Abstract
An improved printing apparatus has printing units, a pair of feed rolls, a pair of pull rolls, a speed adjusting unit having a pair of rolls, and a control unit. The speed adjusting unit reciprocates linearly to advance and retreat the web in the printing units. While the web is being printed, the feed and pull rolls are stopped. While it is not being printed, they are driven to feed the web for a distance equal to one printing length. The speed adjusting unit is driven so as to move at a speed equal to half the peripheral speed of the plate cylinder while the web is being printed.
