摘要

Waste water rake (10) comprises a lattice consisting of gaps (20) separated by bars (16) and having gripping elements (22) passing through the gaps on the waste water inlet side and joined to a circulating pulling organ (24) such as a chain. The lattice is a cage formed by the bars. The gripping elements revolve between the gaps and are recessed so that their free ends (44) run directly within the gaps. Preferred Features: The bars are revolving plastic bars following the course of an oval. The bar is an injection-molded part made in one piece.
