BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for manufacturing a carrying bag used for a carrying bag.

[0002]

2. Description of the Related Art A string is often used as a carrying hand of a carrying bag. Conventionally, the end of the carrying bag is passed through a string passing hole of the carrying bag, and the end is used as a knot to thread the string portion and the carrying bag. It is thicker than the hole. As a result, the end of the carrier will not come out of the string hole.

It takes time and effort to tie the end of the cord into a knot, and the knot becomes thicker.
It is performed in advance to provide a T-shape by providing a stopper at the end of the cord, which is longer than the width of the cord or the cord passage hole of the handbag. In Japanese Utility Model Publication No. 48-20814, a stopper is provided by providing a short bar made of wood or synthetic resin at the end of the hand with a string. In addition, Japanese Utility Model Publication No. 62-35400 discloses a long and thin shape in which a rope body made by loosely twisting a synthetic resin film and a rope made of a synthetic resin film are firmly fixed and cut into a predetermined length. , And the ends of the cord body are welded to the longitudinal center of the hook body to form "T" -shaped cord locking portions at both ends of the cord body.

Further, in Japanese Patent Laid-Open No. 63-222705, a stopper and a stopper at both ends thereof are used, and the stopper is a synthetic resin having a width longer than the through hole of the handbag at at least one location. As a method for manufacturing a carrying bag, which is characterized by being integrally molded with a string, as a manufacturing method of this carrying bag, two mold holes having a stopper shape are provided at a slight interval, and the string is provided in the mold. To perform injection molding of synthetic resin in the mold cavity, then take out the molded product from the mold, and finally cut between the two resins integrally molded on the string to form the stopper. It is stated.

[0005]

However, the above-mentioned Japanese Unexamined Patent Application Publication No.
The method of manufacturing the handle in 3-222705 is to perform injection molding of synthetic resin in the mold cavity, then take out the molded product from the mold, and then wind the string into a roll shape, While unwinding this roll, the two resins integrally formed on the cord are cut, and so to speak, the two steps of resin molding and cutting must be performed with some time left.

The object of the present invention is to eliminate the disadvantages of the conventional example, and to form a synthetic resin stopper having a width longer than the through hole of the handbag in the end portion of the cord serving as the handbag for the handbag. An object of the present invention is to provide a manufacturing method and a manufacturing apparatus for a handbag for a handbag that can be easily formed.

[0007]

In order to achieve the above-mentioned object, the present invention provides two mold holes each having a rib-like stopper shape which is attached to an end of a cord so as to sandwich the cord with a slight interval. A cutter that inserts between the mold holes and cuts the strings between the mold holes is installed in a mold that is provided side by side and that can supply the strings so as to penetrate the two mold holes. Using a handbag manufacturing device for a handbag provided with a resin supply device for supplying a synthetic resin to a hole, a string is supplied into the mold hole so as to penetrate the mold hole, The gist of the present invention is to cut the string by the cutter in the vicinity thereof, then injection-mold synthetic resin into the mold cavity, and form the stopper at the end of the string into a rib shape on the outer circumference.

[0008]

According to the present invention, the stopper of the carrying handle can be attached by injection molding near the cutting point after cutting the cord, and these steps can be performed as continuous steps by the apparatus.
