  • Patent number: 10399276
    Abstract: An automated in-line feed-through system and method, integrates the ability to control one or more variables during part fabrication with the layup of one or more fiber tows to form a composite part. The system includes an automated layup system configured to receive a feed-through of one or more fiber tows as an input material. The automated in-line feed-through system further includes a controller configured to respond to measurement data obtained by one or more samplings of the input material and/or a plurality of laid up plies that form a laminate. The controller in response to the obtained measurement data provides adjustment of the feed-through of the one or more fiber tows to compensate for a variation in one or more of the weights from a reference weight.

  • Patent number: 8075722
    Abstract: In a manufacturing apparatus of an absorbent product, extended elastic yarns to be a first middle elastic member and extended elastic yarns to be leg elastic members are bonded between a first sheet and a second sheet and arranged crossing each other in manufacturing an outer covering sheet. A first middle elastic member and an inclined part of the leg elastic members crossing the first middle elastic member are simultaneously and reliably cut in a crossing area of the both elastic members by first cutting blades tilted relatively to a direction where the first middle elastic member is positioned and second cutting blades tilted relatively to a direction where the inclined part is positioned. Thus, it is possible to easily form the outer covering sheet which maintains elasticity in a required portion and has high flexibility.

  • Patent number: 8062448
    Abstract: A plurality of unidirectional sheets (30a, 30b, 30c) are superposed in different directions and they are bonded together. At least one of the unidirectional sheets is made by spreading a tow so as to obtain uniform thickness, width not less than 5 cm, and a weight of no more than 300 g/m2, cohesion being imparted to the sheet so as to enable it to be handled prior to being superposed with other sheets. Advantageously, the unidirectional sheets are made of carbon fibers and are obtained by spreading out large tows.

  • Patent number: 8007894
    Abstract: A process for continuous, tailored lamination of aligned composite materials in such a way that either pre-formed or pre-consolidated sheets are made available for subsequent infusion molding or stamping processes, the process comprising the steps of: material placement, consolidation/stabilization, cut and kit, fabrication, and final trim. A tailored blank machine is also described. The blank machine includes a series of material placement heads arranged in a linear or serial fashion along a single moving placement table, wherein each head lays down a single angle of the prescribed stacking sequence as the conveyer passes under the head at a constant speed wherein the angle is proportional to head traverse rate divided by conveyer speed.

  • Publication number: 20100291827
    Abstract: The invention relates to a new base interlining for producing roofing membranes which have to meet a wide variety of requirements. The new base interlining provides a sufficient mechanical stability, good perforation strength, good tensile strength and a high resistance to thermal stress, inter alia required for base interlining during bituminization. In addition, the new base interlining requires a considerable reduced volume of impregnating bitumen when producing bituminized roofing materials and therefore high costs of special bitumens for filling the base interlining can be avoided. Beside the new base interlining, a method for producing it as well as roofing membranes comprising the base interlining are subject matter of this invention.

  • 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.
