The present invention relates to a cutting method and a cutting device for the superficial scoring of, preferably plate-shaped, components made of glass or ceramics, preferably of glass sheets, and to a method for dividing of, preferably plate-shaped, components made of glass or ceramics, preferably of glass sheets, for example of float glass sheets or laminated glass sheets, in particular laminated safety glass sheets, into individual component cuttings, preferably glass sheet cuttings.

A glass plate bend-breaking machine for a glass plate includes a supporting mechanism by which a glass plate with a predetermined bend-breaking line as a cut line formed on an upper surface, i.e., one surface, thereof is supported at a lower surface, i.e., another surface, of the glass plate; and press-breaking devices and for press-breaking the glass plate along the predetermined bend-breaking line. Each of the press-breaking devices has a pressing body for simultaneously pressing a plurality of parts and along the predetermined bend-breaking line on the upper surface of the glass plate at the time of press-breaking the glass plate along the predetermined bend-breaking line at each of press-breaking positions on the glass plate.

An automated glass scoring device and a pillar post are provided. The pillar post includes a body having a fluid inlet port, at least one internal passage, a fluid exit port, and a fluid flow metering element. At least a portion of the fluid flow metering element is disposed within the internal passage. The at least one internal passage provides a path for a fluid flow from the inlet port to the fluid exit port, and the fluid exit port is positioned such that the fluid flow exiting the fluid exit port exits in close proximity to the cutter wheel.

The present invention concerns a device (1) for cutting a plate (70) of a pre-determined thickness, preferably a glass plate. The device foresees: —A frame (10, 31); —A support device (12, 20) for a cutting utensil connected to the frame. In accordance with the invention, the support device (12, 20) is mobile according to an extraction/retraction motion with respect to the frame (10). Further, a hinged lever system (32, 33, 34) is further foreseen, having a feeler element (50), said hinged lever system being kinematically coupable with said support device (12, 20) in such a way as to bind it in a pre-determined initial position with respect to the frame and so that, when said feeler element is pressed against a surface (70), an operation of the hinged lever system is determined which conducts the support device, starting from said initial position, to an extraction motion.

Electrochromic device laminates and their method of manufacture are disclosed.

The invention discloses a liquid crystal screen glass cutting method and apparatus to solve the unhealthy problem of being broken or serrated to be produced for the liquid crystal screen glass at intersections of cutting marks in different directions in the cutting procedure. This liquid crystal screen glass cutting method comprises: a cutter wheel cutting a first surface of the liquid crystal screen glass along a first direction for the first time to form first cutting marks on the liquid crystal screen glass; and after the completion of the first-time cutting, the cutter wheel cutting the first surface of the liquid crystal screen glass along a second direction for the second time, wherein when the distance from a first cutting mark equals a cutter-out distance, the cutter wheel rises a jump height perpendicularly to the liquid crystal screen glass and keeping the jump height, travels a stroke along the second direction which is a sum of the cutter-out distance and a cutter-in distance, then descends perpendicularly to the liquid crystal screen glass to the liquid crystal screen glass and continues to cut the liquid crystal screen glass along the second direction, until second cutting marks are formed on the first surface, wherein the second direction is perpendicular to the first direction.

Apparatus and method for producing a reliable breaking line for the industrial cutting to length of glass sheets by means of a cutting wheel running on a float glass line under pressure imposed from above, with the following features: a) the location of the beginning of a breaking line is determined and a cutting wheel holder (20) with a cutting wheel (2) is brought into position, b) the cutting wheel holder (20) is lowered and the cutting wheel (2) is lowered onto the glass sheet (1) concerned with the desired pressing pressure, wherein the pressing pressure is set by means of a swing arm (3) and is monitored by means of a strain gauge (4) secured thereto, c) a change in the height of the glass sheet (1) prompts a control signal for an actuating motor (12) to be derived from the change in the resistance of the strain gauge (4), and the actuating motor brings about a corresponding change in the pressing pressure of the cutting wheel (2).
