摘要： The disclosure relates to the production by means of an electrical resistance welding method, of grids formed from metal wires crossing over another. The grid wires are carried through between rows of cooperating electrodes and, under pressure, are welded together at the cross points of the wires by an electric current. Each cross point of the wires and the surfaces of the associated electrodes of the grid welding machine, which lie in the welding region, are subjected to the action of a liquid coolant to increase the life of the electrodes and reduce distortion of the grid due to the localized heating of the wires.

摘要： Wires are picked from a loose bundle of wires which have been cut to length, prior to feeding to a processing machine such as a grid welding machine. The bundle is laid on a supporting table (23) so that end parts of the wires project freely beyond the table. A lifting beam (18) having a vertical slot (19) is then raised beneath the projecting end parts of the wires so that most of the wires are raised but the others are received one above the other in the slot. A gripper having clamping cheeks (20) is applied from below and grips the lowermost wire in the slot. The gripper is mounted on a carrier (2) which is movable parallel to the wire axes to pull the gripped wire longitudinally out of the slot.

摘要： A bending mechanism for wire or strip material is provided, which is intended in particular for bending back towards the edge longitudinal wires the projecting end portions of crosswires of reinforcement grids for reinforced concrete construction. The mechanism comprises a substantially circular-sectioned cylindrical bending form, and a bending-tool eccentrically mounted on a rotatable tool carrier which can be rotated in either direction about the axis of the bending-form. The bending-form is shiftable along said axis between a working position, in which the end faces of said tool carrier and said bending-form are substantially touching, and a rest position in which said two end faces define between them a gap for the passage of a wire which is to be bent, in particular a crosswire of a reinforcement grid.

摘要： A lattice girder making machine has a stepwise feed mechanism for upper and lower chord wires; and a continuously operating bending mechanism for bending wire into zigzag strutting which is welded to the chord wires at a welding station. Between the bending mechanism ad the welding station the zigzag strutting slides along guides which allow the strutting alternately to contract resiliently and then to expand to accommodate the stepwise advance through the welding station. At the welding station the strutting is held at the required extension by fingers.

The feeder arms are fitted with clamping devices (11,12) for the transverse wires and can be moved together back and forth between the insertion lines and the welding lines along predetermined tracks (U, U'; O, O'). At least one of the feeder arms can be moved by means of a mechanical drive (22) in order to prestress both transverse wires relative to the other feeder arm in the direction of the transverse wires, and the transverse wires are positioned precisely in accordance with the predetermined distribution of the transverse wires by means of pivotable positioning elements (17,17' ) provided in the region of the welding lines.
