Abstract (en)

[origin: EP2295634A2] A method for forming a continuous paper web extensible in the longitudinal direction and in the transverse direction, characterised by passing a paper web (2), having a water content of between 20% and 80%, into contact with at least one deviation roller (4), the axis of which forms an angle between 30° and 60° to the longitudinal axis of the web, and subjecting the web, at the contact surface between said paper web and said roller, to a compaction which is prevalent in one of the two directions parallel to and perpendicular to the roller axis.
