Abstract
The performance of packaging machines for the production of hinge-lid cigarette packs is limited by complex folding operations. In particular, these packs have hitherto been conveyed through the packaging machine by intermittently moved conveying members (folding turrets), the necessary folding steps thereby being carried out. In order to increase the performance of a packaging machine of this type, folding turrets (35, 36) are driven continuously. During the continuous movement of folding turrets 35, 36, the necessary folding of pack blanks (12) are made, especially by means of co-rotating folding members assigned respectively to a pocket (47, 74) of the folding turrets. During the continuous run, partially finished hinge-lid packs (10) are transferred from one folding turret (35) to the following folding turret (36) which is designed in a similar way to the first folding turret (35) and which completes the folding of the pack blanks (12). To increase the performance even further, the packaging machine is operated in a two-track mode with folding turrets (35 and 36) designed as double turrets.
