Definitions

  • the invention concerns a method in winding of a web, in particular of a paper or board web, in which method the web is wound onto a roll spool or equivalent through a nip between a roll or equivalent and the roll spool or equivalent.
  • the machine reel produced in a paper machine is often slit into component webs in a slitter- winder, out of which component webs customer rolls or commercial rolls of desired width are formed.
  • a slitter- winder In the commercial rolls formed in the slitter- winder, automatic fixing of the cutting point, i.e. the tail end of the web, to the full roll after winding and the fixing of the initial end of the web to the new roll spool are to-day ever more important properties in further processing of the paper.
  • Ply separation of paper means that, while the paper is fixed by gluing onto the spool from one side, rigid paper and, especially, board grades tend to straighten themselves to their linear form present on the machine reel and are split starting from the end of the web, in which case the starting of winding can fail completely or a fold is formed on the bottom of the roll. It can also be difficult to find a correct degree of weakening of the web when paper grades of different strengths are run.
  • the object of the present invention is to provide a method in which the drawbacks of the prior-art solutions are not present and by whose means the ends of the web can be fixed automatically to the roll and to the spool, respectively, simply and reliably.
  • the method in accordance with the invention is mainly characterized in that, in the method, when the roll that is formed on the spool becomes complete, a material strip with one adhesive face is fixed to the web at its edges transverse to the running direction of the web to fixing points so that the edges of the material strip are placed on the web at the fixing points at a distance between said fixing points in the running direction of the web that is shorter than the length of the material strip in the running direction of the web.
  • a material strip with one adhesive face is fixed to the face of the web, the length of said material strip in the running direction of the web being larger than the distance between its fastening points, and the web is cut off at a suitable point between the fastening points. After this, the material strip with one adhesive face is cut off so that one of its parts fixes the final end of the web to the complete roll and the other part fixes the initial end of the web to a new roll spool or equivalent.
  • the slitter- winder is stopped for the roll change, and the material strip with one adhesive face, preferably a one-sided tape, is fixed to the face of the web from two zones separate from one another. After this, the web is cut off between the tape fixing points. Since the length of the tape in the running direction of the web is longer than the distance between the fastening points, "unused" tape remains between the ends of the cut-off web. A part of this tape is used for fixing the tail of the roll to the roll, and the rest is used for fixing the web onto the roll spool, respectively.
  • the material strip with one adhesive face preferably a one-sided tape
  • the tape has been weakened in advance at the point at which it is supposed to be split between the fastening of the roll tail and the fastening of the web onto the spool.
  • the fixing by means of the method of the invention is reliable, because it is carried out across the cut-off area, whereby the risk of ply separation is eliminated fully.
  • Figure 1 is a schematic illustration of the stage of the method of the invention in which the slitter-winder has been stopped for the purpose of cutting off the web and fixing the tape.
  • Figure 2 is a schematic illustration of the stage of the method of the invention in which the web is cut off.
  • Figure 3 is a schematic illustration of the stage of the method of the invention in which the web has been cut off and the tape has been fixed between the final portion and the initial portion of the web.
  • Figure 4A is a schematic illustration of an exemplifying embodiment of cutting off the tape and fixing the tape to the face of a full roll.
  • Figure 4B is a schematic illustration of a second exemplifying embodiment of cutting off the tape and fixing the tape to the face of a full roll.
  • Figure 5 is a schematic illustration of the stage in the method of the invention in which one part of the tape has fixed the final portion of the web to the face of the complete roll and the other part of the tape has fixed the initial portion of the web onto a new roll spool.
  • the web W is wound over a roll 11 or equivalent onto the roll spool 13, around which the roll 12 is formed.
  • the winding takes place through the nip N between the roll 11 and the paper roll 12.
  • the web W has been stopped between the upper and lower holding members 24,25 of the web W cutting and tape fixing equipment 23.
  • the tape or equivalent material strip with one adhesive face, to be fixed to the web W is denoted with the reference numeral 22, and the web W cutting blade with the reference numeral 21.
  • the length Y (Fig. 3) of the tape 22 is larger than the length X of the web portion that remains between the tape 22 fixing points 26,27, because the tape 22 has been bent into a curved or equivalent form.
  • the web is moved in the direction S, in which case the tape 22 is tightened between its fixing points and becomes straight, the adhesive face being placed as the bottom face viewed in the direction of the figure.
  • the nip is opened, i.e. the roll 12 shifted to a distance apart from the nip contact with the roll 11, and when the tape is between the roll 11 and the roll 12, it is cut off by means of the blade 31, the first part 22 A of the tape 22 being guided onto the roll face, and by means of the press member 32 it 22A is pressed into contact with the roll 21 face, whereby the final end of the web has been fixed.
  • the tape 22 has been provided, for example, with a weakening, in which case, when the web W is tightened, the tape 22 is cut off at the weakening.
  • the operations to be carried out after this are similar to those illustrated in Fig. 4A.

Abstract

Procédé pour enrouler une bande, notamment une bande de papier ou de carton, selon lequel la bande (W) est enroulée sur un mandrin (13) ou similaire à travers une ligne de contact (N) entre un rouleau (11) ou similaire et le mandrin (13) ou similaire. Selon ce procédé, lorsque le rouleau (12) formé sur le mandrin (13) est achevé, une bande de matériau (22) comportant une face adhésive est fixée à la bande (W) au niveau de ses deux bords dans la direction de déplacement (S) de la bande vers des points de fixation (26, 27), la distance entre lesdits points de fixation étant sensiblement inférieure à la longueur de la bande (W) entre les points de fixation (26, 27).
