Abstract: A method for monitoring a line is done in a simple manner by feeding test pulses and determining any interference on the test pulses by reflected portions of the same test pulses. In a normal state of the line, the measuring pulses have a transit time which is known in advance due to the predetermined length of the line, and the respective reflected portions of the measuring pulses are generated which propagate in an opposite direction to the measuring pulses. A deviation of the transit time from a previously known transit time, and a deviation from the normal state are recognized in dependence on the overlay.

Abstract: A method for producing an elongated product. By an extrusion unit, a material is extruded onto a core of the elongated product as a casing having a predetermined wall strength. Downstream of the extrusion unit and while the material is still moldable, the elongated product is supplied in a conveying direction to a molding unit. A portion of the material is held by the molding unit and, from the held material, a molded part is formed in an integral manner on the casing. The formation of the molded part is thereby carried out in an advantageous manner, via a deformation of material of the casing.

Abstract: A sensor line for detecting an external influence on a cable is described. The sensor line comprises: a capacitor, a first dielectric, which has a first compressibility and a first permittivity, and a second dielectric, which has a second compressibility and a second permittivity. The first compressibility is smaller than the second compressibility. The first permittivity differs from the second permittivity. The sensor line is configured so that at least the second dielectric is compressible or extensible in the event of a movement of the sensor line, so that a total permittivity, which is composed of the first permittivity and the second permittivity, is variable in the movement of the sensor line. Due to the change in total permittivity, a change in the capacitance of the capacitor can be produced, which is detectable, in order to detect the external influence on the cable.
