1. A process for producing a roller of high stiffness for a rotary production machine, comprising: producing a first inner tube (10) of a first material;placing intermediate members (12) on said produced first inner tube with a regular spacing, said intermediate members being solid in cross-section
1. A process for producing a roller of high stiffness for a rotary production machine, comprising: producing a first inner tube (10) of a first material;placing intermediate members (12) on said produced first inner tube with a regular spacing, said intermediate members being solid in cross-section and obtained by pultrusion, said members being made of a composite material based on carbon fibers; andproducing at least one second tube (14) of a second material, disposed about the intermediate members, thereby forming a cylindrical roller of a rotary production machine,wherein one of the first and second tubes is made by filamentary winding and an other of the first and second tubes is obtained by pultrusion. 2. The process according to claim 1, wherein one of a resin and a mixture of resins is introduced between the two tubes (10, 14) to embed the intermediate members, fill interstices between the intermediate members, and also ensure connection of the two tubes in rotation. 3. The process according to claim 2, wherein the composite material is used for at least one of the tubes and for the intermediate members, the composite material based on carbon fibers of very high modulus of elasticity and obtained by pultrusion. 4. The process according to claim 2, wherein the intermediate members are obtained from flat profiles made of carbon fibers of very high modulus of elasticity obtained by pultrusion and cut off. 5. The process according to claim 2, wherein the intermediate members are shaped to produce sectors. 6. The process according to claim 1, wherein the composite material is used for at least one of the tubes and for the intermediate members, the composite material based on carbon fibers of very high modulus of elasticity. 7. The process according to claim 6, wherein the intermediate members are obtained from flat profiles made of carbon fibers of very high modulus of elasticity obtained by pultrusion and cut off. 8. The process according to claim 6, wherein the intermediate members are shaped to produce sectors. 9. The process according to claim 1, wherein the intermediate members are obtained from flat profiles made of carbon fibers of very high modulus of elasticity obtained by pultrusion and cut off. 10. The process according to claim 9, wherein the intermediate members are shaped to produce sectors. 11. The process according to claim 1, wherein the intermediate members are shaped to produce sectors. 12. The process according to claim 1, wherein each of the intermediate members (12) have a first side with a first width and a second side, opposite said first side, with a second width, said second width being greater than said first width. 13. The process according to claim 12, wherein the first sides of the intermediate members (12) are disposed on the first inner tube (10), and the second sides of the intermediate members (12) are disposed on the second tube (14). 14. The process according to claim 1, wherein said placing step is performed after said producing step produces said first inner tube (10). 15. The process according to claim 1, wherein said intermediate members (12) are unidirectional and are placed along the longitudinal axis of the first inner tube (10). 16. The process according to claim 1, wherein said intermediate members (12) are placed in a manner as to be parallel to each other and to each extend in a direction along the longitudinal axis of said first inner tube (10) at least over a length of said first inner tube (10). 17. The process according to claim 1, wherein the production machine is a printing machine. 18. A process for producing a roller of high stiffness for a rotary production machine, comprising: producing a first inner tube (10) of a first material;placing intermediate members (12) on said produced first inner tube with a regular spacing, said intermediate members being solid in cross-section and made of a composite material based on carbon fibers; andproducing at least one second tube (14) of a second material, disposed about the intermediate members, thereby forming a cylindrical roller of a rotary production machine,wherein at least one of the first and second tubes is made by filamentary winding. 19. The process according to claim 18, wherein the production machine is a printing machine. 20. A process for producing a roller of high stiffness for a printing machine, comprising: producing a first inner tube (10) of a first material;placing intermediate members (12) on said produced first inner tube with a regular spacing, said intermediate members being solid in cross-section and made of a composite material based on carbon fibers; andproducing at least one second tube (14) of a second material, disposed about the intermediate members, thereby forming a cylindrical roller of a printing machine,wherein at least one of the first and second tubes is made by filamentary winding.
