## Abstract

A heatable aerosol-generating article for producing an inhalable aerosol is provided, the article including: a rod of aerosol-generating substrate including from about 20 to about 200 strands of non-tobacco material including and configured to release at least one aerosol former, each strand having an equivalent diameter of at least about 0.1 millimetre, the strands being assembled such that the strands extend in a longitudinal direction; and a wrapper circumscribing the strands. A method of making a rod for an aerosol-generating substrate in an aerosol-generating article, and a rod for an aerosol-generating substrate in an aerosol-generating article, are also provided.

## Claims

### Claim 1

A heatable aerosol-generating article for producing an inhalable aerosol, the heatable aerosol-generating article comprising a rod of aerosol-generating substrate, wherein the rod of aerosol-generating substrate comprises:
a plurality of strips of non-tobacco material assembled to form a rod, the strips of non-tobacco material comprising and configured to release at least one aerosol former, the aerosol former being provided as a gel, each strip having an equivalent diameter of at least about 0.1 millimetre, wherein the strips are assembled such that the strips extend in a longitudinal direction and a wrapper circumscribing the strips.

### Claim 2 (depends on 1)

The heatable aerosol-generating article according to claim 1, wherein the aerosol former is provided as a gel composition further comprising nicotine or a flavourant or both.

### Claim 3 (depends on 1)

The heatable aerosol-generating article according to claim 1, wherein each strip of non-tobacco material has an equivalent diameter of less than about 1 millimetre.

### Claim 4 (depends on 1)

The heatable aerosol-generating article according to claim 1, wherein each strip of non-tobacco material has a length between about 5 millimetres and about 80 millimetres.

### Claim 5 (depends on 1)

The heatable aerosol-generating article according to claim 1, wherein each strip of non-tobacco material has an equivalent diameter of less than about 0.5 millimetre.

### Claim 6 (depends on 1)

The heatable aerosol-generating article according to claim 1, wherein each strip of non-tobacco material has a length between about 7 millimetres and about 40 millimetres.

### Claim 7 (depends on 1)

The heatable aerosol-generating article according to claim 1, wherein each strip of non-tobacco material has a length between about 8 millimetres and about 28 millimetres.

### Claim 8 (depends on 1)

The heatable aerosol-generating article according claim 1, wherein the rod comprises less than about 200 strips of the non-tobacco material.

### Claim 9 (depends on 1)

The heatable aerosol-generating article according claim 1, wherein the rod comprises at least about 20 strips of the non-tobacco material.

### Claim 10

A method of making a rod for an aerosol-generating substrate in an aerosol-generating article, the method comprising the steps of:
providing a plurality of strips of non-tobacco material configured to hold and to release an aerosol former, the aerosol former being provided as a gel, each strip having an equivalent diameter of at least about 0.1 millimetre;
assembling the plurality of strips such that the assembled strips extend in a longitudinal direction;
circumscribing the assembled strips with a wrapper to form a continuous rod; and
severing the continuous rod into a plurality of discrete rods.

### Claim 11

A rod for an aerosol-generating substrate in an aerosol-generating article, the rod comprising:
a plurality of strips of non-tobacco material, the strips of non-tobacco material comprising and configured to release at least one aerosol former, the aerosol former being provided as a gel, each strip having an equivalent diameter of at least about 0.1 millimetre, wherein the strips are assembled such that the strips extend in a longitudinal direction; and
a wrapper circumscribing the strips.
