The invention enables a built band (B) in a cylindrical shape to be easily and surely detached by peeling off the band (B) from being brought into close contact with a drum peripheral face in an expandable and contractable band building drum (D) constituted by two kinds of pluralities of segments (1a) (1b) arranged alternately in a peripheral direction, a diameter of one segment (1a) of two kinds of segments (1a) (1b) is contracted, thereafter, the segment (1a) is temporarily returned to a diameter expanding state, a diameter of other segment (1b) is contracted, thereby, the band (B) is peeled off from being brought into close contact with the drum outer peripheral face, thereafter, the band (B) is detached by bringing both of the segments (1a) (1b) into a diameter contracting state. |
