<p>A machine cover comprising a main body (1) having two or more apertures (6) closed by interchangeable closures (8, 9), at least one of which incorporates an inlet duct (12) so that this inlet duct can be located in one of two or more different positions in the cover. A pair of interchangeable closures for an adjacent pair of apertures may be formed in a single component (8) that is reversible end-to-end and which cooperates with both apertures (6) so that the filler duct (11) is aligned with either one whilst the other aperture is closed. One or more closures are provided to close each of the other apertures, one closure (9) being provided for each pair of adjacent apertures if desired. Alternatively, the closure (8) incorporating the filler duct (11) may be engageable with each aperture (16) in each of two or more different orientations in each of which the filler duct is located in a different position. </p> |
