Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of die cutting, in particular to a processing method of double-sided adhesive tape product with narrow adhesive strip. BACKGROUND

[0002] Double-sided adhesive tape is a roll-shaped adhesive tape made of paper, cloth or plastic film as base material, and elastic body type pressure sensitive adhesive or resin type pressure sensitive adhesive uniformly coated on the base material. It is composed of three parts of base material, adhesive and release paper (film). The adhesive tape can stick things because a layer of adhesive is coated on its surface. The earliest adhesive came from animals and plants. In the nineteenth century, rubber was the main component of adhesive. In modern times, various polymers are widely used. The adhesive can stick things because the molecules form a bond with the molecules of the object to be connected, which can firmly bond the molecules together. There are many types of double-sided adhesive tape: grid double-sided adhesive tape, reinforced double-sided adhesive tape, Rubber double-sided adhesive tape, high temperature double-sided adhesive tape, non-woven fabric double-sided adhesive tape, no residue double-sided adhesive tape, cotton paper double-sided adhesive tape, double-sided glass cloth adhesive tape, PET double-sided adhesive tape, foam double-sided adhesive tape, etc. It is applied to the production process of various industries.

[0003] With the technological innovation, the functions of electronic products are increasing, and the requirements for parts are also increasing. The size of double-sided adhesive tape used for auxiliary sticking is becoming smaller and smaller, and the processing requirements of the die cutting machine are also increasing. Figures 1-7 The processing method of a certain double-sided adhesive tape product in the prior art is as follows: Figure 1 The middle shaded area is the double-sided adhesive area, and the width is only 0.5mm; Figure 4 The double-sided adhesive tape in the double shaded area is the reserved area of the final double-sided adhesive tape, and the single shaded area is the waste area to be discarded. Since the area of the waste area is about 4 times larger than that of the reserved area, the double-sided adhesive tape in the reserved area is easily dropped during the material collection, resulting in a lack of material in the final product and scrap.

[0004] Therefore, it is very important to provide a processing method for reducing the lack of material in the final product. SUMMARY

[0005] In order to solve the above problems, the purpose of the present application is to provide a processing method of double-sided adhesive tape product with narrow adhesive strip.
