Patent number: 6596127Abstract: Method of producing a paper having a three-dimensional pattern of alternating raised and recessed portions which has been provided in connection with impulse drying, at which the wet paper web (10) is passed through at least one press nip (12) comprising a rotatable roll (13) which is heated and that the paper web during the passage through the press nip is given a three-dimensional pattern of alternating raised and recessed portions either by means of a pattern wire, band or belt and/or by a pattern on the heated roll (13) and where the paper web (10) after said press nip (12) is led around an essential part of the periphery of the heated roll (13) in order to provide an additional drying of the paper web while this is still in contact with said three-dimensional pattern.Type: GrantFiled: April 2, 2001Date of Patent: July 22, 2003Assignee: SCA Hygiene Products ABInventors: Holger Hollmark, Lennart Reiner, Thomas Billgren, Kaveh Tondkar, Mats Söderberg, Bengt Järrehult

Patent number: 6444089Abstract: Method of producing a paper having a three-dimensional pattern of alternating raised and recessed portions which is given the paper in connection with impulse drying. The paper web has a varying material composition as seen in its thickness direction, so that it at least in an outer layer contains an amount of a material that softens, melts or hardens in the temperature interval 100-400° C. or in some other way contributes in stabilizing the pattern structure that has been given the paper. It is further referred to an impulse dried paper produced according to the method.Type: GrantFiled: April 2, 2001Date of Patent: September 3, 2002Assignee: SCA Hygiene Products ABInventors: Holger Hollmark, Lennart Reiner, Thomas Billgren, Kaveh Tondkar, Mats Söderberg, Bengt Järrehult

Publication number: 20020092633Abstract: Method of producing a paper having a three dimensional pattern which has been given the paper web in connection with drying the paper web, at which the wet paper web (10) is passed through at least one press nip (12) comprising a rotatable roll (13) which is heated and that the paper web during the passage through the press nip is given said three dimensional pattern either by means of a pattern provided on the heated roll (13), alternatively on a member surrounding the roll or by means of a patterned wire, band or belt and where said pattern is pressed into the paper web against a counter means (11,14). After said press nip (12) the paper web (10) is taken off from the heated roll (13) by means of a detaching roll (16) and is creped against said detaching roll.Type: ApplicationFiled: December 19, 2001Publication date: July 18, 2002Inventors: Janerik Odhe, Bengt Jarrehult, Holger Hollmark, Lennart Reiner, Thomas Billgren, Ingvar Klerelid

The wet paper web before said press nip is exerted to a creping- or other compacting procedure which foreshortens the length of the paper web. The invention also refers to a paper produced by the method, said paper having a high extensibility.Type: GrantFiled: April 2, 2001Date of Patent: July 9, 2002Assignee: SCA Hygiene Products ABInventors: Holger Hollmark, Lennart Reiner, Hans Wallenius, Thomas Billgren, Ingvar Klerelid

Patent number: 5840152Abstract: An apparatus for joining a first web (8) consisting of plastic material to a second web (9) consisting of absorbent material, wherein the arrangement includes a cooling-roll (1), a counter-roll (2), and means for feeding the first and the second webs through the nip defined between the cooling-roll and the counter-roll, the webs being pressed together in the nip, and wherein the plastic material in the first web (8) is in a plastic state when entering the nip. A pattern of molds (5) having air-permeable bottoms is arranged over at least a part of the mantle surface of the cooling-roll (1) and a vacuum box (7) is arranged inwardly of the cooling-roll mantle in the region of abutment of the first web (8) with the cooling roll, with cooling devices (3, 4) for cooling the cooling-roll mantle from outside the roll.Type: GrantFiled: June 11, 1997Date of Patent: November 24, 1998Assignee: Molnlycke ABInventors: Thomas Billgren, Maurice Leclercq, Francis Robert
