ABSTRACT:
A glass cutter's table for controllably breaking glass sheets along straight lines includes a supported rigid panel having intersecting first and second arrays of downwardly recessed parallel elongated straight grooves. Pneumatically expandable tubing having a braided sleeve is disposed within the grooves and connected to a valve-controlled source of pressurized gas. When inflated, the tubing protrudes above the top surface of the panel. The tubing is of sufficiently thin walled construction that the weight of an overlying sheet of glass compacts the deflated tubing to a thickness of about twice the wall thickness of the tubing.
