A cutting apparatus includes a wire cutting member, a plurality of wheels about which the wire cutting member is at least partially wrapped, a first arm member supporting at least one of the plurality of wheels, and a second arm member supporting at least one of the plurality of wheels. The first arm member and the second arm member may be moveable between a first position, in which the cutting apparatus has a first size, and a second position, in which the cutting apparatus has a second size larger than the first size. A wire saw includes an adjustment member coupled to at least one of a plurality of wheels for moving the at least one of the plurality of wheels to adjust a tension of a wire cutting member. A wire saw includes a visual indicator for indicating an amount of tension applied to a wire cutting member.

A wire saw for cutting pipe is provided including a saddle forming a saddle surface for abutting against a cylindrical pipe, an elongate guide fixed to the saddle, a bow having a first and second end, a bridge portion joining the first and second ends, and an open end having a length L from the first end to the second end which is greater than a diameter D of the pipe, a wire loop movable along a track formed within the bow, and a cooling system for actively cooling the wire loop. The elongate guide has an axis approximately perpendicular to an axis of the pipe when the pipe is abutting against the saddle. An exposed portion of the wire loop extends across the open end. The bow is moveable on the elongate guide toward and away from the pipe when the pipe is abutting against the saddle.

A winder unit is provided for use with cutting wire in cutting out a vehicle glazing panel. The winder unit includes first and second winder spools spaced apart from one another, where the winder spools are configured to wind the cutting wire. The winder unit further includes a suction mount for mounting the winder unit, wherein the suction mount comprises a single suction device only. And the winder unit further includes at least one wire guide element spaced from the winder spools, wherein the at least one wire guide element is mounted with respect to the winder unit so as to be adjustable in position or orientation with respect to at least one of the suction mount and the winder spools.

A cutting apparatus includes a main roller, a main motor configured to rotate the main roller, a plurality of adjusting rollers spaced apart from the main roller, a plurality of sub-motors respectively connected to the plurality of adjusting rollers and configured to respectively rotate the plurality of adjusting rollers, a plurality of cutting wires wound around the main roller and the plurality of adjusting rollers, and a controller configured to control the main motor and the plurality of sub-motors such that a surface speed of the main roller is substantially the same as surface speeds of the plurality of adjusting rollers.
