ABSTRACT:
An apparatus for continuously producing a series of multi-compartment packages formed from a single web of pliable film material. The machine folds the web along one of its side edges to form a pocket or two-ply margin. The web is then passed through a tube former which bends the web across its width until a continuous tube is formed with the two-ply margin to the inside and overlapped by the opposing side edge of the web. The apparatus then seals the tube with a single composite seal across the overlapped portion of the tube, which is of three-ply thickness. Next, the apparatus positions differing substances in each compartment. Then, the apparatus sequentially gathers the filled tubular member at two positions along its length, seals the gathered portions by clinching pairs of closure clips therearound, and severs the film material between the clips in each pair thereof to form the package.
