    摘要： 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.

    摘要翻译： 通过在模腔中填充诸如条子之类的庞大的带状非织造纤维网，然后将如此形成的模制形式热处理成熔接的纤维交叉点来制造成型的缓冲制品。 带状非织造纤维网的填充通过在可透空气的模具的模制表面上以往复运动放置和叠加来实现，空气在模制表面的后侧保持减压。 所使用的装置具有（a）用于将带状非织造纤维网进料到模具中的装置，（b）可渗透空气的模具，（c）模具支撑框架，（d）用于将后侧空间保持在下降的抽吸装置 （e）用于连续地改变装置（a）和成型表面之间的位置相关性的装置，和（f）用于待融合的纤维的热处理装置。

    摘要： A cushioning material for mattresses is formed by needling a pile of crimped fibers to form a flat board, and then continuously and alternately bending the flat board to form a corrugated web. The corrugated web thus formed has a number of side-by-side contact portions and a number of bent portions connecting the side-by-side contact portions. The bent portions thus form a relatively soft surface portion of the cushioning material, and the side-by-side contact portions provide a moderately rigid portion of the cushioning material. The corrugated web may be held together by sewing, bonding or welding.
