摘要： PROBLEM TO BE SOLVED: To provide a method for narrowing down and a mechanism for narrowing down in advance a bag opening side capable of forming a neck part with a required length so as to ensure an interval enough for bundling. SOLUTION: When a bag is bundled, the neck part N is formed by pinching the bag opening side of the bag B at two positions 20 and 30 separated from each other in the up and down direction, flattening the bag B between them, enlarging the interval of two positions 20 and 30 in the up and down direction while the flattened bag opening side F of the bag B is inserted into an opening part for narrowing gradually the width. By narrowing the width to a required length to form the neck part N, a bundling work for winding a bundling tape and a work for cutting an excess margin can be easily performed. In addition, wrinkles, slacks or the like generated when it is narrowed down, can be removed from the neck part. COPYRIGHT: (C)2005,JPO&NCIPI
