Packets and their manufacture

摘要

To form infusion packets (T) having a looped thread (8) within the packets to wring moisture from the packet in use, a continuous series of thread loops are formed on one elongate web of packet material and doses of infusion material are placed on a second elongate web of packet material before bringing the webs together with the thread loops and infusion material between them. The two webs are then welded together and the individual packets are separated from the joined webs.
