  • Step A is performed in any appropriate manner but is preferably preformed through the following steps ( Fig. 3 );
  • step A1 can be performed in the first unit 81 of Fig. 7 where 81f is a feeder for tobacco rods 1, 81p is a picking-up drum, and 81s is a separating drum. A pair of tobacco rods 1 fed from the feeder 81f are passed to a holding section provided on the circumferential surface of the picking-up drum 81p.
  • the pair of the tobacco rods 1 are passed to the separating drum 81s and separated in a holding section while being transferred.
  • one or a plurality of drums may have a feeding, receiving, transferring, or separating function.
  • Step A2 can be performed in the second unit 82 of Fig. 7 where 82f is a feeder for a double-length cooling segment 3w, 82t is a transfer drum, 82p is a picking-up drum, and 82a is a receiving drum.
  • the pair of the tobacco rods 1 placed via a gap are passed in this state to the transfer drum 82t.
  • a double-length cooling segment 3w fed from the feeder 82f is passed to a holding section provided on the circumferential surface of the picking-up drum 82p and then passed to the receiving drum 82a.

Subsequently, the segment is passed to the separating drum 83s and placed via a gap.
  • step A is preferably performed through the following steps ( Fig. 4 );
  • step A2' the double-length cooling segment 3w' cut in advance
  • cutting failure can be avoided even if the cooling segment is formed from a hard-to-cut material.
  • double-length segment cut in advance there is also an advantage that the entire length of a machine for performing this method can be shortened.
  • step A is preferably performed through the following steps ( Fig. 5 );
  • step A1 Since the distance between the tobacco rods is long in step A1, the number of times the tobacco rods are moved can be reduced in this method. Consequently, there is an advantage that the damage to tobacco rods can be avoided during high-speed manufacture or the like.
  • Step A has an advantage, in addition to the foregoing, that the height of an apparatus body can be reduced in an apparatus for performing this method since cutting is performed after placing each member. For example, when cutting is performed before placing a member in the above-described apparatus, it is necessary to provide a drum for cutting the member above a drum for transferring the member. As a result, the apparatus body becomes high since a cutting drum needs to be added in the height direction of the apparatus. Meanwhile, since cutting is performed after placing each member, step A can reduce the height of an apparatus body.
  • a double-length filter segment 5w which has a double length of the filter segment 5 is prepared and placed in the gap such that both ends of the double-length filter segment 5w come into contact with the end of either of the tobacco segments 1, thereby preparing a composite segment.

  • the composite segment is integrated by wrapping in one tipping paper 7 to obtain a double-length smoking article 100w.
  • the tipping paper any paper common in the field concerned can be used.
  • the tipping paper may be coated with a publicly known adhesive.
  • the composite segment in the separable state is integrated into the inseparable state.
  • the tipping paper 7 need not cover the entire range of the tobacco rods 1.
  • the region covered with the tipping paper 7 is preferably a region extending from the bonding face between the tobacco rod 1 and the cooling segment 3 to the position of 0.2X to 0.4X in the longitudinal direction of the tobacco rod 1.
  • thermal conductivity can be enhanced in the case of heating the tobacco rod 1 from the outside.
  • This step can be performed in the fifth unit 85 of Fig. 7 .
  • 85f is a feeder for a tipping paper 7
  • 85t is a transfer drum
  • 85r is a rolling drum
  • 85h is a rolling hand.
  • a rolling drum is a drum having a holding section that is for holding a member on the circumferential surface and that enables a segment or another member to rotate on its central axis in the longitudinal direction.
  • a rolling hand is a means that is disposed facing the circumferential surface of the rolling drum and that is for forming a gap of a constant distance from the circumferential surface.
  • the composite segment 90 is passed to the transfer drum 85t and then passed to the rolling drum 85r.
  • the precursor 92 includes the tipping paper 7 attached, like a flag, to the composite segment 90. In other words, part of the tipping paper 7 is attached to the circumferential surface of the composite segment 90 while leaving the remainder free.
  • the precursor 92 is fixed to the holding section on the circumferential surface of the rolling drum 85r through suction or the like and transferred to the gap formed between the rolling drum 85r and the rolling hand 85h. While passing through this gap, the entire circumferential surface of the precursor 92 is wrapped in the tipping paper 7 to form a double-length smoking article 100w (see Fig. 8 ).
  • the tobacco rod 1 preferably has a diameter larger than the neighboring cooling segment 3 in the present invention.
  • the surfaces of the rolling drum 85r and the rolling hand 85h are flat, excessive contact arises between these surfaces and the tobacco rod 1 ( Fig. 9 (1)). This results in a problem of falling fillings from the leading end under the impact on the tobacco rod 1.
  • the difference in circumference causes twisting, thereby developing defects, such as creases, in a product.
  • a depression may be provided on the rolling drum 85r or both the rolling drum and the rolling hand.
  • the depth of the depression (T in Figs. 9(2) and ( 3 )) is appropriately adjusted and is preferably 0.05 to 0.15 mm.
  • Such a depression need not be provided on the entire surface that faces the tobacco rod 1.
  • a depression may be provided on part of the surface that faces the tobacco rod 1. Meanwhile, to reliably attach a tobacco rod to another member by using a tipping paper, a depression is preferably absent near the boundary between these two members.
  • the double-length smoking article 100w is cut in the central part in the longitudinal direction.
  • a pair of smoking articles 100 can be manufactured.
  • This step may further include aligning two smoking articles 100 in the same direction by inverting either of the smoking articles 100.
  • This step can be performed in the sixth unit 86 of Fig. 7 .
  • 86c is a cutter drum
  • 86c' is a cutter
  • 86a is a receiving drum.
  • the double-length smoking article 100w is passed to the cutter drum 86c and cut in the central part in the longitudinal direction to form smoking articles 100.
  • the smoking articles 100 are passed to the receiving drum 86a, separated, and isolated as products.
  • the present invention even when a member having a smaller diameter than a tobacco rod is placed neighboring the tobacco rod, it is possible to avoid failure, such as jams during rolling, and consequently to perform satisfactory rolling. Moreover, the present invention is also advantageous in terms of costs since one tipping paper is used. Further, conventional methods that use a plurality of tipping papers need a measure of providing steps on drums, for example, since steps are formed on smoking articles. In contrast, the manufacturing method of the present invention does not need such a measure.
  • Tobacco rod of 7.0 mm in diameter and 20.0 mm in length (from Japan Tobacco Inc.)
  • Double-length filter segment of 6.9 mm in diameter consisting of a center hole filter (8.0 mm)/a double-length acetate filter (14.0 mm)/a center hole filters (8.0 mm)
