  • The position of the bolt must be oriented correctly when inserting it into the work-piece. Our chucking method, with the chuck opened by pushing down the bolt, is superior to any other method.
  • The lower electrode assembly is an integral part of the Dengesha Bolt Feeder and ensures a perfect alignment of the panel and the bolt every time.
  • If a bolt fails to feed, the feeder will give a fault condition, providing safety and security in automated applications.
  • Beeing specially designed for projection welding and forming a integral part of the process, makes these feeders highly reliable for use in automated production.
  • High speed feeding.
  • Bulk hopper is available for automated production lines and can be fitted with a level switch to indicate re-filling is required.
  • Special designs are available, including direct connection of guide pin to the air cylinder in lower electrode, together with extend and retract position proximity switches and additional solenoid, which allow positive control of the guide pin location in the work piece.

Lerocon AB is a privately owned company, based in Gislaved since its inception in 2003. Initially our focus was on service and support of special machines and resistance welding machines. Fairly soon we saw the need for a custom automation nut welding machine and began to produce the first models for the Lerocon Multi Weld.
