Abstract
A glass breaking system is provided for breaking large sheets of glass into small sheets, in which a laser beam having an elongated beam spot shape, with a largest dimension which is at least 20 mm, more preferably at least 30 mm, and most preferably at least 40 mm, is moved across a glass sheet to produce a partial crack score line. The glass sheet is then separated along the score line by applying a bending moment in the area of the partial crack.
