摘要： Thin glass elements with improved edge strength are provided—from a sheet glass element that has two opposite parallel faces and an edge connecting the faces. The sheet glass element has a thickness of at most 700 μm. At least a portion of the edge is defined by an edge surface portion that is convexly curved, so that at least one of the faces merges into the edge surface portion, wherein a curved arc of the edge surface portion has a length that is at least 1/30 of the thickness of the sheet glass element. In the region of the convex curvature, the edge surface portion has indentations in the form of furrows.

摘要： A method and apparatus for scoring thin glass for the purpose of score and break separation as well as an accordingly prepared scored thin glass are provided. The scoring tool is pressed onto the thin glass and drawn along the scoring line with an adjusted scoring contact pressure force as a vertical scoring force component. This permits to production of prescored ultrathin glass of Knoop hardness from 350 to 650 with a score depth from 1/20 to ⅘ of the material thickness.

摘要： A device for cutting through workpieces of mechanically brittle and non-metallic material moving at a speed along a separation line after scoring is provided. The device includes a tool holder that is rotatable about an axis of rotation. The tool holder accommodates at least one cutting wire as a cutting tool to introduce a surface rupture or a crack into the workpiece. The cutting wire is disposed in the tool holder in such a manner that the surface rupture or the crack is introduced substantially perpendicular to a feed direction of the workpiece moving at a speed.

摘要： A method includes: providing a plate-like glass element having side faces and an ultrashort pulse laser having a laser beam; directing the laser beam onto one of the side faces; concentrating the laser beam by focusing optics to form an elongated focus in the glass element; producing a filament-shaped flaw in a volume of the glass element by a radiated-in energy of the laser beam, a longitudinal direction of which runs transverse to one of the side faces, and the ultrashort pulse laser radiates in a pulse or a pulse packet having at least two successive laser pulses to produce the filament-shaped flaw; widening the filament-shaped flaw to form a channel by exposing the glass element to an etching including an etching medium which removes glass at a rate of less than 8 μm per hour; and introducing rounded, hemispherical depressions in a wall of the channel by the etching.

摘要： A plate-like glass element including a pair of opposite side faces and at least one channel introduced into the glass of the glass element. The at least one channel joins the side faces and opens into the side faces. The at least one channel has a rounded wall and a transverse dimension of less than 100 μm. The at least one channel extends in a longitudinal direction that runs transverse to the side faces. The rounded wall of the at least one channel has a plurality of rounded, substantially hemispherical depressions.

摘要： A packaging unit for a glass wound on a winding shaft includes a transport unit with a mounting support for the winding core which has a transport unit interior part and a transport unit exterior part. The transport unit interior part includes a floor element and side elements. The transport unit exterior part includes a floor element, side elements and a cover element. The mounting support for the winding core is always connected with or formed by two side elements of the transport unit interior part which are located opposite each other. The transport unit interior part is spaced apart from the transport unit exterior part in a floor region by spring elements, so that the transport unit interior part is arranged vibration-decoupled from the transport unit exterior part. A method of utilizing a transport unit for packaging a glass that is wound on a winding core is also disclosed.
