Abstract
A web is reeled onto successive reeling drums to form respective jumbo rolls by reeling the web onto a first reeling drum at a reeling position to form a first jumbo roll, the first reeling drum being driven by a center drive. When the first jumbo roll is full, a second reeling drum is delivered to a standby position and is accelerated to web speed. A transfer device is employed to transfer the first jumbo roll to an exchange position while the center drive remains connected thereto. The second reeling drum is transferred to the reeling position and the web is exchanged from the first jumbo roll to the second reeling drum. The first jumbo roll is decelerated and the transfer device is shifted from the first jumbo roll to the second reeling drum. The center drive is connected to the second reeling drum.
