  • Patent number: 4690668
    Abstract: A method and an apparatus for heat welding a butt seam on a tube of packaging material, in which the welding heat is generated by applying a high-frequency alternating electromagnetic field of a pair of induction coils. To prevent current arcing at the cut edges of a metal inlay of the packaging material in the vicinity of the abutting edges of a sheet of packaging material, the edges are guided spaced apart from one another by a predetermined distance. To this end, the apparatus has a separating blade, which in the operative range of the electromagnetic alternating field protrudes in between the abutting edges of the sheet of packaging material and between the induction coils.
