Abstract

A rotating drum for use in manufacturing vapor-generating articles may include a drum body. A plurality of grooves may be disposed in an outer face of the drum body. A seat may be tractably-mounted in each one of the plurality of grooves. The seat may include a seat groove that is structured and arranged to receive and hold a rigid casing of a vapor-generating article. The seat may be composed of a material that is softer than a material of the rigid casing.

First claim

The invention claimed is:

1. A rotatable drum for automated manufacturing of e-vapor devices, comprising:
a drum body defining a plurality of pockets and configured to rotate during the automated manufacturing of the e-vapor devices;
a first seat structure configured as a first retractable part in each of the plurality of pockets of the drum body, the first seat structure configured to receive a first section of the e-vapor devices and to hold the first section of the e-vapor devices via a vacuum applied therethrough; and
a second seat structure configured as a second retractable part in each of the plurality of pockets of the drum body, the second seat structure configured to receive a second section of the e-vapor devices and to hold the second section of the e-vapor device via the vacuum applied therethrough, the second seat structure and the first seat structure separated by a channel.

2. The rotatable drum of claim 1 , wherein the plurality of pockets are external pockets in the drum body.

3. The rotatable drum of claim 1 , wherein the plurality of pockets are arranged circumferentially around the drum body.

4. The rotatable drum of claim 1 , wherein the plurality of pockets are oriented in a same direction.

5. The rotatable drum of claim 1 , wherein the plurality of pockets extend in parallel.

6. The rotatable drum of claim 1 , wherein the first seat structure is configured to move radially relative to the drum body.

7. The rotatable drum of claim 1 , wherein the first seat structure defines a groove configured to receive the first section of the e-vapor devices.

8. The rotatable drum of claim 1 , wherein the first seat structure is configured to permit a retraction into the drum body while maintaining the vacuum applied to the first section of the e-vapor devices.

9. The rotatable drum of claim 1 , wherein the first seat structure defines a hole configured to permit the vacuum to be applied therethrough.

10. The rotatable drum of claim 9 , further comprising:
a hollow post connected to the first seat structure via the hole.

11. The rotatable drum of claim 10 , wherein the hollow post is configured as a passageway through which the vacuum is applied.

12. The rotatable drum of claim 10 , wherein the hollow post is a mobile component configured to move with the first seat structure.

13. The rotatable drum of claim 1 , further comprising:
a resilient element disposed between the first seat structure and a corresponding one of the plurality of pockets, the first seat structure being moveable along a radial direction of the drum body via the resilient element, the resilient element configured to bias the first seat structure outward from the drum body along the radial direction.

14. The rotatable drum of claim 1 , further comprising:
a pusher structure moveably arranged in each of the plurality of pockets, the pusher structure configured to apply a lateral force to a side of the first section in the first seat structure.

15. The rotatable drum of claim 14 , further comprising:
a spring oriented longitudinally in each of the plurality of pockets, the spring configured to bias the pusher structure toward the first seat structure.

16. The rotatable drum of claim 1 , further comprising:
a stop structure in the channel between the first seat structure and the second seat structure;
a first pusher structure moveably arranged in each of the plurality of pockets, the first seat structure being between the first pusher structure and the stop structure; and
a second pusher structure moveably arranged in each of the plurality of pockets, the second seat structure being between the stop structure and the second pusher structure.

17. The rotatable drum of claim 16 , wherein:
the first pusher structure is configured to apply a lateral force to a side of the first section in the first seat structure so as to push the first section against the stop structure; and
the second pusher structure is configured to apply a lateral force to a side of the second section in the second seat structure so as to push the second section against the stop structure.
