Abstract

A tipping paper feed assembly (1) for use in smoking article manufacture. The tipping paper feed assembly (1) comprising a first feed device adapted to supply a first tipping paper web (4) that is fed into apparatus for smoking article manufacture, and a second feed device adapted to supply a second tipping paper web (11). The tipping paper feed assembly (1) also comprises a splice mechanism (12) adapted to attach the first and second tipping paper webs (4, 11) together for changeover between the first and the second feed devices. The tipping paper feed device (1) also comprises a registration system configured to register features of each tipping paper web (4, 11) prior to attaching said first and second tipping paper webs together with said features in register.

First claim

The invention claimed is:

1. A tipping paper feed assembly for use in smoking article manufacture, the tipping paper feed assembly comprising:
a first feed device adapted to supply a first tipping paper web that is fed into apparatus for smoking article manufacture;
a second feed device adapted to supply a second tipping paper web;
a splice mechanism adapted to attach the first and second tipping paper webs together for changeover between the first and the second feed devices, the splice mechanism being configured to move the first tipping paper web towards the second tipping paper web and including a tape holder that holds adhesive tape to attach the first and second tipping paper webs together as said first tipping paper web moves towards the second tipping paper web; and,
a registration system configured to register features of each tipping paper web prior to attaching said first and second tipping paper webs together with said features in register,
wherein the splice mechanism comprises a first cutter adapted to cut the first tipping paper web, said first cutter being mounted on the tape holder so that said first tipping paper web is cut as the first tipping paper web is moved towards the second paper web and the first and second tipping paper webs are attached to each other with said adhesive tape.

2. The tipping paper feed assembly of claim 1 , further comprising an accelerating roller configured to accelerate the second tipping paper web prior to the splice mechanism attaching the first and second tipping paper webs together.

3. The tipping paper feed assembly of claim 2 , wherein the accelerating roller is configured to accelerate the second tipping paper web until the speed of the second tipping paper web substantially matches the speed of the first tipping paper web.

4. The tipping paper feed assembly of claim 2 , further comprising a reservoir into which the second tipping paper web is directed prior to the splice mechanism attaching the first and second tipping paper webs together.

5. The tipping paper feed assembly of claim 1 , wherein the registration system comprises a first sensor arranged to detect a feature of the first tipping paper web.

6. The tipping paper feed assembly of claim 5 , wherein the registration system comprises a second sensor arranged to detect a feature of the second tipping paper web.

7. The tipping paper feed assembly of claim 6 , wherein at least one of the first and second sensors is configured to detect a printed mark.

8. The tipping paper feed assembly of claim 6 , wherein at least one of the first and second sensors is configured to detect an edge.

9. The tipping paper feed assembly of claim 6 , wherein the first sensor is disposed to detect the first web of tipping paper downstream of the splice mechanism.

10. The tipping paper feed assembly of claim 6 , wherein the second sensor is disposed to detect the second web of tipping paper downstream of the splice mechanism.

11. The tipping paper feed assembly of claim 1 , wherein the splice mechanism further comprises a second cutter adapted to cut off excess material from the second tipping paper web during changeover from the first feed device to the second device.

12. Apparatus for smoking article manufacture comprising the tipping paper feed assembly of claim 1 .

13. A method of assembling smoking articles comprising:
feeding a first tipping paper web from a first feed device to a tipping unit adapted to assemble smoking articles;
attaching first and second tipping paper webs together for changeover from the first feed device to a second feed device that feeds said second tipping paper web by moving the first tipping paper web towards the second tipping paper web so that adhesive tape held by a tape holder attaches said first and second tipping paper webs together;
registering a feature of each tipping paper web prior to attaching the said first and second tipping paper webs together in register, and
cutting the first tipping paper web using a first cutter mounted on the tape holder so that the first tipping paper web is cut as the first tipping paper web is moved towards the second tipping paper web and the first and second tipping paper webs are attached to each other with said adhesive tape.

14. The method of claim 13 , further comprising accelerating the second tipping paper web prior to attaching the first and second tipping paper webs together.

15. A tipping paper feed assembly for use in smoking article manufacture, the tipping paper feed assembly comprising:
a first feed device adapted to supply a first tipping paper web that is fed into apparatus for smoking article manufacture;
a second feed device adapted to supply a second tipping paper web;
a splice mechanism adapted to attach the first and second tipping paper webs together for changeover between the first and the second feed devices; and,
a registration system configured to register features of each tipping paper web prior to attaching said first and second tipping paper webs together with said features in register,
wherein the registration system comprises a first sensor arranged to detect a feature of the first tipping paper web, and a second sensor arranged to detect a feature of the second tipping paper web,
wherein at least one of the first and second sensors is configured to detect a cut line.
