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.

Dependent claims

A method of cutting, printing or embossing a continuous sheet using an apparatus comprising a tool element having a surface, at least two anvils, which are co-operable with the surface of the tool element, and a phase adjustment device comprising at least two carriages, each carriage being associated with a respective anvil, each carriage having two rollers such that a respective portion of the continuous sheet is between the two rollers of each carriage, the continuous sheet having a constant speed into and out of the apparatus, the method comprising:

operating the tool element with a constant surface speed;
using the phase adjustment device to adjust a speed of the continuous sheet within the apparatus by moving each carriage to provide said adjustment of the speed of the continuous sheet in order to adjust a phase position of alternate parts of the continuous sheet;
passing each respective portion between the surface of the tool element and the anvil associated with each carriage and moving each carriage to adjust said speed of the continuous sheet by adjusting a speed of each respective portion;
and
cutting, printing or embossing the alternate parts of the continuous sheet using alternate anvils of the at least two anvils co-operating with the tool element.
