    摘要: CONVEYOR ROLLS FOR SUPPORTING AND CONVEYING GLASS SHEETS IN A PRESS BENDING APPARATUS. EACH ROLL COMPRISES A DRIVEN SHAFT AND A SHEET SUPPORTING SLEEVE SURROUNDING SAID SHAFT AND ADAPTED FOR ROTATION WITH OR RELATIVE TO SAID SHAFT. THE SHAFT HAS LIMITED FRICTION DRIVING ENGAGEMENT WITH THE SLEEVE WHICH PERMITS THE ROLL TO ADVANCE AN UNRESTRAINED SHEET SUPPORTED THEREON BUT ALLOW SLIPPAGE TO OCCUR BETWEEN THE SLEEVE AND THE SHAFT WHEN MOVEMENT OF THE SHEET IS RESTRAINED.
