PURPOSE:To prevent joined part from being conspicuous by damage for the planeness of a screen surface with an uneven shape near a joined part by abutting the cutting surfaces of sheets as a joint surface and interposing an adhesive only on this joint surface to adhe them. CONSTITUTION:The cut surfaces of two screen sheets 1 and 1' are exactly abutted as joint surfaces 2 and 2' and temporarily fixed by attaching a first auxiliary tape 4 to a joint part 3 on the back side of the screen sheet. Next, a water-soluble adhesive 6 with high viscosity is applied on a joint part 5 on the front side of the screen sheets 1 and 1' and the water-soluble adhesive 6 is covered with a second auxiliary tape 7. Thus, even when the screens 1 and 1' are spread by applying strong force, the joint parts are not made uneven and opened and further, the instantaneous adhesive agent 6 is not protruded from the joint part 5. Then, the joined part is inconspicuous. |
