| 1. An apparatus for producing bag packages (10), from a length of packaging material, the apparatus comprising
a folding station (52) for forming folds (44) in a moving sheet of packaging material,
a sealing station (54) downstream of the folding station for sealing the formed folds (44),
a packaging material driving station (58) downstream of the sealing station, and
a forming station (56) for forming a sheathing tube from the packaging material, whereby before the sheathing tube is formed, the forming of the
sealing seams (12, 76) onto the packaging material sheeting (26, 42, 60) is done,
said folding station (52) comprising at least two folding plates (40; 68A, 68B) disposed side by side in the travel direction of the length of packaging material in such a manner that at least two adjacent
side edges, disposed side by side, of the folding plates (40; 68A; 68B) are oriented parallel to the travel direction of the length of packaging material; wherein the packaging material is guided
along the underside of a first of said folding plates (40; 68A) and along the top of a second of said folding plates (40; 68B) by said at least two adjacent side edges, further comprising a feed roller (70) between the folding station (52) and the sealing station (54).
