Abstract
A method for removing a cylindrical member from a radially expansible and contractible band-forming drum and transferring the cylindrical member to a subsequent station. The cylindrical member includes a cylindrical laminate structure prepared by winding tire constituent elements in the form of an inner liner and a carcass ply around the band forming drum, and a pair of bead rings axially spaced from each other and fixed and held at predetermined positions on the outer circumference of the laminate structure. The bead rings are grasped while maintaining a predetermined distance therebetween, without displacing the bead rings before the band-forming drum is contracted to decrease its diameter. At least the axial end of the cylindrical member close to the subsequent station is held in a slightly radially expanded state, and the band-forming drum is then contracted to decrease its diameter to allow removal of the cylindrical member from the drum in its axial direction.
