Description

A kind of double-sided adhesive composite mechanism and its composite method

technical field

The invention relates to a double-sided adhesive composite mechanism and a composite method thereof, belonging to the technical field of double-sided adhesive processing.

Background technique

The double-sided adhesive for medical use includes adhesive layer and isolation layer. The isolation layer adopts release paper. There are certain requirements for the width of the adhesive layer and release paper. It is required to leave a certain distance between the left and right sides of the adhesive layer, that is The width of the adhesive layer is slightly larger than that of the release paper when it is not cut. In the existing production process, in order to make the width of the release paper and the adhesive layer the same, the redundant cutting knife is cut off on the equipment. When the cutter is cutting the glue layer, that is, when the knife is cutting the glue layer, it is easy to stick to the glue layer. Because the distance between the glue layer and the edge of the type paper is too small, it will cause the distance control of the cutter during the process of cutting off the excess glue layer. Not good, and easy to cut.

In view of this, the applicant conducted special research on this, and developed a double-sided adhesive compound mechanism and its compound method, and this case arose from it.

As preferably, also include the following steps:

Step (4) Rewinding: Rewind the new composite double-sided adhesive tape and coating layer obtained in step (3) respectively.

Preferably, the coating layer uses a release material.

The present invention can realize following technical effect:

(1) On the basis of obtaining the release paper of the same width and the double-sided adhesive of the double-sided adhesive layer, the composite mechanism and its composite method can save the cost of cutting the redundant adhesive layer in the traditional process, Improve production efficiency and product quality;

(2) The double-sided adhesive layer can be compounded with different release materials to meet product diversification.
