Patent ID: 8146386

Claim:
A method for producing a glass sheet, said method comprising the steps of: melting batch materials to form molten glass and processing the molten glass to form the glass sheet; drawing the glass sheet using a fusion draw machine; routing the glass sheet along a nosing device; and scoring the glass sheet using a scoring device comprising a score wheel, a first linear motor/actuator configured to move said score wheel in an X-direction along a side of the glass sheet, a second linear motor/actuator configured to move said score wheel in a Y-direction towards the side of the glass sheet, a first actuator and a ranging sensor, the scoring comprising: obtaining positional information from the ranging sensor about a location of the side of the glass sheet; operating said second linear motor/actuator to move said first actuator and said score wheel in the Y-direction using said positional information from said ranging sensor; operating said first actuator to move said score wheel relative to said second linear motor/actuator further in the Y-direction; and wherein said score wheel applies a constant force to the side of the glass sheet during the scoring.
