ABSTRACT:
The paper web capturing apparatus includes two capturing rollers, preferably disposed downstream of the last printing station, which when used in a prime-and-verso printing machine both have the same diameter as the printing station cylinders. Both cylinders acting as capturing rollers are provided with a rubber blanket and are driven at approximately the linear speed of the web. They are in continuous engagement with the web of material to be printed. During normal operation, the cylinders of the capturing apparatus effect an enhancement of the printing, in particular of the color printed at the last printing station, and in the event of web tearing the web is wrapped about one of the cylinders, which are positioned resiliently against one another.
