Abstract
Plural strips of package making sheet material are directed toward a forming and filling tube in a form, fill and seal machine for making packages, and the strips are guided into cooperative relation along the tube for joining of the strips into tubular form about the tube. In a preferred arrangement, the strips are derived by slitting a continuous single sheet of package making material, provided with complementary zipper profiles along the slit margins of the strips. A three-bar guidance system is provided for guiding each of the strips cooperatively to the forming and filling tube.
