Multi-Conveyor recently built a set of sanitary food-grade conveyors that combine dual lanes of cup-size containers to feed an existing metal detector.
The first conveyor section starts at an existing filler discharge that transfers dual lane product on 6-1/2" centers. The 2-lanes travel through a 90 degree curve on side flexing chain, set at precise speeds to facilitate a natural 2-to-1 combiner using a simple angled side rail.
