Abstract: Described are methods for the manufacture of sporting goods, in particular a shoe, sporting goods manufactured by such methods, for example a shoe, as well as a device for performing such methods. 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.

Abstract: A method includes compressing a non-dielectric, elastically-deformable component, a wire mesh component, and a dielectric, contoured object between first and second forming tools. Once the components are compressed, radio frequency energy is supplied to the first forming tool, thereby causing a radio frequency electromagnetic field to be generated between the first forming tool and the wire mesh component that results in a contoured weld of the contoured object. A tooling assembly is configured to carry out the method.

Abstract: A clip on welder includes two pairs of opposed grippers defined by pivotally attached upper and lower frames for latching the welder to heat weldable material, such as a length of tubing, upon actuation of a start button by an operator; thereafter, the welder operates unattended. At least a jaw of a pair of jaws disposed intermediate the two pairs of grippers heats the material compressed and lodged therebetween to form a weld in or across the material. A source of gas, such as air, under pressure selectively connected to a bellows provides the power to pivot the upper and lower frames into gripping engagement with the material. A source of electrical signals provides the power to heat the material intermediate the pair of jaws. One or more thermocouples senses the heat of the jaws and generates signals used to control the application of power and to control cooling. After completion of the weld, cooling air is directed to the jaws until the thermocouple(s) signal(s) indicates a sufficiently low temperature.
