Patent ID: 7493924

Claim:
An apparatus for processing chain link fabric, the apparatus comprising a welding assembly configured to weld together wire-end portions of the chain link fabric, the welding assembly including a guiding assembly having a finger and a cam that are configured to restrict the movement of the wire-end portions while the welding assembly welds the wire-end portions together, wherein the finger and the cam are configured to move relative to the wire-end portions both before and after the wire-end portions are welded together, wherein: the cam is configured to rotate toward the wire-end portion as the finger moves toward the wire-end portions; and the cam is configured to rotate away from the wire-end portions as the finger moves away from the wire-end portions; and wherein the guiding assembly includes a guiding assembly air cylinder, the guiding assembly includes a guiding assembly air cylinder shaft that interfaces with the guiding assembly air cylinder; and a finger block coupled between the guiding assembly air cylinder shaft and the finger; wherein the guiding assembly air cylinder in combination with the guiding assembly air shaft is configured to move the finger block and the finger relative to the wire-end portion; and wherein the finger block contacts the cam as the finger moves toward the wire-end portions causing the cam to rotate toward the wire-end portions; and the cam rotates away from the wire-end portions as the finger moves away from the wire-end portions.
