The present invention provides a joining structure with a joining strength higher than that of a conventional rubber core cord joining structure of a rubber ring. The invention also provides a solidifying agent for joining a rubber core cord that provides such a joining structure. A joining structure 2 of a rubber core cord 11 according to the present invention is a rubber core cord joining structure of which opposite end portions of the rubber core cord 11 or end portions of two rubber core cords are joined to each other with an adhesive. A solidified portion 23 formed by a solidifying agent 25 that has solidified is formed at each of the opposite end portions of the rubber core cord 11 or each of the end portions of the two rubber core cords, and the solidified portion 23 contains porous particles. The solidifying agent 25 according to the present invention is a solidifying agent that is applied to the rubber core cord 11, and contains a solvent containing a solidification component and porous particles contained in the solvent.

A method for joining a first component and a second component. The method includes forming a first bond between the first component and the second component by providing a plurality of projections on the first component and embedding the plurality of projections in the second component; creating a fastener hole which passes through the first component and the second component and which encompasses at least one of the projections; and forming a second bond between the first component and the second component by installing a fastener in the fastener hole.

A sizing agent is provided, the sizing agent being blended with a component (A) and a component (B), wherein a mass ratio A/B of the component (A) to the component (B) is 0.5 to 20, and a proportion of a total mass of the component (A) and the component (B) with respect to a total mass of the sizing agent is 80% by mass or more, wherein the component (A) is an epoxy resin having a viscosity of 1 to 180,000 Pa.Math.s at 30° C., and the component (B) is an aliphatic ester compound having a freezing point of 50° C. or lower.

The present disclosure describes light guides and a method of manufacturing light guides that include a rectangular prism-shaped bar, a first polymer or metal cladding on four sides of the rectangular prism-shaped bar, and a second polymer cladding disposed on the first polymer cladding on the four sides of the rectangular prism-shaped bar.

In an embodiment, a paint roller manufacturing system and method uses a fabric-coating applicator to apply a fabric adhesive onto a portion of a perforated paint roller cover fabric material having a plurality of perforations through which adhesive may flow, and into the plurality of perforations and into interstitial spaces of the fabric material, to yield a length of coated fabric. An inner strip and an outer strip are wound about a mandrel in offset relation. A strip-coating applicator is used to apply a strip adhesive to the outer strip as it is wound about the mandrel. Simultaneously with the step of applying the strip adhesive to the outer strip, a portion of the coated paint roller fabric material is received at the outer strip and the length of coated fabric is wound about at least the outer strip to form a paint roller tube.

An assembly to manufacture a roll of prepreg material. The assembly includes a moving system for picking a sheet of prepreg material from a stack of sheets and moving the sheet along a feed path. An alignment system aligns a leading edge of the sheets with a trailing edge of a roll of the prepreg material. A welding system connects the sheet to the roll.

A paint roller manufacturing system and method are described. In an embodiment, an inner strip of material and an outer strip of material are wound about a mandrel in offset relation. The inner strip of material and the outer strip of material each comprise material that results in a final paint roller which shrinks by less than 2.5 percent of the final paint roller axial length, or which has shrinkage that varies by less +/0.1%, upon hardening and setting. An adhesive is applied to at least a portion of the outer strip as it is wound about the mandrel. A length of fabric is wound about at least the outer strip to form a paint roller tube, and compression is applied to the paint roller tube while advancing the paint roller tube in a direction parallel to the mandrel. A precision measuring or sensing device is used to control a cutting device causing the cutting device to cut the advancing paint roller tube into pre-selected lengths prior to the paint roller tube hardening and setting.

A system for forming a thermoplastic may comprise a mandrel configured to receive a thermoplastic charge. The mandrel may rotate about a mandrel axis. A series of rollers may be located circumferentially about the mandrel and configured to apply radially inward pressure. A heating element may be located upstream of the series of rollers.

A method and apparatus for positioning an end effector relative to a fuselage assembly. The end effector is positioned relative to an expected reference location for a reference point on the fuselage assembly using data from a first metrology system. After positioning the end effector relative to the expected reference location, an actual reference location for the reference point on the fuselage assembly is identified using data from a second metrology system. The end effector is positioned at an operation location based on the actual reference location identified.

Methods provide for creating a three-dimensional random fiber orientation in a composite component. According to embodiments described herein, narrow flakes are created from a unidirectional composite fiber tape and poured into a reservoir of a mold, creating a three-dimensional random fiber orientation of the narrow flakes within the reservoir. At least a majority of the narrow flakes have an aspect ratio of length to width of at least 6:1. The narrow flakes are heated and compressed to fill the mold and create the composite component. The three-dimensional random fiber orientation of the narrow flakes within the reservoir is maintained as the narrow flakes are pushed through the mold, creating consistent, uniform strength characteristics throughout the resulting composite component.
