Abstract
A plant for manufacturing and packaging tubes feeds the tubes via a conveyor belt to a packaging station, where they are packaged to form larger units. The foil strip is a dual or multiple-strip, cut by at least one partitioning blade into individual webs respectively welded in parallel planes to form endless tubes and cut by transverse cutters. The tubular bodies are assembled into a larger transfer group and jointly transferred to a turn table including a corresponding number of mandrels. The turn table conveys them jointly and stepwise to stations for fitting the shoulder portion with a threaded neck and the closure cap. The finished tubes are deposited on a discharge belt and fed to control regions for checking. Flawless tubes are received by the discharge belt and fed continuously to a tray.
