Abstract: An end cover for covering and protecting a drum having an upper tray with a circumferential lip. The end cover includes a circular top provided with an outer circumferential edge. The diameter of the top corresponds to the diameter of the drum to be covered and has an axis of symmetry perpendicular to the plane of the top. The end cover also includes a peripheral member comprising a convergent linear wall integral with the outer edge of the top, a divergent linear wall joined to the convergent linear wall and forming a circumferential V-shaped groove opening toward the exterior of the walls, and flat ribs spaced from one another around the V-shaped groove, each of the ribs being disposed in a vertical radial plane passing through the axis of symmetry, protruding from and being integral with the walls on either side of the apex of the V-shaped groove formed by the walls, and being positioned within the V-shaped groove to add rigidity to the walls and for preventing the walls from spreading apart.
