  • Patent number: 5871789
    Abstract: A machine and process for making complete tea bags comprising a filter bag and thread for holding the filter bag. The machine comprises a continuously turning wheel, whose lateral surface has pins which can move from a rest position, where they are retracted into the lateral surface, to a working position where they protrude from the wheel; the wheel assembles a strip of porous material with the thread, with a pickup tag and with the infusable product in such a way as to form tea bags where the thread is arranged in a closed loop inside the filter bag, together with the infusable product, and is attached to the edges of the filter bag to form a particularly resistant fastening during infusion.
