Problems solved by technology

However, due to the small thickness of the foil material, when the foil material is pasted on the sleeve with double-sided adhesive tape, the material roll will bulge due to the protrusion of the tape; and during the winding process, the foil material is easily discounted due to its poor shape. resulting in the failure of rolling

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...

Abstract

The invention discloses a method for fixing an end of metal foil and a steel sleeve. The thickness of the metal foil is smaller than or equal to 20 micrometers; when the steel sleeve and the metal foil are fixed, in the step one, a layer of rolling oil is attached to the inner side surface, fit with the steel sleeve, of the metal foil. With the adoption of the method, bulging and folded phenomena which areextremely liable to occur in the process that the end of the metal foil with the thickness smaller than or equal to 20 micrometers winds around the steel sleeve during rolling are eliminated, and the metal foil with the thickness smaller than or equal to 20 micrometers can wind around the middle of the steel sleeve quickly and flatly without adhesive tapes during rolling, so that rolling production of the foil can be started quickly.

Description

technical field [0001] The invention relates to a method for fixing an end part of a metal foil material and a steel sleeve during rolling. Background technique [0002] Before metal foil rolling, it is necessary to pass the foil through the foil from the uncoiling side of rolling to the winding side, and then paste the end of the foil to the middle position of the winding sleeve on the winding side, and turn on the winding machine The foil is wound flat and tightly around the take-up sleeve and rolling begins. However, due to the small thickness of the foil material, when the foil material is pasted on the sleeve with double-sided adhesive tape, the material roll will bulge due to the protrusion of the tape; and during the winding process, the foil material is easily discounted due to its poor shape. As a result, rolling cannot be carried out. Contents of the invention [0003] The purpose of the present invention is to provide a fixing method between the end of the met...
