Provided are a method and device for forming a cylindrical member in which belt-like members can be accurately formed into a cylindrical shape without meandering. A pre-winding position sensor (4) detects a position of a member reference line (L1) extending in a longitudinal direction of a belt-like member (8a) along the entire length of the belt-like member (8a) in the longitudinal direction thereof before the belt-like member (8a) is placed on a transport conveyor belt (3), transported to a forming drum (2), and wound around the forming drum (2). The belt-like member (8a) is wound around the forming drum (2) and formed in a cylindrical shape while the forming drum (2) is relatively moved in the drum width direction with respect to the transport conveyor belt (3) by a controller (6) and the member reference line (L1), referred to when winding the belt-like member (8a) around the forming drum (2), and a drum reference line (DL) are matched, on the basis of the detection data and a position data of the drum reference line (DL) orthogonal to the drum axial center (DX) of the forming drum (2) and set in a predetermined position of the drum width direction. |
