Disclosure of invention The present invention provides a handle for gripping and/or loading a bag made of a flexible synthetic resin material. It is also a method to attach a surface film for reinforcement, and it is also possible to provide a continuous surface film layer for reinforcement. A film is provided with the above-mentioned handle before forming the film into a bag for filling liquid. The present invention provides a method characterized by adding.

The handle for gripping and/or loading may be constructed of thread or of suitable hardness. It is convenient to construct the wire with a coated wire made of a synthetic resin material.

Preferably, the handle is added to the edge of the film during printing of the image or the like on the film. .

The present invention provides a handle for gripping and/or loading a bag made of a flexible synthetic resin material. It is a device for attaching a reinforcing surface film layer continuously. A film is provided with the above-mentioned handle before forming the film into a bag for filling liquid. The handle for gripping and/or loading is constructed by a thread. It consists of a coated wire made of synthetic resin material with moderate hardness, In addition, the above-mentioned handle is something that is added to the edge of the above-mentioned film while printing a pattern etc. on the above-mentioned film. the law of nature, For replenishing the above-mentioned thread or coated wire material made of moderately hard synthetic resin material. Meno magazine and The above thread or cover! a device for unraveling the 111S material and drawing it into the guide tube; 1. Transfer the free end of the above thread or coated wire to the edge of the above film by the desired length. a guide for feeding and an ejection means; - said filament defined by said guide means; Or melting/cutting the coated wire to the desired length and welding it to the above film. a device; It is characterized by having the following.

The present invention is based on the following description of non-limiting embodiments and with reference to the drawings. Even better (as will be understood).

Brief description of the drawing FIG. 1 is a longitudinal sectional view of a device according to the invention for realizing the method according to the invention; FIG. 2 is a plan view of FIG. 1.

BEST MODE FOR CARRYING OUT THE INVENTION The film 1 shown in FIG. 1 has a continuous surface film 2 on its surface as shown in FIG. It was established in

As mentioned earlier, this film passes through the device under tension, It is shaped as a pouch made of flexible material and can be filled with liquid.

A means for attaching a handle for gripping and/or lifting according to the invention to the above device. To add, A well-known pulling device 4 is attached to the magazine 3 for replenishing the line or coated wire. height, It consists of a sleeve 5 and a guide sheath body 6 for conveying the yarn or coated wire. has a guide means for - a melting/cutting device 7 for guiding and injecting the thread or coated wire into a desired length; It has means 8 to do so.

The guide and injection means 8 consist of a pair of molds 9.10, these molds 9.10 is provided with a flap to release the thread or coated wire when it is welded to the film. It is movable relative to the plane of the film 1 in a direction perpendicular to it.

These molds define a passage 11 within which the thread or coated wire passes. It penetrates and reaches the right place in the film due to its desired length.

The proximal end 12 of the passage 11 is widened, and the thread or coated wire is introduced into the base end 12 of the passage 11. It's easy to do.

When the thread or coated wire is introduced into a predetermined position by the drawing device 4, it melts. / Attached to the edge of the film 1 by a cutting device 7. The melting/cutting device 7 is The dynamic nipper has a body 13, the body 13 is an opposing support stop provided on the mold 9. Collaborate with 14.

Of course, the device can be operated continuously or supported. , preferably operated in the horizontal direction, and equipped with servo systems, automatic control equipment, etc. If you can understand it, you can adopt it.

The film with the handle 15 attached thereto is then conveyed to an unspecified molding machine.
