Document Type and Number:

WIPO Patent Application WO/2014/196246

Kind Code:

A1

Abstract:

In the present invention, the space needed for forming a cylindrical carcass band is reduced, and carcass band forming productivity is improved. A first forming drum (21) forms a cylindrical carcass ply (3). A second forming drum (22) forms a cylindrical inner liner (4), and forms a cylindrical member (7) by combining the carcass ply (3) with the inner liner (4). A third forming drum (23) forms a cylindrical side member (5), and forms a carcass band (8) by combining the cylindrical member (7) with the side member (5). A conveyance device (30) conveys the carcass ply (3) from the first forming drum (21) to the second forming drum (22), and conveys the cylindrical member (7) from the second forming drum (22) to the third forming drum (23). The third forming drum (23) is disposed below the accommodation space of the first forming drum (21) and the second forming drum (22).
