A lining drum which has a tubular body having open ends, an inlet for compressed air and an outlet for liner is disclosed. The lining drum has end pieces removably attached to the tubular body for closing the open ends of the tubular body, a rotatable shaft inside the tubular body and a crank for rotating the shaft. An elastic fastener has a first end in operative engagement with the tubular body and a second end in operative engagement with the end piece. The second end is opposite the first end. The end piece is movable between a closed position and an open position by extending the elastic fastener against an elastic biasing force of the elastic fastener. The end piece and the tubular body has a gap defined therebetween when the end piece is in the open position.
