ABSTRACT:
Article wrapping apparatus, particularly for wrapping cigarette packets in wrapper film, includes separate cutters (34A,14) respectively for severing a wrapper web into separate sections and for cutting the leading end of a tear strip attached to each section. Drive means (24) is provided for varying the path length of the web between the cutters. Separate drives (12,30) are provided respectively for the cutters and for the web, these being synchronized with a further separate drive for the articles. An air mover (32) assists feeding of the web towards the main cutter (34A); a further air mover (50) assists feeding of wrapper sections across and beyond the path of an article to be wrapped. Opposed belt conveyors (43,44) may be clamped together under action of air cylinders for feeding of wrapper sections without loss of timing.
