ABSTRACT:
Lightweight containers such as polyethylene terephthalate (PET) beverage bottles are rendered stable for conveyance on a horizontal conveyor by addition of water ballast. Ballast in the amount of about 3 to 10% of the bottle volume is sufficient to enable increased production line speed with fewer bottle jams due to the lightweight bottles falling over. The bottles are arranged upright, for example at the outlet of a depalletizer, and loaded with ballast from a reservoir or pressurized supply of water. Preferably, the bottles are loaded in a group and a plurality of valves having valve bodies on a movable common support open simultaneously. The ballast is removed at the bottle rinsing station, which inverts the bottles to drain the ballast as well as rinse water.
