Abstract (en)

[origin: EP3861869A1] Provided is a method of manufacturing a smoking article that has a filter segment and a tobacco segment containing a tobacco rod and a cooling segment, including (A) preparing a double-length tobacco segment containing a double-length tobacco rod that has a double length of the tobacco rod and that is separable in the central part in the longitudinal direction and two cooling segments in contact with either end of the double-length tobacco rod; (B) separating the double-length tobacco segment in the central part to prepare a pair of separate tobacco segments and inverting the tobacco segments, thereby placing the tobacco segments via a gap to position the tobacco rod sections outside, align the longitudinal axes of the tobacco segments, and allow the cooling segments to face each other; (C) preparing a double-length filter segment, which has a double length of the filter segment, and placing the double-length filter segment in the gap such that both ends of the double-length filter segment come into contact with the end on the cooling segment side of either of the tobacco segments, thereby preparing a composite segment; (D) integrating the composite segment by wrapping in one tipping paper to produce a double-length smoking article, which has a double length of the smoking article; and (E) cutting the double-length smoking article in the central part in the longitudinal direction to yield smoking articles.
