在胶片涂布机中广泛采用辊筒系统传送片基和胶片。系统中主要由被动托辊和主动辊组成。无论是那一种型式辊筒,都是凭借摩擦力传递运动。如何合理设计辊筒传送系统,确保系统中主动辊能拖动胶片及胶片带动被动托辊,从而使胶片和辊筒间相对滑动
Roll systems and films are widely used in film coaters. The system mainly consists of passive roller and driving roller. No matter which type of roller, are based on friction transmission movement. How to design the roller conveyor system reasonably and ensure that the driving roller in the system can drag the film and the film to drive the passive roller so as to make the relative sliding between the film and the roller
