Minimum pressure conveyors are typically comprised of a belt-driven roller conveyor with some type of adjustment to allow the drive of rollers to be increased or reduced. Belt-driven roller conveyors with knurled thumb spring adjustability lower and raises the belt driving against the rollers carrying the product. This ensures that when the product is driven together at the end of the line, the pressure of the upstream boxes does not crush the first carton to reach the end.
