1. A scraper bar for use in a plant for producing a paper web with a sieve belt, the scraper bar comprising:
a scraper body having a longitudinal extent and the sieve belt is movable over said scraper body transversely with respect to the longitudinal extent, said scraper body having a supporting bar and wearing elements disposed above said supporting bar, said wearing elements facing toward the sieve belt and disposed one after another in a direction of the longitudinal extent of said scraper body, said supporting bar 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.
