Definitions

  • the invention relates to a device for uniformly wetting a flexible strip such as a strip of paper or any other flexible support previously glued commercially, used for franking letters, packages and parcels, for packaging and labeling.
  • the upper part of the brush, wetted with liquid by capillary action, is kept in contact with the glued side of the labels during their movement in front of the brush. If this brush has a better resistance over time than a sponge or a felt, it has the disadvantage of not regularly distributing, over time, the wetting liquid on the glued side of the labels because it is loaded accidentally glue. Indeed, the scraping of the glued side of the labels on the ends of the brush wires causes a deposit of glue between the brush wires. This results in a fouling phenomenon of the brush due to the fact that the adhesive remains trapped between the wires of the brush without the possibility of being removed during the movement of the labels. This results in poor transfer of wetting liquid to the labels, certain parts of the adhesive side of the labels being washed, and the result is that the wetting of the labels is not uniform over time.
  • the object of the invention is to provide a device for wetting a flexible strip comprising a wetting element which does not have the aforementioned drawbacks.
  • the subject of the invention is a device as defined in claim 1.
  • Such a rigid wetting element is not subject to wear. It is also not subject to fouling because the orientation of the capillary slots along the direction of travel of the flexible strip allows continuous removal of adhesive residues during the travel of the strip, by channeling the wetting liquid in the capillary slots. The wetting of the flexible strip, in the form of parallel bonding lines, remains uniform over time.
  • the bar is provided at its upper part with grooves parallel to the capillary slots and arranged between them to evacuate an excess of wetting liquid.
  • the bar is removably mounted to be removed from the tank if necessary.
  • the bar is made of a thermoplastic material for example injected which makes it simple to manufacture and therefore inexpensive.
  • the device for wetting a flexible strip also comprises a member for guiding the flexible strip mounted above the rigid bar for applying the strip under pressure on the upper part of the bar, this guide member being provided with a plurality of ribs facing the upper part of the bar, each rib extending parallel to the capillary slots without facing them. This position of the ribs relative to the capillary slots makes it possible to guide the flexible strip properly while preserving a good quality of transfer of the wetting liquid to the flexible strip, that is to say without inadvertently wetting the unglued side of the flexible strip.
  • each rib faces a groove so that the pressure band of the flexible strip is applied to the bar in places where there is no transfer of wetting liquid to the flexible strip so as not to damage it. .
  • Figure 1 is a schematic front view, cut tank, of the device according to the invention.
  • FIG. 2 is a schematic sectional view along II-II of FIG. 1.
  • Figure 3 is a perspective view of the rigid bar according to the invention.
  • the device 1 for wetting a flexible strip such as a paper strip 2 having an at least partially glued side, such as a label comprises a tank 3 in which is placed a rigid bar 4, of substantially paralleleliped shape having its upper part projecting from the opening of the tank.
  • the rigid bar 4 rests on studs 5 secured to the bottom of the tank and is held to these by means of pins 6 fixed to the studs 5 and coming to be forced into recesses 7 arranged in the lower part of the bar.
  • the rigid bar is removably mounted so that it can be removed from the tank if necessary.
  • the strip of paper conventionally driven by a set of rollers and counter-rollers (not shown) scrolls above the bar in a direction of travel and a direction represented by the arrow f, the direction of travel of the paper strip being perpendicular to the longitudinal axis of the bar in place in the tank as shown in Figure 2.
  • the previously glued side of the paper strip faces the upper part of the rigid bar and comes flush with it.
  • the upper part of the bar is crossed, in the direction of travel of the paper strip, by a plurality of capillarity slots 8 substantially parallel to each other visible in FIG. 3.
  • Each capillary slot 8 opens onto the top face, the front and back of the bar.
  • slots opening only on the top face and the rear face of the bar right side of the bar visible in Figure 2 to obtain the same effect.
  • the tank 3 is filled with a wetting liquid such as an adhesive dilution liquid such as for example water, the level of which is kept constant by any suitable means as described in patent application EP 0293316, so that the bottom 9 of the slots continuously bathes in the wetting liquid.
  • a wetting liquid such as an adhesive dilution liquid such as for example water
  • the comb-shaped bar can be made of an injected thermoplastic material capable of bringing capillarity the wetting liquid from the bottom of the capillary slots to the upper face of the bar. It is placed transversely to the path of advance of the paper strip so that the upper part thereof, wetted by said liquid by capillary action, forms bonding lines on the glued side of the paper strip, these lines of bonding being substantially parallel to each other and to the direction of travel of the paper strip.
  • the number of slots and grooves may vary depending on the width of the paper strip.
  • the speed of movement of the paper strip, the height of the level of adhesive dilution liquid relative to the bottom of the through capillary slits and the width of these make it possible to vary the amount of water deposited on the face glued with the paper strip.
  • a member for guiding the paper strip consisting of an upper part 12 and a lower part 13 is fixed to the tank 3 by fixing screws 14, 14 ′ respectively, these two parts being arranged on either side of the paper strip 2.
  • the upper part 12 of the guide member which is mounted above the paper strip, for the pressure application of the paper strip on the upper part of the bar is provided with a plurality of ribs 15 facing the upper part of the bar 4.
  • Each rib 15 extends parallel to the through capillary slots 8 without facing them and preferably facing them screw of a groove 10.
  • the upper part 12 of the guide member can also be hinged to be able to pivot between a first position where it is positioned above the paper strip for its application under pressure on the part upper part of the bar and a second position where it forms a deflector preventing the strip of paper from coming flush with the upper part of the bar.
