Apparatus for the dry cross linking of strands of elastomer, in particular in the production of elastic cables and multilayered profiles comprises a string of tubes through which the strand passes. Between adjacent tube sections, there are hollow bodies having central cavities in line with the bore of the tubes and a plurality of branch cavities radiating from the central cavity. One of the branch cavities is connected through a UHF transformer and a wave guide with the UHF generator while tuning probes are arranged in other branch cavities. The UHF transformer has an inwardly diverging tapered opening in which a tapered plug of ceramic or plastic is fitted to provide a pressure seal. The interior of the tube sections and the hollow bodies is supplied with inert gas under pressure.
Apparatus for the dry cross linking of a strand of elastomeric material, in particular in electric cable production as well as the production of multilayered profiles, comprising a plurality of aligned tubular sections with a hollow body between adjacent sections through which said strand is passed, said hollow body having a cavity of larger cross sectional dimensions than said tubular sections, UHF generating means connected by a UHF transmission line with said cavity to apply UHF energy to said strand as it passes through said hollow body, UHF coupling means between said transmission line and said cavity, fluid pressure sealing means associated with said UHF coupling means, tuning means in said cavity and means for supplying inert gas under pressure to the interior of said tubular sections and said hollow body.
