- the packaging 1 is placed on the plate 5, opening 10 directed downwards, in line with the slot 50 above the gripping station 3 and the support 31, and the label 2 is retained against the wall 40.
- the platform 30 rises until the support 31 comes into contact with the interior of the packaging 1.
- the platform 30 continues its ascent and the support 31 applies the bottom 12 of the packaging 1 against the label 2 and the wall 40.
- the wall 40 can also, according to a additional characteristic of the invention, moving towards the platform 30, in addition to or replacing the movement of the platform 30.
- the label 2 is indexed on the bottom 12 of the packaging 1.
- it is made by punching or spot welding, by means of at least one hot punch 41 passing through the wall 40, possibly also allowing marking of information on the label 2 covering the packaging according to an additional characteristic of the invention.
- the platform 30 descends, and deposits the packaging 1 on the bottom 12 of which the label 2 is indexed, on the platform 5, its edges 11 resting on the periphery of the slot 50.
- FIGS. 2A, 2B, 2C, 2D and 2E another part of the tooling making it possible to carry out the following steps of the method according to the invention can be seen.
- the tool comprises at a lower level a station 6 for gripping a package 1, at an upper level, vertical to station 6, a station 7 for securing the label 2, the plateau 5 always extending to the intermediate level.
- the station 6 comprises a platform 60, movable vertically, on which is arranged a support 61 of complementary shape to that inside the packaging 1, and in this case, in accordance with the entire packaging 1, that is to say coming into contact with the entire at least one peripheral wall 13, or at least the shape of the label to be applied to said packaging.
- the platform 60 and the support 61 are also of transverse dimensions smaller than those of the opening 50 so that during a vertical translation, the platform 60 and the support 61 can cross the plate 5 to take the package 1 which is in waiting.
- the gripping of a packaging 1 by the support 61 is advantageously completed by a suction system, represented by conduits 62.
- the securing station 7 comprises a set of means designed capable of receiving in close contact the exterior of the at least one wall 13 and of the bottom 12 of the packaging 1, in this case, it is a plate fixed 70 intended to serve as a support for the bottom 12, and movable plates 71 capable of being moved in the direction of the at least one wall 13.

- Figure 5 shows two installations 8 side by side, in the form of two carousels.
- the process of punctual attachment of the label 2 to the packaging 1 by punches 41 is not initially done on the bottom, but punctually on a first peripheral surface of the packaging 1, this surface and possibly other surfaces of the packaging 1 then being secured or sealed during the securing process, using suitable securing tools, in a suitable securing installation, to obtain a packaging decorated with a label on at least the first peripheral surface of the packaging, and optionally on said other surfaces of the packaging 1.
- the packaging 1 can be supplied with the opening directed upwards or to one side.
- the joining process can be done according to movements in opposite directions to those described above, in particular when the packaging 1 is supported by a support 61 of the platform 60 of the gripping station 6, and moved in the direction of the securing 7.
- the reversal of the packaging can also be only partial, the opening of said packaging then being oriented laterally.
