Abstract

A hollow, rigid window covering component for use as a slat or otherwise, generally used as an alternative to wood, the component being filled with a foam using a substantially continuous manufacturing process. The apparatus used for this process comprises a die having a substantially toroid-shaped resin chamber and a channel or void through which to inject a core material into the enclosed perimeter of the hollow window covering component.

Description

RELATED APPLICATIONS [0001] This application claims priority to U.S. provisional application Ser. No. 60 / 570,240, filed May 12, 2004.BACKGROUND [0002] 1. Field of the Invention [0003] The present invention relates generally to coverings for windows or for other similar openings. More particularly, the present invention relates to window covering parts and methods and apparatus for making the same. [0004] 2. Background Information [0005] Window coverings such as shutters or blinds are often used to cover windows and other similar openings to provide privacy or to control the level of light that enters a room. A blind, sometimes called a “Venetian” blind, is a popular type of window covering and comprises a series of spaced-apart slats or louvers assembled parallel to each other. In some cases, the slats are disposed horizontally with respect to the window; in others, the slats are disposed vertically. [0006] In recent years, blinds made of wooden slats have gained popular appeal. Sin...
