A method for closing a filter bag for an infusible product, and for connecting a thread having a tag to said filter bag, comprising:
- providing a filter bag, having at least a lobe, at least a flap folded to prevent the filter bag from opening and the infusible product from going out,
- providing a connecting thread, having a first terminal portion at a first end and a second terminal portion at its end opposite the first end,
- providing a pickup tag,
- placing at least two sections of the first terminal portion vertically adjacent each other on opposite sides of the flap,
- providing stitching means for locking said flap in a predetermined position, simultaneously fixing the first terminal portion of said connecting thread to said filter bag, by engaging an upper portion of said filter bag in the region of said flap with a portion of a first auxiliary thread made of a natural fiber, forming a short stitch, simultaneously engaging the at least two adjacent vertical sections of the first terminal portion, with the first auxiliary thread.
