Patent number: 8601773Abstract: An in-line insert folder system includes a continuous roll of preprinted inserts, and a cutter for cutting individual inserts from the roll. A transport serially conveys the individual inserts in a downstream direction to a buckle folder that receives the inserts and folds each one along at least one fold line. An applicator serially receives the folded inserts from the buckle folder and applies the inserts to consumer packs such as cigarette packs, for example. The folded inserts may be directly applied to the packs before placement of flexible outer wrap or the folded inserts may be applied onto the flexible outer wrap before that wrap is placed around the packs.Type: GrantFiled: May 28, 2003Date of Patent: December 10, 2013Assignee: Philip Morris USA Inc.Inventors: Edmond J.
