A device for producing a metal mesh reinforcement that includes joining a plurality of long profiles and a winding profile. The device includes a welding unit for welding a longitudinal profile to a winding profile and a feed unit for feeding a portion of the winding profile provided from a master to the welding unit. The feed unit includes a cutting arrangement for cutting a profile portion of the winding profile from the master. The cutting arrangement is arranged within a cutting zone of the device remote from the welding unit such that, after cutting of the winding profile, the end portion of the winding profile cut from the master is fed from the cutting zone to the welding unit and at least one further weld is made between the cut-off end portion of the winding profile and a longitudinal profile to produce the metal mesh reinforcement.

A wire wrap screen manufacturing method for a given screen diameter involves simultaneous winding of parallel wires that begin in circumferentially offset locations on one end of a perforated base pipe that has circumferentially spaced support rods saves fabrication time. Each of the ends of the wires lie in a common plane to allow fitting an end cap for sealing or to just continuously weld at the ends of the wires to seal the assembly to the base pipe. The spot welds to the support rods occur as the wire is wound over such rods. Equal initial circumferential spacing of the start locations for the wires is preferred although asymmetrical spacing is preferred.

An apparatus for equipping a basket welding machine, the apparatus having an insertion device. The apparatus is characterized in that the insertion device has a plurality of receiving positions for all the longitudinal wires of a basket to be produced using the basket welding machine, the insertion device having a receiving element for receiving the longitudinal wires of a basket, the receiving positions being spaced apart in the radial direction from an axis of rotation of the insertion device, wherein the insertion device is designed to feed at least two longitudinal wires arranged on the insertion device to the basket welding machine simultaneously in one insertion operation, the insertion operation of the longitudinal wires into the basket welding machine being effected by a movement of the insertion device in the axial direction of the axis of rotation of the insertion device. The invention further relates to a basket welding machine.

Device for producing reinforcements, in particular reinforcement baskets for concrete pipes having a bell-shaped socket end, having an expansion device which has a single expansion slide, wherein the expansion slide is configured for modifying, in particular, during the production process of the reinforcement, a radial position of an assigned actuating element for a longitudinal wire of the reinforcement by way of a transmission mechanism of the expansion device. The device is characterized in that the expansion device has a mold slide, wherein an actuator drive is provided for moving the mold slide, and wherein the actuator drive for a linear movement of the mold slide in relation to the expansion slide is supported on the expansion slide.

A method and apparatus for rebar cage construction is disclosed. A computerized controller operates an apparatus that automates parts of the rebar cage formation process. The computer controls motors for rotating the barrel and operating a wagon containing spiral coil wire. Initial rods are placed on a plurality of latitudinal conveyors. Dual cage ring assemblies are placed on the latitudinal conveyors, and notches or slots within the cage rings engage with the initial rods. The conveyors rotate the dual cage ring assemblies and a rod dispenser places a rod in additional notches. The rods, when completely installed, form a barrel structure. A wagon containing spiral coil wire is then moved longitudinally while the conveyors rotate to wrap the spiral coil wire around the barrel, to form a spiraled rebar cage.
