  • the rails 4.1 to 4.6 are on the function as longitudinal guide members for the wire guide means (the pliers e.g. 13.3) matched and mostly have insufficient stability on.
  • the rails 4.1 to 4.6 are chosen as small as possible so that they are a have sufficient elasticity for continuous adjustment and usability guaranteed the device according to the invention over a longer period of time is. On the other hand, they are chosen as small as possible so that the longitudinal wires are not primarily are guided in the rails 4.1 to 4.6 and thus unnecessary deformations are exposed.
  • Each rail 4.1 to 4.6 is therefore used to improve the stability stable longitudinal member 26 assigned.
  • a rectangular beam is used as the longitudinal beam 26 Rolled profile, used as an RHS profile.
  • the longitudinal beam 26 is like the associated one Rail z. B.
  • the metal strips 27.1 to 27.4 are spaced from each other in such a way that the rails 4.1 to 4.6 transversely can adapt to the continuous change in distance without this adjustment is hindered by the metal strips 27.1 to 27.4 when the spacers 28.1 to 28.3 laterally between the spaced sheet metal strips 27.1 to 27.4 and move around.
  • the metal strips 27.1 to 27.4 for example fixed to the rail construction of the longitudinally movable cross members 10 and 11 become.
  • these preferably at several points along the transverse direction of the device for Ground supported.
  • the control of the two cross members 10 and 11 can be modified so that that the cross member 11 moves toward the cross member 10 when the latter has the line wire transported from the dispenser to the welding unit to follow the path of the first Shorten cross member 10.
  • more than two cross beams can be placed in one and the same linear line wire feeder can be arranged.
  • the pliers grip on the first cross member the line wire at the dispenser and passes it to the pliers of the next cross member. This transports the line wire on and passes this to the tongs of another cross member for transport or to the Pliers of the crossmember, from which the longitudinal wire of the associated welding unit is fed.
  • the device according to the invention could also only be used one crossmember and therefore only one pair of pliers per rail.
  • the production quantity on structural steel mats at the same time would be much smaller than it with the arrangement of two or more cross beams.
  • the pliers can be used on a carriage construction slide along the rails.
