ABSTRACT:
An apparatus for making a fiber batt includes an opening roll for opening fibers fed thereto; a fiber removing device directing an air stream to the opening roll for removing the opened fiber therefrom; a downwardly open fiber gathering hood; an arrangement for introducing into the hood an air stream carrying the opened fiber removed from the opening roll; an air-pervious, continuously moving fiber gathering surface covered by the fiber gathering hood; an arrangement for forcing air from the fiber gathering hood through the fiber gathering surface for depositing the fibers thereon to form a fiber batt; and an arrangement for heating the fibers with a heated air stream in a zone between the opening roll and the fiber gathering surface for effecting a heat treatment of the fibers, such as a binding of the fibers with a binding agent mixed to the fibers.
