A drum of disposable type to carry a coil of cable or line, for instance, comprising a sleeve and two circular end pieces, each of which is attached to the sleeve by an attachment mechanism at its end portions. Each end piece is provided with a concentric, cylindrical engagement and support flange on the side facing towards the sleeve, the flange having an axial length of 20-50 mm, depending on the diameter of the drum, and being arranged to be received with friction-fit into the interior of the sleeve so that the outside of the flange presses against the inside of the sleeve, the attachment mechanism being arranged within the area of the flange and adjacent end portion of the sleeve so that, in cooperation with the friction engagement of the flange itself, a stable, permanent joint is achieved. |
