Embodiment Construction
[0014] Such as figure 1 As shown, in the fixing method of the present invention, the thickness of the metal foil should be less than or equal to 20 microns, and when fixed between the winding sleeve 1 and the metal foil 2,
[0015] In the first step, a layer of rolling oil is attached to the inner surface of the metal foil 2 and the winding sleeve 1;
[0016] In the second step, the flat end of the metal foil material 2 is cut into a 30°~60° oblique shape;
[0017] In the third step, the metal foil material 2 is directly attached to the outer surface of the winding sleeve 1 by using the rolling oil attached to the surface of the metal foil material 2 .
[0018] The fourth step is to turn on the winding machine and drive the winding sleeve 1 to rotate 3 to 5 times along the winding direction of the metal foil material 2. At this time, the metal foil material 2 does not rotate with the winding sleeve 1;
[0019] In the fifth step, during the independent rotation of the winding...
