摘要： A method and apparatus for forming annularly-corrugated tubes and cables utilizing a multiple gear corrugating head which is rotated about the tube or cable, to be corrugated as the tube or cable is drawn through the head. Two or more of the gears each have a different prime number of gear teeth which form the corrugation. A radio-frequency cable formed by the invention exhibit greater consistency and quality than cables produced by conventional corrugating gear heads, and in particular, show improved VSWR characteristics

摘要： A method and device for rolling tube blanks in a planetary skew rolling mill continuously feeds tubular blanks which are to be rolled into the rolling gap end to end. A first tube blank is located in the rolling mill. A second tubular blank following the first tubular blank which is respectively located in the rolling gap of the rolling mill is fed forward with a rotation corresponding to the rotation of the end of the first tube blank caused by the torsion under the rollers in the rolling mill.

摘要： A roller head for a planetary rolling arrangement, said roller head comprising a housing, inside which housing there is rotatably arranged a hollow outer axis and means for rotating said outer axis, as well as inside said outer axis, in a manner that transmits the rotary motion thereof, a center axis which is movable in the axial direction and can be locked in the axial direction, said center axis being provided with a roller. The roller head is characterized by an adjusting axis which is rotatably arranged at the end of the outer axis that is located on the opposite side with respect to the roller and is essentially locked in the axial direction said adjusting axis comprising a counterpart for the threaded section provided in the center axis, and said adjusting axis also including a locking member, which in the locking position forms a friction coupling at least between the adjusting axis and the outer axis.

摘要： 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.

摘要： An apparatus for producing annularly corrugated metal tubes, particularly the outer conductor of coaxial high-frequency cables, using at least one pressure roller revolving around a plain tube. The corrugations are formed in the plain tube by the teeth of the pressure roller, which is rotatable about an axis at a 90° angle to the longitudinal axis of the tube, and the axis of rotation of the pressure roller, itself in a plane perpendicular to the longitudinal axis of the tube, revolves around the plain tube being fed to the pressure roller as the corrugations are produced. The plain tube in turn rotates the pressure roller by its feed. The tips of the teeth are substantially flat, the tube is tightly guided in a guide bushing (12) in front of and behind the engagement with the pressure roller (13), and the number of teeth (Z) ranges between 7 and 11, preferably between 8 and 10.
