PURPOSE:To achieve a proper sealing with limited power consumption by direct thermal deposition of a synthetic resin film employing a heat generating body comprising a nichrome ribbon (wire) always maintain at the melting point of a synthetic resin or higher. CONSTITUTION:The nichrome ribbon on nichrome wire 8 is arranged along a heater base 7 made of thermally and electrically insulating material such as asbestos plate with both ends thereof connected to a terminal 9 while the top surface is coated with a teflon tape 10 to form a heater section A. A receiving base section B facing it is composed of a receiving base 11 with a silicone rubber 12 attached to the top surface thereof. The nichrome ribbon or a nichrome wire 8 is adapted to always generate heat up to the melting point of wrapping synthetic resin film 13 or higher. Sealing zone 13a of the film 13 is inserted between the heater section A and the receiving base section B, which is driven to approach each other to push the sealing zone 13a for sealing. |
