The method for the manufacture of sporting goods, in particular a shoe, is provided, wherein the sporting goods has a first component with a first connection surface and a second component with a second connection surface. The method includes activating at least one portion of the first connection surface by providing heat energy without contact, and connecting the first component with the second component by joining the first connection surface and the second connection surface.

An article of manufacture comprises a strip that extends along and is centered on a virtual curvilinear path, comprising an arc, having an arc length and a radius. A ratio of the strip-width to the radius is greater than or equal to 0.003. The arc length is equal to or greater than a product of the radius and /64. Within each of discrete strip-regions of the strip, one of the unidirectional reinforcement fibers that is closest to the first longitudinal strip-edge is more buckled than another one of the unidirectional reinforcement fibers that is closest to the second longitudinal strip-edge. Ones of the unidirectional reinforcement fibers that are buckled are parallel to a smallest one of virtual surfaces, joining the first longitudinal strip-edge and the second longitudinal strip-edge.

A welding method heats a surface to be welded of a continuous strip member with a laser beam. The welding method pressurizes the strip member and a continuous film to weld the surface to the film, when or after heating the surface with the laser beam. The welding method preheats the surface before heating the surface with the laser beam. A welding device includes a heat device having an infrared light source disposed to extend along a feed path for the strip member. The heat device is configured to irradiate the surface with infrared light to heat the surface with infrared light. The welding device includes a pressure device configured to pressurize the strip member and the film to weld the surface to the film.

An article of manufacture (200) comprises a strip (202) that extends along and is centered on a virtual curvilinear path (128), comprising an arc (156), having an arc length (154) and a radius (134). A ratio of the strip-width (208) to the radius (134) is greater than or equal to 0.003. The arc length (154) is equal to or greater than a product of the radius (134) and /64. Within each of discrete strip-regions (222) of the strip (202), one of the unidirectional reinforcement fibers (132) that is closest to the first longitudinal strip-edge (204) is more buckled than another one of the unidirectional reinforcement fibers (132) that is closest to the second longitudinal strip-edge (206). Ones of the unidirectional reinforcement fibers (132) that are buckled are parallel to a smallest one of virtual surfaces, joining the first longitudinal strip-edge (204) and the second longitudinal strip-edge (206).

A system and method for welding thermoplastic components by positioning and moving a heated plate between the components to melt their respective faying surfaces, and as the plate moves, pressing the components together so that the melted faying surfaces bond together as they cool and re-solidify, thereby creating a composite structure. The plate has a heated portion which is positioned between and heated to melt a portion of the first and second faying surfaces. A manipulator mechanism moves the plate along an interface from between the portion to between a series of subsequent portions of the first and second faying surfaces, thereby welding the thermoplastic components along the entire interface to create the composite structure. The heated portion may contact the faying surfaces and melt them through conduction, or may be suspended between them and melt them through radiation and convection.

The method for the manufacture of sporting goods, in particular a shoe, is provided, wherein the sporting goods has a first component with a first connection surface and a second component with a second connection surface. The method includes activating at least one portion of the first connection surface by providing heat energy without contact, and connecting the first component with the second component by joining the first connection surface and the second connection surface.

A method or apparatus for joining a first component to a second component with an amalgamation plate includes heating the first component, the second component, the amalgamation plate, or combinations thereof, with either a joining tool or a heating element. The components are attached to the amalgamation plate with the joining tool, such that the first component, amalgamation plate, and the second component are fixedly attached to one another, and the amalgamation plate may be substantially surrounded by the first component and the second component, such that it is hidden from exposure. Portions of the amalgamation plate may be embedded into the components via rotation and/or linear force. A portion of the amalgamation plate may be recessed within the joining tool or an anvil before attaching the amalgamation plate to the either component.

An insulating insert is positioned around a field joint of a pipeline to insulate the field joint. The insert includes a longitudinal series of annular or part-annular filler segments of insulating material, curved about a longitudinal axis, that are each joined to one or more adjacent segments of the series by at least one link. The links may be webs, rods or articulated links. The links are flexible relative to the segments to facilitate bending of the insert along its length by enabling relative angular displacement between adjacent segments of the series.

Methods and apparatuses for bonding polymeric parts are disclosed. Specifically, in one embodiment, the polymeric parts are bonded by plastically deforming them against each other while they are below the glass transition temperatures.
