Abstract
A method and apparatus are described for tag and thread assembly for tagged infusion packets. Spaced tags from a strip of tags and a length of thread are laid over each other on the periphery of a first assembly wheel and the thread is drawn out in loops between successive tags. The spaced tags and looped thread are transferred to a second assembly wheel where they are connected to a web of sheet material that is to form the infusion packets. The web is subsequently formed into a series of compartments in which infusion material is contained. The compartments are severed from the web for forming the individual packets and the thread is simultaneously severed between the packets.
