Abstract: A method for separating a thin glass, in which method the thin glass is progressively heated along a path which forms a parting line, wherein the heating of the glass is realized by way of the energy of at least one energy source within an area of action of the energy source on the thin glass, and, by way of a temperature gradient of the glass heated by way of the at least one energy source in relation to the surrounding glass, a mechanical stress is generated in the glass, by way of which mechanical stress, a crack propagates, following the mechanical stress, along the parting line.

Abstract: An improved method and an improved apparatus are provided for producing a thin glass ribbon, which provide borders at the edges of the ribbon. The edges formed are of high mechanical quality and a formation of new secondary borders after the severing or at least the thickness of such secondary borders is reduced compared to the original borders. The method includes drawing the thin glass ribbon from a molten glass or from a preform, severing the borders, and cooling the resulting glass ribbon. The severing is effected at a location along the moving direction of the thin glass ribbon and at a time at which during the cooling of the thin glass ribbon the viscosity of the glass is in a range from 107 dPa·s to 1011 dPa·s, so that the edges of the thin glass ribbon newly produced by the severing of the borders are rounded off.

Abstract: A method for producing thing glass strips is provided that avoids camber defects. The method includes using a glass strip forming device that has a drawing device; drawing, using the drawing device, the thin glass strip away from the glass strip forming device; measuring, using a measuring device, variables that are dependent on a differing length of edges of the thin glass strip at at least two measurement locations spaced apart transversely to a longitudinal extension of the thin glass strip; determining a difference or a quotient of the variables. The difference or the quotient is used to determine a control variable by which the glass strip forming device is controlled so as to counteract a difference in velocities of the thin glass strip between the two opposite edges.

Abstract: A method for cutting a thin glass including the steps of guiding, by a transport device, the thin glass ribbon over a levitation support, and directing, within a range of the levitation support, a laser beam onto the thin glass ribbon, which heats up the thin glass ribbon at an impingement point of the laser beam. The method also includes the step of blowing, by a cooling jet generator, a cooling fluid onto the track heated by the laser beam so that a region heated by the laser beam is cooled down and a mechanical stress is created. The cooling fluid contains vapor of a liquid at a saturation ratio of at least 0.5 or a plurality of liquid droplets. The liquid droplets form a contact angle on a surface of the thin glass ribbon which is smaller than that of water on the same surface.

Abstract: A method for testing the strength of a sheet-like element having two opposite faces and made of hard brittle material under tensile stress is provided. The method includes passing each of the faces of the element over a roller and thereby bending the element so that each of the faces is subjected to a first tensile stress in a portion in which the opposite face is in contact with a surface of the roller; exerting a second tensile force on the element in the direction of advancement so that both faces are subjected to the second tensile stress of at least 2 MPa so that the first and second tensile stresses add up to define a resultant tensile stress; and monitoring the element and determining whether the element has a defined breaking strength equal to the resultant tensile stress or whether the element breaks under the resultant tensile stress.
