Abstract

During the production of a tubular insulating body consisting of insulating film layers and metal foil layers, which are placed one on top of the other alternately, for high-voltage units, a continuously fed insulating film strip (3) and a metal foil strip (1) which is inserted in sections between the insulating film layers are wound. In this case, the metal foil strip is provided in a strip material weakening station (7), before said metal foil strip runs into the winding, with weakening regions which are located transversely with respect to the strip and are spaced apart from one another. In order to achieve sections of specific length of the metal foil strip and their arrangement at specific points in the winding, the metal foil strip is fixed in a stop station (6) at specific points in time and for a predetermined time duration. In this case, it tears along one of the said weakening regions. Once the predetermined time duration has elapsed, it is drawn into the winding again, a winding section resulting in which there is no metal foil between the insulating film layers. <IMAGE>
