A bar conveyor belt includes two parallel longitudinal chains and a plurality of bars forming the conveying surface and fixed at their ends to the successive links of the two chains. Each chain link consists of a metal plate bent in the form of a U with its arms disposed to define a space intended to partially house that adjacent link positioned upstream with reference to the chain advancement direction, the arms being provided with a longitudinal slot for passage of that bar connected to the downstream link, the outer arm presenting an appendix engageable by the teeth of a drive sprocket. The appendix of each link is bent in the chain advancement direction to form a tooth with a complete involute profile, and the end of each bar extends into the appendix and is fixed to the top thereof, after passing through two holes provided in the arms of the link and the slots provided in the arms of the upstream link.
