Abstract
A filter part () for use in an aerosol generating article and a method of manufacturing the filter part (). The filter part () includes an aerosol permeable core () surrounded by a sleeve (). The sleeve () is formed of linear, axially oriented fibres and the core () is formed of expanded, randomly oriented fibres. The method includes forming two or more strips () into segments surrounding a conveying path, bringing the segments together into a sleeve former () to form the sleeve () and introducing loose fibres () between the segments upstream of the sleeve former () such that they are drawn therein in a random orientation and compressed between the segments as they are brought together to form a filter rod () with an aerosol permeable core () within the sleeve (). The filter rod () is then cut to form the filter part ().
