BACKGROUND OF THE INVENTION
The present invention relates to a winding method for winding a metal foil of mild steel, Invar, SUS, copper, copper alloy, or titanium on a spool with a plate thickness of 0.15 mm or less.
[0002]
[Prior art]
For example, when winding a metal foil such as KS (soft steel) having a plate thickness of 0.15 mm or less used for a shadow mask, FPC or the like onto a spool, as shown in FIG. There is a method of fixing the winding start end 1A to the spool surface with the filament tape 2.
[0003]
However, in this method, a so-called “wrap mark” or “end mark” is formed in which the metal foil is folded into the shape of the tape at the position where the filament tape 2 is applied from the second roll to around the 550th roll. The problem is that the yield is poor.
[0004]
Therefore, instead of using a filament tape, conventionally, spray paste is applied to the contact surface of the winding start end 1A of the metal foil 1 with the spool 100 and directly applied to the spool.
[0005]
However, even in this method, there is a problem that the yield is poor because the metal foil 1 is folded at the step position of the winding start end 1A from the second roll to around the 300th roll due to the step at the winding start end 1A.
[0006]
[Problems to be solved by the invention]
Therefore, as shown in FIG. 5, the present inventor, when winding a mild steel foil 1 having a thickness of 0.05 mm and a width of 520 mm around a spool 100 having a diameter of 500 mm, causes a step generated at the winding start end 1 </ b> A of the metal foil 1. In order to eliminate this, an attempt was made to apply 4 to 6 g of heat-resistant grease 3 over a predetermined distance (L) from the winding start end 1A, for example, 1 to 10 mm. As the grease 3, OMEGA MANUFACTURING DIVISION (product name: 99) was used.
[0007]
By this method, the folding of the metal foil 1 was significantly reduced, but did not become zero. It was also found that there is a difficulty in standardizing the grease application work, for example, the effect of preventing the metal foil from being broken is halved only by slightly changing the position where the grease 3 is applied.
[0008]
Accordingly, an object of the present invention is to provide a metal foil winding method capable of winding a metal foil having a thickness of 0.15 mm or less onto a spool very easily and without being damaged. is there.

[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the method for winding a metal foil according to the present invention will be described in more detail with reference to the drawings.
[0017]
According to the present invention, as illustrated in FIGS. 1 and 2, first, the winding start end 1 </ b> A of the metal foil 1 is attached to the surface of the spool 100. The metal foil 1 used in the present invention generally has a plate thickness (t) of 0.15 mm or less, 0.005 mm or more, usually 0.10 mm or less, 0.009 mm or more, and a width (W) of 100 to 1000 mm. are, for example, refers to mild steel, Invar, SUS, copper, copper alloy, or a metal foil of titanium.
[0018]
According to this embodiment, the spray paste 5 is applied to the spool surface with which the winding start end 1A of the metal foil 1 contacts, and the metal foil 1 is applied to the spool 100 over a distance L0 from the end surface of the winding start end 1A of the metal foil 1. Affixed directly. As spray paste 5, Konishi Co., Ltd. (product name: Z-2) used conventionally was used. When such a spray paste 5 is used, the distance LO for attaching the metal foil 1 to the spool 100 is usually 100 to 300 mm.
[0019]
Next, according to the present invention, the elastic band 11 is adhered to the spool surface by the adhesive 12 over a predetermined distance (L), usually 5 to 50 mm, from the winding start end 1A of the metal foil 1 to the downstream side in the spool rotation direction. Is done. In this embodiment, the length (L) of the belt-like elastic body 11 in the spool rotation direction is 20 to 25 mm, and the length of the belt-like elastic body 11 in the spool axis direction, that is, the width (W) is It is the same as the width (w) of the metal foil 1 to be wound, or is increased by 5 to 10 mm. Further, the thickness (T) of the belt-like elastic body 11 varies depending on the thickness (t) of the metal foil 1 wound around the spool 100, but is usually in the range of 1 to 5 mm.
[0020]
As the belt-like elastic body 11, a foamed plastic sheet such as foamed polyurethane, foamed polyethylene, foamed polystyrene, foamed polyvinyl chloride, foamed epoxy resin, foamed cellulose acetate or the like can be used. Further, as the adhesive 12, any foam adhesive can be used as long as the elastic band 11 can be temporarily attached to the surface of the spool 100. For example, an acrylic adhesive can be used. It can be preferably used.
[0021]
In this embodiment, in order to improve workability, as shown in FIG. 3, the belt-like elastic body 11 and the adhesive 12 are integrated, and further, the release layer is attached to the adhesive layer 12 to improve the handleability. Thus, the elastic tape 10 can be formed as a single unit by attaching 13. As such an elastic tape 10, for example, an elastic tape (product name: 40H-2 gray) manufactured by SanM Kasei Co., Ltd. can be used.
[0022]
The structure of the tape will be briefly described with reference to FIG. 3. The belt-like elastic body 11 is an ester foam (trade name: Soflan # 430), and the physical properties are as shown in Table 1.
[0023]
[Table 1]

[0024]
As the adhesive 12, an acrylic pressure-sensitive adhesive that is a two-component curing agent that is a pressure-sensitive adhesive for foam is used. At this time, the curing agent is used at a ratio of 260 g with respect to 15 kg of the main agent. The properties are as shown in Table 2.
[0025]
[Table 2]

[0026]
In the elastic tape 10, the belt-like elastic body 11 has a thickness (T) of 2 mm and a width (L) of 20 mm, and the adhesive layer 12 has a thickness (T1) of 0.03 mm (coating amount 50 to 80 g / m 2), and a release paper 13 as a release material having a thickness (T 2) of 0.09 mm is attached to the adhesive layer 12.
[0027]
Accordingly, when the elastic tape 10 is used, first, the tape 10 is cut to a predetermined length, then the release paper 13 is peeled off, and the belt-like elastic body 11 is pasted on the spool 100 as shown in FIG. The metal foil 1 is attached to the spool surface along the end surface of the winding start end 1A. Of course, after the belt-like elastic body 11 is stuck to the spool 100, the winding start end 1A of the metal foil 1 may be stuck to the spool surface along the end surface of the belt-like elastic body 11.
[0028]
Thereafter, the metal foil 1 is wound around the spool 100 by rotating the spool 100.
[0029]
According to the results of experiments conducted by the present inventor, a mild steel foil having a thickness (t) of 0.05 mm and a width (w) of 520 mm was wound on a spool 100 having a diameter of 500 mm according to the above procedure. Did not occur at all.
[0030]
Moreover, standardization of the affixing operation | work of the strip | belt-shaped elastic body 11 or the elastic body tape 10 was also able to be implemented easily.
[0031]
