An apparatus for setting a gap of a glass panel (W) having two glass substrates (20, 21) is disclosed. It includes an annular spacer (12) for surrounding the glass panel (W), a supporting plate (11) for supporting the glass panel and the annular spacer, the width of the supporting plate being greater than that of the annular spacer, a pair of opposing columns (2, 2A) for receiving the supporting plate (11), a flexible sheet (14) disposed on the annular spaces, the width of the sheet being greater than that of the annular spacer so as to be associated with the supporting plate to enclose the glass panel, means (13, 15, 16) for defining a closed space between the supporting plate (11) and the flexible sheet (14), a passage (8) in fluid communication with the closed space, and means (9) connected to the passage for evacuating the closed space.
