Abstract
The invention is to a device and method, for cutting a can blank in which case an end section of the can blank is severed. The can blank is moved by means of a conveyor arrangement at a constant speed about a first axis of rotation. Preferably, a laser beam is used as the cutting means. A deflecting arrangement deflects the laser beam to a focal point where the side surface of the can blank is located. Due the rotation of the can blank about its longitudinal axis, the axial end section of said can blank is severed. The focal point of the laser beam does not change relative to the longitudinal axis of the can blank during the laser cutting operation.
