Publication number: 20040163783Abstract: A method for producing a multi-ply web of flexible material, such as paper and nonwoven material. At least one first ply is separately embossed by a first embossing means to form a plurality of crests and depressions and is combined with at least one second ply. After combining the first and second plies, they are brought into a nip between a spiked roll and a smooth rigid roll, the spiked roll having a plurality of protuberances which are adapted to press together the first and second plies in points or spots to cause a mechanical ply bonding between the at least two plies. The first embossing means and the spiked roll are in register with each other so that the protuberances of the spiked roll will hit at least some of the depressions of the ply facing the spiked roll. The invention also refers to a multi-ply web produced by the method.Type: ApplicationFiled: March 1, 2004Publication date: August 26, 2004Applicant: SCA Hygiene Products GmbHInventor: Heinz Jurgen Muller

Publication number: 20040166290Abstract: In a process for laminating plies of tissue paper, at least two plies of tissue paper are combined and are embossed together in at least one embossing nip so that they are provided with substantially identical embossing patterns which consist of embossing protrusions. The embossed plies are then separated, and the separated plies are then displaced relatively to each other and are recombined. In the resultant recombined tissue, the maximum distance D in the displacement direction between an embossing protrusion of a first ply and an embossing protrusion of a second ply, which has been displaced relatively to said first ply, is set as a function of the height H of the embossing protrusions and the length L of the embossing protrusions in the displacement direction of the two plies, so that D is equal to the smaller one of the values of 12H and 14L.Type: ApplicationFiled: December 9, 2003Publication date: August 26, 2004Applicant: SCA HYGIENE PRODUCTS GMBHInventors: Dirk Sembritzki, Jan-Peter Brunback, Wolfram Schinkoreit
