Abstract
The invention relates to an apparatus (10, 80) and method (160) for cutting, printing or embossing a continuous sheet (26) of material. The apparatus (10, 80) comprising a tool element (12), at least two anvils 14, 16 which are co-operable with the tool element (12), and a phase adjustment device (24). The tool element (12) is configured to have a constant surface speed during operation of the apparatus (10, 80). The apparatus (10, 80) is adapted to receive the continuous sheet (26) at a constant speed into the apparatus (10, 80), and being adapted to output the continuous sheet (26) at a constant speed from the apparatus (10, 80). The phase adjustment device (24) is operable to adjust a speed of the continuous sheet (26) within the apparatus (10, 80) in order to adjust a phase of alternate parts of the continuous sheet (26) to be cut, printed or embossed by each anvil (14, 16) as it co-operates with the tool element (12).
