Definitions

  • a controllable glue printer can also be provided for applying the glue to the back of the labels or for indirectly applying glue to intermediate pallets.
  • the glue can be applied in a variable glue pattern by means of the controllable glue printer directly to a contact surface of the pallets or a glue application surface of the labels.
  • the volume flow of glue through the supply line is continuously or periodically determined during operation of the labeling machine, the supply of glue being regulated as a function of the determined volume flow.
  • the feed device and in particular the amount of glue it emits per unit of time, is regulated in such a way that glue is emitted by the glue application unit at a constant flow rate or a constant volume flow. This can be done, for example, by means of a control unit, which is equipped with a flow measuring device and the controllable Feed device is connected.
  • the storage container can, however, also be arranged between two opposing punches or rollers, of which at least one / one is displaceable relative to / to the other.
  • two opposing rollers or wedges can be provided, between which the storage container is pulled or pushed through like a tube to be spread out. The relative movement therefore does not necessarily have to lead to a change in the distance between the storage container and the deformation element. Rolling out a storage container by longitudinal displacement is also conceivable.
  • the control unit can control both the piston movement in the dosing cylinder and the removal device in such a way that a continuous delivery of glue at the desired flow rate through the glue application unit to the labels can be guaranteed.
  • production can be temporarily interrupted in order to refill the dosing cylinder by conveying glue from the storage container.
