摘要:
A method for producing a liner hose (2) for lining pipelines, comprising the method steps of moving a circumferentially closed inner film hose (4) over a winding mandrel (6) of a winding apparatus (8) and wrapping the inner film hose (4), which is guided on the winding mandrel (6) by means of a guide mechanism (18), with a fibrous strip (12) which has been impregnated with curable reaction resin, is characterized in that the inner film hose (4) is guided via endless pulling means (14) that circulate without a drive, and in that the inner film hose (4) that has been wrapped with the fibrous strip (12) is moved off of the winding mandrel (6) solely by a pull-off mechanism (16) which acts from the outside on the fibrous strip (12). The invention further relates to a device for carrying out the method.

A method of coating a field joint of a pipeline places at least one body having a thermoplastics material around the field joint. The body is heated in a mould cavity around the field joint to effect thermal expansion of the thermoplastics material. Thermal expansion of the body in the mould cavity is constrained to apply elevated pressure between the body and pipe sections joined at the field joint. The elevated pressure improves bonding and fusing between the body, which forms a field joint coating, and the parent coatings and the exposed pipe sections of the pipe joints. The body need not be fully molten, which reduces the mould residence time including in-mould heating and cooling phases.

A method for joining one or more first-type thermoset components to a second-type thermoset component, each first-type thermoset component being manufactured by providing an uncured starting thermoset component on which a thermoplastic material layer is placed, such that an interpenetrating network forms between the thermoset polymer of the starting thermoset component and the corresponding thermoplastic material layer when each first-type thermoset component is cured; and each first-type thermoset component being then placed on an uncured second-type thermoset component so that when the latter is cured, a further interpenetrating network forms between each thermoplastic material layer and the thermoset polymer of the second-type thermoset component; this results in a strong joint between the first-type and the second-type thermoset components.

A method for manufacturing a plastic fuel tank including: a) inserting a plastic parison including two distinct parts into an open two-cavity mold; b) inserting a core, bearing at least part of a reinforcing element configured to create a link between the two parison parts, inside the parison; c) pressing the parison firmly against the mold cavities, for example by blowing through the core and/or creating suction behind the cavities; d) fixing the part of the reinforcing element to at least one of the parison parts using the core; e) withdrawing the core; f) closing the mold, bringing its two cavities together to grip the two parison parts around their periphery to weld them together; g) injecting a pressurized fluid into the mold and/or creating a vacuum behind the mold cavities to press the parison firmly against the mold cavities; and h) opening the mold and extracting the tank.
摘要:
A process for reinforcing a trim panel for a vehicle using one or more micro-truss reinforcement patches. Each micro-truss reinforcement patch is secured to an inner surface of a show surface panel of the trim panel while it is in a partially cured state and then fully cured. The micro-truss patch is fusion bonded to the panel.

A hand-held device for joining fishing line segments of monofilament, fluorocarbon, and/or braid lines of similar or differing sizes or combinations. The device is electrically powered and is portable. The device includes an encasement for orienting the fishing line segments in a closed chamber in close, tensioned, non-contacting orientation. A material is injected into the closed chamber to encase the lines. This material can be adhesive material or a flowable polymer material having, typically, a melting temperature lower than the line segments to be bonded. Alternatively, A pre-formed, flexible polymer sheath (or sleeve) is used to retain the line segments in the chamber. A heater heats the polymer sheath (or sleeve) within the encasement to allow the polymer to flow and encase the line segments without melting the line segments. Bonding of the line segments can be achieved without melting, abrading, compressing, or impairing the integrity the line segment(s) to be encased. The result is a system that is able to join various types and sizes of fishing line segments together or securing hooks or other components to at least one line.

A method for annularly mounting a band-like filler to the outer periphery of a bead core comprises a step for attaching the filler to the outer periphery of the bead core, a step for grasping the opposite ends of the filler and separating the opposite ends of the filler from the outer periphery of the bead core, a step for sequentially attaching the opposite end surfaces of the filler to each other from the inner peripheral sections of the opposite end surfaces toward the outer peripheral sections thereof, and a step for pressing the portion of the filler, which has been separated from the outer periphery of the bead core, against the outer periphery of the bead core.

The system and method of the present disclosure produces balls that conform in performance and dimensions or dimension range to inflated balls. In an exemplary embodiment of the present disclosure, the balls have a weight that is within a standard weight range of an inflated ball. In another exemplary embodiment of the present disclosure, the balls have a bounce characteristic that is within a standard bounce range of an inflated ball. In yet another exemplary embodiment of the present disclosure, the balls are tuned to achieve an audible response or sound characteristic that is similar to that of an equivalent inflated ball. It should be understood that an exemplary embodiment ball in accordance with the present disclosure can include any combination of features, or all features, including weight, dimensions, bounce, and sound or audible response when bounced.
