Abstract (en)

[origin: WO9403326A1] The invention relates to a process and device for making substantially cylindrical cardboard tubes, especially of wound cardboard, closed at one end. A revolving transfer machine (40) used to make these cardboard tubes has a rotary conveyor plate (41) and ten processing positions (I-X). Around, above and partly beneath the rotary conveyor (41) there are processing devices, e.g. a prepressing and presealing device (2), a sealing and rounding device (3), a smoothing device (4), a printer (5), a turning device (6), a gluing device (7) and a pre-bordering and post-bordering device (8 and 9) at distances corresponding to the angular distances between the stations (I-X). The cardboard tubes are vertically fed to the revolving transfer machine (40) in predetermined lengths and diameters via a supply device (1). The finished cardboard tubes are removed from the revolving tranfer machine by an ejector device (10). A stored-program control device (11) controls the entire production cycle.
