Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a banding strap for binding, which is mainly used for closing a bag mouth, and is also used as a kind of packaging-related decoration. Regarding improvement.

[0002]

BACKGROUND OF THE INVENTION Generally, candy, chocolate,
The above-mentioned straps are used in place of a ribbon for packaging bouquets or small gifts as well as sealing the opening of a bag containing confectionery such as cookies, thereby increasing the added value of content products. Conventionally, this strap has a hue, gloss, etc. of gold or silver,
A hoop material in which polyethylene is laminated on one side (inner side) of a polyester film on which a brightness-generating agent is vapor-deposited, and a straight core material such as annealed iron wire or heat-resistant plastic wire is integrally sandwiched along the longitudinal direction. It has been made.

Taking the case of using a straightened iron wire as the straight core material in the above-mentioned strap, for example, a heating device for the smoothed iron wire is arranged approximately at the center of the material feeding direction of the manufacturing apparatus. The heated iron wire is linearly supplied from the heating device to the pressure roller group. On the other hand, the above-mentioned plastic film supply drums are arranged above and below the source of the smoothed iron wire, and the upper and lower plastic films are sandwiched by the pressure roller so as to sandwich the smoothed iron wire while tension is applied by the tension roller. Will be supplied to the flock. One of the pressure roller groups is a combination of a heating roller and the other is a silicon rubber roller, and a plurality of groups are linearly arranged side by side. The raw material passing through the pressure roller group is wound in a semi-finished state on a winding roller. Will be taken.

In this apparatus, the polyethylene and polyester constituting the plastic film have different melting temperatures, and the melting temperature of the polyethylene inside is low,
When passing between the pressure roller, that is, the heating roller and the silicone rubber roller, the pair of plastic films are fused and integrated with the smoothed iron wire in between. Normally, a plurality of straight cores such as annealed iron wire or heat-resistant plastic wire are simultaneously supplied in parallel and fed along a guide formed on the heating roller, so that the winding roller has a plurality of cores. The wide semi-finished product having the product will be wound up, then torn to a required width by a slitter, and wound up to a required length or cut into a product.

[0005]

The banding strap as a product thus obtained has a ridge formed along the lengthwise direction with an annealed iron wire or a heat-resistant plastic wire, and has a smooth surface. However, due to the characteristics of the core material, it has a shape-retaining property in a bent state and a deformable and flexible property. However, since this conventional binding strap has a uniform flat shape, it has a limit in design as a decoration, and the attractive effect of recognizing the difference from many displayed products is poor. It has become a thing.

[0006]

SUMMARY OF THE INVENTION Therefore, the present invention has been made by paying attention to the above-mentioned situation, and by solving the above problems, a gradual attractive effect can be obtained if necessary, and a more gorgeous feeling can be obtained. It is possible to bring out the degree of gloss and brilliance in stages as needed, that is, for binding, which can be shrink-processed to a free degree to the band that was only flat in the past. It is an object of the present invention to provide a method of manufacturing a strap and an apparatus thereof.

[0007]

In order to achieve this object, a method of manufacturing a strap for binding according to the present invention uses a flexible straight core material having shape-retaining property in terms of hue, gloss and brightness. In a method for manufacturing a banding strap, which is sandwiched between plastic films containing a generator and which passes through a roller group having at least one of them as a heating roller, irradiating the plastic film with heating light at the entrance of the roller group. In addition, the apparatus for producing a strap for binding has a flexible straight core material having shape retention property and a hue, gloss, and brightness generating agent for sandwiching the straight core material. In a device for manufacturing a banding band for binding, which comprises a group of rollers, at least one of which is a heating roller, which conveys a plastic film at the same time while sandwiching and integrating the plastic film, the plastic clip is provided at the entrance of the roller group. It is characterized by including a light source for irradiating the heating light to the film.

[0008]

As described above, by irradiating the plastic film with heating light immediately before it is sent to the pressure roller, a positive mutation is generated in the structure in which the two kinds of plastics are laminated, and The resulting product is in a shrink state. In order to perform this shrink processing, it is conceivable to use a high frequency in addition to this, or to add processing such as knurling or embossing to the roller, but in the case of high frequency, the cost of the device becomes high, and knurling, embossing, etc. If you use the roller, you can get only standard products according to the processing. In the case of the present invention, with respect to that point, the wavelength of the light source, the temperature of the light source and the heating roller, the pressure value of the roller, or the feed rate of the material can be freely adjusted.
By changing it, it is possible to gradually change the degree of shrinkage.
