Definitions
- the present invention relates to a method for producing a plurality of aerosol generating articles comprising a substrate section with an aerosol-forming substrate and a susceptor element.
- the present invention further relates to a system configured for producing the plurality of individual aerosol-generating articles.
- the present invention further relates to an aerosol-generating article comprising a substrate section with aerosol-forming substrate and a susceptor element.
- a lot of aerosol-generating articles, in particular heat-not-burn articles comprise a substrate section comprising aerosol-forming substrate and additional susceptor material.
- the susceptor is able to heat the aerosol-forming substrate to a temperature below combustion temperature of the substrate when subjected to an alternating electromagnetic field.
- a continuous substrate section including multiple individual substrate sections is produced, also containing a continuous band of susceptor material integrated within the aerosol-forming substrate.

- a method and a system for producing aerosol-generating articles which can increase the service life of the cutting tools.
- a method for producing individual aerosol-generating articles each article comprising an individual substrate section and the substrate section comprising aerosol-forming substrate with a susceptor is provided.
- the method may comprise a method step A) of providing a continuous band of susceptor material.
- the method may comprise a method step B) of partially cutting the continuous band of susceptor material at a predetermined precut position to produce a partially cut band of susceptor material.
- a method step C) may be included. This method step C) may comprise producing the aerosol-generating articles employing the partially band of susceptor material, wherein the precut position separates individual aerosol-generating articles from each other.
- a method for producing individual aerosol-generating articles comprises an individual substrate section and the substrate section comprises aerosol-forming substrate with a susceptor element.
- the method comprises the method steps of:
- the partially cut band of susceptor material may more easily be separated by a cutting tool at the precut position. This may be due to the partial cut introduced at the precut position. Completely cutting the partially cut band of susceptor material at the precut position may require less momentum of the cutting tool. This may reduce the danger of deformations or dislocations of the susceptor material within the substrate section.
- At least two precut positions may be formed in method step B).
- the positions of the precuts on the continuous band of susceptor material may be set in such a way that one individual substrate section is located between adjacent precut positions.
- one individual susceptor element corresponding to one individual substrate section may be located between adjacent precut positions.
- one individual substrate section may comprise one individual susceptor element.
- One individual susceptor element may be located between adjacent precut positions.
- a plurality of precut positions may be formed on the continuous band of susceptor material. If one individual susceptor element is located between adjacent precut positions, the plurality of precut positions may allow the easy formation of a plurality of individual susceptor elements by cutting the band of susceptor material at the plurality of precut positions.
- the plurality of precut positions may separate at least 50 individual susceptor elements, preferably between 10 and 50 individual susceptor elements from each other. Most preferably the plurality of precut positions separates 10 individual susceptor elements from each other
- the aerosol-forming substrate may be positioned around the partially cut band of susceptor material in a first embodiment. This may produce a continuous substrate section comprising the partially cut band of susceptor material. Subsequently the continuous substrate section may be cut at the precut position in order to produce individual aerosol-generating articles.
- a continuous substrate section comprising the partially cut band of susceptor material may be easier to cut at the precut positions compared to a continuous substrate section, including a continuous band of susceptor material without a precut.
- a plurality of precuts may be formed.
- the continuous substrate section may then be cut at all precut positions. This may produce a plurality of individual substrate sections, wherein each individual substrate section may comprise an individual susceptor element.
- the continuous substrate section may be cut at some precut positions. This may provide a plurality of multiple substrate sections. These multiple substrate sections may be further processed in order to produce aerosol-generating articles.
- the multiple substrate sections may each comprise a band of susceptor material, which still may include precut positions.
- One multiple substrate section may contain at least two, more preferably at least 5, or at least 10 individual substrate sections.
- the partially cut band of susceptor material may be completely cut at the predetermined precut position. This may produce individual susceptor elements. Subsequently the aerosol-forming substrate may be positioned around the individual susceptor elements. This may produce a continuous substrate section including individual susceptor elements. The individual susceptor elements may be spaced apart from each other. The individual susceptor elements therefore may not contact each other in the continuous substrate section.
