Abstract (en)
A rolling unit 1 for a filler rod TR comprises: a rolling drum 2 that has an outer peripheral surface 2a for holding chip paper P and a continuous body A and transfers the chip paper P and the continuous body A in the circumferential direction of the outer peripheral surface 2a; and a rolling block 4 that has a rolling surface 4a facing the outer peripheral surface 2a of the rolling drum 2, forms a rolling gap 12 between the rolling surface 4a and the outer peripheral surface 2a of the rolling drum 2, and winds the chip paper P around the continuous body A by rolling the continuous body A while interposing the continuous body A in the rolling gap 12 as the rolling drum 2 rotates. A plurality of block-side suction holes 14 are opened on the rolling surface 4a of the rolling block 4, and the rolling gap 12 is suctioned via the block side suction holes 14.
