Web printing apparatus with printing plate cylinder and web speed control

Image Number 4 for United States Patent #4541335.

An improved printing apparatus for printing a running web is proposed which includes printing units each having a plate cylinder adapted to carry two plates, a pair of impression cylinders mounted in diametrically opposite directions, and adjust rolls for guiding the web so that the length of web existing between two contact points will be three or more odd number of times as long as the printing length. The plate cylinder or the web is controlled so that during the printing, the peripheral speed of the plate cylinder will be equal to the web speed, and from the print end to the next print start, the plate cylinder will move for a distance equal to the gap between the two plates.
