なる等の問題が多かった。However, all of the above conventional methods require a laminating machine, and in the method of applying adhesive to both sides of the laminate and core base material, the adhesive adheres to the laminating press member of the laminating machine. Therefore, special measures are required to prevent this, and in the method of applying adhesive to two release sheets and then transferring it to the core substrate, it is necessary to wind up one release sheet. Even if the release sheet is used repeatedly, there are many problems such as a large number of steps, poor workability, and high costs, such as the need to reapply the release agent as the release agent deteriorates. .

る。[Means for Solving the Problems] In the method and apparatus for manufacturing a double-sided adhesive tape according to the present invention, as a means for solving the above problems, adhesive is applied to both sides of a release sheet coated with a release agent on both sides. A method is used in which the release sheet and a separately supplied core base material are applied with a certain tension by a drive roll, and then wound up by a product winding means. Further, the apparatus for implementing the method includes a release paper supplying means, two adhesive application means for applying adhesive to both sides of the release sheet, a core base material supplying means,
It is comprised of one drive roll to apply a constant tension to the release sheet coated with the adhesive and the core base material at all times, and a product winding means with a winding rotation speed adjusting means.

This allows the product to be wound up with approximately the same winding force when the winding diameter is small or large, and it is also possible to apply a uniform layer of adhesive on both sides of the core base material. It is possible to produce a durable double-sided adhesive tape.
