ABSTRACT:
An apparatus for closing a package around an article to be packaged by folding one or a plurality of closing flaps (3, 4) around the open side of a package. The apparatus comprises a conveyor track (13), first folding means (32) which are movable crosswise of the conveyor track, holder and pusher means (22) mounted below folding means (32) and movable crosswise of the conveyor track, a first conveyor track section followed by a second conveyor track section (13), the latter being vertically liftable and lowerable, and press means (8, 18) mounted above the second track section and vertically liftable and lowerable. Said folding means (32) are adapted to be movable together with holder and pusher means (22) and, in addition, relative to holder and pusher means (22). Above the first conveyor track section are means for positioning and measuring of the width of an arriving package. The folding means (32) as well as holder and pusher means (22) are adapted to be advanced to the initial folding position on the basis of the measured width. Along one side of the second track section (13) there is a second folding means (7) defining a vertically adjustable gap through which said (22) force a package while the first folding means holder and pusher means (32) are bearing against the top surface of a package. The closed package is carried away from the apparatus between conveyor belts (8, 9), the adhesive having time to set while a second package can already be closed and the width of a third one can be measured.
