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 () within a sleeve () formed integrally therearound. The core () is shorter than the integrally formed sleeve (). The method includes conveying a plurality of aerosol permeable cores () along a conveying path at a first speed (S) and forming a sleeve () around each core () at a second speed (S). The second speed (S) is greater than the first speed (S) to generate a space between consecutive cores () within the sleeve ().

Aerosol generating articles

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 ().

An apparatus for introducing objects into a smoking article comprises a reservoir for providing a plurality of objects to be introduced into the smoking article, a rotatable wheel for delivering the objects to the location where the objects are to be introduced into the smoking article, a transfer chamber for transferring the objects to the rotatable wheel, the transfer chamber being arranged between the reservoir and the rotatable wheel and being designed such that the objects are aligned into a single vertically arranged layer therein, and means for moving the objects from the single layer in the transfer chamber in a direction towards or along the peripheral surface of the rotatable wheel.
