安定な駆動源であるためウエブのテンシヨン変動
が発生しやすいという欠点があつた。 However, the driving force of the impression cylinder due to the frictional force between the impression cylinder and the web when there is no contact between the impression cylinder and the plate cylinder is insufficient compared to the mass of the impression cylinder, and the web itself is highly elastic, making it an unstable driving source. Therefore, there was a drawback that tension fluctuations in the web were likely to occur.
