    Abstract: A system for diffusing wrinkles in a composite laminate may include at least one wrinkle diffuser. The wrinkle diffuser may include a diffuser body may be mounted to a tool in a manner such that a composite ply at least partially overlaps the wrinkle diffuser. A plurality of diffuser elements may be formed in the diffuser body to define a corrugated surface. The corrugated surface may cause a portion of the composite ply to assume a corrugated shape when a compaction pressure is applied to force the composite ply against the corrugated surface. The wrinkle diffuser may include an indexing feature to index the wrinkle diffuser to a ply edge of the composite ply.

  • Publication number: 20150104614
    Abstract: A method of forming a continuous sheet of pleated, hook-form, fastener product includes training a substrate about a pressure roll having an outer surface defining circumferential grooves. As the substrate approaches a nip between the pressure roll and a mold roll calendered with the pressure roll, a portion of the substrate is disposed within a corresponding one of the grooves between the pressure roll and a stationary horn extending into the groove whereby a longitudinally-extending pleat is formed in the substrate. The pleated substrate is then passed through the nip where resin regions are laminated to a side of the substrate opposed to the pleat.

  • Publication number: 20140367885
    Abstract: Methods of incrementally stretching thermoplastic films in the machine direction include elongating the films in the machine direction without reducing the films' machine-direction tear resistance. In one or more implementations, methods of incrementally stretching thermoplastic films include reducing the gauge of the films without reducing the films' machine-direction tear resistance. The methods can involve cold stretching the films and imparting transverse-direction extending linear rib pattern into the film. The linear ribs can have alternating thick and thin gauges. Incrementally stretched thermoplastic films can have a machine-direction tear resistance that is approximately equal to or greater than the machine-direction tear resistance of the film prior to stretching.

The forming device includes opposing arrays of flute-forming bars that can be interlaced to define therebetween a longitudinal flute-forming labyrinth effective to reduce the width of a web traveling therethrough by a preselected take-up ratio. The flute-forming bars are curved beginning at an entry end of the forming device such that they converge in a lateral direction as they proceed in the machine direction. In this manner, individual elements of the web traveling between the respective arrays in the machine direction follow contour lines along the curved bars or between adjacent ones of the curved bars so that no such element crosses any flute-forming bar in the cross-machine direction as the web travels and is fluted. A corrugating die for introducing a near-net shape to the intermediate-fluted web is also disclosed, as are a corrugating line incorporating these operations and methods for its operation.

    Abstract: A method of stably producing a ceramic sheet with good quality, where the tip portions of convex parts constituting numerous wrinkles on the surface of the ceramic sheet are not in contact with each other, and concave parts are open. To produce the ceramic sheet, clay is placed on the upper surface of a stretched rubber sheet, and the upper surface of the clay is covered by a surface layer made from a material that burns when the clay is baked. The rubber sheet is contracted to form wrinkles on the upper surface of the clay and the surface layer. The clay is baked and the surface layer is made to disappear by burning to obtain the ceramic sheet. Thus, the surface layer prevents the tips of the convex parts constituting the wrinkles from being in direct contact with each other.

  • Patent number: 7235115
    Abstract: The method of forming pleated filter media includes providing a generally planar web of filter material, folding the web to form a pleated web having a plurality of fold lines, arranging the plurality of pleats in a first spaced configuration defined by a first distance between adjacent pleat tips, applying a continuous strand of adhesive to the web, and adjusting the arrangement of the plurality of pleats into a second spaced configuration defined by a second distance between adjacent pleat tips. The web has a front face and a rear face. Each fold line is intermediate oppositely sloping first and second wall surfaces. The plurality of fold lines form a plurality of pleats having a first plurality of pleat tips and a second plurality of pleat valleys. The second distance is different from the first distance.

  • Patent number: 7097803
    Abstract: The present invention is to provide a process of making a corrugated net material including the following steps. First prepare a net material with an adequate length, and then heat and soften the net material by means of a heating element. March the soften net material through a gap formed by two press rollers which rotate in relative direction such that the softened net material is pressed by the two press rollers flatly. March the pressed flat net material continuously into a vessel such that the flat net material is cumulated in the vessel and squeezed by itself to form a plurality of non-directional bends. Lastly, release the squeezed net material from the vessel such that the corrugated net material is thus obtained.

  • Patent number: 6953542
    Abstract: A closure device for a thermoplastic bag which includes two opposing, longitudinally extending interlockable male and female fastening strips having respective male and female closure elements or profiles that are deformed to interdigitate and produce an audible clicking sound and or tactile effect that is perceptible to the touch as the closure device is opened and closed. Interdigitation of the two profiles is achieved by cold forming the profiles while interlocked. The shape of the cold form is a stepped deflection of both profiles so that their shapes are generally congruent. The stepped deflections provide a change in the occlusion and peel force of the interlocking closure device thereby resulting in an audible clicking or popping sound as the closure device is opened and closed and a tactile effect that is perceptible to the touch as the closure device is closed.

  • Patent number: 6932850
    Abstract: A filter may comprise a plurality of pleats, at least one pleat including a pair of pleat legs and pleat tip region. In some embodiments, a thickness of pleat tip region at a point spaced about one to four pleat leg thicknesses from the end of the pleat tip region may be less than or equal to about twice the pleat leg thickness or may be less than or equal to a distance between corresponding points on opposing outer surfaces of the pleat legs. A filter may comprise a pleated structure having a plurality of pleats. In some embodiments, the pleated structure may have more than one layer and at least one of the pleats may have a reformed pleat tip region. In other embodiments, the pleated structure may have a pair of pleat legs and at least one of the pleats may have a reformed pleat tip region and contacting pleat legs. A filter may comprise a plurality of pleats, at least one pleat including a pleat tip region having contacting inner surfaces.

  • Patent number: RE39968
    Abstract: The present invention relates to a polytetrafluoroethylene (PTFE) tube, and more particularly to a PTFE tube for a flexible hose. In particular the invention relates to a PTFE tube having a smooth bore for use in the production of a lined hose assembly farther comprising hose braids, external hose protection and end fittings. The PTFE tube comprises external roots and peaks, which tube is obtainable from a non-convoluted tube having an original wall thickness W0 and an internal diameter ID by a process in which a region of the tube is thinned to provide external convolutions with a root wall thickness W1 characterised in that the convoluted PFTE tube has an improved resistance, of greater than 7.6%, to permeation by comparison with the non-convoluted tube, the comparison being made between tubes of (i) equal nominal bore ID; and (ii) equal weight of PTFE per unit length.
