Abstract
An assembly is provided that includes a mineral-based monolithic support for full-surface supporting of a workpiece during processing and transportation and a workpiece supported thereon, wherein the surface of the support is designed so that adherence of the supported workpiece is prevented, and wherein the support has provisions with means inserted therein, which permit to lift the workpiece from the support from below and/or to shift the workpiece laterally, and furthermore relates to a mineral-based monolithic support suitable for this purpose.
Claims16
An assembly, comprising:
- a mineral-based monolithic support having a support surface;
- and
- a sheet-like workpiece made of a glass, glass ceramic, or ceramic element, the workpiece having a face fully resting on the support surface,
- wherein the workpiece exhibits at least one feature selected from the group consisting of a ratio of diameter or lateral dimension to an average thickness of at least 50, a ratio of diameter or lateral dimension to an average thickness of at least 100, a ratio of diameter or lateral dimension to an average thickness of at least 150, a ratio of diameter or lateral dimension to an average thickness of at least 200, and most a ratio of diameter or lateral dimension to an average thickness of at least 300, a ratio of basis weight to diameter of 100 kg/m3 or less, and a ratio of basis weight to diameter of 30 kg/m3 or less;
- a metal carrier, the support surface being is mounted on the metal carrier;
- and
- shock absorbers formed of metal wire or metal rope pads below the metal carrier.
A monolithic support, comprising a mineral-based carrier material having a surface configured for full-surface support of a face of a workpiece during processing and/or transportation, wherein the surface is configured so that adherence of the face to the surface is prevented, and wherein the full-surface support comprises supporting provisions, drainage channels that define segments in the surface, and coupling links that interconnect the supporting provisions and the drainage channels, the segments comprising an anti-adhesive coating, and the supporting provisions comprising at least one nozzle for conducting at least one fluid through the segments to the face of the workpiece so as to lift the workpiece from the face and/or to shift the workpiece laterally.
A monolithic support, comprising a mineral-based carrier material having a surface configured for full-surface support of a face of a workpiece during processing and/or transportation, wherein the surface is configured so that adherence of the face to the surface is prevented, and wherein the full-surface support comprises supporting provisions defined in the surface, the supporting provisions being configured to lift the workpiece from the face and/or being configured to shift the workpiece laterally, wherein the surface of the full-surface support comprises a periphery provided with an anti-adhesive coating, and wherein the anti-adhesive coating comprises a laminate of films.
A monolithic support, comprising a mineral-based carrier material having a surface configured for full-surface support of a face of a workpiece during processing and/or transportation, wherein the surface is configured so that adherence of the face to the surface is prevented, and wherein the full-surface support comprises supporting provisions defined in the surface, the supporting provisions being configured to lift the workpiece from the face and/or being configured to shift the workpiece laterally, wherein the surface of the full-surface support comprises an anti-adhesive coating in a form of one or more concentric rings, wherein the anti-adhesive coating comprises a film, and wherein the film is made of polyethylene or polypropylene.
A monolithic support, comprising a mineral-based carrier material having a surface configured for full-surface support of a face of a workpiece during processing and/or transportation, wherein the surface is configured so that adherence of the face to the surface is prevented, and wherein the full-surface support comprises supporting provisions and segments defined in the surface, the segments comprising an anti-adhesive coating, and the supporting provisions comprising at least one nozzle for conducting at least one fluid through the mineral-based carrier material to the face of the workpiece so as to lift the workpiece from the face and/or to shift the workpiece laterally,
- wherein the surface of the full-surface support comprises a periphery provided with an anti-adhesive coating,
- wherein the anti-adhesive coating comprises a film, and
- wherein the film has a thickness of at least 50 μm.
A monolithic support, comprising a mineral-based carrier material having a surface configured for full-surface support of a face of a workpiece during processing and/or transportation, wherein the surface is configured so that adherence of the face to the surface is prevented, and wherein the full-surface support comprises supporting provisions and segments defined in the surface, the segments comprising an anti-adhesive coating, and the supporting provisions comprising at least one nozzle for conducting at least one fluid through the mineral-based carrier material to the face of the workpiece so as to lift the workpiece from the face and/or to shift the workpiece laterally,
- wherein the surface of the full-surface support comprises a periphery provided with an anti-adhesive coating,
- wherein the anti-adhesive coating comprises a film, and
- wherein the film has a thickness of at least 65 μm.
A monolithic support, comprising a mineral-based carrier material having a surface configured for full-surface support of a face of a workpiece during processing and/or transportation, wherein the surface is configured so that adherence of the face to the surface is prevented, and wherein the full-surface support comprises supporting provisions defined in the surface, the supporting provisions being configured to lift the workpiece from the face and/or being configured to shift the workpiece laterally, wherein the full-surface support comprises web-like arrangement of drainage channels comprising radially extending and circular elements provided in the surface.
