Orientation is the difference between feeding caps and feeding usable caps.
A cap can arrive at a capping machine quickly and still be wrong. Orientation systems ensure the cap is open-side, thread-side or feature-side in the correct position before handover.
The method can include bowl tooling, sorter discs, reject tracks, sensors, air assistance or mechanical guides. The best option depends on the closure shape and how obvious the correct orientation is mechanically.
Cap orientation should be specified with the capper interface because the required exit orientation may change from one machine type to another.
