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

Method for manufacturing inductively heatable tobacco rods

The present invention relates to a method for manufacturing inductively heatable aerosol-forming rods (). The method comprises the steps of supplying a continuous susceptor profile () to a continuous rod-forming process such as to enter and pass the rod-forming process along a center axis () of the rod-forming process, supplying a continuous substrate web () comprising an aerosol-forming substrate to the continuous rod-forming process such as to enter the rod-forming process laterally to the susceptor profile and passing the substrate web and the susceptor profile through the rod-forming process, thereby gathering the substrate web into a rod shape around the susceptor profile substantially coaxially to the center axis. The invention further relates to an apparatus () for manufacturing inductively heatable aerosol-forming rods (). The apparatus comprises a rod-forming device () configured for gathering a continuous substrate web () comprising an aerosol-forming substrate into a rod shape around a continuous susceptor profile () coaxially to a center axis () of the rod-forming device as the substrate web and the susceptor profile pass through the rod-forming device. The apparatus further comprises a susceptor supply () configured for supplying the susceptor profile to the rod-forming device such as to enter and pass the rod-forming device along the center axis of the rod-forming device. The apparatus also comprises a substrate supply () configured for supplying the substrate web to the rod-forming device such as to enter the rod-forming device laterally to the susceptor profile.

Method and apparatus for manufacturing inductively heatable aerosol-forming rods

The present invention relates to a method for manufacturing inductively heatable aerosol-forming rods (). The method comprises supplying a first substrate web () and a second substrate web () separately to a continuous multiple-stage rod-forming process which comprises at least a first and a subsequent second stage. The method further comprises supplying a continuous susceptor profile () to the rod-forming process such that the susceptor profile passes through at least the second stage. Furthermore, the method comprises passing the first and second substrate web separately through the first stage. Thereby, the first and the second substrate web are separately pre-gathered transversely with regard to a respective transport direction of each of the substrate web through the first stage. The method further comprises passing the susceptor profile and the pre-gathered substrate webs through the second stage. Thereby, the separately pre-gathered substrate webs are jointly gathered into a rod shape around the susceptor profile. The invention further relates to a multi-stage rod-forming device () comprising at least a first stage () and a second stage () downstream of the first stage. The first stage is configured for separately pre-gathering a first and a second substrate web () respectively as each of them passes through the first stage. The second stage is configured for jointly gathering the pre-gathered substrate webs into a rod shape around a susceptor profile () as the susceptor profile and the pre-gathered substrate webs pass through the second stage.

The method for manufacturing inductively heatable tobacco products comprises the steps of providing a tobacco product, providing a susceptor segment and positioning the susceptor segment in the tobacco product by moving the susceptor segment and the tobacco product relative to each other. Thereby the susceptor segment is pushed into the tobacco product.

Method for manufacturing inductively heatable tobacco products

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.
