  • the axis A is formed by journalling the ends of the swinging arms 3b to supporting pieces 5 fastened to the guide boom 1 .
  • the movement of the carriages 2 turning the tapes T to the running direction of the web, and the swivelling movement of the transfer means 3 moving the gripping ends of the tapes, are independent from each other.
  • the movement of the carriages 2 along the guide boom 1 for the tapes is guided by threaded rods 1 a which extend in the longitudinal direction of the guide boom 1 , each threaded rod being engaged with the respective carriage 2 by a threading in the through-hole of the carriage, the other through-holes allowing the free rotation of the other rods.

  • the foremost end of the tape is fastened to the slide pad 6, in a slit 6a on its front side (the side on the run- ning direction of the webs) by bringing it over the slide pad 6 and through the slit to the rear side of the slide pad.
  • the tape T remains fastened to the slide pad 6 when it is pulled backwards in the direction opposite to its introduction, but it is released when one of the two cardboard webs, against which web the gripping end T1 is pressed, pulls it in the opposite direction, that is, in the running direction of the cardboard web.
  • an adhesive piece 7 is fastened to the tape T, whose adhesive surface faces that surface of the cardboard web in the gap between the cardboard webs, onto which the end of the tape is to be fas- tened.
  • the adhesive piece 7 comes between the slide pad 6 and the tape, with the adhesive side fixed onto the tape T and facing away from the slide pad.
  • the adhesive surface of the adhesive piece 7 forms the area at the gripping end T1 of the tape, by means of which the tape adheres to the surface of the cardboard web.
  • Figure 5 also shows how the second end of the slide pad 6 is introduced to the inside of the beam through a slit 3c extending in the longitudinal direction of the beam behind the transverse beam 3a,. Similarly, the figure shows how the slide pad 6 is partly off the transverse beam 3a in the area where the tape T is provided with the adhesive piece 7. In this way, the slide pad 6 can yield towards the beam 3a, if necessary, in a situation of fastening the gripping end T1 , for example because of the movement of the cardboard web.
  • the best springness properties are obtained is the slide pad 6 is made of spring steel.
  • the figure also shows how the horizontal roller 2b of the carriage 2 acts during the swivelling movement as a deflector roller for the tape coming from below.
  • the tape T is sufficiently slack to be carried along with the web W1 without being hindered by the beam 3a.
  • the transfer means 3 is returned to the standby position. Because the rotation axis A of the transfer means 3 is fastened above the carriages 2, a large movement range is pos- sible with the swivelling movement upwards
  • Figure 6 also shows the lower web W2 which runs below the guide boom 1 and will later join the upper web W1 , wherein the gripping ends T1 adhered to the lower surface of the upper web 2 and the tapes T following them are trapped inside the cardboard web with a layered structure. It is also possible to place the transfer means 3 so that the gripping ends of the tapes are pressed and attached to the lower web W2, for example by means of a similar swivelling movement around an axis A as described above. The device fits well in the gap between the cardboard webs and does not take too much space. The extent of the swivelling movement of the transfer means can be adjusted to various gap dimensions in different machines.
  • the fastening of the tape grip- ping ends to one of the cardboard webs to be joined can be performed with a single transfer movement by swinging the transverse beam 3 in such a movement range with respect to the rotation axis A that the gripping ends hit the web, adhere to it, and are disengaged from the transverse beam 3a.
  • the tapes come to the correct locations in the transverse direction of the cardboard web.
  • the slide pads 6 can be positioned manually at the respective carriages 2 which have been transferred on the basis of position data input in the control unit 4, because this positioning accuracy is sufficient for starting the feeding of the tape.
  • the transfer movement can also be implemented with a linear movement, by providing, for example, the transverse beam 3a to be movable linearly towards one of the two cardboard webs by a suitable mechanism.
  • a suitable mechanism can be arranged in the tape guide boom 1 used as the supporting frame, and it can be moved by a motor.
  • the invention can be applied, for example, in a corrugated board machine for manufacturing packaging material, in which continuous tapes are to be placed, which will later have a function in the finished package, for example as a reinforcement or a tear-off tape.
  • the tape can be a band or tape which is equipped with hot melt adhesive on its surface and which will finally be fixed by heat inside the cardboard.
