  • Patent number: 10655276
    Abstract: A method produces or machines a roller which is suitable to be used in a machine for producing or processing a fibrous web. The roller contains a roller core and at least one functional layer. The method is characterized in that the method includes the application of a functional layer. The application of the functional layer is performed by applying a coating substrate to the surface of a roller core. The application takes place simultaneously over at least half the roller width, preferably over 75% of the roller width, particularly preferably over the entire roller width. The entire applied coating substrate or parts thereof are hardened, forming a solidified structure.

  • Publication number: 20170239912
    Abstract: A functional belt has a foam layer and at least one further functional layer. The foam layer and the further functional layer are joined to one another by laser transmission welding, in particular by NIR laser transmission welding. A method for producing a functional belt includes the following method steps: providing a compressible foam layer; providing a further functional layer bringing together the foam layer and the further functional layer and joining the compressible foam layer to the further functional layer by laser transmission welding, in particular by means of NIR laser transmission welding. A technical textile, in particular a fabric for use in a machine for the production or processing of a fibrous material web, preferably press felt of a paper machine, a sealing band or a textile-reinforced insulation material, includes, or is made of, such a functional belt.

  • Patent number: 9714483
    Abstract: An endless fabric belt for use in a paper, cardboard or tissue machine has machine-direction threads and cross-machine-direction threads. At least part of the threads are yarns composed substantially of a thermoplastic polymer material which is transparent for light of a wavelength. The fabric belt is a flat-weave with two front-side ends that are subsequently connected by bringing together end sections of the machine-direction threads in pairs with the formation of junction points and are woven with cross-machine-direction threads, forming a seam region. A material-to-material bond is formed in the seam region by absorbing light at the wavelength at yarn contact points. In the seam region, a plurality of spaced-apart, strip-shaped fabric sections are formed, in which the junction points and the yarn contact points which are connected to one another are arranged, and one strip-shaped fabric section without junction points is formed between two immediately adjacent fabric sections having the junction points.

  • Patent number: 9309624
    Abstract: A fabric for a papermaking machine is in the form of an endless belt which is closed in the circulating direction. The fabric has a first layer and a second layer which is arranged on the first layer. Each layer is formed by one or by a plurality of film-shaped tapes which adjoin one another and are arranged next to one another in the direction transversely with respect to the circulating direction. The side edges, which adjoin one another, of two film-shaped tapes of one of the two layers are arranged between the side edges of the two layers are arranged between the end edges of adjoining end edges of film-shaped tapes of one of the two layers. The film-shaped tapes of one of the two layers are connected over their full area to the film-shaped tapes of the other of the two layers.

  • Patent number: 8815057
    Abstract: A fabric for a papermaking machine is configured as a belt, the two side edges of which are configured in each case as closed lines. Furthermore, the belt is formed in one layer from a solid material and has pores which form passages between the two surfaces of the belt. The belt has regions with a width of approximately 400 micrometers (?m) or less. These regions extend in the longitudinal direction over the entire circumference of the belt, transversely with respect to the side edges, and include no pores formed therein.
