11897023 · 2024-02-13 · ·

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.

Method for manufacturing three-dimensional lattice truss structure using flexible linear bodies

A method for manufacturing a three-dimensional lattice truss structure using flexible wires, including: arranging a plurality of out-of-plane wires; forming crossing portions between the plurality of out-of-plane wires; inserting a plurality of in-plane wires in the crossing portions; translating the plurality of in-plane wires in the z-direction; and inserting boundary rods in the y- or x-direction inside the plurality of out-of-plane wire groups.

Multiple wire wrap screen fabrication method

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.
