  • the present invention relates to a method of operating a slitter winder according to the preamble of patent claim 1.
  • the invention also relates to an application apparatus according to the preamble of patent claim 7.
  • a machine roll being produced in a paper machine is often slit in the longitudinal direction into partial webs, which form customer rolls or market rolls of desired width. Attaching the cutting point of the market rolls produced in the slitter winder, i.e. the "tail" of the web, automatically after the rewinding is one of the increasingly important features in the paper finishing process. This is first of all due to the. fact that less personnel is working today at the slitter winder at a time than before and roll changes, web feeding and other compulsory measures take so much of their working time that there is not much time for attaching the roll tails manually by means of a tape of corresponding means. Further, rolls the tails of which have not been secured cause problems on conveyors; a further problem is that the roll has time to become slack before it is packed.
  • adhesive refers in addition to a mere adhesive also to a tape or any other arrangement producing the corresponding effect.
  • adhesive stripe must be understood to cover also glue or tape, and the application may have a form deviating from a straight line and be for example a spiral.
  • the web is slit in the longitudinal direction to at least two partial webs, which are wound to separate rolls and, when the rolls have reached the desired diameter, the web is cut and the cut end of the web is bound to the surface of the complete roll by means of an adhesive so that adhesive is brought by means of an adhesive applying apparatus to the surface of the web to the side which remains between the web and the roll when the adhesive arrives to the roll.
  • Adhesive is brought to the surface of the web while the web is moving and an adhesive stripe essentially in the transverse direction of the web moving direction is formed to the surface of the web.
  • the method is mainly characterized in that introduction of adhesive to the surface of the web is carried out during the decelerating movement of the web.
  • introduction of adhesive to the surface of the web is carried out during the decelerating movement of the web.
  • the adhesive stripe is formed or a tape attached with an application apparatus, where the speed component of the application head in the direction of the web movement is kept essentially as great as the speed of the web at each moment. In this way, an adhesive stripe essentially in the direction transverse to the running direction of the web can be provided on the surface of the web irrespective of the movement of the web.
  • Application of adhesive performed during the decelerating movement is according to a preferred embodiment achieved by changing the movement direction of the application head during the adhesive application process. [0014] Application of adhesive performed during the decelerating movement is according to another preferred embodiment achieved by changing the movement speed of the application head during the adhesive application process.
  • An adhesive stripe can be produced also by an application apparatus comprising several separate application heads, which together form an adhesive stripe to each partial web.
  • the apparatus according to the invention for applying adhesive to a moving web comprises an application head disposed in connection with a support structure extending across the web essentially in the transverse direction.
  • the support structure comprises a guide extending across the web, onto which the application head has been movably installed and the application head has been arranged to create onto the surface of the web an adhesive stripe essentially in the transverse direction of the web movement direction while the web is moving.
  • the operation of the application apparatus may be improved further according to an embodiment of the invention by including in the apparatus means for changing the moving direction of the application head whereby the movement direction of the application head can be changed during the application of adhesive.
  • This arrangement allows forming an essentially transverse adhesive stripe during the decelerating movement of the web. This is preferably effected by supporting the application head over an articulated lever onto a carriage provided on the guide.
  • the operation of the application apparatus may be improved further according to an embodiment of the invention by including in the application apparatus means for changing the moving speed of the application head during the application of adhesive.

  • the operating model typically follows the form illustrated by a broken line.
  • the normal operating speed 10.1 is followed by a speed deceleration stage 10.2 and consequently, the running speed of the web is reduced to zero and the slitter winder is stopped for a certain time 10.3.
  • adhesive or a tape is brought to the surface of the web which later will attach the "tail" of the roll, i.e. the end of the web, to the roll.

  • the web is also cut at this stage after the adhesive point.
  • the adhesive or the tape is preferably disposed onto such a surface of the web that it stays at once against the surface of the completed roll. Otherwise the adhesive or the tape would stick to the reeling cylinder or a corresponding means formed by the first rewinding nip.
  • the slitter winder may be stopped, the completed rolls removed from the machine and the process started from the beginning in the normal way.
  • the running model follows the form indicated by the solid line. Then the normal operating speed 10.1 can be kept up longer and the decelerating stage 10.3 started later.
  • adhesive is brought to the surface of the web while the web is moving, during the deceleration stage.
  • the deceleration of the slitter winder is preferably followed by its stop. Subsequently the completed rolls are removed from the machine.
  • the capacity increase obtained when carrying out the method of the invention according to the model illustrated in figure 1 has been illustrated as the area covered with inclined lines.
  • the deceleration in the deceleration stage in other words the negative acceleration, need not be constant, thus with a certain application the form illustrated in figure 1 may be different.

Abstract

La présente invention concerne un procédé d'utilisation d'une coupeuse-bobineuse (20) selon lequel la bande (w) est fendue dans le sens longitudinal en au moins deux bandes partielles (wl) qui sont rembobinées en rouleau séparé (26). Selon le procédé, lorsque les rouleaux ont atteint un diamètre souhaité, la bande est coupée et l'extrémité coupée de la bande est fixée à la surface du rouleau terminé par de la colle appliquée par un appareil d'encollage (29) à la surface de la bande sur le côté qui reste entre la bande et le rouleau lorsque la colle arrive au rouleau. Le procédé est caractérisé en ce que la colle est appliquée à la surface de la bande pendant que la bande se déplace et qu'une bande adhésive (28, 28') sensiblement transversale par rapport au sens de la marche de la bande est formée par la colle sur la surface de la bande.
