を形成している。(Prior art) The purpose is to improve the durability of the panel surface such as weather resistance, water resistance, abrasion resistance, etc., to add decorative properties to the surface, and to prevent dazzling caused by light reflected from the surface. Therefore, the applicant proposed a bead-coated sheet for adhering to the surface of a panel in Utility Application No. 31594 of 1988. The bead coated sheet is a flexible sheet l as shown in FIG.
An adhesive layer 2 is formed on the surface of the adhesive layer 2, and countless transparent beads 3 are attached to the adhesive layer 2 to form beads N4. Conventionally, bead-coated sheets are produced by dropping and scattering beads onto an adhesive layer 2 applied to a flexible sheet 1, collecting unattached excess beads after the adhesive hardens, and forming a single-layer bead layer 4.

(Means for Solving the Problems) In order to achieve the above object, the manufacturing method of the present invention is such that numerous transparent beads 3 are attached to an adhesive layer 2 formed on the surface of a flexible seam. In this method, a grid 12 is provided facing above a flat container 11 containing beads 3, and a flexible sheet 1 is placed above the grid 12 with an adhesive layer 2 facing each other. Then, a high voltage 14 is applied using the flat container 11 and the grid 12 as electrodes, and the beads 3 in the flat container 11 are attracted to the grid 12 and allowed to pass through the gaps between the grids 12 and adhere to the adhesive layer 2. This is a precept for invention.

ズが接着面に均一に付着される。(Function) When a high voltage is applied to the flat container and the grid, an electric field with a large potential gradient is generated between the two. On the other hand, the beads on the flat plate are each charged with the same sign as the electrode on the flat plate and are attracted toward the grid. Most of the suctioned beads pass through the gaps in the grid, fly towards the adhesive layer of the flexible sheet placed above and opposite to the grid, and adhere to and become embedded in the same layer. At this time, since the beads that have not reached the adhesive surface fall downward, the beads are uniformly attached to the adhesive surface without interfering with the attachment of newly flying beads to the adhesive surface.

Furthermore, the amount of beads attached can be easily controlled by adjusting the application time.
