Claim 15:
16. A plant for producing a paper web, the plant comprising:
a sieve belt;
scraper bars, wherein said sieve belt is movable transversely over said scraper bars, said scraper bars have supporting bars and wearing elements disposed above said supporting bars, said wearing elements face toward said sieve belt and are disposed one after another in a direction of a longitudinal extent of said scraper bars, each of said supporting bars having supporting bar elements disposed one after another in the direction of the longitudinal extent and are connected to one another, and said wearing elements are fastened on said support bar elements; and
said supporting bar elements having end faces at which they bear against adjacent ones of said supporting bar elements, said supporting bar elements each having at, at least one end face of said end faces, a form-fit geometry which engages into said form-fit geometry of an adjoining one of said supporting bar elements, said form-fit geometry having ribs or projections being oriented horizontally, and parallel to said wearing elements, such that joined together said supporting bar elements engage in one another in a tooth-shaped manner by way of said form-fit geometry of each of said supporting bar elements, wherein said form-fit geometry ensures that top sides of adjoining ones of said wearing elements supported by said supporting bar elements are exactly aligned with each other in their respective heights.
