ABSTRACT:
A conveyor propelling member is disclosed. The propelling member consists of a chain to provide a primary tension load member and a plurality of strips of a flexible material, such as plastic, having a relatively high coefficient of friction. The strips are of a length equal to a number of chain links and, at spacings equal to two chain links, have lugs which seat through openings in the chain leaving the remaining chain link openings free for engagement by a sprocket. These strips are arranged in tandem along the entire length of the chain. The lugs at the ends of each strip are stiffened by rivets.
