1. A method for the high-speed packaging of pre-formed filter bags (1) containing metered quantities of an infusion product, comprising at least three steps, in the first of which the filter bags (1) are wrapped in a protective tubular envelope (2) formed by a longitudinal seal (5) and a transversal seal (6) making a flattened tube from a continuous strip (3) of envelope (2) material folded into a V shape with wings (4) between which the filter bags (1) are suitably placed at regular intervals from each other;

  • in the second step, the tube being cut into predetermined lengths, each containing one filter bag (1) wrapped in an envelope (2); and

    in the third step the filter bags (1), wrapped in the envelopes (2), being placed in cartons;

    wherein the transversal seal (6) is made in two successive steps as the continuous folded strip (3) moves through two separate consecutive sealing stations (7, 8), the first station (7) making a part of the transversal seal (6) and the second station (8) completing the rest of the same transversal seal (6).
