Abstract (en)
[origin: EP0826834A2] The cover has an insert (4) with a top flange for a lid (1), and a ring-shaped part (6), fastened to elements (5) on the lid. The flange has the same shape as the top shaft end. The tubular insert projects into the shaft (2). For height-adjustment, the cover part is fastened to the elements on the lid at the correct height, and is then placed on the top shaft end. The elements on the lid are formed by mainly horizontal ribs, and correspondingly shaped grooves (7) on the ring-shaped part engage over the ribs.
