Abstract
The invention relates to an apparatus and method for cutting, printing or embossing a continuous sheet of material. The apparatus comprises a tool element, at least two anvils, which are co-operable with the tool element, and a phase adjustment device. The tool element is configured to have a constant surface speed during operation of the apparatus. The apparatus is adapted to receive the continuous sheet at a constant speed into the apparatus, and being adapted to output the continuous sheet at a constant speed from the apparatus. The phase adjustment device is operable to adjust a speed of the continuous sheet within the apparatus in order to adjust a phase of alternate parts of the continuous sheet to be cut, printed or embossed by each anvil as it co-operates with the tool element.
