Abstract
For the heat treatment of cigarette packs (10) having an outer wrapper made of shrink film, the packs (10) can be conveyed in pairs, one above the other, through a shrink-fitting subassembly (20). During a standstill phase, heating plates (22, 23, 24) butt against upwardly and downwardly oriented pack surfaces in order to transmit heat. The heating plates (22, 24) can be moved upward and downward in order that the pack (10) is free of loading during the conveying cycle.
