This paper will cover the design of the horizontal rivet injector use on the SA2 LVER designated for stage 0 production of Airbus A320 Upper Wing Panels. The injector design is intended to decrease cycle times and increase reliability while not reducing the functionality over previous rivet feed designs used by Electroimpact. Specific rivet handling methods and design features will be reviewed and their result on cycle time and reliability discussed.

A new method of installing LGP collars onto titanium lock bolts has been brought into production in the Airbus wing manufacturing facility in Broughton, Wales. The feed system involves transporting the collar down a rectangular cross-sectioned hose, through a rectangular pathway in the machine clamp anvil to the swage die without the use of fingers or grippers. This method allows the reliable feeding the collars without needing to adjust the position of feed fingers or grippers relative to the tool centerline. Also, more than one fastener diameter can be fed through one anvil geometry, requiring only a die change to switch between certain fastener diameters. In our application, offset and straight stringer geometries are accommodated by the same anvil.
