- the position of the cutouts thus produced is then adjusted with respect to the cups 9 formed on the lower filter paper sheet 2.
- the reinforcing strip 24 is then interposed between the two sheets of filter paper 2, 3 and then they are assembled.
- the step of superimposing the reinforcing strip 24 and the lower filter paper sheet 2 is carried out before depositing the dose 4 of the product to be infused 5.
- the reinforcing strip comprises two faces covered with a thermoplastic film so as to be able to assemble it to the sheets of filter paper 2, 3 by heat sealing.
- a lower sheet of filter paper 2 is brought in by feeding means 6.
- a reinforcing strip 24 is used, this is also brought in by means 25 which may be of similar design. .
- the reinforcing strip 24 undergoes cuts 27 by means of cutting means 26.
- the reinforcing strip 24 and the lower filter paper sheet 2 are then substantially superimposed.
- the filter paper sheet 2 is driven at a slightly higher speed with respect to the reinforcing strip 24. It then loosens as shown in FIG. 3 before the assembly step.
- the bowls 9 are then formed on the surface of the lower filter paper sheet 2.
- the assembly is carried out in particular by heat-bonding the sheet of filter paper 2 and the reinforcing strip 24. The advance of this assembly then continues towards the means capable of depositing a dose 4 of product to be infused 5.
- This deposition is carried out by the evacuation of a quantity of product to be infused 5 into a receiving hole 14 formed on a drawer 12.
- This drawer 12 then undergoes a translational movement towards an ejection zone where the dose 4 will be deposited in the bowl 9.
- the assembly 10 is lowered for ejection of the dose 4 near the bowl 9.
- a sheet of pods 1 is thus formed which can be used after cutting. This cutting can be performed after the steps described above to form individual pods. As has just been described, pods 1 are produced in series and aligned in the direction of movement of the installation.
- Figure 2 shows the realization of four pods in parallel.
