It is necessary to wind up. Therefore, complicated control is required, but accurate control is difficult. Even if the tip of the metal band is at the predetermined position at the start of winding, the rubber sleeve and the coil slide during winding, and the position of the tip of the metal band deviates from the predetermined position, preventing the top mark. It often disappears.

とを特徴とする金属帯の巻取り方法。The present inventor notices that when a metal strip is wound around a coil by a reel, the first one is naturally scraped due to scratches and the like, and the second metal is wound before the start of winding. It is possible to reduce the step by forming a recess in the metal band that the tip of the band hits beforehand and inserting the metal band tip into the recess at the time of winding to wind up, and to prevent the occurrence of top marks. Upon finding out, the present invention has been completed. The gist is "a method of winding a metal strip around a reel in a coil shape. When the metal strip is wound around the reel, the metal strip is attached to the metal strip where the tip of the metal strip overlaps with the second metal strip. It is characterized in that a recess into which the front end of the metal band can be inserted is formed in advance in a state where the band is wound around the reel, and the front end of the metal band is inserted into the recess at the time of winding to wind the metal band. In the winding method of the metal strip to be, and in the winding method of this metal strip, the recess gradually becomes shallower from the deepest portion toward the rear end of the metal strip,
A method of winding a metal strip, which has a shape satisfying the following formulas (1) and (2).

り前に窪みを設けておく。Since the top mark is generated due to the step 7 as shown in FIG. 3, in the present invention, in order to make the step as small as possible, a portion where the tip of the metal strip hits the second metal strip, That is, a recess is provided in the part P of FIG. 3 before winding.
【００１５】ここで、部位とは金属帯の先端が２巻目の
金属帯に重なる部分のみを指すのでなく近傍を意味す
る。Here, the part means not only the portion where the tip of the metal strip overlaps the second metal strip, but also the vicinity thereof.

ることはないからである。The depression must be such that the tip of the metal strip can be inserted with the metal strip wound around the reel. For that purpose, it is necessary to provide a recess of a predetermined size in the vicinity of P in FIG. That is,
A recess having a predetermined length (thick line in FIG. 3) from the P portion toward the rear end of the metal strip must be formed. This is because even if a deep recess is provided only at the point P, the metal strip is wound up by a gently curved reel, and therefore only the tip of the metal strip is not bent and inserted into the recess.
【００１７】このような方法により金属帯をリールに巻
き取る場合、二巻目になるとき金属帯の先端部は窪みに
挿入され、段差は窪みに吸収され小さくなり、トップマ
ークの発生を防ぐことができるのである。When the metal strip is wound on the reel by such a method, the leading end of the metal strip is inserted into the recess when the second roll is made, and the step is absorbed by the recess and becomes small, thereby preventing the occurrence of the top mark. Can be done.

図３に比べ極めて小さくなっている。FIG. 4 is an example showing a state in which a metal band is wound on a reel by the method of the present invention. In this example, a recess is formed in which the depth gradually decreases from the position where the front end 4 of the metal band abuts to the rear end of the metal band. As shown in FIG. 4, the tip portion of the metal strip enters the depression, and the step 7 is extremely smaller than that in FIG. 3 in which the depression is not provided.

確に窪みに入る。FIG. 2 is a side view showing an example of the shape of the depression. FIG. 3A shows a shape in which the depth gradually decreases from the deepest portion h of the depression toward the rear end of the metal strip, and the tip of the metal strip enters the deepest portion h. In the shape of FIG. 7C, the bottom of the recess is tapered and shallower from the deepest portion toward the tip direction as compared with the shape of FIG. The diameter of the reel is usually constant, the position of the metal band at the tip of the metal band when winding is the type of metal band,
It is constant regardless of the size at the position of the circumference of the reel (reel diameter x π) from the tip of the metal strip. Therefore, if a recess is provided at a fixed position of the metal strip, the tip of the metal strip will enter the recess accurately during winding.

のが（ｄ）である。If, for some reason, the tip of the metal strip is displaced from the position where it abuts against the metal strip, the tip of the metal strip is likely to enter the recess if the shape as shown in (c) is used. Furthermore, the shapes of (b) and (c) make it easier for the tip of the metal band to enter the depression. Further, by designing the deepest part of the depression to be long, the tip of the metal strip is surely located at the deepest part of the depression (d).
【００２２】どの形状の窪みにしても、段差を最小にす

の厚さｔの７０％以上の深さとするのが好ましい。When the depth of the deepest part of the depression is h and the length of the depression in the lengthwise direction of the metal strip is a, it is preferable that the depth h is large in order to absorb the step difference at the tip of the metal strip. However, if the recess depth h is made too large, the metal strip may break at the deepest part, so it is desirable to set it to 95% or less of the plate thickness t. Further, if it is too shallow, the step becomes large, so it is preferable to set the depth to 70% or more of the thickness t of the metal band.
