The caps are sorted by the rotary cap sorter, when in the correct orientation caps exit the feeder and enter into the cap delivery channel. Each cap is released from the channel onto a rotating "transfer disc".
This disc puts the cap in the correctly timed sequence or "pitch" so that the cap is positioned directly under its' capping head. The capping head descends down onto the cap and seizes it in the capping jaws, the capping head then places the cap onto the bottle neck and tightening begins.
If there is no container or bottle to be capped, then no cap is released from the cap delivery channel (cap dispensing is timed to the bottles presence) NO BOTTLE - NO CAP,
Depending on the type of cap, a variable speed unit can be fitted onto the closing turret to enable increased rotation of capping heads.
