Abstract
A method of manufacturing a smoking article that contains, as members, at least a tobacco rod, a cooling segment, and a filter segment and in which a low-stiffness member L and a high-stiffness member H are adjacent to each other, the method includes (A) placing an adhesive on either surface of a tipping paper to form each portion of a high adhesive weight and a low adhesive weight per unit area after solidification, where the portion of a high adhesive weight is provided in a region for wrapping the member L; and (B) preparing a composite segment that contains at least the tobacco rod, the cooling segment, and the filter segment and wrapping the composite segment in the tipping paper.
Claims35
A method of manufacturing a smoking article that includes, as members, at least a tobacco rod, a cooling segment, and a filter segment and in which a low-stiffness member L and a high-stiffness member H having a greater stiffness than the low-stiffness member L are adjacent to each other, the method comprising
- (A) placing an adhesive on either surface of a tipping paper to form each portion of a first adhesive weight and a second adhesive weight per unit area after solidification, the first adhesive weight being greater than the second adhesive weight, wherein the portion of first adhesive weight is provided in a region for wrapping the member L;
- and
- (B) preparing a composite segment that includes at least the tobacco rod, the cooling segment, and the filter segment and wrapping the composite segment in the tipping paper,
- wherein in the step of A, the portion of the first adhesive weight is provided in a region extending from a contact face between the member L and the member H to a 20 to 40% position of the member L in the longitudinal direction.
A smoking article comprising, as members, at least a tobacco rod, a cooling segment in contact with the tobacco rod, a filter segment, and a tipping paper for wrapping the tobacco rod, the cooling segment, and the filter segment and comprising a low-stiffness member L adjacent to a high-stiffness member H, wherein
- the tipping paper has each portion of a first adhesive weight and a second adhesive weight per unit area after solidification, the first adhesive weight being greater than the second adhesive weight;
- and
- the tipping paper includes the portion of the first adhesive weight in a region for wrapping the member L,
- wherein the portion of the first adhesive weight is provided in a region extending from a contact face between the tobacco rod and a member immediately adjacent the tobacco rod to a 20 to 40% position of the tobacco rod in the longitudinal direction.
A method of manufacturing a smoking article that includes, as members, at least a tobacco rod, a cooling segment, and a filter segment, comprising
- (A′) placing an adhesive on either surface of a tipping paper to form each portion of a first adhesive weight and a second adhesive weight per unit area after solidification, the first adhesive weight being greater than the second adhesive weight, wherein the portion of the first adhesive weight is provided in a region for wrapping the tobacco rod;
- and
- (B′) preparing a composite segment that includes at least the tobacco rod, the cooling segment, and the filter segment and wrapping the composite segment in the tipping paper,
- wherein in the step of A′, the portion of the first adhesive weight is provided in a region extending from a contact face between the tobacco rod and a member immediately adjacent the tobacco rod to a 20 to 40% position of the tobacco rod in the longitudinal direction.
A smoking article comprising, as members, at least a tobacco rod, a cooling segment, a filter segment, and a tipping paper for wrapping the tobacco rod, the cooling segment, and the filter segment, wherein
- the tipping paper has each portion of a first adhesive weight and a second adhesive weight per unit area after solidification, the first adhesive weight being greater than the second adhesive weight;
- and
- the tipping paper includes the portion of the first adhesive weight in a region for wrapping the tobacco rod,
- wherein the portion of the first adhesive weight is provided in a region extending from a contact face between the tobacco rod and a member immediately adjacent the tobacco rod to a 20 to 40% position of the tobacco rod in the longitudinal direction.