- the individual susceptor elements in the continuous substrate section may each be spaced apart by gaps. Subsequently the continuous substrate section may be cut between the gaps of individual susceptor bands, thereby producing individual substrate sections.
- Such a continuous substrate section with individual susceptor elements may also ease the final cutting of the continuous substrate section.
- a cutting tool may only be required to cut through the aerosol-forming substrate in the continuous substrate section between individual susceptor elements without simultaneously cutting through the band of susceptor material. This may ease the cutting process and may not require as much force as cutting through the aerosol-forming substrate and the band of susceptor material. This may therefore reduce the risk of deformations and dislocations of the individual susceptor elements within the individual substrate sections. This may also increase the service life of the cutting tool.
- the continuous band of susceptor material may be partially cut by introducing incisions at the edge of the band. Subsequently during method step C) the partially cut band may be completely cut in a central part of the band adjacent to the incisions to produce the individual susceptor elements.
- This may enable completely cutting the continuous band of susceptor material in order to produce individual susceptor elements.
- This method in particular may require less force applied by the cutting tool compared to a method wherein the continuous band of susceptor material is completely cut in one step. This method may avoid deformations of the individual susceptor elements.
- the individual susceptor elements subsequently then may be incorporated into the continuous substrate section comprising the individual susceptor elements.
- the method of the present invention in general may provide two different alternative embodiments.
- One preferred first embodiment may be provided, wherein the partially cut band of susceptor material with the precuts is incorporated into aerosol-forming substrate. This produces a continuous substrate section comprising the partially cut band of susceptor material. This continuous substrate section can easily be further cut into individual substrate sections due to the precut positions.
- the other embodiment of the method of the present invention may provide a method wherein the partially cut band of susceptor material may be cut completely at the precut positions into individual susceptor elements. These individual susceptor elements subsequently may be incorporated into aerosol-forming substrate. This may produce a continuous substrate section comprising the individual susceptor elements. This method also enables an easy cutting of continuous substrate section since the cutting tool only may have to cut the aerosol forming substrate of the substrate section located between the individual susceptor elements. This method of the invention may not cut through susceptor material.
- Individual susceptor elements produced by completely cutting the partially cut band of susceptor material may have a susceptor element length being smaller than the substrate section length of the finished individual substrate sections.
- the susceptor element length may be around 5 percent, or around 10 percent smaller than the substrate section length. This may enable positioning individual susceptor elements within the aerosol-forming substrate of the substrate section without any susceptor material being present at the end faces of the individual substrate sections. The individual susceptor elements therefore may be centrally positioned within the aerosol-forming substrate of the substrate section.
- the method may further comprise increasing a gap between adjacent susceptor elements. This may be done by transporting the individual susceptor elements on an accelerating belt.
- the partially cut band of susceptor material may be transported on a first belt and the individual susceptor elements may be transported on an accelerating belt as a second belt.
- the velocity of the second belt may be higher than the velocity of the first belt.
- the velocity of the second belt may be between 10 percent and 30 percent, preferably 20 percent higher than the velocity of the first belt. This may increase the gaps between individual adjacent susceptor elements.
- gaps between individual adjacent susceptor elements are increased, it may be easier to produce the individual substrate sections by cutting through the gaps of the individual adjacent susceptor elements after they have been integrated into a continuous substrate section.
- the positioning of the cutting tool relative to the continuous substrate section for cutting through the gaps may not be so critical. In the case of some misalignments between the later complete cut in method step C) to produce individual substrate sections and the final cut of the continuous substrate section larger gaps between the individual adjacent susceptor elements within the continuous substrate section may still enable a reliable cutting of the continuous substrate section through the gaps.
