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