According to the high growth of industry and the development of polymer chemical industry, adhesive products for various uses have been developed. Especially, when the adherend is an organism, it is desirable to consider not to disturb the respiration of the organism besides the basic performance as an adhesive. As it is coated in the form of a film in the product, the air permeability is extremely inhibited, which may cause respiratory problems.

In order to solve such a problem, a method of forming an unevenness on the roller to prevent the adhesive from being applied partially or removing the adhesive by contacting a steel wire, etc. has been developed. As the defect is formed, the applied adhesive has an orientation and adversely affects the adhesive force, which is a basic function of the adhesive product. (If the adhesive has directionality in the longitudinal direction, the adhesive has a stable adhesive force in the longitudinal direction, but greatly decreases the adhesive force in the width direction. Was easily removed) there was a problem.

The present applicant has made various attempts to overcome the above-mentioned problems.
