Applying an additive from radially outside upon production of an aerosol-generating rod
A device ( 1 ) for producing an aerosol-generating rod ( 3 ) comprises a converging device ( 5 ), a susceptor guide ( 19 ), and a conveyor system. The converging device has a forming space converging along an axial direction ( 17 ). The susceptor guide extends into the forming space of the converging device and comprises an exit opening ( 21 ) for a susceptor ( 23 ) within the forming space ( 9 ) of the converging device. The conveyor system is configured to convey filling material ( 15 ), preferably formed as a sheet, through the forming space of the converging device to shape the filling material into a rod incorporating the susceptor. The device further comprises at least one additive supply line ( 29 ) having a dispensing opening that opens into the forming space of the converging device radially outward of the susceptor guide.
1 . Device for producing an aerosol-generating rod, comprising:
a converging device with a forming space converging along an axial direction;
a susceptor guide extending into the forming space of the converging device and comprising an exit opening for a susceptor within the forming space of the converging device;
a conveyor system configured to convey filling material through the forming space of the converging device to shape the filling material into a rod incorporating the susceptor;
at least one additive supply line having a dispensing opening that opens into the forming space of the converging device radially outward of the susceptor guide; and
a first additive reservoir and a second additive reservoir, the first additive reservoir being connected to a first additive supply line of the at least one additive supply line and the second additive reservoir being connected to a second additive supply line of the at least one additive supply line.
2 . Device according to claim 1 , wherein the at least one additive supply line protrudes into the forming space of the converging device by no more than 20 millimeters, or no more than 10 millimeters, or no more than 5 millimeters, or no more than 3 millimeters, or no more than 2 millimeters, or no more than 1 millimeter.
3 . Device according to claim 1 , wherein the at least one additive supply line is inclined at the dispensing opening into the axial direction, as compared to a direction perpendicular to the axial direction.
4 . Device according to claim 1 , wherein the dispensing openings of at least two of the additive supply lines are arranged at different circumferential positions around the axial direction.
5 . Device according to claim 1 , wherein a first dispensing opening of an additive supply line of the at least one additive supply line and a second dispensing opening of another additive supply line of the at least one additive supply line are located on opposing sides with respect to the susceptor guide.
6 . Device according to claim 1 , wherein a dispensing opening of an additive supply line of the at least one additive supply line is upstream of a dispensing opening of another additive supply line of the at least one additive supply line with respect to the axial direction.
