  • Patent number: 9505159
    Abstract: A method of dimensionally stabilizing a lumen of a multi-lumen device during manufacture wherein one or more minor lumens may contain a fluid that maintains patency of the one or more minor lumens without the need for a solid core within. The at least one second lumen tube may be in fluid communication with a fluid source during the manufacturing process, such as during extrusion and/or mesh overlay steps. Preventing collapse of the one or more minor lumens during manufacture using a fluid instead of a solid core allows the lumens to have any of a variety of shapes and configurations that would be difficult, cost prohibitive, or impossible for a solid core to be used. Also, obviating the need for a solid core within one or more lumens reduces cost and production complexity. The fluid may be a non-compressible liquid or a pressurized gas.

    Abstract: A laminated touch fastener is made in a continuous process on a mold roll. Flowable resin is pressed against the mold roll in limited areas to form projections extending from resin layers that are laminated to a flexible substrate while carried on the mold roll. In one example a continuous channel about the mold roll is positioned such that the resin at least partially fills the channel as the layers are formed, thereby forming in the channel a raised portion in which the resin layer is of a greater thickness than at a point between the projections and the raised portion. In another example, grooves in the mold roll receive ribs of a pressure applicator during forming of the layers, the ribs blocking lateral flow of the resin to form a desired edge profile.

    Abstract: The invention relates to a pultrusion process in which a continuous reinforcement profile is formed by canting of at least one prepreg strip composed of a fiber-reinforced plastics material. The first shaping of the profile takes place in a preform device, which is downstream of a pressure-molding device for final shaping and prehardening. The movement of the profile takes place synchronously with respect to the operating cycle of the pressure-molding device by means of a traction device. By using a cutting device, it is possible to cut the profile to length and/or to subject edges to subsequent mechanical operations to ensure that correct dimensions are maintained. A continuous (pultrusion) gusset is inserted between the prepreg strips in a radius region of the profile. The gusset has an approximately triangular cross sectional geometry and it is formed by a plurality of continuous fibers braided with one another.

    Abstract: A self-wrapping nonwoven sleeve for routing and protecting elongate members and method of construction thereof is provided. The sleeve includes a non-woven wall having a thickness extending between inner and outer sides. The wall has opposite edges extending along a length of the sleeve between opposite ends. The opposite edges are biased into a self-wrapped configuration by heat-set material of the nonwoven wall to define a tubular cavity. The non-woven wall includes first and second portions extending between the opposite edges. The first portion and second portion have respective first and second thicknesses extending between the inner and outer sides, wherein the first thickness is greater than the second thickness and wherein the first portion provides flexibility to the wall and the second portion is heat set to bias the wall into its self-wrapped configuration.

  • Patent number: 8784716
    Abstract: Method and apparatus for longitudinal orientation of thermoplastic film material (4) comprises a width-reduction zone upstream of the longitudinal stretching zone, through which the width of the film is gradually reduced so as to allow longitudinal stretching without necking. The width-reduction zone comprises at least one, preferably several, pairs of pleating rollers (16, 17) comprising intermeshing grooves or discs for pleating the material, the length of said width reduction zone preferably being less than 3 times the original width of the film. The width-reducing zone has upstream (14) and downstream (15) rollers or roller assemblies, with curved axes and optionally also conveyor belts for providing smooth width reduction. Longitudinal stretching is preferably between at least two, and preferably more than two, pairs of stretching rollers (9, 10, 11, 12) which are relatively close together.

  • Patent number: 8778243
    Abstract: A composite hook and loop fastener in the form of an elongated strip has an elongated loop component, a hook component permanently affixed to the loop component, and a backing layer disposed on a face of the wrap tie in a discrete region. The backing layer is used for permanent attachment of the wrap tie to a supporting surface. One end of the loop component is available for encircling an object to be wrapped and engaging the fastener elements of the hook component. The loop component has a self-supporting web of entangled fibers, the fibers forming both a sheet-form body and hook-engageable, free-standing loops extending from at least one surface of the body, and the hook component has fastener elements extending from a common base. The backing layer may be a pressure sensitive adhesive or a synthetic resin.

  • Patent number: 8765038
    Abstract: A method of feeding a composite molten resin capable of easily forming a multi-kind-multi-layer preform. An apparatus for feeding the composite molten resin has a nozzle portion which includes an outer discharge port in which an outermost annular flow path through which a main layer-forming molten resin flows, meets an outer annular flow path through which a sub-layer-forming molten resin flows inside of the outermost annular flow path; and an inner discharge port in which a shell layer-forming molten resin annularly flowing inside of the outer conflux path, meets the core layer-forming molten resin flowing inside the shell layer; the outer discharge port and the inner discharge port being arranged in this order from the downstream toward the upstream in a direction in which the molten resins flow; wherein provision is made of a shaft-like opening/closing valve for opening and closing the inner discharge port, and a gear pump for intermittently discharging the sub-layer-forming molten resin.

    Abstract: A molding hook and loop fastener includes a plurality of surface fastener portions and a coupling member that is formed of a resilient body and connects the surface fastener portions. The coupling member includes a pair of vertical wall coupling portions which is continuously disposed along a longitudinal direction on both sides in between an engaging element area and which connects the surface fastener portions. With this configuration, when the molding hook and loop fastener is integrally molded to a cushion body, it is possible to prevent a resin material from penetrating into the engaging element area of the surface fastener portion and to stably secure a desired fastening strength at the engaging element area.
