ABSTRACT:
The head compensates for variations in flatness of a table upon which a glass sheet is placed for scoring, and also compensates for bending of the rails or support structure which carry the head as it traverses the table. A jump wheel is provided on a first arm pivotally mounted in the head, which head may comprise a trolley structure, and a scoring tool is mounted in a pivoted second arm having its pivot on the first arm. A spring acts between the first and second arms to bias the scoring tool to a limit position, defined by a suitable stop, such that the force of the scoring tool on the surface of the glass is independent of vertical displacement of the scoring tool as it traverses the sheet. The first arm is also spring biased to maintain contact between the jump wheel and the glass surface. The head can be used by itself on a suitable support or bridge structure for scoring the glass in one direction, or it can be mounted in a carriage for movement of several such heads in a direction longitudinally of the glass sheet.
