ABSTRACT:
A method for fabricating fiber-filled articles in which a single emanating column of continuous synthetic crimped tow is produced, cut and utilized to form the article without conventional processing and treatment. The invention includes the method for fabricating these articles as well as an apparatus for forming fiber-filled articles in which columnar bundles of continuous crimped tow are either wrapped in fabric sleeve tubes or are used independently of sleeves. The continuous crimped tow of synthetic fibers is used as a filler directly as it emanates from the tow processing equipment, without the need for layering, spraying, or pre-cutting between an article's outer material layers. The "modular" independent columns of restrained tow are attached in combination to form filber-filled products such as quilts, c;omforters, and sleeping bags imparting to the apparatus and process the advantages of high production fabrication.
