Method and device for producing packs from at least two partial packs
The invention relates to a method for producing packs ( 23 ) from at least two partial packs ( 25, 26 ) to form one groups of packs ( 21, 22 ) each of especially cuboid (cigarette) packs ( 20 ), a one-piece blank ( 24 ) being folded along (embossed) fold lines ( 46, 47 ) around the groups of packs ( 21, 22 ) in such a way that mutually facing inner walls ( 27 ) of the partial packs ( 25, 26 ) are folded in between the groups of packs ( 21, 22 ) in a V shape. According to the invention, the substantially flat blank ( 24 ) is conveyed along a blank path ( 36 ) and, during the transport, is at least partially upset in such a way that the inner walls ( 27 ) are folded in a V shape along fold lines ( 46 ) arranged transversely with respect to the transport direction. The invention also relates to a corresponding device for carrying out the method.
1. A method for the production of cartons ( 23 ) comprising at least two partial cartons for groups of packs ( 21 , 22 ) for cigarettes, comprising the steps of:
transporting a one-piece blank ( 24 ) along a blank path ( 39 );
while along the blank path ( 39 ), holding the blank ( 24 ) in a blank path plane using guides ( 45 ), and
during the transporting step, the blank ( 24 ) contacts a stop ( 44 ) and is at least partially buckled along fold lines ( 46 , 47 ) to form the partial cartons such that mutually facing inner walls ( 27 ) of the partial cartons are folded in a V shape along the fold lines ( 46 ), inserting the groups of packs ( 21 22 ) such that the inner walls ( 27 ) are folded between the groups of packs ( 21 22 ) and folding the blank ( 24 ) around the groups of packs ( 21 22 ),
wherein the fold lines ( 46 ) are arranged transversely to the direction of transport, and
wherein the inner walls ( 27 ) are not held in the plane of the blank path ( 39 ) by the guides ( 45 ) and pivot out of the plane of the blank path ( 39 ) into the V-shape.
2. The method as claimed in claim 1 , wherein the groups of packs ( 21 , 22 ) have cigarette packs ( 20 ) arranged in layers and are transported toward the V-shaped fold and the partly folded blank ( 24 ) such that the inner walls ( 27 ) of the blank ( 24 ), which have been formed in a V shape by the buckling, come between the layers of the group of packs ( 21 , 22 ).
3. The method as claimed in claim 2 , further comprising the step of:
following the transporting of the groups of packs ( 21 , 22 ), folding the blank ( 24 ) into a U shape around the groups of packs ( 21 , 22 ) by continuing the transport of the groups of packs ( 21 , 22 ).
