More particularly, the present invention relates to an automatic molding apparatus for a packaging bag, which uses a polyethylene film to change the position of a carrying handle in forming a bag for a lightweight product, thereby improving portability and durability, And more particularly, to an automatic molding apparatus for a packaging pavement which is capable of reducing production costs.

Generally, the lightweight sanitary article packaging such as rolled toilet paper and disposable diapers is made of a transparent or semitransparent polyethylene tube film.

The conventional packing bag is usually formed in a rectangular shape, and the carrying handle provided therein is formed in a narrow longitudinal direction in consideration of the convenience of manufacturing.

More specifically, for example, wrapping pads of rolled toilet paper are mainly composed of five pieces arranged in the transverse direction and two pieces in the longitudinal direction, in which 10 pieces are packed as a whole. At this time, the carrying handle is formed in the longitudinal direction .

Therefore, when carrying with the carrying handle, a relatively long lengthwise horizontal direction is positioned vertically toward the ground, and the opposite side of the handle touches the ground, or a contact with the carrying person's foot causes a great deal of trouble in carrying and walking .

Particularly, there is a problem in that the load of the packaged product is concentrated, thereby weakening the handle portion, and severely cutting the handle.

On the other hand, in order to solve the contradiction according to the above-mentioned transportation method, a string is passed through the packing stand so that the packing stand can be transported while being positioned in the transverse direction, A method in which a string is tied to a handle is substituted for a handle.

In this case, not only the binding of the strings is troublesome but also the appearance of the merchandise is lowered. In addition, there is a problem that the package is severely damaged in the process of passing the string through the package,

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the conventional packaging stand, and its object is to provide an automatic deflection apparatus for a wrapping pavement bag that can prevent the inconvenience and vulnerability of carrying according to the position of the handle.
