Abstract
Official abstract text for this publication.
The invention relates to an apparatus and to a method for the industrial production of elastically deformable large-surface-area glass plates in high quantities, comprising the following characteristics: a) a device for feeding a glass plate ( 3 ), b) a device for providing the surface of the glass plate ( 3 ) with initial damage in the region of the desired breaking line, c) a device for the locally limited heating of the glass surface by way of a laser beam moving on a straight line in a fan-shaped pivoting manner, d) a device for cooling the glass surface, wherein a controllable cooling nozzle delivering a fluid is disposed on at least one side of the laser beam, e) a device for transporting a thermally locally pretreated glass plate ( 3 ) into the region of a device for breaking the glass plate ( 3 ), f) a device for detecting a straight-line crack formation on the surface of a glass plate ( 3 ), g) a straight-lined breaking blade on the underside of the glass plate ( 3 ), which blade can be lifted on one side and/or both sides.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus for the industrial production of elastically deformable large-area glass plates in high quantities, comprising: a) a device for feeding a glass plate ( 3 ), b) a device for making an initial score on the top side of the glass plate ( 3 ) in the region of the desired breaking line, c) a device for the locally limited heating of the glass surface with a laser beam, d) a device for cooling the glass surface, wherein on at least one side…
