The cooled current conductor and the insulator form a unit, and a counterpiece is provided as is at least one electrically conductive sheet which is heated inductively by a current produced by the magnetic field. The unit and the counterpiece are movable to and from each other to produce a mechanical pressure force on plastic sheets arranged between them and the electrically conductive layer for freeing from the formed weld. The unit includes the electrically conductive sheet and the arrangement incorporates two units, each incorporating a cooled current conductor, an insulator sheet and an electrically conductive sheet, placed on opposite sides of the weld area. The electrically conductive layer or sheet is covered by a release sheet on the surface turned towards the weld area. |
