  • Patent number: 7947203
    Abstract: The invention relates to a procedure and an apparatus in dry formation of a fibre layer, in which procedure fibre-containing air is passed through a forming wire (7) moving via a former (2) or an equivalent distributor unit and further through a suction box (8) or equivalent placed below the forming wire, and which air is circulated back to the upper part of the same or another former. In the solution of the invention, the air circulated through the suction box (8) is passed to the upper part of the former via channels (17) with an adjustable flow rate.

    Abstract: A macroscopically monoplanar secondary belt for manufacturing a cellulosic fibrous structure is provided. The belt, having two mutually orthogonal principal directions, a machine direction and a cross machine direction, and having a reinforcing structure; and a framework of protuberances joined to said reinforcing structure and extending outwardly therefrom to define deflection conduits between the protuberances, the framework of protuberances having a semicontinuous pattern and the deflection conduits having a semicontinuous pattern, is further provided. The protuberances and the deflection conduits have a vector component extending substantially throughout one principal direction of the belt, each protuberance of the pattern being spaced apart from an adjacent protuberance in the pattern. The protuberances have primary protuberances having a first width, T and the nodes have a second width, N, wherein a ratio of N to T is from about 1.5 to about 5.

  • Publication number: 20110114278
    Abstract: A woven filtration fabric for cellulosic sheet formation. The warp yarns comprise intrinsic binder yarn pairs, and a set of dedicated machine side layer warp yarns. The members of each intrinsic binder yarn pair alternate with each other to define a single combined path in each layer. Whenever a member interweaves with a machine side layer weft yarn, at least one machine side layer warp yarn interweaves with the same weft yarn in the same knuckle. In some embodiments, the members form double knuckles in the machine side layer, firstly together with a first machine side layer warp yarn and then together with a second machine side layer warp yarn. The warp yarn path ratio of machine side layer warp yarns to single combined paths of the intrinsic binder yarn pairs is at least 1.5:1. The fabrics provide increased center plane resistance, resulting in improved drainage and sheet uniformity.

  • Publication number: 20110108224
    Abstract: The object of the invention is to provide a papermaking felt which can be easily engaged in a papermaking machine, wherein the work time for engaging the felt is short, the initial warming-up period until reaching the highest papermaking speed is short, and the felt life is long. This object is achieved by integrating and attaching by dispersion in the batt layer of the felt a polymeric elastomer having high deformability when pressure is applied and good recoverability after pressure is applied. When said polymeric elastomer is in the form of a film and when measured at a room temperature of 20° C. and a relative humidity of 65%, the 100% modulus value of the film is 1 to 100 kg/cm2, the residual strain after 100% elongation is 30% or less, and the attached amount of polymeric elastomers is 0.5 to 20 wt. % of the papermaking press felt weight. Examples of materials include polyurethane elastomers, polyethylene elastomers, styrene-butadiene rubber, silicone rubber, or the like.

  • Patent number: 7935225
    Abstract: Papermaker's forming fabrics including extruded thermoplastic monofilaments formed from a polymer blend consisting of from about 51%-90% pbw (parts by weight) of a poly(ethylene naphthalate) (PEN) polymer having a melt point of from 249° C. to about 278° C., most preferably between about 262° C. and 273° C., and an intrinsic viscosity of from 0.45 to about 0.95, preferably from about 0.65 to about 0.85, along with from about 49%-10% pbw of a poly(ethylene terephthalate) (PET) polymer having an intrinsic viscosity of between about 0.55 to about 1.05, preferably from about 0.85 to 1.0. Monofilaments formed from the novel polymer blend exhibit physical properties differing from those obtained from monofilaments formed of 100% PEN polymer, making them particularly suitable for use in weaving and processing the forming fabrics of the present invention.
