  • Patent number: 5965208
    Abstract: A coater belt for carrying and supporting a web through a coating station on a paper or board machine, or an off-line coater, said belt comprising an endless base member and at least a first surface layer. Said surface layer is an impermeable coating comprising a first material and a particulate filler material. The filler material which are present in the web-contact surface provide a well-defined roughness on micro-scale of said web-contact surface. The web-contact surface further presents a well-defined surface energy for accomplishing an adhesion to the web for picking-up the web at an entrance side of the coating station and for holding the web against the coater belt during its path through the coating station.

  • Patent number: 5915422
    Abstract: An improvement (20) for producing an enhanced seam on a machine clothing for a paper or cellulose machine, especially, but not exclusively, when using flat filament yarns (26) in the machine direction of the clothing is shown. The seam has two preformed yarn spirals (20), which are each bound, by the machine direction yarns (26) of the clothing, to one seam edge, thereby each forming a row of seam loops (22) which are meshable with each other and joinable onto each other by means of a pintle wire. At least one spiral (20), preferably both, is, between neighboring seam loops (22) in the row of loops, preformed with special securing portions (24), to which the spiral (20) is attached at the corresponding seam edge. The securing portions (24) hold the seam loops (22) spaced apart and are extended substantially in the longitudinal direction of the spiral (20).

  • Patent number: 5829488
    Abstract: A dryer fabric for use in a dryer section having a closed transfer in a papermaking machine. The dryer fabric has a structure of woven threads with one side, called the paper side, being adapted to support and abut against a paper web in the dryer section. At least some of the threads contacting against the paper web are hydrophilic, thereby providing for adhesion between the dryer fabric and the paper web.
