An apparatus for producing bags from tubular material having fabric made of stretched plastic strips has at least one tube-forming device or a tube-unwinding device, by which tubular material for producing bags can be produced from web-shaped material and in which the tubular material, can be conveyed in a transport direction (x′), at least one tube-separating device, by which tube pieces can be separated from the tubular material, a bottom-forming device, by which bottoms can be molded onto at least one end of a tube piece, and at least one transport device for transporting the tube pieces within the bottom-forming device in a transport direction (x) extending transversely to their direction of extension (y) The transport direction (x′) of the tubular material in the tube-forming device or the tube-unwinding device and the transport direction (x) of the tube pieces in the transport device are parallel to each other.
