Abstract
A multiple-belt conveying apparatus includes at least one endless inner belt movably wound on at least one substrate plate secured to a base having two arcuate end portions disposed on a front end portion and a rear end portion of the substrate plate for movably winding the endless inner belt on the two arcuate end portions of the substrate plate, having an inner slipping surface and an outer frictional surface; and an endless outer belt movably wound on a front roller and a rear roller fixed on a base, the outer belt movably overlapping the inner belt (or belts) with an inner surface of the outer belt frictionally contacting the outer frictional surface of the inner belt, and the inner belt having its inner slipping surface slidably contacting an upper slipping surface formed on an upper surface of the substrate plate, thereby providing a belt conveying apparatus having a flat top surface for comfortable and minimum stress loading, riding or walking on the outer belt and also for a smooth movement of the belts.
