  • Roller scriber apparatus for scribing glass
    Patent number: 4183274
    Abstract: Improved apparatus for scribing glass wherein the dimensional interference for entry is controlled, the force applied is nearly constant over a range of glass thicknesses and the scribing wheel is restrained within close tolerances to prevent wheel wobble and/or wander. The invention provides a very high quality fracture of the glass and allows separation to be delayed for at least as much as eleven months after scribing. Scribing may be accomplished in either of two pass directions.
