Reinforced wood fiber core and method of making thereof
A winding core with improved beam and hoop strength and diminished friability and method for manufacturing such a core are provided, the method for making the winding core comprising: providing a wood fiber core, applying an adhesive to the wood fiber core, and sliding a tube or sheath onto the wood fiber core.
1. A method for manufacturing a winding core, said method comprising:
Providing an extruded wood fiber core member having an external diameter;
applying an expanding adhesive to said extruded wood fiber core member;
sliding a pre-formed un-split sheath over said extruded wood fiber core member.
2. The method of claim 1 further comprising:
clamping said sheath to said extruded wood fiber core member and allowing said adhesive to cure.
3. The method of claim 1 further comprising:
cutting a longitudinal notch into said wood fiber core member and said sheath.
4. The method of claim 1 further comprising:
affixing end caps and plates to said wood fiber core member and said sheath.
5. The method of claim 4 further comprising:
applying a finish to the exterior surface of said sheath.
6. The method of claim 1 further comprising:
applying a finish to the exterior surface of said sheath.
7. The method of claim 1 wherein said wood fiber core has a square internal bore.
8. The method of claim 1 wherein said extruded wood fiber core has an internal bore having a circular cross section.
9. The method of claim 1 wherein said extruded wood fiber core has an internal bore having a squirkle cross section.
10. The method of claim 1 wherein said sheath is longitudinally uncut.
11. The method of claim 1 further comprising using a mechanical mechanism to force said sheath over said core member.
12. The method of claim 11 wherein said mechanical mechanism is a filament wrapped in a spiral configuration around said core.
13. The method of claim 11 wherein said mechanical mechanism is a ram.
14. The method of claim 11 wherein said mechanical mechanism is pressurized air disposed between said sheath and said core.
