ABSTRACT:
An apparatus is provided for folding and sealing the longitudinal end flaps of cigarette packs. The folding is performed by means including a rotating turret having a number of radially external pockets each adapted to receive a pack. The pocket axes extend parallel to the turret axis and the pockets are open at their ends, where the end flaps which project in the intermediate folding position project out of the pocket. Folding and sealing shoes are associated with each pocket and are mounted on both sides of the turret for both radial and axial movement. Due to this movement the folding and sealing shoes first fold inwardly the longitudinal end flap--which is positioned radially inwardly relative the turret axis and which has a closure strip, in such a manner that the closure strip engages with the inside of the opposing longitudinal end flap. The shoes then apply the required pressure in the direction of its movement so that the closure strip is pressed on to the opposing longitudinal end flap, the back of which is supported by an abutment. The side end flaps are then folded by folding means applying lateral pressure.
