The present invention relates to a blade for a cutting tool of a ceramic cutting machine that improves the stability and quality of the cut made on ceramic tiles by means of said cutting machines, due to its specific geometric features. Said cutting tools of ceramic cutting machines are commonly known as “scoring wheels” and the blade they comprise is commonly known as “scoring blade”.The invention is applicable to the field of the metal tool manufacturing industry and the handling ceramic material industry.Current ceramic cutting machines that are manually operated typically comprise a bench where the tile or ceramic piece to be cut is placed, a positioning element of said tile in the bench, and a sliding lever that slides on rails, having a tool carrier element in which a cutting tool (or “scoring wheel”) is inserted, which is in turn formed by a handle and a disc-shaped blade (or “scoring blade”). By means of the pressure exerted by the lever, a certain pressure is exerted by the scoring wheel on the tile to be cut. While exerting said pressure, and by advancing the lever with its tool carrier along the rails, a cut is progressively made on the tile.In ...

A glass cutter is provided which can form, using a wheel, a uniform crack in glass even when a projection or an earlier-formed scribe line is present on the glass. When the wheel is moved on the glass, a fracture layer is formed causing a rib mark to be formed below the fracture layer and a crack to be formed below the rib mark. To cut the glass, the crack is required to be formed uniformly. Applying a force to resist the rotating force of the wheel makes it possible to form a uniform crack even when a projection is present on the glass. This improves glass cutting yield. 1.

Embodiments simultaneously separate dies in two dimensions by utilizing a break and expansion system that avoids die collisions by maintaining IC die separation after singulation. Singulation is achieved by placing the joined dies of the wafer substrate on a dicing tape, scoring the wafer substrate between the joined dies, and imposing a bending action by pressing a curved surface against the scored wafer substrate, which also expands the wafer substrate by stretching the dicing tape. After breaking, an inner expansion grip ring is pressed into an outer expansion grip ring in a nested configuration so as to maintain the stretched state of the dicing tape after the curved surface is fully removed, thereby maintaining the dicing tape in tension and the singulated die in spaced apart relation. 1.

In further examples, a glass web separation apparatus includes a first reflector that rotates such that a laser beam spot repeatedly passes along a separation path and a second reflector that rotates such that the laser beam spot moves in a conveyance direction of the glass web. 1. A method of separating a glass web comprising the steps of:(I) moving the glass web at a glass web velocity including a glass web velocity vector in a conveyance direction of the moving glass web;(II) exposing a separation path on the glass web to at least one laser beam spot to produce thermal stress along the separation path, the separation path extending in a direction transverse to the conveyance direction;(III) moving the laser beam spot at a laser beam spot velocity including a laser beam spot velocity vector in the conveyance direction that is equal to the glass web velocity vector, wherein the separation path continues to be exposed to the laser beam spot to continue producing thermal stress along the separation path while the glass web moves at the glass web velocity; and(IV) creating a defect on the separation path while the separation path is under thermal stress produced during steps (II) and (III), whereupon the glass web separates along the separation path in response to creating the defect.2. The method of claim 1 , wherein step (III) includes reflecting at least one laser beam off a rotating reflective surface to cause the laser beam spot to move ...

A device for removing shingles having a fork tool and a handle adapted to fit into an air-powered hammer. The fork tool features teeth and has two ends that are joined at an angle. Each tooth has a square-shaped head and a body that extends away from the head of the tooth at an angle. The teeth extend up and away from the fork tool at an angle. The fork tool is removably attached to the handle. In operation, the power tool forces the tool forward under the shingles and the angle of the teeth lifts the shingles slightly off the surface of the roof and the leading edge and the trailing edge of the fork tool forces the shingle upward. The device features a back plate also attached to the handle that has a ridge along its lateral surface that can be used as a fulcrum. 1.