- Partially cutting in method step B) may comprise one or more of: producing perforations in the continuous band of susceptor material, producing incisions at one or both edges of the continuous band of susceptor material, or producing a plurality of recesses in the band of susceptor material.

- the continuous substrate portion may be overwrapped with wrapping material, preferably paper.
- Providing the wrapping material around the continuous substrate section may produce a rod-shaped continuous substrate section, wherein the wrapping material stabilizes the substrate section.
- the continuous substrate section may either contain a continuous partially cut band of susceptor material or individual susceptor elements, which may be spaced apart within the continuous substrate section.
- one of the partially cut continuous band of susceptor material or the individual susceptor elements may be transported through a funnel shaped guide element.
- the guide element may be configured for positioning the aerosol-forming substrate around the one of the partially cut continuous band or the individual susceptor elements.
- the funnel shaped guide element may be configured for compressing aerosol-forming substrate around one of the partially cut continuous band of susceptor material or the individual susceptor elements. This may produce a continuous substrate section, which either may comprise the partially cut continuous band of susceptor material or the individual susceptor elements.
- one of the partially cut continuous band of susceptor material or the individual susceptor elements may be transported on a transport device.
- the transport device may comprise a belt, preferably a toothed belt, more preferably a U-shaped toothed belt.
- Such a belt preferably the toothed belt may be particularly well suited in order to transport either the partially cut continuous band of susceptor material or the individual susceptor elements.
- These special belts also may be particularly well configured for transporting the continuous substrate section after the band of susceptor material or the individual susceptor elements have been incorporated into the aerosol-forming substrate.
- the toothed belt may include U-shaped grooves which may run parallel to the transport direction of the toothed belt. These U-shaped grooves may be configured to accommodate the continuous substrate section, in particular a rod-shaped continuous substrate section.
- the toothed belt may be produced from flexible polymers, such as rubber or other flexible polymers such as nylon or aramid-fibers.
- the continuous band of susceptor material may be guided through at least one rotating knife drum or rotating drums with punching tools. This may allow for a partial cutting of the continuous band of susceptor material.
- At least one of the rotating knife drum or rotating drums with punching tools may be able to partially cut the continuous band of susceptor material at a predetermined precut position.
- This predetermined precut position may be at the opposing edges of the band or at predetermined positions on the band.
- a rotating knife drum or rotating drums with punching tools may be located on the opposing edges of the band configured for producing the precuts in the opposing edges of the band of susceptor material.
- These precuts may, as already described above, only cover a small part of the width of the band of susceptor material, for example between a quarter and half of the width.
- the precut may extend along a large part or over the complete length of the width of the band of susceptor material.
- a perforating line may be formed in the continuous band of susceptor material. This may be done by employing rotating drums with punching tools.
- the individual susceptor elements may remain positioned centrally within the individual substrate sections after cutting.
- an individual substrate section may include an individual central longitudinal axis.
- the individual substrate section may be rod-shaped.
- the continuous substrate section may include a continuous central longitudinal axis.
- the individual susceptor elements may be positioned in such a way within the continuous substrate section that the individual susceptor elements are arranged along the continuous central longitudinal axis, preferably wherein the individual susceptor elements may be located in a plane, wherein the continuous central longitudinal axis also runs within that plane.
- individual substrate sections can be produced by completely cutting the continuous substrate section either through the gaps between adjacent individual susceptor elements or at the precuts without applying too much force.
- individual susceptor elements may remain positioned centrally within the individual substrate sections after cutting.
- individual susceptor elements within an individual substrate section may retain their position after cutting. Therefore, and individual susceptor element after cutting may be located in a plane, wherein the individual central longitudinal axis of the substrate section also may run within that plane.
- Individual susceptor elements which are located centrally within the individual substrate sections may easier and more reliably be heated by applying an external alternating electromagnetic field.
- flat regions on opposing edges of the continuous band of susceptor material may be removed as partial cuts. This may create a central linking part connecting different adjacent parts of the partially cut band of susceptor material.
