ABSTRACT:
A device for fixing and maintaining a shapeable glass plate (1) in position during its machining. The plate (1) is placed on a support surface (2) and preferably maintained spaced therefrom to allow a usual operating tool to move and act thereon, for example during a chamfering process. The device includes a plurality of suckers (11) associated with at least two mutually independent support elements (3, 3A, 3B) interposed between the plate and the support surface, the suckers (11) being associated with opposing faces (9, 10) of each element (3, 3A, 3B) so as to cooperate with the plate (1) and surface (2) respectively, the elements being constrained directly to each other but movable relative to each other and including air passage conduits (15, 16, 20, 55, 56) which, by drawing air from one element to another by suction applied to an opening (17, 18) at which at least one of the conduits opens to the outside of one of the elements, removes air from all the suckers (11) to constrain them to the plate (1) and support surface (2), so fixing these latter together.
