Abstract : A new manufacturing process is described for welding and corrugating cable sheaths. This process makes it possible to use practically all metals which may be of interest for cable sheaths. Moreover, it allows a wide range of wall thicknesses. The resulting sheath is fluid-impervious and combines light weight, exceptional dimensional stability and compression strength with excellent pliability and corrosion resistance. The unusual combination of desirable characteristics has brought about a rapid acceptance of the Wellmantel sheath and its introduction in many countries for numerous cable applications. To date 52 Wellmantel machines are in operation or on order in Europe and in the United States. Since 1951 a total of about 20,000 miles of cables with steel, copper or aluminum Wellmantel sheath have been produced by Hackethal and its licensees. This is a clear indication of the technical and economic merits of the Wellmantel process. The Wellmantel sheath was first introduced in the United States in 1953. Since then, through the pioneering work of our American licensees, the Wellmantel design has found many applications, particularly in the field of communication cables (27). For example, its unique balance of characteristics has led to the design of an extremely vital communication cable which is presently being produced in large quantities. In our paper we have discussed several specific European Wellmantel cable types and their properties. These examples were intended as illustrations of the possibilities which are inherent in the Wellmantel design.
