A glass sheet processing apparatus includes a glass sheet processing station including a laser cutting assembly that includes an optical arrangement positioned in a beam path of the laser providing a laser beam focal line that is formed on a beam output side of the optical arrangement. A glass holding conveyor belt carries a glass sheet by the laser cutting assembly so that the laser beam focal line is positioned on the glass sheet with the glass sheet on the glass holding conveyor belt. The glass holding conveyor belt is configured to carry multiple glass sheets to the laser cutting assembly for cutting the multiple glass sheets on the glass holding conveyor belt in a repeated fashion.

A method for forming an initiation defect in a glass substrate to facilitate separating the glass substrate into a plurality of substrates is provided. The method includes providing the glass substrate and contacting a broad surface of the glass substrate with an abrasive surface thereby forming a field of initiation defects in the broad surface of the glass substrate. The field of initiation defects has a width of at least about three millimetres between outermost initiation defects. At least one initiation defect is heated with a laser source. The at least one initiation defect is cooled with a cooling fluid such that a crack initiates from the at least one initiation defect, the crack extending through a thickness of the glass substrate and propagating across the glass substrate to separate the glass substrate into the plurality of substrates.

A machine for cutting flat glass sheets has a fixed frame for supporting a worktable, which can be lifted, with rotation device, for loading and unloading sheets or sheet portions, and a movable bridge capable of performing a translational motion with respect to the worktable which supports a cutting head capable of moving on the bridge. The movable bridge slides on rails associated with a fixed frame and the rotation device for the liftable worktable has at least one lifting arm, which is fixed to the movable worktable and pivoted to the fixed frame, the lifting arm being contoured so as to extend around and not affect, during its rotation, the rails for the movable bridge, a portion of the rails extending so as to affect the region of rotation of the lifting arm.

A method and apparatus for forming vents (13) in glass sheets (10). The method includes repetitively performing the steps of: (I) bringing a score head (21) and a platen (31) into contact with, respectively, the front (11) and rear (12) major surfaces of the glass sheet (10), (II) moving the score head (21) across the front major surface (11) along a predetermined path to form a vent (13), and (III) withdrawing the score head (21) and the platen (31) from the front (11) and rear (12) major surfaces, wherein: (i) the thickness (δ) of the glass sheet is less than or equal to 500 microns, and (ii) for each repetition of steps (I) through (III), the platen (31) is cleaned after step (III) and before step (I) to remove glass chips which if left on the platen (31) could cause the score head (21) to penetrate through the thickness δ.

A chip having a desired shape is formed from a platelike workpiece. The chip manufacturing method includes a shield tunnel forming step of applying a pulsed laser beam to the workpiece from a focusing unit included in a pulsed laser beam applying unit along the contour of the chip to be formed, with the focal point of the pulsed laser beam set at a predetermined depth from the upper surface of the workpiece, thereby forming a plurality of shield tunnels inside the workpiece along the contour of the chip to be formed. Each shield tunnel has a fine hole and an amorphous region formed around the fine hole for shielding the fine hole. In a chip forming step, ultrasonic vibration is applied to the workpiece to break the contour of the chip where the shield tunnels have been formed, thereby forming the chip from the workpiece.
