Patent ID: 7029546

Claim:
A method for manufacture of a paper sheet comprising at least two plies of creped cellulose wadding, involving unwinding a first ply in a form of a strip from an unwinder, embossing it on an embossing group in order to form protuberances on its surface, unwinding a second ply in the form of a strip from an unwinder, guiding it downstream of the embossing group as an unembossed second ply, superposing the two strips, with protuberances toward an inside between the two strips, and applying a connecting means so as to make the two plies integral with one another, wherein immediately upstream of said connecting means, a tension-regulating means is applied to one of the two strips in the running direction, so that the two strips have a same elastic deformation in a running direction when the connecting means is applied; and wherein the tension-regulating means is applied to the unembossed second ply and accelerates said second ply in the running direction, so that the two strips have the same elastic deformation in the running direction when the connecting means is applied.
