And a robot for moving the adhesive jig, and a robot for moving the adhesive jig.

[0010]

According to the first means, the continuous conductive sheet plate is sent by peeling off the release paper by winding the release paper, and is bonded to the continuous protective paper which is being sent out at the same time. Sent to the club. The conductive sheet plate and the protective paper which are bonded and continuous are cut into a predetermined size by a cutter. The sheet piece composed of the cut conductive sheet plate and the protective paper is attached between the face surface of the cathode ray tube and the reinforcing metal member by an attaching means.

By configuring the attaching means like the second means, the sheet piece cut by the cutter portion as described above is adsorbed and held by the adsorption plate and pressed against the face surface and the reinforcing metal fitting, and then the sheet is attached. The piece is pressed against the step portion between the face surface and the reinforcing metal fitting with the corner pressing roller, and finally the entire sheet piece is adhered along the face surface and the reinforcing metal fitting with the copying roller.
