Abstract

Blanks are produced from a continuous sheet (3) of material comprised of plastic-coated paper. Said blanks are conveyed on an expanding mandrel carousel (13) to a bottom weld flap forming station (17) and then transferred to a filling carousel (19). The packages which have been formed from the blanks are filled at a filling station (20) and sealed at a top seam welding station (23). A top weld flap forming station (26) and a top weld flap sealing station (29) are disposed on a top forming carousel which adjoins the filling carousel (19). The finished packages are discharged at a discharge station (30), to a discharge turntable (31). The machine may be used for manufacturing packages for liquids, e.g. milk or juices.
