Patent Name: Method and device for penetrating thin-film substrates Patent applicant Mundi Dilatation Packing Co., Ltd. Principal Applicant Address Vienna, Austria Inventor Wolfgang Oswald Application (Patent) No. 200380101933.X Date of Application 2003.10 .23 Certification Date Approval Notice No. 1705601 Auditing Notice Day 2005.12.07 Manual CD-ROM D0549 Main Classification No. B65H3/00 Classification No. B65H3/00; B65H3/28; B65B43/26 Sub-priority Original Application No. Priority 2002.10.23 AT A 1609/2002 Abstract The present invention relates to a method and apparatus for penetrating a thin film substrate so that the thin film layers (8) of the most disparate materials can be easily separated. These thin film layers are bonded, material bonded or the like. The adhesion patterns are connected airtight to each other. The separation is effected only with piercing of one layer (18) at a time and it is lifted by rotation by means of a helical thread (16), and gaseous can be introduced in the space formed with the second membrane layer (17). (eg, air) or liquid (eg, water) media. The method and device are characterized in that they are easy to handle and can be applied anywhere on the film workpiece. Therefore, in order to be able to fill such a finished bag later, it is not necessary to consider any additional openings, gaskets, valves, etc. in the film or do not have to consider prior material handling (insert separation means). This minimizes production costs, shortens processing time and avoids material costs or the formation of composite materials due to the introduction of other materials. Sovereignty item 1. A method for penetrating an airtight or directly overlapped film-type substrate or material (8), wherein at least one of the helical end portions (12) of a cylindrical hollow body (3) is controlled The number of rotations and the magnitude of the moment of a cutting surface (14) are such that its determined screw-in penetrates only the required number of film layers.
