Method and machine for producing longitudinally and transversally sealed foil bags from a non-form stable foil sheet

A method for producing longitudinally and transversally sealed filled foil bags, comprising the steps of:

• a) positioning at least one non-form stable, individual, finite foil sheet on one of a plurality of transport slides of a transport device, wherein the transport slide is movable independently from any other transport slide in a transport direction,
• b) retaining the at least one foil sheet on the transport slide by sucking the foil sheet against the transport slide,
• c) transporting the at least one foil sheet by the transport slide in the transport direction sequentially to processing stations where the following processing steps are being performed:
• d) placing at least one product on the at least one foil sheet on the transport slide,
• e) fabricating a first sealing seam by placing two edge portions, that extend in the transport direction of the at least one foil sheet against each other and sealing them in a first sealing step thereby forming a foil hose, and
• f) fabricating two second sealing seams oriented transversally to the first sealing seam in a second sealing step in that two opposite portions of ends of the foil hose are placed against each other and sealed, over an entire width of the foil hose, at both ends at the same time,
• g) fabricating at least one filled and circumferentially sealed foil bag, wherein the at least one sealed foil bag is formed from an entire foil sheet of the at least one foil sheet and no leftover or cut off scrap remains.
