Abstract

The present invention provides a method and apparatus for manufacturing smoking articles. First multi-segment components are formed each comprising a combustible heat source, an aerosol-forming substrate and an airflow directing segment by feeding a stream of combustible heat sources, aerosol-forming substrates and airflow directing segments along a moving delivery path, compacting the segments into groups; wrapping each group; and cutting the web of material between groups to separate the individual first multi-segment components from each other. A stream of first multi-segment components are fed onto a receiving means, and a stream of second multi-segment components, each comprising a mouthpiece and at least one further segment, are also fed onto the receiving means. A first multi-segment component and a second multi-segment component are combined by wrapping the components in a web material to form an individual smoking article having a combustible heat source at a first end and a mouthpiece at a second end.

First claim

The invention claimed is:

1. A method of manufacturing smoking articles, comprising:
forming first multi-segment components each comprising a combustible heat source, an aerosol-forming substrate and an airflow directing segment by:
feeding a stream of combustible heat sources, aerosol-forming substrates and airflow directing segments along a moving delivery path, wherein at least one segment of the first multi-segment component is cut on-line;
compacting into groups the combustible heat sources, the aerosol-forming substrates and the airflow directing segments, each group corresponding to a discrete first multi-segment component;
wrapping the combustible heat sources, aerosol-forming substrates, and airflow directing segments in a web of material; and
cutting the web of material between groups to separate the individual first multi-segment components from each other;

feeding a stream of first multi-segment components onto a receiving means;
feeding a stream of second multi-segment components, each comprising a mouthpiece and at least one further segment, onto the receiving means; and
combining a first multi-segment component and a second multi-segment component by wrapping the first multi-segment component and the second multi-segment component in a web material to form an individual smoking article having a combustible heat source at a first end and a mouthpiece at a second end.

2. The method according to claim 1 , wherein the segments on the moving delivery path have their longitudinal axes substantially aligned with each other and with a direction of movement of the moving delivery path.

3. The method according to claim 1 , wherein, in compacting into groups the combustible heat sources, the aerosol-forming substrates and the airflow directing segments, there is a predefined space between a leading group of segments and a trailing group of segments.

4. The method according to claim 1 , wherein individual combustible heat sources are fed from a hopper.

5. The method according to claim 1 , wherein the combining step further includes:
receiving sets of discrete first multi-segment components, each set of discrete first multi-segment components comprising two first multi-segment components;
separating, along a longitudinal axis of the first multi-segment components, the first multi-segment components in each set of discrete first multi-segment components;
receiving, between the separated first multi-segment components, a set of discrete second multi-segment components, each set of discrete second multi-segment components comprising two second multi-segment components joined such that the mouthpieces of each second multi-segment component are adjacent each other;
aligning the longitudinal axes of the first and second multi-segment components on a combining drum;
compacting the first and second multi-segment components into a group;
wrapping the group in the web material to form a double smoking article; and
cutting the double smoking article between the mouthpieces of the two second multi-segment components to form individual smoking articles.

6. The method according to claim 1 , wherein, during the step of combining the first multi-segment component and the second multi-segment component, the first multi-segment component is further wrapped with a heat conducting element comprising one or more layers of a heat-reflective material.

7. The method according to claim 1 , wherein the first multi-segment component further comprises an expansion chamber.

8. The method according to claim 7 , wherein the at least one further segment of the second multi-segment component further comprises a filter segment.
