APPARATUS AND METHOD FOR PRODUCING BAGS FROM TUBULAR PIECES, WHICH PREFERABLY COMPRISE WOVEN FABRICS MADE OF SMALL STRETCHED PLASTIC TAPES AND ARE COMPOSED OF TWO WALLS LYING ONE ON TOP OF THE OTHER

摘要

The invention relates to an apparatus (1) for producing bags from tubular pieces (13), which preferably comprise woven fabrics made of small stretched plastic tapes and are composed of two walls lying one on top of the other. Said apparatus comprises at least one transport device by means of which the tubular pieces (13) can be transported to the individual processing stations (8, 9, 10, 11) in a transport direction (x) that extends transversely to the extension direction (z) of the tubular pieces (13), at least one bottom opening station (8) by means of which open end sections can be produced at at least one end of a tubular piece (15, 15') by folding areas of at least one wall of the tubular piece about folded edges (36), and at least one closing station (10, 10') by means of which the open bottom squares can be laid and closed into bottoms by folding parts of the walls and/or tabs about further folded edges (36), and at least one embossing device by means of which at least one part of the later folded edges (36) can be embossed into the tubular pieces (13).
