Abstract

A liquid latex emulsion is compressed to align the randomly arranged molecules to form rows of aligned molecules. A continuous flow of the liquid is created in the direction of the rows of aligned molecules. A first latex layer of rows of aligned latex molecules is created on a form by immersing the form into the continuous flow of compressed liquid at a first immersion angle. A second latex layer is created on the first latex layer, the second latex layer has rows of aligned latex molecules extending in a direction different the rows of aligned latex molecules of the first layer. The second latex layer is formed by immersing the form with the first latex layer into the flow of compressed liquid at an immersion angle different from the first immersion angle.

Claims (5)

1. A method of fabricating a latex product on a form having the shape of the product to be fabricated from a liquid latex emulsion comprising randomly arranged latex molecules, the method comprising the steps of:

(a) compressing the liquid latex emulsion to align the randomly arranged molecules to form rows of aligned molecules;

(b) creating a continuous flow of the compressed liquid in the direction of the rows of aligned molecules;

(c) forming a first latex layer comprising rows of aligned latex molecules on the exterior surface of the form by transporting the continuous flow of the compressed liquid through one or more tubes ending proximate the surface of the form and moving the ends of the one or more tubes and the form relative to each other in a first direction; and

(d) forming a second latex layer on the first latex layer, the second latex layer comprising rows of aligned latex molecules extending in a direction different from the direction of the rows of aligned latex molecules of the first layer, the second latex layer being formed by transporting the continuous flow of the compressed liquid through the one or more tubes ending proximate the surface of the form and moving the ends of the one or more tubes and the form relative to each other in a second direction.
