  • Publication number: 20040119208
    Abstract: A method for making a polymeric web exhibiting a soft and silky tactile impression on at least one side thereof. The method comprises the steps of providing a forming structure being moveable upon a forming drum and comprising a plurality of protrusions extending from the forming structure, the protrusions being generally columnar forms having an average aspect ratio of at least about 1. The forming structure is disposed adjacent a vacuum chamber and vacuum is applied at a sufficient level to induce a sufficient partial pressure to conform a precursor web to the forming structure, thereby forming the polymeric web. The precursor web can be cast directly onto the forming structure, or it can be re-heated by re-heat means to elevate its temperature sufficiently to permit vacuum formation.

  • Publication number: 20040104509
    Abstract: A metal design panel is constituted by a surface decorative member and a thermoplastic resin member, which are firmly and integrally combined together. A plurality of through holes or dimples are formed at prescribed positions of a metal plate panel, which serves as a surface decorative member, in conformity with an outline of a product completed in manufacture. The metal plate panel is subjected to trimming to remove an unwanted peripheral portion, thus extracting a metal plate therefrom. The metal plate is arranged in a metal mold, into which a melted thermoplastic resin is injected to form a resin layer, which is firmly combined with the metal plate. Alternatively, a core member is formed and extracted from the metal plate panel and is combined with a resin layer upon injection molding.

  • Patent number: 6739024
    Abstract: The invention relates to a method for producing a structured, voluminous non-woven web or velourised film from a thermoplastic by producing an unstructured web and subsequently processing this web using a pair of rollers (10a, 10b). The pair of rollers consists of a positive roller (10a) having numerous positive bodies distributed over the roll sleeve surface and a negative roller (10b) having equally as numerous cavities. During the rolling process, the positive bodies engage with the cavities and stretch the unstructured web in the area of the roller engagements in such a way that a deep-drawn web structure with numerous cavities is produced. After the web has passed through a roller gap, the deformed web, still bonded to the positive roller, is brought into contact with a perforating tool and perforated.

  • Patent number: 6454981
    Abstract: A method for accelerating the release of a flammable blowing agent from an expanded foam is disclosed. According to the method, an expanded foam structure is perforated to form a first series of channels extending partially through its thickness from a first surface and a second series of channels extending partially through its thickness from a second surface opposite the first surface. The channels provide paths enabling the blowing agent to escape more rapidly from the interior of the expanded foam structure.

  • Patent number: 6451241
    Abstract: A sheet of uncured polymer, which is preferably reinforced with multiple layers of fiber, is staged or partially cured to a state in which the sheet is rigid at room temperature. Multiple apertures are drilled into, and preferably through, the sheet. The apertures are for acoustic or laminar flow control, and include holes having diameters in the range of 0.025 to 0.120 inch. In the case in which the fabricated panels must conform to a particular shape, the perforated, partially cured panels are heated to a temperature at which the panel softens, and conformed to the desired surface. The partially cured, perforated sheets are then cured. In order to prevent closure of the drilled holes during the cure, the perforated panel is sandwiched between two layers of glass fabric and cured on an elastomeric tool surface which expands with increases in temperature, forcing the glass fabric to seal the holes during cure. Release coatings are used to aid panel/liner separation.

  • Publication number: 20020109257
    Abstract: Methods and apparatuses for producing fiber-cement soffit building products. In one embodiment of the invention, an apparatus for producing fiber-cement soffits includes a punch assembly, a support assembly facing at least a portion of the punch assembly, and an actuator operatively coupled to at least one of the punch assembly or the support assembly. The punch assembly can include a punch plate and a plurality of punches coupled to the punch plate. Each punch can have a length and a first cross-sectional dimension generally normal to the length. The support assembly can have a support plate, and at least a portion of the support plate is juxtaposed to at least a portion of the punch plate. The support plate can include a plurality of holes arranged in a pattern so that each hole in the portion of the support plate juxtaposed to the punch plate is aligned with a corresponding punch on the punch plate.

  • Publication number: 20020101000
    Abstract: A method for producing filter paper, in particular filter paper for preparing brewed beverages such as coffee or tea employs the steps of producing initially a noncrimped paper of high strength and subsequently rendering this paper capable of filtering through perforation and/or stamping or stamped perforation. The above method is advantageous in that a high production speed of the paper-manufacturing machine results since a crimping device (crimping cylinder, crimping scraper) is no longer required. Accordingly, the bottleneck caused by the crimping device speed is eliminated.

  • Patent number: 6419867
    Abstract: In a method for the manufacture of padding material from inherently rigid flat material, such as cardboard packaging or the like, the flat material is cut into parallel strip sections, which in the vicinity of connecting areas spaced in the longitudinal direction of the strips remain partly interconnected. Between the connecting areas the strip sections are so deformed perpendicular to the flat material extension that transversely adjacent strip sections are bent in opposite directions. A manufacturing apparatus is constructed in the manner of a document shredder with a cutting mechanism having cooperating cutting rollers, which have circumferential grooves, which during the passage of the flat material at regular intervals lead to an interruption of the cut.

  • Patent number: 6419872
    Abstract: A method of manufacturing a part having at least one mechanically weakened area includes a step of producing a thermoplastics material part and at least one cycle of steps entailing forming a localized opening through an area of the part, heating the part locally by means of a heating probe so as to render the aforementioned area of the part plastic, and using a punch to modify the geometry of the area rendered plastic so as to delimit in the part a mechanically weakened area constituting a hole or hole precursor.

  • Patent number: 6395211
    Abstract: A calender for treatment of a web of a nonwoven textile V made of thermoplastic fibers. The calendar includes a heated embossing roller made of steel and a counter-roller that runs at the same circumference velocity. The local plastification in the nonwoven textile V that is produced at the locations of the raised embossing areas results in a board-like feel of the nonwoven textile V. To reduce this hardness, the web of the nonwoven textile V is broken, after having cooled at least partially.

  • Publication number: 20020033563
    Abstract: This invention relates to methods and apparatus for manufacturing shaped polymeric articles by substantially continuous vacuum forming. The method includes providing a sheet of hot polymeric material which is disposed onto a rotating belt having a mold impression. Vacuum pressure is applied to the polymeric material through the belt so as to draw the hot polymeric material into intimate contact with the mold impression to form a patterned sheet portion and a remaining sheet portion. This method thereafter cools at least the patterned sheet portion below a heat deflection temperature of the polymeric material, forms the remaining sheet portion, and then cools the remaining sheet portion below the heat deflection temperature so that features other than the central pattern, such as nail and butt edges, can be mechanically worked into the polymeric sheet.