- a detection device may be employed for detection of one of the positions of the precuts on the continuous band of susceptor material or for the position of the gaps between the plurality of individual susceptor elements.
- the detection device may be selected from a group consisting of: x-ray device, induction sensor, infrared camera analyzer, device for measuring impedance.
- These detection devices may be configured to detect the precut positions either on the continuous band of susceptor material incorporated into the continuous substrate section or the gaps between the plurality of individual susceptor elements in the continuous substrate section. Alternatively note detection device may be present. Instead, the main machine drive of a system for producing the aerosol-generating articles may allow for synchronization of the precuts with the final cuts.
- the continuous substrate section may be cut by a rotating blade. This may enable the cutting in order to produce either multiple substrate sections, which may contain for example up to 10 individual substrate sections. Alternatively, the rotating blade may cut the continuous substrate section into individual substrate sections containing individual susceptor elements.
- the continuous band of susceptor material may have an elongate, flat shape.
- the continuous band of susceptor material may comprise a continuous band with opposing edges.

- the individual susceptor elements may have with and may have a length.
- the ratio of the length to the width in the individual susceptor elements may be between 1.5 to 4.5, preferably between 1.8 to 3.5, more preferably between 1.9 to 2.5.
- the length of an individual susceptor element may be between 9 mm to 12 mm and the width may be between 3 mm to 6 mm, preferably the length may be between 10 to 12 mm and the width may be between 4 to 5 mm.
- the length of the substrate section may be between 10 to 15 mm, preferably 12 mm.
- a multiple substrate section containing 10 individual substrate sections therefore may have a length of 120 mm, if one single substrate section has a length of 12 mm.
- the susceptor element comprises or is made of a material that is capable of generating heat, when penetrated by an alternating magnetic field. If the susceptor element is conductive, then typically eddy currents are induced by the alternating magnetic field. If the susceptor element is magnetic, then typically another effect that contributes to the heating is commonly referred to hysteresis losses. Hysteresis losses occur mainly due to the movement of the magnetic domain blocks within the material of the susceptor element, because the magnetic orientation of these will align with the magnetic induction field, which alternates. Another effect contributing to the hysteresis loss is when the magnetic domains will grow or shrink within the material of the susceptor element.
- hysteresis losses are changes in the material of the susceptor element that happen on a nano-scale or below.
- the susceptor is both magnetic and electrically conductive, both hysteresis losses and the generation of eddy currents will contribute to the heating of the susceptor element.
- the material of the susceptor element is magnetic, but not conductive, then hysteresis losses will be the only means by which the susceptor element will heat, when penetrated by an alternating magnetic field.
- the material of the susceptor element may be magnetic and electrically conductive.
- the susceptor material may for example comprise a ferromagnetic material.
- the susceptor material may comprise a ferromagnetic alloy. More preferably the susceptor material may comprise ferritic iron, in particular a ferromagnetic steel or stainless steel.

- the aerosol-forming substrate may comprise a tobacco-containing material containing volatile tobacco flavour compounds which are released from the substrate upon heating.
- the aerosol-forming substrate may comprise a non-tobacco material.
- the aerosol-forming substrate may comprise an aerosol former that facilitates the formation of a dense and stable aerosol.
- Suitable aerosol- formers are well known in the art and include, but are not limited to: polyhydric alcohols, such as triethylene glycol, 1 ,3-butanediol and glycerine; esters of polyhydric alcohols, such as glycerol mono-, di- or triacetate; and aliphatic esters of mono-, di- or polycarboxylic acids, such as dimethyl dodecanedioate and dimethyl tetra-'decanedioate.

- eddy currents induced in the susceptor element by the inductive coil also depend on the shape of the susceptor element and its position relative to the heating element of the aerosol-generating device. Therefore, producing an aerosol-generating article including a susceptor element with a uniform shape and position within the substrate section may greatly enhance the efficiency of the inductive heating.
