  • Patent number: 11220785
    Abstract: A tissue machine (1) has a Yankee (3) and a shoe roll (4) that forms a nip with the Yankee (3). The nip has a maximum extension from an entry point (7) to an exit point (8). A flexible belt (9) forms an outer circumference of the roll (4). A fabric (10) carries a fibrous web (W) to the nip and passes through the nip with the web. The fabric (10) reaches the circumference of the roll (4) at a first contact point (11) and wraps the roll (4) from the first contact point to the nip. A mechanical support (12) inside the belt (9) supports the belt (9) between the first contact point (11) and the nip. The fabric (10) wraps the roll (4) from the first contact point (11) by more than 80°. The invention also relates to a method of operating the machine.

  • Publication number: 20150060000
    Abstract: The invention relates to an extended nip roll (5) capable of forming a press nip (N) with a counter roll (7) which press nip (N) has an extension in a machine direction when the extended nip roll (5) cooperates with the counter roll (7). The extended nip roll (5) comprises a flexible jacket; an elastic press body (13) arranged inside the flexible jacket. The top side (14) of the press body (13) is beveled in such a way that, in the machine direction, a working surface (15) of the top side has a downstream end (16) which, in the machine direction, is followed by an exit side surface (17) that diverges from the interior surface (11) of the flexible jacket (10).The press body (13) further has at least a first and a second internal pressure chamber (18, 19). The pressure chambers (18, 19) can be pressurized such that the press body (13) expands.

  • Publication number: 20080098227
    Abstract: The present invention relates to a method of enabling secure transfer of a package of information in a digital communications network from a sender to a receiver. According to the method a package of information is encrypted and provided to the receiver. A third party is provided with an encryption key having such a format that it is unable to decrypt said package of information. The encryption key is, upon positive identification of the receiver, providable from said third party to the receiver, and enables, with the involvement of a supplementary encryption key of the receiver, decryption of the package of information.

  • Patent number: 6047917
    Abstract: A reel-up in which paper is reeled up on reeling drums to form paper reels is provided. The reel-up comprises two stand members provided with stand rails to support the reeling drum. A secondary system consisting of first and second secondary units for receipt of new reeling drums is provided adjacent to the stand members. Each secondary unit comprises a first and a second secondary member, each arranged adjacent one of the stand members. Both secondary members of each secondary unit are arranged at the outer sides of the stand members so that the deleterious effects of paper dust, etc. between the stand members are eliminated.

  • Patent number: 5816528
    Abstract: A reel-up in which paper is reeled up on reeling drums to form paper reels, said reel-up having two parallel stand members; a surface winding mechanism in the form of a rotating surface winding drum and/or a belt to carry the web and deliver it to one of said reeling drums or a paper reel formed or being formed thereon; and a secondary system including first and second secondary units for alternate receipt of new reeling drums. Each secondary unit, includes an outer first secondary member and an inner second secondary member, each of the secondary members having a linearly movable secondary body, an actuator for moving the secondary body, and a press device to maintain a predetermined linear pressure in the nip between the surface winding means and the paper reel as it increases in size.
