METHOD FOR OPENING THE OPENING OF ANGLE FLOOR BAG WITH GUSSET

摘要

PURPOSE: To positively open the opening portion by providing a pair of wedge plates whose width corresponds to that of a bag and whose bottom is isosceles triangular, by inserting them in the opening of the bag, formed in a rectangular parallelepiped shape, which is opened and folded up, and by enlarging the space between the wedge plates. ;CONSTITUTION: A plate width of wedge plates 2, 2 formed in a approximately home plate shaped, whose bottom is isosceles triangular, is formed so as to correspond to the width in the across direction of the angle floor bag W to attach them to movable brackets 1, 1. Faces of these wedge plates 2, 2 are supported so as to be opposed to each other. After an opening is once opened, the angle floor bag W is set under two wedge plates 2, 2 whose bottom is folded up by the restoration of the gusset. The wedge plates 2, 2 whose space are narrowed are inserted into the opening of the angle floor bag W. Then, the wedge plates 2, 2 are moved in a direction to enlarge the space between the wedge plates. The opening is rightly opened by extending it with the wedge plates 2, 2 until the bend of the gusset is eliminated.;COPYRIGHT: (C)1993,JPO&Japio
