多层包扎容器在制造中为了保证层板的良好贴合,防止筒体出现腰鼓形及筒体两端间隙过大或松动,层板采用横向下料,滚弧方向垂直于板材轧制方向。然而层板在滚弧以后两端会出现一段直边部分(见图1),长度约160～180毫米,这一直边部分在包扎前必须切割掉,否则包扎时贴合不好,导致松动面积超差。多层包扎容器由于受国内层板材 Multi-layer dressing container in the manufacture of laminate in order to ensure a good fit, to prevent the drum appears drum-shaped cylinder and the gap between the ends of the cylinder is too large or loose, laminates using horizontal blanking, rolling perpendicular to the rolling direction of the plate. However, the laminates will have a straight section (see Figure 1) at both ends after the arc rolling, the length of about 160-180 mm, the straight section must be cut off before dressing, otherwise the dressing is not good, leading to loosening area Very bad.
