Definitions

  • This invention relates to a method for joining paper webs by means of tapes provided with a protective film, in accordance with which an adhesive surface of a first tape is exposed, said tape is attached substantially transversely to a first web at a distance from the end edge of the web so that it will extend from one longitudinal edge of the web to the other, the end portion of the web between the tape and the end edge of the web is removed, the same steps are repeated for a second web, and the junction point between the webs is covered with a second tape.
  • the invention also relates to a tape used in the method.
  • the joining is carried out with a two-sided tape.
  • a two-sided tape furnished with a protective film covering one side is fixed to the first paper web in the vicinity of the end edge thereof, whereafter the part of the web between the tape and the end edge of the web, the so called tail, is torn away by hand along the edge of the tape.
  • the protective film on the tape is removed and the other paper web is fixed on top of the tape and the end portion is torn away.
  • This known method has the disadvantage that the torn end edge of the paper web does not always exactly follow the edge of the adhesive surface of the tape, but the edge may have notches resulting from inaccurate tearing, on account of which some of the adhesive surface of the tape will appear. This will result in that the junction points on the paper web wound on a roll will adhere to the ply on top and the ply underneath. This can be prevented for the outer side of the junction by covering the junction with a one-sided tape, but a corresponding operation cannot be carried out on the lower side of the junction, since it rests against the previous ply on the roll.
  • the known method explained above has the disadvantage that the paper web will often adhere at the junction at least to the ply of the paper web underneath, wherefore the paper web may be broken when it is removed from the roll.
  • the junction point is also relatively thick, since there are superimposed therein two layers of paper and one or two layers of tape. The thickness of the web thus changes abruptly at this point, on account of which the printing roll may even be broken as a result of the impact thereupon.
  • the object of this invention is to provide a method for joining paper webs, wherewith a junction is produced which involves no danger of adhesion between the paper plies and which is still equally thin as, or thinner than, the junction produced by the known method.
  • the method of the invention is characterized in that both paper webs are fixed end to end onto the same side of the first tape and that the adhesive surface of the first tape is exposed in steps so that prior to the fixing of the tape to the first paper web a longitudinal adhesive zone having a width smaller than the width of the adhesive surface of the tape is exposed, and the remainder of the adhesive surface is exposed after the removal of the end portion of the first web prior to the fixing of the tape to the second web.
  • a butt joint covered on each side with one-sided tapes whose adhesive surface faces the paper is produced, and thus no outwardly exposed adhesive surfaces which could adhere to the other plies of the roll can be produced at the junction point. Furthermore, because of the butt joint between the paper webs the junction point is as thin as, or thinner than, the junction point produced with the previously known method, and the structure of the junction is gradually enlarging in thickness, wherefore the junction point will enter and leave the printing rolls softly.
  • the preferable procedure is that the adhesive zone located adjacent the longitudinal edge of the tape which is remote from the end edge of the first paper web is exposed first, and thereafter the adhesive zone adjacent the opposite longitudinal edge is exposed.
  • the invention also relates to a tape for joining paper webs, one side of said tape having an adhesive surface covered with a removable protective film.
  • the tape according to the invention is characterized in that the protective film comprises two longitudinal parts which can be separately removed from the adhesive surface.
  • the protective film for the -tape would be easily removable in two steps, according to one embodiment of the invention the protective film has a longitudinal slot or weakening line which separates the different parts of the film.
  • the parts of the film are substantially equally broad and that the combined width thereof corresponds to the width of the tape.
  • FIGS 1 to 6 illustrate the different steps of the method of the invention.
  • Figure 7 shows a cross-section of a produced junction.
  • Figure 8 shows a top view of a tape used in the method
  • Figure 9 shows a magnified cross-section of the middle portion of the tape.
  • the tape used in the method of the invention has been shown more closely in Figures 8 and 9.
  • the adhesive surface 2 of the one-sided tape is covered by parts 5,6 of the protective film, which in the shown embodiment are equally broad and whose combined width corresponds to the width of the tape 1.
  • Both the slot 9 and parts 5, 6 of the protective film are continuous in the longitudinal direction of the tape and extend to the edges of the tape.
  • the bearing layer of the tape is indicated with the reference numeral 10 in Figure 9.
  • the slot 9 may be replaced for instance by a weakening line or some other arrangement which makes it possible to remove the protective film in steps from the tape.
  • the tape need not be fixed exactly transverse to the paper webs, but often it is advantageous to fix it to the webs somewhat diagonally, as has been shown in the figures, whereby the impact on the printing roll is weakened.
  • the invention is particularly suitable for use in connection with thin and thick paper qualities, whereby the most suitable thickness for the bearing layer 10 of the tape is selected in view of the required tensile strength and the total thickness of the junction, but it can also be used in connection with other equivalent mater- ials.
  • the width of parts 5,6 of the protective film can be varied according to need.

Abstract

L'invention se rapporte à une méthode et à un ruban pour relier des bandes de papier. Lors de la production du papier, il peut arriver qu'une bande de papier soit déchirée ou coupée accidentellement, et dans ce cas les extrémités sont reliées au moyen d'un ruban. A l'endroit de la jonction connue, les extrémités des bandes se trouvent l'une sur l'autre, et un ruban à deux faces est placé entre celles-ci. Suite à des défauts de production, le papier ne recouvre pas toujours complètement le ruban, ce qui provoque le collage du papier par-dessus et par-dessous le point de jonction du rouleau, entraînant ainsi une rupture de la bande. On peut éviter cet inconvénient en utilisant un ruban à face unique (1) dont le film protecteur est divisé en deux parties (5, 6), ce qui permet l'utilisation d'un raccord bout-à-bout ne présentant aucun danger de collage.
