A preceding carcass cord from one feeding unit is used to form a carcass layer while being fed to a forming drum, and a leading edge portion of a next carcass cord is paid out from another feeding unit in advance. When a predetermined length of the preceding carcass cord is fed, a splice mechanism is used to join the leading edge portion of the next carcass cord to the preceding carcass cord to make the leading edge portion of the next carcass cord continuous with the preceding carcass cord. Then, with the next carcass cord fed to the forming drum, formation of the carcass layer is continued to complete the carcass layer.
