Abstract
Abstract A wear strip for conveyor chains comprising a flat upper wear member having at least two spaced-apart holes therethrough for the reception of connection means, at least one linear support member joined to the underside of the wear member, and at least two base members joined to the underside of the wear member and having holes therethrough in registry with the holes through the wear member. The whole wear strip is preferably integrally injection molded, and each of the holes in the wear member are preferably countersunk on the upper surface. Two embodiments are disclosed, one in which one linear support member is joined to the wear member along each lateral edge thereof and one in which a single linear support member is joined to the wear member along one lateral edge thereof.
