Abstract
An apparatus for making sealed packages from two superposed, sealable flexible wrapper sheets, has first and second convex support rings which are radially adjacent for guiding respective first and second wrapper sheets towards one another. First and second sealing discs are supported coaxially with the respective support rings at opposite sides thereof. The sealing discs form sealing disc pairs for longitudinally pressing and sealing together the wrapper sheets along opposite edge zones thereof to form longitudinal seams. There are further provided deflecting rollers situated upstream of the respective support rings for defining loop-around paths for the wrapper sheets on the respective support rings. Each support ring carries a shaping element for shaping the wrapper sheets immediately upstream of the sealing discs. The apparatus also has a sealing station for providing a transverse cutter for severing the sealed sheets into predetermined lengths whereby packages of defined dimensions are obtained.
