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.
