A method and a machine for assembling a blister sheet and a linerboard, the board optionally having a flap. The blister sheet, the linerboard and the optional flap are flat stacked on top of one another; and the layers are subsequently heat sealed, preferably by means of thermal conduction or induction between a counter electrode and an electrode, continuously and in respective closed circuits, in order to produce cases for packaging such items as medicaments, electronic components, small tools, perfume samples or any other product which is to be enclosed in at least one bubble of the blister sheet.

The invention claimed is: 1. A method of assembly between: a blister sheet having two plane main faces and comprising at least one product containment blister projecting on a first of said main faces, and a linerboard having two plane main faces and having at least one hole for the passage of said blister, the blister sheet and the linerboard being capable of occupying a defined relative position, in which a first of said main faces of the linerboard is laid against the first main face of the blister sheet, around the blister, and at least one of the first main faces being thermoadhesive or being made thermoadhesive, said method comprising: a) placing the blister sheet and the linerboard in said defined relative position, b) applying to the blister sheet and to the linerboard, which occupy said defined relative position, a pressure for the mutual clamping of their first main faces and a treatment capable of making adhesive said first main face which is thermoadhesive or is made thermoadhesive, for the time necessary for bringing about a mutual thermoadhesion of said first main faces, c) causing the application of said pressure and said treatment to cease, wherein steps b and c are carried out by causing a succession of individualized blister sheets and of linerboards, placed in said defined relative position during step a, to travel jointly and continuously, said step a itself being carried out continuously, wherein step b is carried out by a means selected from the group comprising induction and thermal conduction, wherein a plurality of electrodes and a plurality of counterelectrodes are circulated continuously in a respective closed circuit, said closed circuits comprising a common limited portion, along which the electrodes and counterelectrodes follow a common path, at the same time being matched in a defined relative position in which they offer a respective plane face toward one another, between an entrance, at which the electrodes and counterelectrodes approach one another, at the same time circulating along said respective closed circuit, and an exit, at which the electrodes and counterelectrodes move apart from one another, at the same time circulating along said respective closed circuit, and wherein step b is carried out by introducing a blister sheet and a linerboard, placed in their said defined relative position during step a, between a mutually corresponding electrode and counterelectrode at the entrance of said common path, and by causing the blister sheet and the linerboard, placed in their said defined relative position, to execute said common path between said mutually corresponding electrode and counterelectrode, as far as the exit, at which the mutual spacing apart of said mutually corresponding electrode and counterelectrode carries out step c. 2. Method as claimed in claim 1, the linerboard comprising a flap having a first main face initially placed in the extension of the first main face of the linerboard and, in said defined relative position, occupying a turned-down position in which its said first main face is laid against the second of said main faces of the blister sheet, and at least the first main face of the flap or the second main face of the blister sheet being thermoadhesive or being made thermoadhesive, wherein the flap is placed in said turned-down position, during step a, after the first main faces of the linerboard and of the blister sheet have been laid against one another, and wherein step b is carried out when the flap occupies said turned-down position, in such a way that said mutual clamping pressure likewise forms a pressure for the mutual clamping of the first main face of the flap and of the second main face of the blister sheet, and in such a way that said treatment likewise makes adhesive said main face of these main faces which is thermoadhesive or is made thermoadhesive, said time being selected in such a way that it is sufficient likewise in order to bring about a mutual thermoadhesion of the first main face of the flap and of the second main face of the blister sheet. 3. The method as claimed in claim 1, wherein the blister sheets and the linerboards are caused to travel along a curved path during step b. 4. The method as claimed in claim 1, wherein one of said plane faces has at least one cell for receiving a blister, and in that step b is carried out so as to engage the blister in said cell. 5. The method as claimed in claim 1, wherein the counterelectrodes are caused to execute, upstream of said common path, an upstream path along which their said face faces upward, and in that they are used, along this upstream path, as vehicles for a respective blister sheet and respective linerboard during the carrying out of step a. 6. The method as claimed in claim 5 wherein the counterelectrodes are produced or selected in such a way that they have respectively a cell, and in that step a is carried out by successively depositing, flat, the linerboard with the second of its said main faces on said face of a counterelectrode, said hole being placed in register with said cell, and the blister sheet with its first main face on the first main face of the linerboard, said blister being engaged in said hole and, through the latter, in said cell, then, if appropriate, with a contingent flap of the linerboard being folded in order to bring it from its initial position into its turned-down position. 7. The method as claimed in claim 1, wherein the counterelectrodes are caused to execute, downstream of said common path, a downstream path along which their said face faces upward, and in that they are used, along this downstream path, as vehicles for a respective mutually assembled blister sheet and a respective linerboard. 8. The method as claimed in claim 1, wherein the closed circuit of the electrodes is circular, and in that the closed circuit of the counterelectrodes is in the form of an arc of a circle coaxial to the closed circuit of the electrodes along said common path. 9. The method as claimed in claim 2, wherein the blister sheets and the linerboards are caused to travel along a curved path during step b. 10. The method as claimed in claim 4, wherein the counterelectrodes are caused to execute, upstream of said common path, an upstream path along which their said face faces upward, and in that they are used, along this upstream path, as vehicles for a respective blister sheet and respective linerboard during the carrying out of step a. 11.
