摘要
In a method of automatically closing a large upright sack after filling, the top of the flattened filling end of the sack is folded over onto itself and a closure tape is secured to the folded-over portion and one wall of the sack, whereafter the filling end is re-erected substantially vertically, folded in zig-zag fashion and pulled together to form a frill. The ends of the tape project beyond both sides of the filling end so that, after zig-zag folding of the filling end and tape and after the frill has been formed, the tape ends project from the same side of the frill and can be interconnected.
