Caps and Closures Feeding specification should start with the real closure.
The phrase caps and closures covers threaded caps, snap-on caps, flip-tops, pumps, triggers, spouts and overcaps. Each closure has a different centre of gravity and a different risk of jamming. The feeding method should be chosen after reviewing real samples and line requirements.
For a better buying decision, the useful comparison is not only hopper size or headline speed. It is how the feeder behaves with your closure, how the capper receives the cap and how easy the line is to run after changeover.
The safest specification route is to start with real closures, target output, line photos and the exact point where the cap must be presented. That avoids choosing a feeder on a generic speed figure that does not match the cap or capper.
