Embodiment Construction

[0045] In the following description, the same or similar elements will be denoted by the same reference numerals throughout the various drawings.

[0046] figure 1 A stack 1 of interfolded webs, ie a (first) web section 2 and a second web section 3 , is shown. The first and second web sections 2, 3 are divided into separable hygiene sheet products (e.g., paper hygiene products, paper hygiene products, etc.) by perforation lines 4 extending laterally across the elongated hand towel products, tissue paper products, etc.). For clarity, the perforated line 4 is in figure 1 is shown as a solid circle in . Although the term "line of perforation" is used, the definition given above applies as it is assumed that the term is used to define intermittent or continuous weakening, where the remaining strength of the web is in the range between 4% and 50% and Preferably between 4% and 15%.

[0047] The perforation line 4 for the first web section 2 is positioned offset from the perfora...

Abstract

A method for producing stacks (1) of individual web sections (2; 3), such as tissue web sections from a continuous web of material (2a; 2b), comprises the steps: (a) directing the continuous web (2a; 2b) to a perforating station (27); (b) perforating the continuous web (2a; 2b) at predetermined intervals and forming sheets (5) of web material between consecutive perforation lines (4) extending laterally across the continuous web (2a; 2b), the perforating being carried out by means of at least one perforation element (26) arranged at the circumference of a perforation roller (24); (c) directing the continuous web (2a; 2b) to a cutting station (31; (d) cutting at second predetermined intervals the continuous web (2a; 2b) into web sections (2; 3) by means of a cutting element (38) acting against an anvil element (37), in order to generate a clear cut or a tab-bond; (e) folding the web sections (2; 3) by means of a folding roll (32); and (f) stacking the folded web section (2; 3) to generate a stack (1) of folded sheets.

Description

technical field [0001] The present invention relates to a method for manufacturing a continuous web of material into a stack of individual web sections, eg tissue paper web sections. Furthermore, the present invention also relates to a device for manufacturing a continuous web of material into a stack of sheets, eg tissue paper sheets, and a stack of folded hygiene products, eg paper or woven products. Background technique [0002] Hand towels, napkins and similar articles for personal and household use are used for many different purposes in washing stations, toilets, offices and public places and for cleaning and machine wiping tasks. Different articles may comprise a variety of different qualities and constitute different hygiene or wiping materials, such as paper and tissue. Synthetic materials, natural materials and nonwoven blends thereof can also be used. The articles can have different uses and can be used inter alia for hygiene, wiping, absorbing, cleaning and pol...
