Patent

CA 2038691

Twin compartment packets, eg. tea bags, are formed with the compartments connected at the heads of the packet and optionally at the tails. The packets are produced from a pair of compartmented tubular webs that are brought together with the compartments in register, the webs then being interconnected at the compartment end seals and severed at those seals to form the separate packets. Apparatus for performing the process deposits doses of tea at spaced intervals onto the two separate webs before forming them into the tubular compartmented webs, brings the compartments of the two webs into register, interconnects the registered compartments, and separates the interconnected compartments into individual packets while the web advances continuously through the apparatus. The process is capable of high production rates because the webs are able to move through the successive stages at a uniform speed.
