  • Patent number: 11795096
    Abstract: Method and apparatus for removing a peripheral portion of a glass sheet. The glass sheet is placed in a predetermined position. A score line is formed on a major surface of the glass sheet. The score line demarcates a central region and a peripheral portion. A push bar is moved in a direction of a back-up bar assembly such to contact the major surface along the peripheral portion. The push bar is further moved in the direction to cause the peripheral portion to separate from the central region, and then become captured between the push bar and the back-up bar assembly. With some embodiments, the glass sheet is vertically oriented and the peripheral portion is not constrained during formation of the score line.

  • Patent number: 11780760
    Abstract: Systems and methods for automated, sequential processing of a continuous glass ribbon by conveying the glass ribbon in a ribbon travel direction, forming a score line in the glass ribbon, separating a glass sheet from the glass ribbon at the score line while supporting the glass sheet with a transfer device, lowering the glass sheet onto a conveyor, and conveying the glass sheet in a sheet travel direction differing from the ribbon travel direction. By transferring and then conveying the glass sheet in a direction differing from the ribbon travel direction (e.g., a 90 degree turn) immediately after glass sheet separation, the systems and method of the present disclosure are conducive to streamlined production of glass sheets utilizing a unique production floor footprint.
