APPARATUS AND METHOD FOR PRODUCING SACKS WHICH COMPRISE WOVEN FABRICS MADE FROM STRETCHED SMALL PLASTIC TAPES

摘要

The invention describes an apparatus for producing sacks from tubular parts which comprise woven fabrics made from stretched small plastic tapes and are composed of two material layers which lie above one another. The following are contained in said apparatus: - at least one transport device for transporting the tubular parts in a transport direction (x) which extends transversely with respect to their direction (z) of extent, wherein the tubular parts can be conveyed in a horizontal position, and - at least one device for opening at least one end of a tubular part, in order to form bases later. The device for opening at least one end of a tubular part comprises the means for folding over the ends of the tubular parts, by way of which means the two ends of the tubular parts can be moved out of the horizontal position into a vertical position (y), wherein, furthermore, the material layers lie on one another.
