Abstract
In a slat conveyor, slats for supporting conveyed articles and personnel extend between two side-by-side, spaced, endless roller chains engaged with driving sprockets at one end of the conveying path and driven sprockets at the other end. At a location radially outward from the pitch circle, the distance between the front surface of the sprocket teeth to the tooth center line is at least as great as the distance from the centerline to the front surface at the pitch circle. The tooth faces merge smoothly with the tooth gap bottom, and the root diameter is smaller than the root diameter according to ISO standards.
