In the absorber forming and transferring mechanism 100, at a core reception time, the rotational velocity V4 of the rotary transfer member 160 is same as the rotation velocity V3 of the forming drum 150. At a core transfer time, the rotational velocity V5 of the rotary transfer member 160 is same as the conveyance velocity V2 of the web 9A. During a period from the core reception time to the core transfer time, the rotational velocity V5 of the rotary transfer member 160 becomes higher than the rotational velocity V3 of the forming drum 150. During a period from the core transfer time to the core reception time, the rotational velocity V5 of the rotary transfer member 160 becomes lower than the conveyance velocity V2 of the web 9A.
