Abstract
An apparatus for scoring a glass sheet includes a scoring wheel rotatably mounted to one end of a shaft mounted in a rod end ball joint and a spring acting on the other end of the shaft to urge the wheel toward a sheet movement path under a predetermined force. The glass sheet is advanced along the path under the scoring wheel to urge the scoring wheel against the biasing action of the spring. The axis of the scoring wheel is aligned in a plane normal and transverse to the movement path by the motion of the glass sheet as it advances under the scoring wheel.
