Definitions

  • the invention relates to a glue basin for an edge gluing machine with a glue head, the interior of which is via an outlet slit opens to the outside, and one outside the Glue head in front of the outlet slot arranged application roller, being between the applicator roller and the exit slot a rotatable metering rod is arranged.
  • the glue flows e.g. from a parent funnel with Gravity down.
  • Glue pools are known from the prior art, in which the glue is fed to the glue head from above by gravity becomes.
  • These glue tanks usually have one Applicator roller with a dosing stick for dosing the adhesive rotating application roller. If the roller both for one turn in synchronization with the direction of movement of the workpiece and also designed for a rotation in the opposite direction to this it is known to provide two metering rods. A leak of the adhesive when the roller is stationary by applying a dosing edge of the corresponding dosing rod directly the application roller prevented.
  • the application roller and the metering rods thus form a constructive together with the glue head Unit that is difficult and only by specialist staff to be dismantled. This is especially so when using it of adhesives that require increased cleaning and maintenance bring with them, such as with reactive PUR adhesives, a big disadvantage.
  • the invention has for its object with constructive simple means to create a glue pool where a The adhesive runs out regardless of the application roller It prevents standstill and an exact dosage of the adhesive enabled during operation with a high degree of automation becomes.

  • the hopper 12 For applying thermoplastic adhesive to the workpiece 80 the hopper 12 is filled with adhesive granules, that too enters the glue head 16. Then the funnel 12 and the glue head 16 heated to a suitable temperature, so that the glue inside the glue head 16 as well as the glue is melted in the hopper 12. Doing these two Zones defined by the control devices Program heated up and kept at the appropriate temperature. The glue head 16 is always completely filled with glue and therefore always has a defined amount of adhesive. In the funnel 12 is a different fill level depending on the refill interval available.
