Abstract

A system, apparatus and method of manufacturing a tubular element (500) for use in an aerosol generating article. The tubular element (500) may comprise gel (124), or comprise a porous medium (125) loaded with gel (124), or comprise thread loaded with gel (214), or comprise a combination thereof.

First claim

The invention claimed is:

1. A tubular element manufacturing system, for manufacturing tubular elements comprising gel; the tubular element manufacturing system comprising:
a first continuous feeder configured to continuously feed a first web of wrapping material along a feed path;
a nozzle configured to dispense gel directly onto the first web of wrapping material;

wherein the gel comprises water;
a second continuous feeder to feed a second component onto the first web of wrapping material after the gel has been dispensed directly onto the first web of wrapping material;
a wrapper configured to wrap the first web of wrapping material around the gel and second component, to form a continuous length of tubular element.

2. The tubular element manufacturing system according to claim 1 in which the second component is a porous medium.

3. The tubular element manufacturing system according to claim 1 , wherein a nozzle is configured to dispense gel onto a second component on the first web of wrapping material.

4. The tubular element manufacturing system according to claim 1 in which the second component is a second web of wrapping material and in which the second continuous feeder further comprises a wrapper configured to wrap the second web of wrapping material to form a second tubular element.

5. The tubular element manufacturing system according to claim 3 in which comprises a third feeder to feed a third component.

6. The tubular element manufacturing system according to claim 5 in which the third feeder feeds the third component onto the first web of wrapping material.

7. The tubular element manufacturing system according to claim 5 in which the third feeder feeds the third component onto the second web of wrapping material.

8. The tubular element manufacturing system according to claim 5 in which the third component is a porous medium.

9. The tubular element manufacturing system according to claim 4 in which a nozzle to dispense gel is adapted to dispense gel directly on the second web of wrapping material.

10. The tubular element manufacturing system according to claim 1 in which the tubular manufacturing system further comprises a cutter configured to cut the continuous length of tubular element into a plurality of discrete tubular elements.
