A MULTIPLY TISSUE PAPER AND A METHOD OF MAKING IT |
摘要 |
A method of making a multi ply tissue paper web. The tissue web (10) is wound a plurality of revolutions in a helical manner to form a tube-like shape (12) or alternatively the shape of a flattened tube, in which the edges (11) of the tissue web of adjacent revolutions are partly overlapping, located substantially edge to edge or are located a small distance apart. The thus formed tube is then flattened to form a double- or multiply web (13). Alternatively tissue web is pulled out in the form of a helically twisted tube (15) from the centre of a centre-fed roll (14) of web material, and subsequently flattening the tube.
