Abstract

A header assembly for use in a composite roller includes a core having a radially outwardly facing surface. A head is formed around the outwardly facing surface and extends radially from the outwardly facing surface. The head includes a first axially extending face and a second axially extending face facing away from the first axially extending face. In one embodiment, an axially opening channel is formed in the head for receiving at least one balancing weight. In another embodiment, the head is formed from a curable moldable material molded around a metal core.

Claims

1. A header assembly comprising:

a core having a radially outwardly facing surface;

a head formed around said outwardly facing surface and extending radially from said outwardly facing surface, said head including a first axially extending face and a second axially extending face facing away from said first axially extending face; and

an axially opening channel formed in said head for receiving at least one balancing weight.

2. The assembly as in claim 1, in which said head includes an axially extending circumferential lip, and said channel is formed at a junction of said lip and said first axially extending face.

3. The assembly as in claim 1, in which said head is formed from a curable material.

4. The assembly as in claim 1, in which said head is bonded to said core.

5. The assembly as in claim 1, in which said core is selected from a group consisting of an annular ring and a journal.

6. The assembly as in claim 1, in which locking structure formed on said outwardly facing surface of said core locks said head relative to said core.

7. The assembly as in claim 1, including a balancing weight received in said channel and fixed relative to said head.

8. The assembly as in claim 1, including a cover fixed relative to said head covering said channel.

9. A composite roller comprising:

a tubular shaft formed from a composite material and having opposing open ends defining an inner surface; and

at least one composite header assembly received in one end of said opposing ends, said header assembly including a core having a radially outwardly facing surface, a head formed around said outwardly facing surface and fixed relative to said tubular shaft, said head including a first axially extending face facing into said tubular shaft and a second axially extending face facing away from said first axially extending face;

said head including an axially opening channel for receiving at least one balancing weight.

10. The roller as in claim 9, in which said head includes an axially extending circumferential lip, and said channel is formed at a junction of said lip and said first axially extending face.

11. The roller as in claim 9, in which said head is formed from a curable material.

12. The roller as in claim 9, in which said head is bonded to said core.

13. The roller as in claim 9, in which said core is selected from a group consisting of an annular ring and a journal.

14. The roller as in claim 9, in which locking structure formed on said outwardly facing surface of said core locks said head relative to said core.

15. The roller as in claim 9, including a balancing weight received in said channel and fixed relative to said head.

16. The roller as in claim 9, including a cover fixed relative to said head covering said channel.

17. A method of making a composite roller, said method comprising:

pouring a moldable material into a mold to form a head around a core, said mold including an opening closed by said core; and

hardening said moldable material to form the head and fix the head to the core;

inserting said head into one end of a tubular body; and

fixing said head relative to said tubular body to make the roller.

18. The method as in claim 17, including forming a channel in said head

19. The method as in claim 18, including fixing a cover over said channel.

20. The method as in claim 17, including balancing the roller by fixing at least one balancing weight in said channel.

21. The method as in claim 17, in which said core is selected from a group consisting of an annular ring and a journal.

22. The method as in claim 17, in which said moldable material includes a curable resin, and hardening said moldable material includes curing said resin.

23. The method as in claim 22, in which said core is formed from a metal, and curing said resin causes said head to lock onto said core.
