Patent ID: 8826633

Claim:
A method of producing packs ( 10 ) for cigarettes, the packs ( 10 ) having an outer pack ( 12 ) configured as a hinge-lid box, and an inner pack ( 13 ) as a sealed block ( 25 ) with an inner blank ( 26 ) which encloses the pack contents, and is made of aroma-tight and moisture-tight, thermally sealable sheet material, the inner pack having, in the region of an inner end wall ( 33 ), an opening aid which is usable a number of times and, in the region of side walls of the inner pack ( 13 ), folding flaps which are connected to one another by thermal sealing, the method comprising: a) conveying the pack contents, by the inner blank ( 26 ), into the pocket ( 64 ) of a folding turret ( 65 ), with the pack contents being wrapped partially in the inner blank ( 26 ); b) connecting folding flaps ( 108 , 109 ) in the region of an inner rear wall ( 34 ) of the inner blank ( 26 ) to one another by thermal sealing to form a fin seam ( 37 ) in the folding turret ( 65 ), in a plurality of successive sealing stations ( 78 ), which are arranged on the circumference of the folding turret ( 65 ), while the cyclically driven folding turret ( 65 ) is at a standstill; c) folding end regions of the fin seam ( 37 ) over into the plane of inner side walls ( 35 ) in such a way that they are arranged at a spacing (A) from regions of folding flaps which cover one another multiple times, in the region of the inner side walls ( 35 ); d) during feeding of the pack contents into a pocket ( 64 ) of the folding turret ( 65 ), placing a folding flap ( 108 ) of the inner blank ( 26 ) for the fin seam ( 37 ) against a sealing bar ( 77 ) which is assigned to the pocket ( 64 ) by way of a pusher nose ( 82 ) which is formed on a pusher ( 63 ) for the pack contents, and is held there by vacuum by at least one suction channel ( 83 ), wherein the sealing bar is arranged laterally next to the pocket ( 64 ) and at a spacing from the circumference of the folding turret ( 65 ); e) guiding a further folding flap ( 109 ) for the fin seam from the circumference of the folding turret ( 65 ) through a sealing jaw ( 79 ) of a sealing station ( 78 ) to the sealing bar ( 77 ); and f) sealing the further folding flap with the first folding flap ( 108 ) by the application of pressure and heat to the fin seam ( 37 ).
