Inline cappers rely on a stable cap queue.
Inline capping machines often need a steady queue of caps presented to the bottle path. If the cap feed starves, floods or loses orientation, the line can suffer from missed caps and inconsistent application.
The feeder route may include a hopper, elevator, bowl feeder, cap sorter and chute. The chute angle and queue pressure are especially important for inline spindle and belt capping applications.
The correct design depends on cap shape, capping speed, bottle stability and the layout around the conveyor.
