Abstract

The present disclosure relates to a drum (18) for a tobacco industry product manufacturing apparatus. The drum (18) comprises an axis (19) about which it rotates and a seat (23) adapted to carry components of tobacco industry products during use. The seat (23) is movable in a direction towards the axis (19) of the drum (18) in response to said components being pressed against the seat during use.

First claim

1 . A drum for a tobacco industry product manufacturing apparatus, the drum comprising an axis about which the drum rotates and a seat adapted to carry components of tobacco industry products during use, wherein the seat is movable in a direction towards the axis of the drum in response to said components being pressed against the seat during use.

2 . A drum according to claim 1 , wherein the seat comprises a plate adapted to deflect inwards towards the axis of the drum in response to said components being pressed against the plate during use.

3 . A drum according to claim 2 , wherein the plate is pivotally mounted to a pivot so that the plate is deflected about the pivot in a direction towards the axis of the drum in response to said components being pressed against the plate during use.

4 . A drum according to claim 2 , wherein the plate is slidably mounted so that the plate slides in a direction towards the axis of the drum in response to said components being pressed against the plate during use.

5 . A drum according to any of claims 2 to 4 , wherein the drum further comprises a biasing member arranged to bias the plate in a direction away from the axis of the drum.

6 . A drum according to claim 5 , wherein the biasing member is a spring.

7 . A drum according to claim 1 , wherein the seat is resiliently deformable such that the seat deforms in response to said components being pressed against the seat during use.

8 . A drum according to any preceding claim, wherein the drum comprises a circumferential surface and the seat is arranged on the circumferential surface of the drum.

9 . A drum according to claim 8 , wherein the seat extends only partially across the circumferential surface of the drum in a direction parallel with the axis of the drum such that said components of tobacco industry products on the drum at least partially overlie the seat during use.

10 . A drum according to claim 8 , wherein the seat extends across the circumferential surface of the drum in a direction parallel with the axis of the drum such that the full length of each component is carried on the seat.

11 . A drum according to any of claims 8 to 10 , wherein the drum comprises a second seat that is aligned to the seat in the axial direction on the circumferential surface of the drum.

12 . A drum according to claim 11 , wherein the seat and the second seat are spaced from each other in a direction parallel with the axis of the drum.

13 . A drum according to claim any preceding claim, wherein the seat comprises a surface having suction holes adapted to retain said components on said surface when suction is applied to the at least one suction hole during use.

14 . A drum according to claim 13 , wherein the suction holes are arranged to retain a paper patch.

15 . A drum according to any preceding claim, wherein the seat comprises a flute adapted to receive elongate components of tobacco industry products.

16 . A drum according to claim 15 , wherein the flute comprises at least one suction hole adapted to retain said elongate components when suction is applied to the at least one suction hole during use.

17 . A drum according to any preceding claim, wherein a peripheral surface of the seat is substantially level with a circumferential surface of the drum when said components are not pressed against the seat.

18 . A drum according to any preceding claim, wherein the drum is a transfer drum adapted to receive a paper patch in a first position and transfer said paper patch to a further drum in a second position during use, wherein the further drum is adapted to carry a collation of components and to receive a paper patch from the transfer drum during use.

19 . A drum according to any of claims 1 to 17 , wherein the drum is a rolling drum adapted to receive a collation of components including elongate components and a paper patch and to carry said collation of components through a rolling mechanism to roll the paper patch about the elongate components to form tobacco industry products during use, and to transfer said tobacco industry products to a further drum during use.

20 . A drum according to any of claims 1 to 17 , wherein the drum is a transfer drum adapted to receive components of tobacco industry products and to transfer said components to a further drum during use.

21 . A drum according to any of claims 1 to 17 , wherein the drum is a transfer drum adapted to receive a collation of cylindrical components and paper patches and to transfer said components and paper patches to a further drum during use.

22 . Apparatus for manufacturing tobacco industry products, the apparatus comprising a drum according to any of claims 1 to 21 .

23 . A drum for a tobacco industry product manufacturing apparatus substantially as described with reference to the accompanying figures.

24 . Apparatus for manufacturing tobacco industry products substantially as described with reference to the accompanying figures.
