Description

Composite aerosol-generating material The application is a divisional application of Chinese patent application with International application number PCT/EP2020/075903, chinese application number 202080061703.9, application date 2020, month and 16, named as "composite aerosol generating Material". Technical Field The present disclosure relates to a composite aerosol-generating material, a method of manufacturing such a composite aerosol-generating material and an apparatus for such manufacturing. In addition, the present disclosure relates to aerosol-generating rods comprising composite aerosol-generating material, manufacturing methods of manufacturing such rods, and apparatuses for manufacturing such rods. The aerosol-generating rod may be used in an aerosol-generating article. The aerosol-generating article may be used with an aerosol-generating device. The present disclosure relates particularly, but not exclusively, to applying a gel in a sandwich configuration between aerosol generating materials or carrier materials. Preferably, the gel comprises an active agent, such as a fragrance, a humectant, a plasticizer or nicotine. Preferably, the gel comprises a combination of active agents. Background In order to manufacture an aerosol-generating rod, the procedure generally involves the following steps. A flat sheet of aerosol-generating material is unwound from a bobbin of aerosol-generating material. The aerosol-generating material is then typically sprayed with a liquid or powder component, such as glycerin or a fragrance. Finally, the aerosol-generating material is drawn into a funnel-shaped device which aggregates the sheets into a continuous cylindrical rod of the desired diameter. The continuous rod is wrapped and cut to a desired length before being combined with other rods in a line to form an aerosol-generating article. However, spraying liquid or powder components onto the sheet may lead to certain drawbacks. For example, during spraying, typically only a portion of the material is sprayed and secured to the sheet of aerosol-generating material. It is therefore desirable to provide an improved application of fragrances and other components that overcomes these disadvantages. It is also desirable to provide an aerosol-generating material for use in an aerosol-generating rod, and to provide an apparatus and method of manufacturing an aerosol-generating material that will reduce the amount of wasted components, so that manufacturing costs may also be reduced and that will require less cleaning, thereby saving time. Disclosure of Invention According to one aspect of the present invention there is provided a method of manufacturing a composite aerosol-generating material, the method comprising the steps of: -providing a first continuous sheet of carrier material; -dispensing a gel onto the surface of the first continuous sheet of carrier material; Providing a second continuous sheet of carrier material and positioning the second continuous sheet of carrier material to the gel to form a composite material, wherein gel is interposed between the first continuous sheet of carrier material and the second continuous sheet of carrier material, and -Further comprising the step of dispensing a larger amount of gel to a central region of the first continuous carrier material sheet proximal to the longitudinal axis of the first continuous carrier material sheet relative to the amount of gel dispensed to a lateral region distal to the longitudinal axis of the first continuous carrier material sheet.
