摘要 A cylindrical body of a fiber drum comprises a roll of a paper material having two opening ends; and a curled portion formed by inwardly curling the edge of at least one of said two opening ends. A method of fabricating said fiber drum comprises the steps of winding a length of paper sheet in layers, between which an adhesive is applied, to form a roll of the paper sheet having two opening ends, and inwardly curling the edge of at least one of said two opening ends of the roll to form a curled portion before the adhesive is cured between the layers.
