  • said gluers 30 are taken again in a position of non interference, while after having obtained this position, the further rotation of the wheel 6 controls the oscillation in the closing position of the oscillating wall 505, the progressive displacement of the retaining flap in an external position with respect to the housing pocket when the lateral walls 105 progressively overturn inwards carrying the flaps A2 provided with glue against the gluing flaps A1.
  • said tab L5 cooperates with the curved surface of the central rib 905 of the front wall 305 causing the curve of the tab 15 whose free edge is oriented towards the inside of the pocket and thus in such a way to enter behind the U-shaped frame of the area L3 that forms the front side of the package by means of the end part of the central rib 905 forming the front wall 305 of the housing pocket 5 and projecting inwardly of said pocket beyond the plane of the two lateral ribs against which the area L3 is retained forming the front wall of the package.
  • FIG. 27 This is shown in more details in figure 27.
  • the method according to the invention for making packages Firstly, in opposition to the manner to form a package from a flat, shaped element, according to the present invention, the foldings of the plurality of said flat, shaped element are all carried out in a single station. Secondly, the plane shaped element is folded on a mold by means of folders performing a rolling movement along the surface of the flat, shaped element.
  • Another advantage is the particular manufacturing of the housing pockets that are composed of walls substantially corresponding to the package walls and that are oscillating with respect at least to a stationary wall, particularly two stationary walls that is the bottom side and the rear wall.
