Abstract
A die-cutting device for die-cutting labels includes a die-cutting cylinder and a counterpressure cylinder. A distance between the die-cutting cylinder and the counterpressure cylinder is adjustable. Accordingly, the die-cutting cylinder is locked in position by a locking force and the counterpressure cylinder is displaceably supported by a guide. The locking force and the guide generally form a right angle. A narrow-web printing press includes such a die-cutting device.
Claims12
A die-cutting device, comprising:
- a die-cutting cylinder rotatable about an axis of rotation;
- a guide;
- and
- a counterpressure cylinder rotatable about an axis of rotation being generally parallel to said axis of rotation of said die-cutting cylinder, a distance between said die-cutting cylinder and said counterpressure cylinder being adjustable, by a locking force locking said die-cutting cylinder in position and said counterpressure cylinder being displaceably supported in said guide for adjusting the distance, the locking force and said guide generally forming a right angle with each other.
