  • the leading end refers to a region of the tip paper positioned at the forefront on the tobacco rod side when wound with the tip paper. This is to prevent the adhesive from oozing out of the tip of the chip paper 7 during wrapping.
  • the length u of the non-bonded portion 1n in the longitudinal direction of the chip paper 7 is preferably 0.1 to 1.0 mm.
  • the tip paper 7 preferably has a non-adhered portion 3n in a region where the cooling segment 3 is wrapped.
  • ventilation can be easily provided in the cooling segment 3 when the smoking article 100 is formed.
  • the ventilation can be provided by laser processing after manufacturing the smoking article 100, for example.
  • the non-adhered portion 3n can be printed. For example, if a code indicating a manufacturing machine is printed on the non-adhesive portion 3n, the code can be read when the chip paper 7 is peeled off after winding.
  • the non-adhered portion 3n has a starting point at a position of 40 to 50% in the longitudinal direction of the cooling segment 3 with respect to a contact surface (point O) of the tobacco rod 1 with the cooling segment 3, and has an end point of 70 to 90%. Preferably, it is present in the region. That is, it is preferable that the non-adhesive portion 3n exists in a region starting from 0.4 to 0.5Y and ending from 0.7 to 0.9Y in FIG. By providing the non-adhesive portion 3n in this manner, it is possible to suppress a decrease in the adhesive force of the entire chip paper.
  • the number of non-adhesive portions 3n may be two in the circumferential direction as shown in FIG. 2, or may be one.
  • the total length of the non-adhesive portion 3n in the circumferential direction (t1 + t1 in FIG. 2B) is preferably 50 to 80% of the circumferential length P of the chip paper 7.
  • the distance t2 from the circumferential end to the non-adhesive portion 3n is preferably 5 to 10% of P.
  • the distance t3 between the two is appropriately adjusted by t1 and t2.
  • the tip paper 7 preferably has a non-adhesive portion 5n near the end of the filter segment 5.
  • the smoking article 100 may be manufactured by preparing a double-length smoking article 100w and cutting the same, but in this case, it is easy to cut and the adhesive adheres to the cutter. This is because it can be prevented.
  • the length v of the non-adhesive portion 5n in the longitudinal direction of the chip paper 7 is preferably 0.5 to 1.0 mm.
  • the length of the tip paper 7 in the longitudinal direction may be a length from the mouth end of the filter segment 5 to a range of 0.42X to 0.6X in the longitudinal direction of the tobacco segment 1.
  • Step B the composite segment 90 is wrapped with chip paper for 7 times.
  • the double-length composite segment 90w may be wrapped with chip paper seven times.
  • the smoking article 100 is obtained by cutting after wrapping.
  • Wrapping can be performed according to a known method. For example, as shown in FIG. 8, this step is performed using an apparatus having a plurality of drums.
  • reference numeral 80f denotes a supply device for the chip paper 7
  • 80t denotes a transfer drum
  • 80r denotes a rolling drum
  • 80h denotes a rolling hand.
  • the rolling drum is a holding unit that holds a member on a circumferential surface, and is a drum including a holding unit that allows a member such as a segment to rotate around a central axis in the longitudinal direction.
  • the rolling hand is means for forming a gap having a certain distance between the rolling hand and the circumferential surface of the rolling drum.
  • the segment including the tobacco rod 1, the cooling segment 3, and the filter segment 5 is referred to as a composite segment 90.
  • the composite segment 90 is transferred from the transfer drum 80t to the rolling drum 80r.
  • a part of the chip paper 7 supplied from the supply device 80f is adhered to the circumferential surface of the segment on the rolling drum 80r to form a precursor 92 (see FIG. 9).
  • the precursor 92 includes the chip paper 7 adhered to the composite segment 90 like a flag. That is, a part of the chip paper 7 is adhered to the circumferential surface of the composite segment 90, but the other part is free.
  • the precursor 92 is fixed to a holding portion on the circumferential surface of the rolling drum 80r by suction or the like, and is transferred to a gap formed between the rolling drum 80r and the rolling hand 80h. When passing through the gap, the entire circumferential surface of the precursor 92 is wrapped with the tip paper 7 to form the smoking article 100 (see FIG. 9).
  • the diameter of the tobacco rod 1 is preferably larger than the diameter of the cooling segment 3 adjacent thereto.
  • the surfaces of the rolling drum 80r and the rolling hand 80h are flat, the surfaces and the tobacco rod 1 come into excessive contact (FIG. 10A), and the tobacco rod 1 is subjected to an impact. This causes a problem of so-called dropping of the packing material. Further, twisting due to the circumferential difference occurs, and defects such as wrinkling of the product occur. Therefore, in the present invention, as shown in FIGS. 10 (2) and (3), a concave portion is provided on the surface of the rolling drum 80r or the rolling hand 80h facing the tobacco rod 1 so that a gap is formed between the rolling drum 80r and the tobacco rod 1.
  • FIGS. 10 (2) and 10 (3) show a mode in which a concave portion is provided in the rolling hand 80h, but the concave portion may be provided in the rolling drum 80r or both.
  • the depth of the recess (T in FIGS. 10 (2) and (3)) is appropriately adjusted, but is preferably 0.05 to 0.15 mm.
  • the recess need not be provided on the entire surface facing the tobacco rod 1.
  • the concave portion may be provided on a part of the surface facing the tobacco rod 1. However, in order to securely bond the tobacco rod and another member with the tip paper, it is preferable that there is no recess near the boundary between the two members.
  • Example 1 The following members were prepared.
  • a tobacco rod with a diameter of 7.0 mm and a length of 20.0 mm (manufactured by Japan Tobacco Inc.)
  • a paper tube with a diameter of 6.9 mm and a length of 20.0 mm, a diameter of 6.9 mm consisting of a center hole (8.0 mm) / double-length acetate filter (14.0 mm) / center hole (8.0 mm) Long filter segment
  • ⁇ ⁇ ⁇ Tip paper shown in FIG. 3 was prepared. The dimensions are shown in Table 1. An adhesive was applied to the chip paper. The thickness of the adhesive layer in the unsolidified state and the weight of the adhesive after solidification are shown in Table 1.
  • a double-length smoking article as shown in FIG. 3 was prepared. This was wrapped with the tip paper to obtain a smoking article. The obtained smoking article had good appearance without wrinkles. Further, the obtained smoking article had good neck-through resistance.
