Rolled film employable for laminating machine

Abstract

This invention is aimed at providing a rolled film employable for supplying a film that is applied a bonding agent on one surface thereof, toward a laminating machine, the rolled film being free from possibility to be arranged in a wrong direction wherein the bonding agent causes a problem. The rolled film is equipped with an axis having both ends respectively having coupling means for coupling the axis with the laminating machine, the coupling means on one axis end does not match the other end of the axis, thereby arrangement of the rolled film in a wrong direction is not allowed.

BEST MODES IMPLEMENTING THIS INVENTION

Referring to drawings, rolled films in accordance with two embodiments of this invention will be described below. More specifically, in the first embodiment, the coupling means is realized by a square groove or a stepped groove 313a or 313b having the width different from each other, and in the second embodiment, the coupling means is realized by a round groove 313a or 313b having the width different from each other.

First Embodiment

Referring to FIG. 6, a film (3) applied a bonding agent that becomes adhesive exclusively under a high temperature, on one surface of the film (3) is wound around an axis (311) to make a rolled film (31) in accordance with the first embodiment of this invention.

Representing the first and second coupling means (313a) and (313b), stepped grooves (313a) and (313b) are arranged respectively at the first end (312a) and the second end (312b) of the axis (311). Representing the first and second accepting means (5a) and (5b), stepped or square projections (5a) and (5b) are prepared on a laminating machine (not shown in the drawings.).

For the purpose to distinguish the first coupling means (313a) and the second accepting means (5b), the width and/or the depth and/or the shape of the foregoing first coupling means (313a) is designed to be different respectively from the width and/or the height and/or the shape of the foregoing second accepting means (5b), and vice versa.

Since the width and/or the depth and/or the shape of the first coupling means (313a) is different respectively from the width and/or the height and/or the shape of the foregoing second accepting means (5b), an action to couple the first coupling means (313a) with the second accepting means (5b) turns out unsuccessful.

Although FIG. 6 shows the difference between the first and second coupling means is limited to the difference respectively in the width, same results are realized by difference in width and/or the depth (height) and/or the shape, as well.

Since the rolled film (31) of this embodiment can not be fit a laminating machine, the foregoing drawbacks are successfully removed.

Second Embodiment

Referring to FIG. 7, a film (3) applied a bonding agent that becomes adhesive exclusively under a high temperature, on one surface of the film (3) is wound around an axis (311) to make a rolled film (31) in accordance with the second embodiment of this invention. Representing the first and second coupling means (313a) and (313b), round grooves (313a) and (313b) are arranged respectively at the first end (312a) and the second end (312b) of the axis (311). The difference between stepped grooves and round grooves is the only difference between the first and second embodiments.

For the purpose to distinguish the first coupling means (313a) and the second accepting means (5b), the width and/or the depth and/or the shape of the foregoing first coupling means (313a) is designed to be different respectively from the width and/or the height and/or the shape of the foregoing second accepting means (5b), and vice versa.

Based on the same principle for the first embodiment, a rolled film (31) in accordance with the second embodiment of this invention can not be fit a laminating machine.

Thus, it is easy to identify whether or not the rolled film (3) matches the laminating machine. Further, it is quite easy to prevent occurrence of a grave accident.

In this manner, the foregoing drawbacks are successfully removed.

The foregoing description has clarified that this invention has successfully provided a rolled film that is free from the drawbacks described above.
