Method of producing a packaging pouch, of the type consisting in forming a tube (21) on a rotary machine by longitudinally rolling at least one band (2) of flexible material which is paid out, and then dividing said tube (21) into lengths (22) and forming the bottom (10) of each pouch (1) to form a compartment. It consists in: paying out and driving and feeding into the forming tube (21) at least one other band (3), of another material or the same material; simultaneously dividing the tube (21) into lengths (22) and the other band (3) into segments (31); causing the front part of the tube (21) to become staggered relative to the front part of the other band (3), or the lengths (22) to become staggered relative to the segments (31); and finally forming the bottom (10) of each pouch by folding each length (22) transversely. |
