  • Patent number: 5068960
    Abstract: A device for the insertion of filling wires into a wire jointed-band is described, being positioned in the conveying direction of a machine for the production of the wire jointed-band behind a feeding device for the plugging wires. By means of a guiding plate with channels and a roller the filling wires are inserted into the respective openings of the already completed wire jointed-band. The device according to the invention allows a sectional mechanical insertion of the filling wires into the actual wire jointed-band. The filling wires can be inserted simultaneously with the plugging wires, resulting in a substantially higher production speed.

  • Patent number: 4920638
    Abstract: There is described a method and a device for the production of a wire jointed-band of alternately clockwise and counterclockwise, respectively, wound spirals of metal wire or artificial resin wire, wherein the spirals are guided to a narrow pass such that the windings providing the spirals open themselves in the area of the narrow pass and in this the parallel spirals partly are pushed into each other such that in each case one of the windings of one spiral is placed between adjacent windings of the adjacent spiral whereby the spirals thus fitted into each other are connected with each other by inserting a coupling wire into the space provided by the overlapping windings and whereby in each case several of the pairs of spirals fitted into each other are guided to the narrow space in which area the spirals are driven in the transporting direction. This is resulting in a high production speed and broad wire jointed-bands.
