Document Type and Number:
WIPO Patent Application WO/2010/023753
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a resin bag production equipment which can reliably produce high-quality resin bags. [MEANS FOR SOLVING PROBLEMS] Three sides on the periphery of a bag body (100) are welded with a welding/cutting device (30) while remaining an opening part (101) unwelded. A port (200) is inserted into the opening part (101), and the opening part (101) is welded to the port (200) with a port welding device (80). In the welding/cutting device (30), the welding is flat welding. On the other hand, in the port welding device (80), when the port (200) is welded to the opening part (101) in the bag body (100), only three-dimensional welding is carried out in such a state that the port (200) is inserted into the opening part (101). According to the above constitution, a deterioration in appearance due to cockling of a film (F) and the formation of a gap due to unreliable welding can be prevented in the periphery of the weld of the bag body (100) and the port (200), and high-quality resin bags can be reliably produced.
