Winding hose for insulating exhaust gas pipe element for exhaust system of e.g. passenger car, has different preprofiled metal bands including band windings circularly connected by solder material in parts around specific degrees

摘要

The hose has different preprofiled metal bands (110, 120) including band windings circularly connected by a solder material i.e. high temperature solder, in parts around 360 degrees. A relative immovability of the connected band windings is raised by the solder material such that the wound hose is stiffeningly or rigidly designed in points, sections or on an entire length. The solder material is liquefied at a temperature of more than 500 degree Celsius. The solder material remains fixed during normal operating temperatures of the hose. An independent claim is also included for a method for manufacturing a winding hose.
