Abstract: The present disclosure relates to a method and an extrusion line in which an additive content, in particular, a carbon black content, can be determined inline during extrusion of an extrusion product. For this purpose, an initial measurement is carried out in which a layer thickness and a refractive index of the extrusion product are determined, whereupon a continuous in-line measurement of the current additive content is carried out by a stationary radar measuring device. Thus, the layer thickness is set and the additive content is determined directly by the radar measuring device and controlled by setting the additive feed rate, in particular as a close-loop control.

Abstract: A THz measuring method and a THz device for measuring a container with a joint, in particular, a blow mold container with a pinch-off seam, where a THZ sensor is adjusted relative to a container region in multiple positions with different orientations of the optical axis, THz radiation is emitted as a non-parallel beam bundle from the THz sensor towards the container region, and THz radiation partially reflected on the interior surface and the exterior surface of the container area is received, and one or more of the characteristics of the joint are determined.
