The Auto-Kick 5000
The Auto-Kick 5000 is a custom mechanism built for a bicycle rim rolling machine. It keeps the lead end of the rolled extrusion from re-entering the rollers upon completing the first 360°, then gets out of the way to keep from putting scratches in the rims.
It is automated with a pneumatic cylinder and solenoid valve, a couple photo eye sensors and a latching relay - simple, affordable, reliable.
