Abstract

The present invention is an artificial tree consisting of a shape such as conical wherein there is an artificial outer layer, e.g. artificial grass, a solidified foam core, and a post molded into the foam core.

Claims

1. A method of making an artificial tree comprising:

a) cutting and joining a woven outer layer into a predetermined shape;

b) placing a cut and joined woven outer layer inside a tube or post sufficiently strong to hold the tree upright;

c) adding uncured foam designed for solidification expansion to an inside of the woven outer layer;

d) positioning the post or tube centered in the uncured foam and holding it in place;

e) curing the uncured foam to create a solidified expanded foam core with the post or tube sticking out a bottom; and

f) removing the artificial tree from the mold.

2. The method of making the artificial tree according to claim 1 wherein a piece of woven outer layer material is positioned on a top of the solidified expanded foam core.

3. The method of making the artificial tree according to claim 1 wherein the post or tube is positioned using a jig which holds the rigid post or tube in place during curing of the foam.
