Abstract
A flat belt drive is trained around spaced apart drive and idler rollers. The belt has an outer load bearing surface and an inner surface wetted to reduce friction on the inner surface where the load is applied. Drainage channels or grooves in the exterior surface of the drive and idler rollers function to remove liquid from between the rollers and the inner surface of the belt in order to maintain a high frictional coefficient therebetween. Alternatively, drainage openings are provided in the roller to convey the liquid away from the roller surface to the hollow interior thereof.
