Abstract

A method is provided for the production of structural cylinder with a wound material shell, the method comprising: providing a extruded wood core cylinder; wrapping a flexible material about an exterior surface of the cylinder; applying an adhesive between the interior of the material and the exterior profile of the core; allowing the adhesive to cure providing a structural cylinder with a wrapped material exterior.

Claims (11)

1. A method for the production of structural winding support cylinder with a wound material shell, the method comprising:

providing a extruded wood fiber core cylinder, said extruded wood fiber core cylinder consisting of wood fiber and a thermoset resin, said thermoset resin being distributed uniformly throughout said wood fiber;

wrapping a flexible material about an exterior surface of said cylinder said material consisting of paper tape such that said tape is positioned so that its edges are contiguous;

applying an adhesive between an interior surface of said flexible material and said exterior surface of said cylinder;

allowing said adhesive to cure providing a load bearing structural cylinder with a wrapped material exterior shell about which other flexible materials may be wrapped for transportation and storage of said other flexible materials.

2. The method according to claim 1 wherein said flexible material is a sheet of flexible material.

3. The method according to claim 1 further comprising application of a plurality of layers of said material.

4. The method according to claim 1 wherein said flexible material is preferentially applied to parts of said extruded wood core cylinder such that said structural cylinder has a non-cylindrical profile exterior.

5. The method according to claim 4 wherein said profile exterior comprises a parabolic frustrum.

6. The method according to claim 1 further comprising applying a finish layer.

7. The method of claim 1 wherein said adhesive is selected from the group of adhesives consisting of glues and gums.
