A device for working of material plates (1), such as glass panes, has a supporting means (25, 26, 29) for the material plate (1) and a tool (12, 18) for working the material plates (1). The supporting means (25, 26, 29) has paired supporting elements (25', 25", 26', 26", 29', 29") with supporting surfaces (27', 27", 30', 30") facing one another, between which the material plate (1) is held. There are openings (31) for liquid emerging under pressure in the supporting surfaces (27', 27", 30', 30"). The material plate (1), especially the glass pane, is therefore not mechanically supported, as is conventional in the prior art, but uses a liquid film which is formed under pressure in the gap between the material plate (1) and the supporting surfaces (27', 27", 30', 30") of the supporting elements (25', 25", 26', 26", 29', 29").
L'invention concerne un système pour travailler des plaques de matière (1), telles que des feuilles de verre, ce système comprenant un dispositif de support (25, 26, 29) destiné à supporter une plaque de matière (1), ainsi qu'un outil (12, 18) servant à travailler les plaques de matière (1). Ledit dispositif de support (25, 26, 29) comprend des éléments de support (25', 25", 26', 26", 29', 29") allant par paire, ces éléments présentant des surfaces de support (27', 27", 30', 30") qui se font face et entre lesquelles une plaque de matière (1) peut être maintenue. Des ouvertures (31) sont ménagées dans ces surfaces de support (27', 27", 30', 30") pour permettre le passage d'un liquide sortant sous pression. Contrairement à la technique antérieure, la plaque de matière (1), en particulier la feuille de verre, n'est pas supportée de façon mécanique mais au moyen d'une pellicule de liquide qui est formée sous pression dans l'interstice situé entre la plaque de matière (1) et les surfaces de support (27', 27", 30', 30") des éléments de support (25', 25", 26', 26", 29', 29").
