  • the present invention is essentially concerned with the problem of applying glue to paper webs, from which cardboard cores are then wound.
  • the paper web must be coated with the glue over its entire surface.
  • the invention can be used advantageously everywhere when a material web is to be coated with a coating.
  • the webs were previously coated by means of rollers or doctor bars with the adhesive. This often leads to loss of adhesive and set-up times are high when changing the web width, because on the doctor bar or the roller still adhering adhesive must be removed. If the adhesive is applied by means of rollers, in addition, high centrifugal forces act on the adhesive adhering to the roller, which increase quadratically with the roller speed. As a result, the web speed of the material web and thus the processing speed is limited. On this basis, the present invention is based on the problem, a
  • the device according to the invention is characterized in that the adhesive applicator is a nozzle bar.
  • this bar can always apply exactly the required amount of adhesive to the web. This results in a considerable adhesive savings. Since no centrifugal forces act on the adhesive, even large (almost any) web speeds can be realized.
  • the nozzle bar can be easily replaced without the need for previously cleaning the nozzle bar would be required.
  • the nozzle bar may be longer than the material web is wide, in which case only the area of the nozzle bar with the coating, so for example, the adhesive should be applied, which corresponds to the web width.
  • the length of the nozzle bar is adapted to the width of the material web. As a result, losses of material are reliably avoided, which saves adhesive while at the same time serving for cleanliness.

Both piston pumps 28 and 29 can be operated with their respective maximum pressure, which is then reduced by the respectively associated material pressure regulator 26 or 27 to a suitable material pressure for the subsequent coating of the paper web 10. Piston pumps namely have the known disadvantage that the pressure at the top and bottom dead center drops. This is smoothed by the material pressure regulators 26 and 27.

For this purpose, only the application head 13 is replaced by another, adapted to the current web width application head 13. For this only needs the clamping bar 15 to be solved. Then, the applicator head 13 removed and another application head 13 used and the clamping bar 15 are tightened again.

Abstract

L'invention concerne un dispositif permettant d'appliquer un revêtement, en particulier un adhésif, de préférence de la colle, sur une bande de matériau (10), en particulier une bande papier, de préférence pour produire des tubes de carton enroulés, le dispositif étant muni d'un dispositif d'application de l'adhésif et d'une alimentation (19) en adhésif. Les dispositifs de ce type connus entraînent souvent une perte d'adhésif et de longs temps de préparation en cas de changement de la largeur de bande. De plus, si l'adhésif est appliqué au moyen de rouleaux, l'adhésif adhérant aux rouleaux est soumis à des forces centrifuges élevées qui augmentent au carré avec la vitesse de rotation des rouleaux. Ceci limite la vitesse d'avance de la bande de matériau (10) et donc la vitesse de traitement. L'invention vise à éviter ces inconvénients. A cet effet, le dispositif selon l'invention est caractérisé en ce que le dispositif d'application de l'adhésif se présente sous la forme d'une rampe de buses (13).
