<p>A method of forming a cylindrical member includes the steps of: attaching an auxiliary bar (32) having a shape of a substantially triangular prism to a forming drum (25); supplying a belt-shaped member (B) cut to a predetermined length toward the forming drum (25) and causing a leading end (B1) of the belt-shaped member to be attached to one (34) of side surfaces of the auxiliary bar; supplying the belt-shaped member (B) onto the forming drum (25) while the forming drum is being rotated so as to wind the belt-shaped member (B) around the forming drum, and attaching a trailing end (B2) of the belt-shaped member to another side surface (35) of the auxiliary bar; separating the leading end (B1) and the trailing end (B2) of the belt-shaped member from the auxiliary bar (32); removing the auxiliary bar (32) off the forming drum (25); and causing the leading (B1) and the trailing end (B2) of the belt-shaped member to butt against each other on the forming drum. Also provided is an apparatus for forming a cylindrical member. <IMAGE></p> |
