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&deg; 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 ( ) in front of and behind the engagement with the pressure roller ( ), and the number of teeth (Z) ranges between 7 and 11, preferably between 8 and 10.

In a process for the continuous production of longitudinally seam-welded and corrugated metal tubes ( ), a metal band drawn off from a supply reel is formed into an open-seam tube, welded at its longitudinal edges, and the welded smooth tube ( ) corrugated. A withdrawal apparatus driven by an electric motor engages the smooth tube. The smooth tube ( ) is corrugated by means of a corrugation plate ( ) located in a corrugation head ( ) which can be driven rotationally. The corrugation head ( ) is driven directly by a hollow shaft motor ( ).

A device (24) is provided for the electromagnetic braking and clutching of at least one storage spool (7). Each storage spool is located on a hollow shaft (5) and can rotate around its longitudinal axis (25). Each storage spool permits strand-shaped materials to be drawn therefrom and strand-shaped materials to be wound thereon when the storage spool (7) is driveably connected to the hollow shaft (5). The electromagnetic braking and clutching device includes a star-shaped support unit (31) that is securely affixed to the hollow shaft (5) and has a number of radially extending holding devices (37) distributed around its periphery. The support unit (31) holds at least one electrically excitable magnet coil (45) radially by using of a holding device (37), at a distance from the hollow shaft (5). The device is particularly suited for braking and clutching storage spools (7) with large outside diameters, which are located on a hollow shaft (5).

A device (1) is used for twisting rope-shaped material (15), particularly of a larger cross section, with changing twist direction (SZ), consisting of a rotor (4) that changes direction and/or RPM, with two opposing chain drives (7) for the material (15), which are parallel to the rotor axis along an endless path. The material is gripped, guided and subsequently released by collet chucks along a prescribed pathway determined by a pressure rail (16). The collet chucks (14) are additionally attached to the chain drives (7) outside of the pathway, and are force-guided along the endless path.

In a process for the continuous production of helical or annular corrugated, thin-walled, in particular longitudinally welded metal tubes, in which a freely rotating roller ring in a turntable corrugation head, which is eccentric with respect to the smooth metal tube, rolls against the smooth surface of the metal tube to produce the corrugation, and the metal tube is transported by a traction device that grips the smooth and/or corrugated metal tube, the force acting on the roller ring is constantly measured, and the rotation speed of the head is controlled as a function of the measured force.

A device for attaching protective insulation to the end of an electric wire, having at least one lead to which a contact element has been attached, includes a carrier (1), equipped with at least three injection dies (3), which can rotate around an axis (A), and of at least one injection molding device (2, 10), located in the circumferential area of the carrier (1). A guide path, extending circumferentially around the carrier (1), is attached to a fixed part of the device. The guide path includes two portions of different radii, extending together nearly 360.degree., which are concentric to the axis (A) of carrier (1), and converge at one end through a transition piece in the guide path. The other ends of the guide path are located at the loading position level (I) of the injection dies (3). The movement of the injection dies (3) is guided by the guide path. The injection dies are closed in the small radius area of the guide path, and are open in the larger radius area. The carrier (1) can rotate in steps of an angle corresponding to the distance of the injection dies (3) from each other.

A cable stranding apparatus is described as having a plurality of stranding rotor units that are interchangeably coupled, in a locked manner, to a single rotor drive assembly of such apparatus. Each stranding rotor unit is designed to accommodate the dimensions of particular cable elements to be stranded. For this purpose, the stranding rotor unit for cable elements of a large cross-section has a plurality of large collets for accommodating the drawing of such large cable elements through the unit; while the cable stranding rotor unit for cable elements of a small cross-section has a plurality of smaller collets for drawing the smaller cable elements through such unit.

A method for the continuous marking of elongated material (1) which is moved in its longitudinal direction, by which ring-shaped markings which are limited in axial direction are applied to the surface of the material (1) by means of ink jets (2). The ink jets (2) emerge under pressure from two nozzles (6, 7) which are arranged parallel to each other and swing continuously on a swing shaft (5). If only one nozzle (6) is to function, the other nozzle (7) is closed by a 3/2-way valve (20). At the same time, a bypass (18) is opened through which the quantity of ink intended for the disconnected nozzle (7) is conducted away. The ink jet (2) of the still functioning nozzle (6) is then retained without change.

Method of marking elongated material

A stranding machine having a stationary stranding head and a revolving storage and holding capstan is improved by winding one or more ribbons upon the bundle of stranding elements as they are being twisted about each other, preferably in an SZ pattern.
