摘要： A cathode ray tube fixturing device for position a face panel and a funnel during a frit sealing process. The device includes a cone holder for positioning a constricted portion of the funnel, and a movable abutting block which is adapted to abut against the panel and the funnel. A pivoting arm connects the cone holder with the movable abutting block, and at least one fixed abutting block is adapted to abut against the panel and the funnel and is located in opposed relationship with respect to the movable abutting block. When the funnel and the panel are mounted in the cone holder in assembled relation, their common centerline is vertical. In this assembled relation, the panel and funnel are urged against the fixed abutting block by the movable abutting block so that the seal from the panel to the funnel can be effectively produced and the fixturing device is reduced in weight.
