Abstract: A control plate (1) of a hydraulic machine having a core (2) is disclosed, which at least on its upper side (O) lying in operation against a cylinder drum is covered with a layer of a friction-reducing plastics material (3) and which has at least two control openings. In a control plate of that kind, it is desirable to simplify manufacture, during which subsequent machining is effected after the plastics material has been moulded on. For that purpose, the plastics material (3) is joined to the core (2) by means of at least one connecting element (8) which, as a result of interlocking engagement with the plastics material (3) and/or the core (2), takes up tensile forces substantially at right angles to the upper side (O).
