保持する必要がある。2. Prior Art Conventionally, the method for manufacturing this type of smooth coating film (for example, ``Practical Comprehensive Data Collection of Dispersion Technology and Industrial Applications JP762, Business Development Center Publishing Department'') has been a process as shown in FIG. 2. In other words, it can be seen in part of the manufacturing process of magnetic recording media such as magnetic tapes.After dust removal, magnetic powder and vehicle are mixed and dispersed on the paste, a magnetic paint is applied which is passed through the mouth, and after being oriented in a magnetic field and dried, A smooth coating film of magnetic material is formed by surface treatment.The surface treatment process is one of the factors that determines the characteristics of a magnetic recording medium, and it is necessary to maintain stable surface smoothness.

いた。従って平滑塗膜を安定して得ることができにくい
という問題点を有していた。Problems to be Solved by the Invention However, in the manufacturing process as described above, when magnetic recording media are continuously produced, the magnetic layer adheres to the surface treatment roll. Furthermore, continuous production generates heat in the surface treatment roll, causing the roll to warp in the longitudinal direction, resulting in uneven surface treatment, resulting in variations in product characteristics and hindering production. Therefore, there was a problem in that it was difficult to stably obtain a smooth coating film.

転写するものである。Means for Solving the Problems In order to achieve the above object, the present invention provides a coating film formed on a smooth first sheet whose surface has been subjected to a mold release treatment, and the surface of the coating film is coated with an adhesive. The coating film is transferred onto the second sheet by stacking the two sheets together so as to contact the adhesive surface of the second sheet and feeding the two sheets between two pressure rolls having parallel axes.

In FIG. 1, reference numeral 1 denotes a smooth sheet whose surface has been subjected to mold release treatment, and a coating film 2 is formed on the surface of the smooth sheet 1. 3 is a sheet on which the coating film 2 is formed. Reference numeral 4 denotes an adhesive supply unit that joins the sheet 3 and the coating film 2, and gradually supplies adhesive to one side of the sheet 3 as the sheet 3 moves. 5 is smooth sheet 1
6 is two pressure rolls having parallel axes, and 7 is a roll around which the sheet 3 is wound.

In FIG. 1, first, a smooth sheet 1 is unwound from a roll 5 and fed between pressure rolls 6. At this time, the coating film 2 is placed on the side in contact with the sheet 3. On the other hand, the sheet 3 is unwound from the roll 7, an adhesive is applied to the adhesive surface of the coating film 2 in the adhesive supply section 4, and the sheet 3 is sent to the pressure roll 6 together with the smooth sheet 1. In the pressure roll θ, the adhesive coated surface of the sheet 3 and the coating film 2 of the smooth sheet 1 come into contact and are pressurized, so that the coating film 2 separates from the smooth sheet 1 and adheres to the sheet 3. When it leaves the pressure roll 6, a smooth coating film 2 is formed on the 7-toe 3,
The smooth sheet 1 is sent without the coating film 2. In this way, the coating film 2 is transferred onto the sheet 3, and a coating film having a smooth surface can be easily obtained.
