Definitions

  • a paper rolling device for paper making machines has two adjacent rolls, one of which serves normally as a bobbin for the paper.
  • the second roll which is a driven one has a perforated zone located close to one end of the zone.
  • a suction box is located inside the second roll and below the perforations which is followed by a blow box, thereby preventing a narrow strip of paper passing between the rolls from being wound upon the second roll.
  • the present invention concerns a paper-rolling device for use in paper machines, comprising two parallel cylinder rolls, one of which acts as bobbin for the paper roll to be wound and through the pressure nip defined by which rolls the paper to be wound on the roll acting as bobbin for the paper roll passes.
  • the object of the present invention is to facilitate the introduction of the paper strip between the said rolls, and in the invention this is accomplished by inhibiting the generation of the said pressure zone or at least appreciably reducing its strength at least in that part of the press nip defined by the rolls through which the said paper strip is passed.
  • the invention is mainly characterized in that the mantle surface of the second roll cooperating with the rollwhich takes care of the winding-on, or of the'so-called Pope cylinder roll, has been provided with a zone extending over the circumference of the roll and provided with holes piercing through the mantle and which zone has a width substantially smaller than the length of the roll.
  • the actual width of the zone depends on the length of the roll and is a fraction of that length.
  • FIG. 1 is a section on line 1-1 of FIGQZ.
  • FIG. 2 is a perspective view of the device shown in FIG. 1, with some parts broken off.
  • the rolling device comprises two cylinder rolls 1 and 2, of which at least one roll, or the so-called Pope cylinder roll is a driven roll.
  • the roll I normally acts as bobbin for the paper to be wound on.
  • the paper strip 4 which is a narrow part of the web is presented to one end of thepress nip defined by the rolls 1 and 2 and this strip is passed through between the rolls 1 and 2, whereupon one begins to increase the width of the paper strip at the other end of the machine until it conforms to the full working width of the machine and the paper web is guided to encircle the roll 1.
  • a perforated zone 5 has been provided, which prevents the formation of a pressure zone or essentially reduces its strength in front of the press nip defined by the rolls 1 and 2.
  • the actual width of the perforated zone depends upon the length of the roll 2 and is a fraction of that length.
  • the design of one end of the roll 2 has been changed from normal by fixing the combined end piece and journaling piece 3 at greater than usual depth inside the roll 2.
  • the efficiency of the perforated zone 5 may be improved by arranging on its inside, below the press nip defined by the rolls 1 and 2, a suction device, e.g. a suction box 6 belonging to prior art in itself, which produces a suction zone 8 on the upper surface of the roll 2.
  • a suction device e.g. a suction box 6 belonging to prior art in itself
  • a blow box 7 or equivalent which creates a pressure zone 9 and prevents the paper strip from winding itself around the roll 2.
  • a paper rolling device for paper making machines comprising two interengaging rolls, a length of paper being adapted to pass between said rolls and to be wound upon one of said rolls, the other roll having a perforated zone extending over a fraction of its length, a suction device located within said other roll and communicating with some of perforations of said zone and a blowing device located within said other roll and following said suction device, said blowing device communicating with other perforations of said zone.
