Abstract
The machine includes a frame (11) and a film (12) for one of two substrates (1, 2) to be pressed onto the other under a plate (4). It is then possible to polymerize by points a glue joint (3) so as to assemble the two substrates. Accurate displacement means (7, 8, 9, 10) and observation means (13, 14, 15) are also provided. Application for the embodiment of liquid crystal cells.
