## Abstract

The method for manufacturing inductively heatable tobacco rods comprises the steps of providing a continuous profile of a susceptor and cutting the continuous profile of susceptor into individual susceptor segments. The method further comprises the steps of guiding an aerosol-forming tobacco substrate along a tobacco substrate converging device, positioning the individual susceptor segments in the aerosol-forming tobacco substrate and converging the aerosol-forming tobacco substrate to a final rod shape. Therein, the step of positioning the individual susceptor segments 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

Method for manufacturing inductively heatable tobacco rods, the method comprising the steps of:
providing a continuous profile of a susceptor;
cutting the continuous profile of susceptor into individual susceptor segments;
guiding an aerosol-forming tobacco substrate along a tobacco substrate converging device;
positioning the individual susceptor segments in the aerosol-forming tobacco substrate;
converging the aerosol-forming tobacco substrate to a final rod shape, wherein the step of positioning the individual susceptor segments in the aerosol-forming tobacco substrate is performed before performing the step of converging the aerosol-forming tobacco substrate to its final rod shape.

### Claim 2 (depends on 1)

Method according to claim 1, wherein the step of positioning the individual susceptor segments in the aerosol-forming tobacco substrate comprises positioning the individual susceptor segments in a central portion of the tobacco substrate.

### Claim 3 (depends on 1)

Method according to claim 1, wherein the method further comprises the step of providing the tobacco substrate with a longitudinally running folding structure, and wherein the step of positioning the individual susceptor segments in the tobacco substrate comprises arranging the individual susceptor segments parallel to and in between the longitudinally running folding structure of the tobacco substrate.

### Claim 4 (depends on 1)

Method according to claim 1, wherein the step of cutting of the continuous profile of susceptor into individual susceptor segments is performed while guiding the continuous profile of susceptor along a surface of a cutting support.

### Claim 5 (depends on 4)

Method according to claim 4, wherein the step of cutting the continuous profile of susceptor into individual susceptor segments is performed by impacting a cutting blade against the continuous profile of susceptor while the continuous profile of susceptor is guided along the surface of the cutting support.

### Claim 6 (depends on 4)

Method according to claim 4, further comprising the step of transferring the individual susceptor segments from the cutting support to an insertion device.

### Claim 7 (depends on 6)

Method according to claim 6, further comprising the step of separating the individual susceptor segments while preforming the step of transferring the individual susceptor segments from the cutting support to the insertion device.

### Claim 8 (depends on 1)

Method according to claim 1, further comprising the step of forming a channel in partially converged aerosol-forming tobacco substrate and positioning the individual susceptor segments in the channel.

### Claim 9 (depends on 1)

Method according to claim 1, wherein the step of providing a continuous profile of a susceptor comprises providing a continuous sheet of susceptor.

### Claim 10 (depends on 1)

Method according to claim 1, further comprising the step of wrapping the inductively heatable tobacco rod in a wrapper material.

### Claim 11 (depends on 1)

Method according to claim 1, further comprising the step of cutting the inductively heatable tobacco rod at positions between subsequent susceptor segments in the tobacco rod.

### Claim 12 (depends on 11)

Method according to claim 11, therein cutting the inductively heatable tobacco rod into inductively heatable tobacco segments of equal length.
