  • Former for a packaging machine to form pairs of three side sealed pouches from packaging foil material
    Patent number: 6813871
    Abstract: The present invention relates generally to pouches, and more particularly to a former to form pairs of dispenser pouches of the flexible three-sided sealed type. The former has a continuous foil channel and outer guide surfaces for a foil strip to be reshaped into a double tube, which enters the channel through a foil supply edge. A pair of form- and filling pipes are arranged in the channel, which has a back wall, two front walls having two form edges, and sidewalls that are adapted to the cross-section form of the filling pipes. The wedge-shaped form edges of the front walls delimit a slit in the lower part of the former. The back wall and the form edges of the front walls, proceeding from the foil supply edge and a section that converges in continuous direction between the front walls, are developed relative to one another and continually approaching until the end of the downwardly open slit.
