4. The rotatable drum of claim 1 , wherein the resilient element is disposed between the first inner surface of the first seat structure and a base of 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.

5. 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 casing in the first groove of the first seat structure.

6. The rotatable drum of claim 5 , 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.

7. The rotatable drum of claim 1 , further comprising:

a second seat structure tractably-mounted in each of the plurality of pockets of the drum body, the second seat structure including a second outer surface and an opposing second inner surface, the second outer surface defining a second groove therein and facing outward from the drum body, the second groove configured to receive and hold a second casing of the e-vapor devices.

8. The rotatable drum of claim 7 , further comprising:

a stop structure 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.

9. The rotatable drum of claim 8 , wherein:

the first pusher structure is configured to apply a lateral force to a side of the first casing in the first groove of the first seat structure so as to push the first casing against the stop structure; and

the second pusher structure is configured to apply a lateral force to a side of the second casing in the second groove of the second seat structure so as to push the second casing against the stop structure.

10. A system for automated manufacturing of e-vapor devices, comprising:

a rotatable drum including

a drum body including a roll face bounded by opposing end faces, the roll face defining a plurality of pockets therein, and

a seat structure tractably-mounted in each of the plurality of pockets of the drum body, the seat structure including an outer surface and an opposing inner surface, the outer surface defining a groove therein and facing outward from the drum body, the groove configured to receive and hold a casing of the e-vapor devices;

a tagging assembly configured to attach a label to the casing in the groove of the seat structure, the tagging assembly configured to initially attach a central portion of the label to an outer surface of the casing such that a leading edge and a trailing edge of the label do not contact the casing when the label is initially attached to the casing; and

a wrapping assembly configured to wrap the label around the casing.

11. The system of claim 10 , wherein the rotatable drum further includes a resilient element disposed between the inner surface of the seat structure and a base of a corresponding one of the plurality of pockets, the seat structure being moveable along a radial direction of the drum body via the resilient element, the resilient element configured to bias the seat structure outward from the drum body along the radial direction.

12. The system of claim 10 , wherein the tagging assembly is configured to initially attach the central portion of the label to the outer surface of the casing such that the central portion is closer to the leading edge than the trailing edge.

13. The system of claim 10 , wherein the tagging assembly is configured to remove a backing sheet from a continuous web to expose a pressure sensitive adhesive and to cut the label from the continuous web.

14. A method of automated manufacturing of e-vapor devices, comprising:

receiving and holding a casing of the e-vapor devices in a seat structure that is tractably-mounted in a pocket of a rotating drum;

tagging a label to the casing while the casing is held in the seat structure, the tagging including initially attaching a central portion of the label to an outer surface of the casing such that a leading edge and a trailing edge of the label do not contact the casing when the label is initially tagged to the casing; and

wrapping the label around the casing.

15. The method of claim 14 , wherein:

the seat structure is moveable along a radial direction of the rotating drum; and

the seat structure is biased outward from the rotating drum along the radial direction.

16. The method of claim 14 , further comprising:

removing a backing sheet from a continuous web to expose a pressure sensitive adhesive; and

cutting the label from the continuous web prior to the tagging.

17. The method of claim 14 , further comprising:

inserting components corresponding to one of the e-vapor devices in the casing after the wrapping.

18. The rotatable drum of claim 1 , wherein the resilient element is a helical structure wound around the post.

19. The rotatable drum of claim 1 , wherein the post is centrally located within and substantially coaxial with a longitudinal axis of the resilient element.
