Therein, the step of positioning the continuous profile of susceptor in the aerosol-forming tobacco substrate is performed before performing the step of converging the aerosol-forming tobacco substrate to its final rod shape. ## Claims ### Claim 1 Inductively heatable smoking article comprising an inductively heatable tobacco segment of an inductively heatable tobacco rod, wherein the inductively heatable tobacco segment comprises an aerosol-forming tobacco substrate and a susceptor element in the form of a band, wherein the inductively heatable tobacco segment is provided with a longitudinally running folding structure, wherein the susceptor element in the form of a band is arranged parallel to and in between folds of the longitudinally running folding structure of the inductively heatable tobacco segment; and wherein a length of the susceptor element in the tobacco segment is equal to the length of the tobacco segment. ### Claim 2 (depends on 1) Inductively heatable smoking article according to claim 1, wherein the susceptor element has a rectangular shape. ### Claim 3 (depends on 1) Inductively heatable smoking article according to claim 1, wherein the susceptor element is positioned in a central portion of the inductively heatable tobacco segment. ### Claim 4 (depends on 1) Inductively heatable smoking article according to claim 1, wherein the susceptor element is arranged along a longitudinal axis of the inductively heatable tobacco segment. ### Claim 5 (depends on 1) Inductively heatable smoking article according to claim 1, wherein the longitudinally running folding structure provides the inductively heatable tobacco segment with a wave-like cross-section. ### Claim 6 (depends on 1) Inductively heatable smoking article according to claim 1, wherein the inductively heatable tobacco segment is made from of a gathered sheet. ### Claim 7 (depends on 6) Inductively heatable smoking article according to claim 6, wherein the sheet is a gathered sheet of homogenized tobacco material. ### Claim 8 (depends on 1) Inductively heatable smoking article according to claim 1, wherein the inductively heatable tobacco segment has a length in a range between 2 millimeter and 20 millimeter. ### Claim 9 (depends on 1) Inductively heatable smoking article according to claim 1, wherein the susceptor element has a width that is smaller than a diameter of the inductively heatable tobacco segment. ### Claim 10 (depends on 1) Inductively heatable smoking article according to claim 1, wherein a width of the susceptor element is between about 2 millimeter and about 8 millimeter. ### Claim 11 (depends on 1) Inductively heatable smoking article according to claim 1, wherein a thickness of the susceptor element is between about 0.03 millimeter and about 0.15 millimeter. ### Claim 12 (depends on 1) Inductively heatable smoking article according to claim 1, wherein the susceptor element is a multi-layer susceptor. ### Claim 13 (depends on 1) Inductively heatable smoking article according to claim 1, wherein the inductively heatable tobacco segment is attached to a mouthpiece. ### Claim 14 Inductively heatable smoking article comprising an inductively heatable tobacco segment of an inductively heatable tobacco rod, the inductively heatable tobacco rod manufactured by: providing a continuous profile of a susceptor;
