ABSTRACT:
A glass scoring head has pressure rollers which engage the glass on either side of the scoring wheel to compensate for variations of flatness in the glass, and the scoring wheel is pendulously supported so that it can score in one and an opposite direction without moving the head on the associated bridge structure. The means for so supporting the scoring wheel also includes novel means for rotating the pendulum support itself to permit scoring in mutually perpendicular directions, both of which directions are also reversible as a result of the pendulous mount.
