Abstract
A grinding wheel for grinding the edges of glass sheets is mounted on a vertically adjustable drive shaft. The drive shaft is rotated by a motor and is raised and lowered by a pneumatic cylinder. Vertical movement of the drive shaft occurs relative to the motor. The pneumatic cylinder is coupled to the drive shaft by a rotary joint, and the vertical limits of movement of the shaft are defined by two vertically adjustable stops. Vertical movement of the drive shaft occurs relative to the motor. By raising and lowering the grinding wheel between the two stops, the apparatus can grind the edges of glass sheets having different thicknesses.
