Multiply tissue paper and a method of making it

摘要

A method of making a multi ply tissue paper web. The tissue web material is wound a plurality of revolutions in a helical manner to form a tube-like shape or alternatively the shape of a flattened tube, in which the edges of the web material 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. Alternatively web material is pulled out in the form of a helically twisted tube from the centre of a centre-fed roll of web material, and subsequently flattening the tube.
