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

The subject invention is directed to a device and method for removing an article attached to a mounting surface by an adhesive mounting. Preferably, the device comprises a first grip, a second grip and a filament having a first end attached to the first grip and a second end attached to the second grip. The filament operates such that when placed between the mounting surface and the adhesive mounting and pulled by the first and second grip in a direction along a bonding plane, it operates to separate the adhesive mounting from the mounting surface.

A method for removing a glazing panel bonded to a frame by an interposed bonding material, the method utilizing a flexible cutting line and has a set up phase resulting in the line being looped around substantially the entire the periphery of the glazing panel with opposed end portions of the line being secured on separate winder spools. In a cut out phase, the line is wound on to one of the winder spools while simultaneously being wound off the other of the winder spools.

A cutting mechanism (30) for a safety belt (10), the cutting mechanism (30) including a case (32), a passage (34) running through the case and making it possible to mount the cutting mechanism (30) on the belt (10) to be cut, and cutting elements (42) for the seatbelt (10), situated inside the case, the cutting elements (42) include a wire (44) and elements for heating (46) the wire. A process for cutting a safety belt (10), includes using a wire (44) and elements for heating (46) the wire in order to cut the belt with the heated wire.

A diamond wire saw and method provides a frame that includes a clamp that attaches to a target (e.g. piling, beam, tubular), an elongated toothed rack extending away from the mount and target, and a moving portion that carries the diamond wire and motor drives that advance the moving portion toward the target and along the toothed rack while driving the wire around roller guides.

A machine and method for making bags is described and includes a web, traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have, connected thereto, a source of power that is at an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire may be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones may include temperature zones, cartridge heaters, cooling air, or heated air, or a source of ultrasonic, microwave or radiative energy.

A method for slicing a workpiece into wafers by imparting axial reciprocating motion to a wire wound around a plurality of grooved rollers, and moving the workpiece relatively downwardly to press the workpiece against the reciprocating wire and feed the workpiece with the workpiece cut into while supplying a slurry to the wire, the method including the steps of: configuring each of the grooved rollers such that a distance from a bottom of grooves of the grooved roller to a rotating shaft of the grooved roller decreases gradually from a wire-supply side toward a wire-collection side; slicing the workpiece in such a manner that the workpiece is pressed against the wire on the wire-supply side before the workpiece is pressed against the wire on the wire-collection side.

A system, a method and a modular apparatus may use a wire loop to cut an object. The apparatus may have a wire loop connected to pulleys on a deck attached to a frame. The deck may move relative to the frame to direct the wire loop through the object. The apparatus may have arms that may hold the object being cut. The apparatus may be configured with different cutting decks to reduce the overall size of the apparatus and/or to facilitate cutting a particular object in a particular environment.
