<p>PURPOSE: To improve sealing performance by binding the end part of a film casing, ligating the bound part with a metallic clip, abutting an ultrasonic vibration blade to a part projected from there, cutting it and welding a cut part. CONSTITUTION: The end of a cylindrical film casing 1 wrapping food such as ham and kneaded products or the like is bound by binding mechanisms 11 and 12. After the bound part is ligated by the metallic clip 2, an ultrasonically vibrating cutting blade 17 is abutted to the bound part of the film casing 1 projected from the ligating part without using a receiving blade, the excessive bound part is cut and the cut part is welded.</p> |
