An anvil 200 includes a base 210 and projections 220 and 230. The base 210 is installed at an attachment position 112a on an outer peripheral surface 112 of a rotating drum 110. The projection 220 protrudes from a front surface 210a of the base 210 in a normal direction H of the rotating drum 110 and is formed in a line shape extending in the cross direction CD along the front surface 210a of the base 210. On the front surface 210a of the base 210, one end 220a in the cross direction CD of the projection 220 is provided forward of the other end 220b in a rotation direction R. In the projection 220, a cut portion 260 is formed to extend in a direction opposite to the protrusion direction of each protrusion 240. The cut portion 260 extends from the front surface of the projection 220, protruding from the front surface 210a of the base 210, to the vicinity of the middle of the projection 220.
