This relates to a fibre drum construction and more particularly to the reinforcement of the chime which is utilized to shape an end part of a fibre drum body to receive and tightly clamp in sealed relation the periphery of the drum wall. The end part of a conventional chime includes a plurality of flanges arranged to define a radially inwardly directed channel with the lowermost flange terminating in a curl. The endmost flange, which is annular, is provided with radiating ribs which project axially inwardly into the overlying portion of the drum body and serve to rigidify the channel. The ribs extend vertically into a vertical flange of the flanges and terminate generally within the curl, with the ribs extending entirely across the end flange.
