2. Description of the Related Art Conventionally, clothes that have been cleaned by a laundry store have been packaged in printed paper. However, the hygroscopicity of paper is disliked, and the price of its use is low. , Because the surface gloss gives a favorable impression, and the material is extremely thin and easy to handle,
The use of storage pads made of plastic film has become overwhelming.

Furthermore, in recent years, a large amount of plastic non-woven fabrics having high air permeability and strength of use have been distributed, and although storage pads using the same have come to be seen, Since the non-woven fabric has the opposite property of lacking transparency, it is not easy to immediately check the contents after packaging from the outside, and it is difficult for printing ink to spread on the surface of the non-woven fabric. Non-woven,
A storage pad having a transparent film on one side is processed by an adhesive treatment of a polymerized surface using an adhesive.

However, in the case of joining with an adhesive, a flammable solvent must be used as a solvent, and the gas emitted by the solvent has an irritating property. Appearance was desired.

On the other hand, although a heat-bonding method using high frequency is often used for bonding a plastic film, it is not easy to set conditions for bonding two films made of different materials, and a transparent film Since it is likely to cause breakage and shrinkage, it was not a suitable method for mass-producing storage pads using an automatic device.

[0006]

SUMMARY OF THE INVENTION In view of the above situation, the present invention uses two kinds of materials, a non-woven fabric and a transparent film, in a large amount and efficiently so that the non-woven fabric can keep its folds on its side surface. It is an object of the present invention to disclose an apparatus for automatically producing a storage pad manufactured by the above method.
