Definitions

  • This invention relates to improvements in paper-making and particularly in the woven fabric from which is formed the endless belt onto which is applied a fibre/water slurry at the "wet end" of a paper-making machine.
  • Wire marking is the impression which the knuckles of the wire (or fabric) make in the sheet of paper and linting is the condition where fibres on the wire side of the sheet are loose and come off during the printing process, causing problems in printing quality.
  • the topside of the wire consists of cross direction weft floats, which provide support to the sheet and are positioned such that the longest distance to be . bridged by the fibres is the length of one hole.
  • the topside In a standard 4 shed or 5 shed fabric the topside consists of machine direction warp floats which present a surface to the sheet which has long machine direction valleys, into which the fibres can fall. The longest distance to be bridged in this case is the length of three holes plus the diameter of two wefts.
  • An object of this invention is to obviate or mitigate these problems.
  • a paper-making machine fabric woven in a five-shed pattern repeated over five wefts, one face of the fabric comprising single weft knuckles and single and double warp knuckles and the other face of the fabric comprising single warp knuckles and single and double weft knuckles.
  • the fabric may be made of a synthetic material, e.g. a polyester.
  • a synthetic material e.g. a polyester.
  • the face of the fabric on which .it is intended to apply the fibre/water slurry comprises single weft knuckles and single and double warp knuckles in a broken twill pattern.
  • the weft and Warp knuckles are substantially monoplanar which gives a very acceptable mark to the paper produced.
  • the longest valleys between adjacent warps is the length of two holes plus the diameter of one weft. This has the advantage of minimal disturbance of the fibres which have fallen into the valley, when the formed paper is removed from the fabric.
  • the opposite face of the fabric comprises single warp knuckles and prominent single and double weft knuckles which will take the wear in use.
