  • the tab of opening 5 includes an anchoring portion 6 welded or glued to the outer face 7 of the film 2, covering the incision 3, and a gripping portion 8 allowing the user wishing to open the packaging to grasp the tongue d 'opening 5.
  • the orientation and location of the incision 3 on the film 2 and relative to the object 1 are not important in the context of the present invention and can be arbitrary.

In this way, this gripping portion 8 is not permanently bonded to the film 2 and can be easily gripped by the user with a view to opening the packaging.

  • the entire labeling system is mounted relative to the frame 20 on a common support whose vertical position relative to the plate 34 of the conveyor 21 is adjustable, for example using a crank console, worm and slide, similar to that allowing the adjustment of the upper conveyor 39. In this way, it is possible to adjust the position of the plate 43, in particular of its end portion 56 relative to the lumen 44 and to the packaged articles 1.
  • the different packaged articles 1 follow one after the other, with a spacing between them sufficient to allow the functioning of the detectors 24, 25 and of the stations 22, 23 for cutting and laying.
  • a single incision 3 is therefore made through the film 2, giving it the shape of a straight portion and the opening tab 5 is placed and oriented on the film 2 with its gripping portion 8 which extends the anchoring portion 6 in a direction at least substantially perpendicular to the main direction of the incision 3.
  • the steps of cutting the incision 3 and installing the opening tongue 5 are carried out successively on packaged objects or groups of objects 1 which are driven in continuous movement without interruption, in translation in a direction at least substantially perpendicular to the main direction of the incision 3.
