Rolling unit and rolling method for filler rod

Abstract

A rolling unit for a filler rod includes a rolling drum that has an outer peripheral surface for holding chip paper and a continuous body and transfers the chip paper and the continuous body in the circumferential direction of the outer peripheral surface; and a rolling block that has a rolling surface facing the outer peripheral surface of the rolling drum, forms a rolling gap between the rolling surface and the outer peripheral surface of the rolling drum, and winds the chip paper around the continuous body by rolling the continuous body while interposing the continuous body in the rolling gap as the rolling drum rotates. A plurality of block-side suction holes is opened on the rolling surface of the rolling block, and the rolling gap is suctioned via the block side suction holes.

1 . A rolling unit for a filler rod, the rolling unit forming a serial body in which a plurality of rods including a filler rod filled with a flavor raw material is disposed so as to be coaxially arranged, the rolling unit forming an intermediate product of a flavor inhaling article by connecting the serial body by rolling the serial body to wrap the serial body with a tipping paper during the rolling, the rolling unit comprising:
 a rolling drum that has an outer periphery holding the tipping paper and the serial body and that conveys the tipping paper and the serial body in a circumferential direction of the outer periphery; and   a rolling block that has a rolling surface facing the outer periphery of the rolling drum, the rolling block forming a rolling space between the rolling surface and the outer periphery of the rolling drum, the rolling block wrapping the serial body with the tipping paper by sandwiching and rolling the serial body in the rolling space with rotation of the rolling drum, wherein   the rolling block has a plurality of block-side suction holes open at the rolling surface, the rolling space is sucked via the block-side suction holes.   
     
     
         2 . The rolling unit for a filler rod according to  claim 1 , wherein the block-side suction holes are open at the rolling surface in a region where the filler rod is positioned. 
     
     
         3 . The rolling unit for a filler rod according to  claim 2 , wherein the block-side suction holes are open at the rolling surface in a region where the rod other than the filler rod is positioned. 
     
     
         4 . A rolling method for a filler rod, the rolling method forming a serial body in which a plurality of rods including a filler rod filled with a flavor raw material is disposed so as to be coaxially arranged, the rolling method forming an intermediate product of a flavor inhaling article by connecting the serial body by rolling the serial body to wrap the serial body with a tipping paper during the rolling, the rolling method comprising:
 a conveying step of conveying the tipping paper and the serial body in a circumferential direction of the outer periphery by using a rolling drum that has an outer periphery that holds the tipping paper and the serial body; and   a rolling step of, by using a rolling block that has a rolling surface facing the outer periphery of the rolling drum and that forms a rolling space between the rolling surface and the outer periphery of the rolling drum, wrapping the serial body with the tipping paper by sandwiching and rolling the serial body in the rolling space with rotation of the rolling drum, wherein   the rolling step includes a suction process of sucking the rolling space via a plurality of block-side suction holes that are open at the rolling surface of the rolling block.   
     
     
         5 . The rolling method for a filler rod according to  claim 4 , wherein, in the suction process, the rolling space is sucked via the block-side suction holes that are open at the rolling surface in a region where the filler rod is positioned. 
     
     
         6 . The rolling method for a filler rod according to  claim 5 , wherein, in the suction process, the rolling space is sucked via the block-side suction holes that are open at the rolling surface in a region where the rod other than the filler rod is positioned.
