Automated Cap Presentation specification should start with the real closure.
Cap presentation is the final and often most critical part of the feeding route. Even a good feeder will cause stoppages if the cap arrives at the capping head at the wrong angle, with too much chute pressure or with inconsistent spacing.
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.
