    (54) Can closures


    (57) A method of closing a can includes the following stages;
    locating a closure member (l4) within a cylindrical wall portion (l2) of the can (ll) with a resilient sealing element (l7,23ʹ) disposed between the periphery (l9) of the closure member (l4) and the cylindrical wall (l2), so that the closure member (l4) is slidable axially of the cylindrical wall portion (l2);
    adjusting the position of the closure member (l4) axially of the cylindrical wall portion (l2) to give the required internal axial dimension;
    and rolling a groove (l5) in the cylindrical wall (l2) of the can (ll) to abut one side of the closure member (l4) while simultaneously rolling the end of the can (ll) over to abut the other side of the closure member (l4), the sealing element (l7,23ʹ) being compressed during the rolling process. This method may be used to produce the casing (l0) for a servo actuator.
