Furthermore, generally in the final step, in the completed winding core by winding the surface tape (5), the edge of the surface tape (5) tends to rise, a so-called selvage phenomenon. When wrapping the front tape (5), the front tape (5) absorbs moisture from the adhesive applied to the back side and expands, causing the length of the back side to be longer than the length of the front side. This is caused by the curling of both edges, which are then bonded together.

In addition, in FIGS. 1 and 2, the edges (5a) (5b) of the surface tape (5) are illustrated as having become thinner due to pressure, but the thickness is limited to the form shown in the figures. In general, a relatively thick material is used for the inner surface material of the inner surface N (3), and the inner surface layer (3) is used for the surface tape (5).
I tend to use thinner ones. As a result, depending on the material selected, the thickness of the surface tape (5) may not change after pressing, and the inner surface material may be depressed by the thickness of the surface tape (5).

In addition, in the example, the surface tape (5) is wrapped heavily,
Although the surface layer is made up of layers, the present invention is not limited to this. For example, the surface tape (5) may be wrapped twice or more to form a surface layer (4) made of multiple layers.

The pressing process may be applied to each layer of the plurality of layers, but it is also possible to press only the overlapping edges of the outermost surface tape (5), thereby preventing the above-mentioned blank area. can. It should be noted that each layer of the plurality of layers may be formed using the same material or different materials.
