Abstract

A method for producing stacks of individual web sections involves: (a) directing the continuous web to a perforating station; (b) perforating the continuous web at predetermined intervals and forming sheets of web material between consecutive perforation lines extending laterally across the continuous web, the perforating being carried out via at least one perforation element arranged at the circumference of a perforation roller; (c) directing the continuous web to a cutting station; (d) cutting at second predetermined intervals the continuous web into web sections via a cutting element acting against an anvil element, to generate a clear cut or a tab-bond; (e) folding the web sections via a folding roll; and (f) stacking the folded web section to generate a stack of folded sheets.
