发明名称 ストリップ重ね合わせ接合技術
摘要 The present invention concerns a method of splicing two sealing strips and a sealing strip formed by the method. The sealing strip is placed at longitudinal edges of a packaging material web, used for packaging containers for liquid foods. The sealing strips to be spliced are cut each forming an oblique edge of about 45°, as seen in plan view. The oblique edges are then placed one on top of the other forming an overlapping area. The overlapping area is in the form of an oblique band having a length of about 3 mm. The ends of the sealing strips are then fused together by heating both from one side at the overlapping area.
