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.

An apparatus for processing a workpiece with ultrasound comprises a base frame having a slide. A tool holder is connected to the slide via leaf springs, whereby a lifting device can move the tool holder relative to the slide.

A sealing jaw assembly for a sealing unit, and in particular an arrangement for suspending a sealing jaw in a socket is disclosed. The arrangement is based on a first and a second spring arrangement wherein the action of the first spring arrangement onto the sealing jaw may be activated and deactivated.

Various device embodiments perform a sealing operation on a moving web, and comprise, among other things a plate assembly with an air cylinder assembly. The air cylinder assembly comprises a mount, a back plate, at least one air cylinder positioned between the mount and the back plate. The first plate assembly further includes a linear servo motor for linearly moving the air cylinder assembly with respect to the first base, and a first tooling plate with a sealing surface area. The first tooling plate coupled to the back plate.

Apparatus (10) and associated method for joining thermoplastic composite components (66, 68) to one another. Firstly, an electrically-conductive carbon-fibre textile (74) is positioned between two pieces of thermoplastic composite (66, 68) to form a weldable assembly (64), and pressure is applied to the weldable assembly (64). A voltage is then applied across the carbon-fibre textile (74) to heat the carbon-fibre textile (74), thereby melting the thermoplastic (82) of a carbon-fibre textile facing surface (78, 80) of each thermoplastic composite (66, 68), wherein the melted thermoplastic (82) fluidly fills the inter-fibre space (84) of the carbon-fibre textile (74). Upon removing the voltage to allow the carbon-fibre textile (74) to cool, a weld (86) forms between the two thermoplastic composites (66, 68) as the thermoplastic sets.
