A rotating belt ( 10 ) is used to finish the edges ( 23 ) of glass sheets ( 11 ), such as, the thin sheets (e.g., 0.7 mm) used as substrates for liquid crystal displays (LCDs). The edge ( 23 ) of the sheet ( 11 ) engages the working zone ( 15 ) of the belt ( 10 ) along a line segment ( 17 ) whose included angle with the direction of motion ( 19 ) of the belt ( 10 ) is less than 10°. The working zone ( 15 ) is brought into contact with the edge ( 23 ) by a pressure sensitive platen ( 13 ) which can accommodate errors in the positioning of the sheet ( 11 ) at the finishing station ( 12 ).
