Abstract: A method for producing a, in particular thin-walled, pipe conduit element with a surface structure reinforcing the pipe conduit element is proposed wherein the pipe conduit element continuously passes by at least one embossing element guided about the periphery of the jacket thereof and the surface structure is embossed onto the jacket of the pipe conduit element by the embossing element using pure mechanical pressure. For embossing the surface structure onto the pipe conduit element, an arrangement of preferably several embossing elements, in particular balls or rollers are used which are distributed about the periphery of the pipe conduit element jacket. The invention also concerns a device for producing a surface structured pipe conduit element using a guidance having embossing elements and which can be rotated about the periphery of the jacket of a pipe conduit element continuously supplied to the device.

Abstract: The invention concerns a flexible pipe element, in particular for exhaust pipes of combustion engines of motor vehicles, with a helically threaded or ring-corrugated bellows, at least one strip wound hose which is coaxially adjacent to the bellows and which is helically wound or comprises several annular segments, at least one spacer which is disposed locally between the bellows and the strip wound hose and a knitted tube disposed on the outside, wherein the pipe element has an overall maximum rigidity of 5 N/mm.

Abstract: In a device for the bearing of a component of a motor vehicle such as an exhaust gas assembly on the chassis of the motor vehicle, connecting components are provided for mounting respectively to at least the chassis of the motor vehicle and to the component which can move relative to each other, and which engage at least one damped resilient wire element.
