device for the production of behaeltern from metallic material with a heissklebefaehig coated foil

摘要

The press die of insulated material has a h.f. coil attached to it, to which a concentrator is inductively coupled, which, in turn can be coupled to the metal foil. PRef. the concentrator is a slit metal ring separated from the coil and the metal foil by thin metal oxide insulating layers.
