Title: METHOD AND MACHINE FOR PRODUCING A SPACER
Abstract:
The present invention relates to a machine for manufacturing spacers for concrete reinforcements and concrete structures, methods for manufacturing such spacers, and the use thereof. The spacers (400) comprise three parallel straight longitudinal wires which form the sides of a triangular prism, wherein each of the bottom longitudinal wires (401) is connected to the top longitudinal wire (401) by means of a frame structure (402). The machine (100) comprises a welding installation (200) for welding together the two frame structures to the top longitudinal wire and optionally welding together each of the frame structures to a bottom longitudinal wire, and a drive mechanism (300) for transporting the spacers through the welding installation wherein the drive mechanism is positioned downstream of the welding installation.
