angle to a row of the wire wound around the grooved rollers below the work-holding portion and on both the wire cut-in side and a wire cut-out side, a lower end of the slurry-splash-blocking members being placed below the work plate, and a lower surface of the slurry-splash-blocking members being tapered toward its outside.
