This will be described later in the third embodiment (see FIG. 30). That is, in this embodiment, the mouthpiece segment 14 and the filter segment 20 will be described as being the same thing.
  • the length of the rod of the mouthpiece segment 14 is preferably, for example, 10 mm to 50 mm, and more preferably, approximately 25 mm to 30 mm.

  • a flavor product 10 is formed in which the rods of the flavor generating segment 12 and the rods of the mouthpiece segment 14 are aligned in the axial direction.
  • the filter segment 20 includes a filter material 22 and a wrapper 24 that wraps around the outside of the filter material 22 to form the filter segment 20 into a rod.
  • the filter material 22 of the filter segment 20 is formed by processing a sheet material 30 so that it has a large number of non-annular through-slits 32.
  • the large number of through-slits 32 are assumed to be of the same size, shape, and disposed at equal intervals.
  • the non-annular through cuts 32 are formed while leaving portions integral with the sheet material 30, and do not form a closed figure. These through cuts 32 each form a tongue (flap) 33 integral with the sheet material 30. Although the through cuts 32 are integrally connected to the sheet material 30, they are formed so as to protrude from the surface of the sheet material 30 (holeless region 34) when the sheet material 30 is folded from a flat surface. Therefore, when the sheet material 30 is folded and formed into a rod (rod for flavored product), at least a portion of the tongue 33 does not follow the surface of the sheet material 30, and may deviate from the surface of the sheet material 30 and protrude due to the rigidity of the sheet material 30 (tongue 33) itself.
  • the holeless region 34 of the sheet material 30 is formed as a closed region (partition) that has no holes penetrating in the Z-axis direction at any position in the region defined by the longitudinal and width directions of the sheet material 30.
  • the segment S of the sheet material 30 forms the filter material 22 of the filter segment 20.
  • One segment S of the sheet material 30 is creped (shrunk) such as gathered and folded in the width direction (Y-axis direction) of the sheet material 30 so that the longitudinal direction of the rod of the filter segment 20 is aligned in the direction in which the through-cut portion 32 and the holeless region 34 are adjacently arranged, that is, a cylindrical rod is formed from the filter material 22 by the folding process.
  • a large number of ridges 31 (valley fold portion (fold line) 31a, mountain fold portion (fold line) 31b) (see Figures 3 and 9A) are formed along the X-axis direction and in the Y-axis direction, for example, at appropriate intervals, and by performing the folding process in which these ridges 31 are actually mountain and valley folded, the width in the width direction of one segment S of the sheet material 30 becomes smaller, and a cylindrical rod is formed from the filter material 22 while maintaining the longitudinal length of one segment S.
  • the filter segment 20 is formed as a cylindrical rod or rod segment by wrapping the outer circumference of the cylindrical filter material 22 with a wrapper 24.
  • the spacing between the numerous creases 31 (valley folds 31a, mountain folds 31b) may be uniform or random.
  • the tongue pieces 33 that are provided to protrude from the sheet material 30 in a direction intersecting the axial direction (X-axis direction) of the rod define a closed figure by an imaginary fold line (mountain fold line 31b in FIG. 3) and a through cut portion 32.
  • a virtual rectangle (frame F) that circumscribes the tongue pieces 33 that include the closed figure is defined, one side S1 of the rectangle (frame F) is parallel to the fold line and is parallel or approximately parallel to the axial direction of the rod.
  • the rod of the filter segment 20 is formed as a region of low airflow resistance along the axial direction because the through cut portion 32 increases the flow path in the rod compared to the holeless region 34.
  • the rod of the filter segment 20 is formed as a region of high airflow resistance along the axial direction because the flow path in the rod is restricted in the holeless region 34 compared to the through cut portion 32. Therefore, by arranging the through cut portion 32 and the holeless region 34 adjacently along the axial direction of the rod of the filter segment 20, a region of relatively low airflow resistance and a region of relatively high airflow resistance are formed in the filter material 22 of one segment S of one sheet material 30.
  • the filter segment 20 adjusts the airflow resistance along the longitudinal direction with one member (the filter material 22 of one segment S of the sheet material 30), and the presence of the through-slits 32 allows the formation of an area of low airflow resistance.
  • a flavored product 10 equipped with such a filter segment 20 can be provided.
  • the airflow resistance of the filter material 22 of the filter segment 20 not only depends on the selection of the sheet material 30, but is also adjusted by, for example, setting the crepe depth (see Figures 6 and 6B) of a pair of crepe rollers 64a, 64b in the crepe section (crimping section) 64 of the manufacturing device 50 (see Figure 5), which will be described later.
  • the difference in air flow resistance per mm of the rod of the filter segment 20 between the first segment (through cut portion) 32 and the second segment (holeless region) 34 is 0.5 mmH 2 O/mm to 10 mmH 2 O/mm, and preferably 1 mmH 2 O/mm to 5 mmH 2 O/mm.
  • the wrapper 24 may be any wrapping paper. To maintain the appropriate stiffness of the filter segment 20, wrapping paper with a larger basis weight (thick paper) may be used.
  • the basis weight of the wrapper 24 is preferably 30 gsm or more, more preferably 50 gsm, and even more preferably 100 gsm or less.

  • the supply section 52, processing section 54, rod forming section 56, rod cutting section 58, and optical inspection device 60 are controlled by a control device (not shown). It is preferable that the control device of the manufacturing apparatus 50 appropriately controls the supply section 52, processing section 54, rod forming section 56, and rod cutting section 58, for example by feedback control, based on information from a control section 60c of the optical inspection device 60, which will be described later.
