The system may also include a glass sheet part identifier and a programmable control including logic for analyzing acquired image data and selecting an area of interest on the glass sheet for the analysis.

HIGH TEMPERATURE HIGH LOAD COMPATIBLE BEARING
20190024704 · 2019-01-24 ·

A high load, high temperature compatible bearing assembly (200) includes a shaft (208) formed of refractory steel or high temperature alloy. A roller (204) formed of refractory steel or high temperature alloy receives the shaft (208) within a bore (220) in the roller (204). At least one bearing ring (212) formed of ceramic is disposed between the shaft (208) and the roller (204). The bearing ring (212) cooperates with the roller (204) to permit the roller (204) to freely rotate around the shaft (208).

DEVICE FOR BENDING SHEETS OF GLASS
20180362386 · 2018-12-20 ·

A device for bending sheets of glass, includes conveying rollers that convey the sheets one after another in a longitudinal direction, carrying them under an upper bending die and onto a receiving surface formed by the upper level of the rollers under the die. The device includes an intermediate support including a contact path for supporting the sheet of glass to be pressed lying under the die. The contact path has, parallel to the edge of the sheet to be pressed, a curvature that is less accentuated than the curvature that is to be imparted by the upper die. The intermediate support can rise above the receiving surface and support the sheet to be pressed until the sheet breaks contact with the rollers. The intermediate support can be lowered down below the receiving surface. A sheet-pressing system can press the periphery of the sheet against the upper bending die.

VACUUM MOLD SHUTTLE SYSTEM FOR A GLASS SHEET FORMING SYSTEM

A vacuum mold shuttle system in a glass sheet forming system includes a vacuum mold mounted on a support frame. A shuttle frame including a pair of generally parallel elongate beams for receiving and supporting the mold support frame thereon. A vacuum source is mounted on the shuttle frame near the end of the beams opposite to the end supporting the mold, a conduit and coupling port for releasably connecting the mold to the vacuum source. At least one guide element is mounted on the support surface of one of the beams for receiving and fixing the position of the mold support frame relative to the shuttle frame to align and prevent movement of the mold support frame with respect to the shuttle frame in any direction as the mold support frame is supported thereon.
