Document Type and Number:
Japanese Patent JP2958766
Kind Code:
B1
Abstract:
An offset perfecting press is disclosed wherein a web is printed on both sides while traveling between a pair of blanket cylinders. In the event of a web break downstream of the blanket cylinders, the web is conventionally cut off immediately upstream of the blanket cylinders. Thereupon, on the downstream side, the web will stick to either of the printing cylinders due to the adhesiveness of the ink thereon, tending to be wound about the cylinder all the way down to the point of break. In order to prevent this a pair of opposed web cut blades are disposed. Intermediate the printing cylinders and a downstream guide roller. Upon web break a pressure roller is actuated into rolling engagement with the guide roller via the web, urging the web forwardly by inertial rotation of the guide roller. Thus tensioned between either of the printing cylinders and the guide roller, the web is held tightly against either of the opposed blades thereby to be cut off.
