Machine and method for producing a packet

摘要

A method and machine (1) for producing a packet (2), whereby, as it is fed along a feed path (P), a substantially flat blank (9) with preformed fold lines (13) is extracted from the feed (P) for transfer, crosswise to the feed path (P), to a stretch-folding station (21) for stretching at least some of the fold lines (13), and is then fed back onto the feed path (P) and allowed to spring back to its original flat shape.
