Abstract
A conveyor chain formed of parallel links with pins extending laterally therefrom has pads mounted to the pins. Each pad has an elongated planar upper surface extending further than the distance between adjacent pins on the links. A notch on each end of the pad enables adjacent pads to overlap each other, and the shape of a notch and location of apertures in the pad enables the upper surfaces to define a substantially continuous contact surface when adjacent chain links are not wrapped, and enable the chain to engage a drive sprocket regardless of the direction of wrap.
