Abstract
A process is disclosed for positioning spacer beads on a plate of a flat display screen formed by two adjacent plates constituting a flat air-tight chamber. The method includes providing a hollow needle mounted on a mobile head which is connected to a vacuum/overpressure system. The hollow needle sucks a bead from a bead tank, applies the bead onto a plate covered with an adhesive material to adhere adhesive onto a section of the bead, then removes the bead from the plate. Finally, the needle deposits the bead onto one of the two adjacent plates.
