The present invention comprises a new glass bottle cutting device generally used for standard sizes bottles, with an adjustable length for up to 19.5-inch bottles. The device consists of a base, an L shaped backstop, rollers (wheels), and a carbide blade. When using it the blade scores the glass bottle so that you can split it into two parts with little effort.

An apparatus comprises a stressed glass member and an actuator mounted on the stressed glass member. A power source is coupled to the actuator. An abrasion structure is disposed between the actuator and the stressed glass member. The abrasion structure comprises abrading features in contact with the stressed glass member. The abrading features have a hardness higher than a hardness of the stressed glass member. When energized by the power source, the actuator is configured to induce movement of the abrasion structure that causes the abrading features to create scratches in the stressed glass member to a depth sufficient to initiate fracture of the stressed glass member.

A cutter edge is pressed against a brittle-material substrate so that a protruding portion of the cutter edge is positioned between a first edge of the brittle-material substrate and a side portion of the cutter edge and that a side portion of the cutter edge is positioned between the protruding portion of the cutter edge and a second edge of the brittle-material substrate. A scribe line is formed by a scratch between a first position closer to the first edge of the first and second edges and a second position closer to the second edge of the first and second edges. After the formation of the scribe line, a crack is extended in a thickness direction from the second position toward the first position along the scribe line, thus forming a crack line.

A method is provided for scoring glasses. The method includes the steps of generating a deep crack in the glass along an intended separation line by exerting pressure onto the glass surface using a rigid scoring tool, wherein the scoring tool, by being pressed against the glass surface and due to the advancement force while introducing the deep crack generates a zone of elastic strain in the glass in a direction along the glass surface and perpendicular to the separation line, which extends in an arc in the plane defined by the separation line perpendicular to the glass surface such that one leg of the arc is located close to the contact point of the scoring tool on the glass surface and another leg is located inside the glass. The arc being open towards the advancement/advancement direction of the scoring tool.

A method is provided for aligning scoring tools and for scoring glass, in particular thin glass, along predetermined scoring lines in preparation for breaking along the score. Glass substrates, in particular thin glass substrates, produced by such method are also provided. The method includes the determination of the actual orientation of the cutting edge of the scoring tool and aligning of the cutting edge to a target orientation of the cutting edge.

The invention discloses a protective glass cutting machine, including a cutting body, a cutting cavity is arranged in the cutting body, a conveying device is arranged in the cutting cavity, and the conveying device comprises a vertically symmetric conveying The rotating wheel, the opposite direction of the conveying wheel can drive the glass tube to move to the left for cutting. The invention rotates along the glass tube by the heated cutting knife, and the glass tube is quickly cut, and the glass tube is cut. The left and right sides are respectively provided with an output device and a conveying device to ensure the stability of the glass tube and improve the stability of the glass tube cutting. Secondly, when the glass tube is input to the left, the cutting knife and the glass tube are not abutted by the telescopic device.

Provided are a device for press-cutting glass, a method for press-cutting glass, and a glass-cutting system having the device for press-cutting glass. The device for press-cutting glass comprises a supporting member, having a first supporting portion and a second supporting portion for supporting a glass substrate, which are arranged in a spaced apart manner in a first direction; and a press-cutting member for press-cutting an edge of the glass substrate, which is positioned between the first supporting portion and the second supporting portion in the first direction. The device for press-cutting glass has advantages including high press-cutting efficiency, simple structure, low manufacturing cost, and easy assembling with other devices.

A sprayer device to be mounted on the top of a powered vehicle glass extractor gun, for emitting fluid upon actuation to a vehicle glass work site and to a blade mounted in the glass extractor gun, said device having a main body with a retainer front foot there beneath at the distal end, and with a lubricant storage compartment, fluidly connected to a rechargeable battery operated pump, which pump is connected to an input hose from the lubricant storage compartment and the pump is also connected to a second hose extending through the distal end of said body, said second hose having a blade holder thereon, through which a blade for the extractor gun is disposed such that when the device is actuated by an actuator, fluid is sprayed on the extractor gull blade and the work site.

An apparatus comprises a stressed glass member and an actuator mounted on the stressed glass member. A power source is coupled to the actuator. An abrasion structure is disposed between the actuator and the stressed glass member. The abrasion structure comprises abrading features in contact with the stressed glass member. The abrading features have a hardness higher than a hardness of the stressed glass member. When energized by the power source, the actuator is configured to induce movement of the abrasion structure that causes the abrading features to create scratches in the stressed glass member to a depth sufficient to initiate fracture of the stressed glass member.

A glass manufacturing apparatus may be configured to facilitate a process of separating a glass ribbon along a separation path extending across a width of the glass ribbon. In one example, the glass manufacturing apparatus comprises at least one anvil-side vacuum port defined by an elongated nose and an elongated anvil member. The anvil-side vacuum port is configured to remove glass debris during the process of separating the glass ribbon. In another example, the glass manufacturing apparatus comprises a scoring device and a score-side vacuum port configured to remove glass debris generated during the process of separating the glass ribbon.
