Title:
【発明の名称】繊維集合体の型詰め方法、成型クッション体の製造方法、およびそれらのための装置
Document Type and Number:
Japanese Patent JP2960820
Kind Code:
B2
Abstract:
A molded cushioning article is made by stuffing a bulky, tape-form nonwoven web such as sliver in a mold cavity and thereafter heat-treating the thus-formed molded form to fusion-bond intersecting points of fibers. Stuffing of the tape-form nonwoven web is effected by laying and superposing it in to-and-fro movements on a molding surface of a mold permeable to air with a space on a backside of the molding surface being kept under reduced pressure. The apparatus used has (a) means for feeding the tape-form nonwoven web into the mold, (b) a mold permeable to air, (c) a mold-supporting frame, (d) suction means for keeping the backside space under reduced pressure, (e) means for successively changing a positional correlation between means (a) and the molding surface, and (f) heat-treating means for fibers to be fusion-bonded.
