Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding band for winding and binding a plurality of bundled wire rods, and in particular, cutting a band bundled by winding a bundle of electric wires bundled in the middle. Also relates to a binding band that can be rebound.

[0002]

2. Description of the Related Art IV for wiring in houses, buildings, factories, etc.
Although electric wires and VVF electric wires are used, these electric wires are generally used in the form of a bundle-wound electric wire that is wound into a ring and bundled for ease of handling during storage, transportation, and use. There is. In the bundle-wound electric wire, usually, as shown in FIG. 4, the electric wire 1 is wound around a certain length in a ring shape to be bundled, and a binding band 2 is wound around an appropriate place (usually 2 to 4 places) to be bound. This binding band 2 is conventionally shown in FIG.
As shown in FIG. 5, a film made of a heat-fusible resin is formed in a tape shape. That is, the binding band 2 is formed by winding the electric wire 1 in a ring shape to form a bundled electric wire, and then winding the electric wire 1 at a plurality of places (two places in FIG. 4), overlapping both ends thereof, and heating the overlapped portion. Then, they are heat-sealed and fixed.

[0003]

Such a conventional binding band 2 is formed by winding the electric wire 1 in a ring shape to form a bundled electric wire, and then winding the electric wire 1 at a plurality of locations (two locations in FIG. 4). Since the parts are overlapped and the overlapped part is heated and heat-fused to be fixed, when the electric wire 1 is unwound from the bundle-wound electric wire, the wound binding band 2
After disconnecting all, take out. In this way, when the binding band 2 is cut with a knife such as a knife and the electric wire 1 is unwound from the bundle-wound electric wire for a required length, and the remaining bundle-wound electric wires are to be bound again, use the binding band 2 cut once. In that case, there is a problem that it is necessary to overlap the cut portions and apply heat again to fuse them, which is troublesome and cannot be tightly bound.

The object of the present invention is to provide a cutting method in the case of cutting on the way.
It is to be able to easily re-bond without re-fusion.

[0005]

In order to achieve the above object, the present invention provides a binding band according to claim 1, which binds a plurality of bundled wire rods and is formed into a tape shape. The adhesive film is formed by laminating the upper and lower layers, and a peelable adhesive layer is interposed between the upper and lower laminating surfaces.
With this configuration, according to the invention of claim 1, one end of the upper and lower bonded films can be peeled up and down, and the other ends of the upper and lower bonded films can be sandwiched and bound. When cut by, it can be easily re-bonded without re-fusion.

In order to achieve the above object, the present invention provides the binding band according to claim 2 in the binding band according to claim 1, in which both side end portions of the heat-fusible film are provided. From this, slits are formed with a space from the opposite side ends. With this configuration, according to the invention of claim 2, the slits can be engaged with each other, and when the slits are cut halfway,
Can be easily re-bonded without re-fusion.

[0007]

FIG. 1 shows another embodiment of the binding band according to the present invention. In the figure, 6
Is a binding band for winding an IV electric wire, a VVF electric wire, or the like around a bundle of electric wires wound in a ring shape, and is a first layer 7 formed of a heat-fusible film and a second layer formed of a heat-fusible film. The first layer 7 is formed by bonding 8
An adhesive layer 9 is interposed between the second layer 8 and the second layer 8. The adhesive layer 9 is made of a re-adhesive material such as a rubber adhesive or a hot melt adhesive.

The binding band 6 is formed by bonding a heat-fusible film first layer 7 and a heat-fusible film second layer 8 with an adhesive layer 9 to form a tape shape. Slits 10 are formed at one side end of the binding band 6 toward the other side end at regular intervals. Also,
On the other side end portion of the binding band 6, slits 11 are arranged at regular intervals toward one side end portion and are displaced from positions of the slits 10 provided on the one side end portion of the binding band 6. (Ideally, it is provided at an intermediate position between the two slits 10). That is, slits 10 and slits 11 are alternately formed at regular intervals from both end portions of the binding band 6. The lengths of the slits 10 and the slits 11 (the lengths from the side end portions of the binding band 6 toward the opposite side end portions) do not need to be the same, but it is preferable that they are the same. The depth (length) of the slits 10 and 11 is 1 / the width of the banding band 6.
It is formed to 10 to 1/2. The heat-fusible film first layer 7 and the heat-fusible film second constituting the binding band 6
Layer 8 is polyethylene (PE), polypropylene (P
P), polyvinyl chloride (PVC), polyethylene terephthalate (PET), etc. are used. The materials forming the heat-fusible film first layer 7 and the heat-fusible film second layer 8 do not necessarily have to be the same.

The binding band 6 thus constructed is used by re-binding as shown in FIG. That is, when the bundle-wound electric wire as shown in FIG. 4 is unwound, the binding band 6 for binding the bundle-wound electric wire is cut with a knife or the like to unwind the electric wire from the bundle-wound electric wire by a necessary length, and then the remaining When the bundled electric wire is to be bound again, it is wound around the remaining bundled electric wire again using the binding band 6 cut at one end, and the heat-bondable film first layer 7 and the heat-meltable film 1 at the cut end of the binding band 6 are melted. Between the heat-sealable film first layer 7 and the heat-sealable film second layer 8 at one end where the adhesive film second layer 8 is peeled off and the other end of the binding band 6 is cut The other end of the banding band 6 cut by the adhesive layer 9 left inside the heat-fusible film first layer 7 and the adhesive layer 9 left inside the heat-fusible film second layer 8 And bond them together. By doing so, both ends of the binding band 6 cut at one end can be easily and surely bound without overlapping and heating and re-fusion.

Further, the binding band 6 shown in FIG. 1 can be re-bound as shown in FIG. That is, FIG.
When unwinding the bundled electric wire as shown in (4), the binding band 6 that binds the bundled electric wire is cut with a knife such as a knife, and after the electric wire is unwound from the bundled electric wire for a required length, the remaining bundled electric wires are removed. When tying again, use the tying band 6 cut at one end to wind the wire around the remaining bundled electric wire again, stack the ends,
Slit 10 and slit 11 formed in the binding band 6
Bite and bind together. By doing so, both ends of the binding band 6 cut at one end can be easily and surely bound without overlapping and heating and re-fusing, so that the two-layer structure is high. Can maintain strength.

[0011]

Since the present invention is constructed as described above, it has the following effects.

According to the first aspect of the present invention, one end of the upper and lower laminated films can be peeled up and down, and the other ends of the upper and lower laminated films can be sandwiched and bound together. In addition, it is possible to easily re-bond without re-fusion.

According to the second aspect of the present invention, the slits can be engaged with each other, and when the slits are cut in the middle, they can be easily re-bonded without re-fusion.
