Description

[Detailed description of the invention] The present invention is a wrapping paper, more specifically a wrapping paper for a cylindrical coil such as an iron plate, which wraps a roll-shaped coil such as an iron plate coil, more specifically a wrapping paper for a cylindrical coil such as an iron plate. To provide a completely new and useful wrapping paper in which wrapping paper can be reliably and completely wrapped around both inner circumferential surfaces of a mounted iron plate coil, etc., and the wrapping paper will not peel off from both inner circumferential surfaces at all. There is something to do.

Conventional wrapping paper, such as kraft paper, is
The surface of the cylindrical coil is wrapped while automatically unrolling the wrapping paper wound into a roll. Next, the edges of the wrapping paper are folded into the inner peripheral surface on both sides of the cylindrical coil, and the pressure drum is shaped into a cylindrical shape. The coil is wrapped by inserting the wrapping paper into the inner circumferential surfaces of both sides of the coil and rotating the wrapping paper so that the edges of the wrapping paper are pressed and folded into both sides of the cylindrical coil.

However, the edges 5' of the wrapping paper 5 that wrapped the cylindrical coil in this way are only pressed against the inner circumferential surface of the cylindrical coil 2 by the pressure drum, so the wrapped state is as shown in FIG. In this case, the wrapping paper bulges from both ends of the cylindrical body 2, causing the edges 5' of the wrapping paper 5 to be peeled off, which is a fatal drawback of this type of wrapping paper.

The present invention was devised to eliminate all of these drawbacks, and its feature is that the wrapping paper body is formed to have a predetermined width according to the dimensions of the cylindrical coil of the iron plate, etc. to be wrapped. It consists of a plurality of iron wires buried at predetermined intervals in one direction.

The specific configuration thereof will be explained below according to an embodiment shown in the drawings.

1 is a predetermined value 4 based on the dimensions of the cylindrical coil 2 made of iron plate coil.
The wrapping paper body is made of a waterproof material laminated with wide polyethylene fiber cloth, and has several iron wires 3 embedded in it in the vertical direction and at predetermined intervals in the horizontal direction, as shown in Figure 1. .

The present invention relates to the elongated wrapping paper 4 having the above-mentioned structure. Examples of its use include, for example, winding up the wrapping paper 4 into a roll, wrapping it around the outer periphery of the cylindrical coil 2, and wrapping the surface thereof. Automatic cutting and surface packaging.

Thereafter, the edges 4' of the wrapping paper 4 are folded into the inner circumferential surfaces 2' on both sides of the cylindrical coil 2 using an edge folding machine and folded into the inner circumferential surface of the cylindrical coil 2. Complete packaging is possible.

The thus-wrapped cylindrical coil 2, especially its inner circumferential surfaces 2' on both sides, is packaged in such a way that the iron wire 3 is interposed between the tabs 4' of the wrapping paper 4, as shown in FIG. The tabs 4' are easily folded into the shape of the inner circumferential surfaces 2' on both sides of the cylindrical coil 2, and at the same time, the folded tabs 4' are securely and completely folded into the cylindrical inner periphery without fear of peeling off due to the interposition of the iron wire 3. Closely adheres to the surface.

In other words, the iron wire 3 acts as a core material for the folded edge piece 4' of the wrapping paper 4, and once it is folded in, the iron wire 3 is also bent along the folded edge piece 4'. There is no risk of it peeling off from the inner circumferential surface 2', and it can be firmly attached.

In this embodiment, the iron wires 3 are inserted vertically and horizontally in the wrapping paper main body 1, but they do not necessarily need to be inserted vertically and horizontally, and may be inserted only in the horizontal direction, for example, as shown in FIG.

The point is that the iron wires may be inserted at predetermined intervals in the direction in which the edges of the wrapping paper are folded, that is, at least in the axial direction of the cylindrical coil.

Furthermore, the material of the wrapping paper is not limited to the examples.

As mentioned above, the present invention is a wrapping paper in which a plurality of iron wires are inserted into the wrapping paper body at least in the folding direction of the flaps of the wrapping paper body, so that a cylindrical body in which a coil of iron wire is wound with the wrapping paper is formed. When wrapping the cylindrical coil, the edges of the wrapping paper folded into the inner circumferential surface on both sides of the cylindrical coil are securely folded inward by the action of the iron wire as a core material, and there is no risk of them peeling off from the inner circumferential surface after that, and the edges of the wrapping paper are folded into the inner circumference on both sides of the cylindrical coil. A very special action and effect was achieved by closely adhering to the inner peripheral surface of the shaped coil.

Therefore, although the packaging of this kind of cylindrical coil was conventionally very complicated, the development of this wrapping paper has achieved a particularly remarkable effect in that it can be packaged very smoothly and compactly, and with a good appearance.

Furthermore, since the iron wires are embedded within the wrapping paper body at predetermined intervals, the iron wires cannot necessarily be bent or bent freely, but the wrapping is done in a manner that conforms to the shape of the packaged item. It has the advantage of not losing any of the original functions of paper.

In addition, it has great practical effects such as a simple configuration.
