Definitions

  • the present invention relates to a device for spread ⁇ ing jointing adhesive on a paper surface, said device comprising a rotatable adhesive spreading roll, norm ⁇ ally closed nozzles on the periphery of said spread ⁇ ing roll, said nozzles being connected via closed adhesive supply passages to an adhesive supply means and the shut-off means of said nozzles being adapted to open by the action of an external pressure while the spreading roll is rotating.
  • a device of this type is disclosed in FI Patent public ⁇ ation 49779.

Production rate is limited since the increase of speed leads to more splashing of glue. Also the repeated need for washing lowers efficiency. Scrapers that are worn out or out of order let through lumps of glue leading to improper joints and increased adhesive consumption.

Abstract

Le dispositif comprend un certain nombre de rouleaux pourvus d'ajutages d'adhésif (20), ces rouleaux étant agencés pour la fabrication de sacs en papier multicouches de sorte qu'une pluralité de rouleaux d'étalage allongés dans le sens axial (E), pourvus d'un réseau d'ajutages s'étendant axialement à la périphérie, sont disposés en parallèle et adjacents entre eux pour réaliser des joints transversaux sur des bandes de papier qui composent les différentes couches. Sur la même ligne se trouve un rouleau d'encollage axialement court (C) dont la périphérie est pourvue d'un réseau circonférentiel d'ajutages d'adhésif produisant un joint en longueur pour la fabrication de tubes. En aval de la station de pliage des volets de fermeture de fond est disposé un ou plusieurs rouleaux d'encollage (A, A1) pour les volets de fermeture de fond, et en dernier, sur la ligne, se trouve un rouleau (D) produisant des joints adhésifs permettant le collage d'un volet de fond.
