Abstract
Slats of a slat conveyor chain each have a multiplicity of drain holes distributed in a desired pattern, and discharge grooves formed in the underside of each slat along sliding surface portions facing guide rails of the slat conveyor chain. A treatment liquid, such as lubricating liquid or washing liquid, supplied onto a load-bearing upper surface of the slat conveyor chain for stable and damage-free conveyance of articles such as PET bottles, cans and so on is smoothly discharged from the discharge grooves through the drain holes without scatting around a frame of the slat conveyor chain. With this discharging of the treatment liquid, bearings and a speed reducer of a chain drive mechanism are protected against corrosion. The slat conveyor chain can, therefore, operate reliably over a long period of use while keeping the surrounding environment against contamination with the treatment liquid.
