  • Patent number: 9211660
    Abstract: An adjustable support is used to support a preformed mold in a molding operation. The adjustable support includes an aggregate or particulate material that in a now stressed or reduced stress state is flowable to allow shaping thereof to effectively support a back face of the preformed mold. The adjustable support is then jammed to rigidify or fix the shape thereby effectively supporting the preformed mold. The adjustable support is changed from an adjustable state to a support state preferably by applying a vacuum pressure to the aggregate material. In the adjustable state an airflow can be introduced to the aggregate material to allow movement and/or displacement of the material.

  • Patent number: 7910038
    Abstract: A method for making a preform includes creating a pressure differential between an inside and an outside of a perforated shape memory polymer mandrel in its temporary shape. The pressure differential is such that pressure outside the perforated shape memory polymer mandrel is greater than pressure inside the perforated shape memory polymer mandrel. The perforated shape memory polymer mandrel has i) a predetermined preform shape as the temporary shape and ii) a shrunken shape as its permanent shape, wherein the shrunken shape is configured such that it is removable from the predetermined preform shape. The method further includes depositing, as the pressure differential is maintained, at least one material onto a surface of the perforated shape memory polymer mandrel. The at least one material is set in the predetermined preform shape, thereby forming the preform.

  • Patent number: 7745685
    Abstract: A technique for incorporating odor control agent particles into an absorbent article is provided. More specifically, the odor control particles are “homogenously” distributed (e.g., in a substantially uniform manner) within an airformed fiber matrix of an absorbent core of an absorbent article. An absorbent core containing such a homogeneously distributed odor control particles may possess a greater surface area for contacting malodorous compounds, thereby increasing the likelihood of odor reduction.

  • Patent number: 7622062
    Abstract: A method for producing three-dimensional parts made of fiber material using a mold, comprising a bottom mold, the inner side of which determines the contour of the bottom side of the molded part and a top mold whose inner side determines the contour of the top side of the molded part. The bottom mold and/or the top mold have holes enabling the passage of air. Fibers are blown into the interior of the closed mold with the aid of an air current and are deposited in the inner sides of the bottom mold and the top mold, whereby a blank of fiber material is formed, the fibers bound together by a bonding agent, whereupon the blank is hardened into a molded part. A device for the production of three-dimensional molded parts comprises a mold having at least one inlet hole for blowing in the fiber material. The molded part has areas with different thickness.

  • Patent number: 7404921
    Abstract: Free fibers (10) are deposited on a rotary support turntable (30) by means of a hollow deposition cone (40) having an outer wall surrounding a chamber and pierced by multiple perforations. The fibers are delivered to the outer surface of the perforated wall of the cone (40) in a cone feed zone that is remote from the zone for deposition on the turntable (30), and they are then held by suction being established inside the chamber, leading to suction through the perforations in the cone, so as to be transported by rotation of the cone from the cone feed zone to the zone for deposition on the turntable, and the fibers cease to be held on the cone in the deposition zone by localized interruption of the suction through the perforations in the wall of the cone, at least in said zone, such that the transported fibers are deposited on the turntable which is rotated about its own axis simultaneously with the cone being rotated. The fibers deposited on the rotary turntable (30) may be compacted and needled.
