Abstract:
A strip wound hose is provided including a metal band with an approximately S-shaped profile, which is wound in helical windings to form a hose. The profile of the metal band includes two wall sections extending essentially axially and being radially spaced part from each other, which are connected to each other by a web and are each provided at the edge with a bent rim. The profiles of two adjacent windings each are mutually engaged via their rims such that they are axially movable in reference to each other between a compressed position and an extended position. Both the web as well as the rims of the profile are aligned diagonally by an angle of at least 10 degrees in reference to the radial direction. A method for cutting to length and/or widening the strip wound hose is also provided.
