Abstract
An inventive machine and method are used for manufacturing fiber articles with a variable density across the article. The machine includes a mold providing a cavity. An inventive cover providing an opening is arranged over the cavity. In one example, the opening is provided on a belt. The size of the opening may also be adjustable. The cover and mold move relative to one another to arrange the opening over multiple portions of the cavity. A fiber feed system deposits fiber material in the multiple portions beneath the opening in varying amounts. Various sensors and other devices may be used to control the positioning of the opening to regulate the distribution of fiber deposited in the cavity.
