Abstract

PURPOSE:To eliminate the entrainment of air between an adhesive sheet and the thin film surface of a base and allow uniform adhesion and peeling-off by permitting the adhesive surface of an adhesive sheet to come in contact with the thin film surface of the main body of a base with a thin film using rotary adhesion technique and peeling the adhesive surface off the other, printing the thin film. CONSTITUTION:A feed roll 2 consisting of long base sheet 1 with a thin film (a) made up of an adhesive film a1 part and an easily peeling-apart thin film a2 part formed in a wound roll shape, is provided on a roll shaft 2a. In addition, a feed roll 6 consisting of an adhesive sheet 9 with an adhesive layer (b) formed in a wound roll shape, is provided on a roll shaft 6a. Then the adhesive layer(b) surface of the adhesive sheet 9 guided by a roll 8 is hardened using an air cylinder and caused to come in contact with a stamping roll 5 under pressure. Next, a winding roll 3, a guide roll 4, the stamping roll 5 and a winding roll 7 are interlocked through a drive belt using a drive mechanism. Consequently, the easily peeling-apart film a2 of the thin film(a) sticks to the surface of the thin film(a) of the adhesive sheet 9, then the easily peeling- apart film peels off the base sheet 1 and only the adhesive film a1 part remains on the surface of the base sheet.

(Prior art) As a method for peeling off only the easily peelable area as an unnecessary part from a thin film consisting of an adhesive thin film area and an easily peelable thin film area on a base material, A chemical peeling method is used, or a pressure-sensitive adhesive sheet with a sticky adhesive layer is temporarily attached to the front surface of the thin film, and then the pressure-sensitive adhesive sheet is peeled off to remove only the easily peelable area from the substrate surface. There is a physical peeling method. In this physical peeling method, as shown in FIG. Paste the sheet b on the entire surface, then (c) peel off the adhesive sheet b and remove the easily peelable film a from one side of the base material.
By peeling off only two areas, (2) an image pattern consisting of only one area of the adhesive 11Aa is formed on the base material 1.

In the physical peeling method described above, a cutting operation is required to cut the adhesive sheet b according to the size of the base material 1, and care must be taken to avoid trapping air in the adhesive sheet b over the entire surface of the base material. It is necessary to apply it evenly while brushing the
Moreover, peeling off of the adhesive sheet b after pasting is performed by manual operation. In addition, if you want to express a continuous pattern, if the base material is large, or if you want to transfer the product to the next process in a long roll, roll it instead of cutting it into single sheets. The peeling must be completed in a similar manner. Therefore, the peeling process took time and effort. In addition, due to manual operation, the adhesive pressure and peeling speed of the adhesive sheet to the base material are not constant and unstable, so it has been rarely desired to achieve a stable quality finish.

(Operation of the Invention) According to the present invention, the adhesive surface of the adhesive sheet is brought into contact with the thin film formed on the base material, which is formed by an adhesive film area and an easily peelable area, in a rotary manner, using a stamping mechanism. While gradually rotating the stamping mechanism, the adhesive sheet is simultaneously pulled out in different directions, and the easily peelable film region can be transferred from the base material surface to the adhesive surface side of the adhesive sheet and peeled off. There is no air entrapment between the pressure-sensitive adhesive sheet and the thin film surface of the base material, as is the case with conventional methods, and uniform adhesion and peeling can be achieved.
