A device for forming a separation starting point that allows separation of a surface layer of a processed member to form a remaining portion is provided. A manufacturing device of a stack including a support and a remaining portion of a processed member whose surface layer is separated is provided. The device for forming the separation starting point includes a stage that supports the processed member, a cutter that faces the stage, a head portion that supports the cutter, an arm portion that supports the head portion, and a moving mechanism that relatively moves the cutter to the stage.

Apparatus for manufacturing glass including a forming body configured to form a glass ribbon and a glass scoring apparatus positioned below the forming body. The glass scoring apparatus includes a frame, a cross-member assembly and a movable scoring unit coupled thereto. At least four drive assemblies are mounted on the frame, each drive assembly including a threaded shaft, a drive motor coupled to the threaded shaft and configured to rotate the threaded shaft, and a ball nut assembly engaged with threads of the threaded shaft and coupled to the cross-member assembly such that rotation of the threaded shafts by the drive motors causes the cross-member assembly to vertically rise or lower. Multiple scoring devices are provided to enable bidirectional scoring of the glass ribbon.

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.

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.
