A machine for cutting a plate of laminated glass, comprising: - a main conveying surface for conveying the plate of laminated glass and the portions (G1, G2) cut therefrom, provided with means for feeding the plate or portions of plate (G1, G2) thereon in a longitudinal direction of the machine; - at least one cutting bridge set in a fixed position over the conveying surface and oriented crosswise with respect to said longitudinal direction, for carrying out operations of cutting of the plate along a cutting line (p 1) of the machine, transverse with respect to said longitudinal direction; and - at least one device for imparting a rotation of 90° in the horizontal plane on a portion of plate in the form of cross-cut portion or in the form of cross-cut subportion (T1a, T1b, T1c, T1d), after it has been obtained by means of a cutting operation at the cutting bridge, so that said cross-cut portion or cross-cut subportion (T1a, T1b, T1c, T1d) can in turn be further divided into subportions, - a second cutting bridge set downstream of the first cutting bridge, and - a waiting section situated between the first and second cutting bridges (P1, P2), so that said waiting section is able to accumulate a plurality of portions of plate, characterized in that said waiting section comprises: - a rack having a plurality of shelves set on top of one another and apart from one another, which can be displaced vertically to bring any one of the shelves of the rack to the level of the main conveying surface so that said waiting section is able to accumulate a plurality of portions of plate (G1, G2) on said shelves set on top of one another and at a distance apart; and - said rack comprises auxiliary conveying means provided on board one or more of said rack shelves to bring about longitudinal advance of the portions of plate (G1, G2) set on top of said rack shelves. - a main conveying surface for conveying the plate of laminated glass and the portions (G1, G2) cut therefrom, provided with means for feeding the plate or portions of plate (G1, G2) thereon in a longitudinal direction of the machine; - at least one cutting bridge set in a fixed position over the conveying surface and oriented crosswise with respect to said longitudinal direction, for carrying out operations of cutting of the plate along a cutting line (p 1) of the machine, transverse with respect to said longitudinal direction; and - at least one device for imparting a rotation of 90° in the horizontal plane on a portion of plate in the form of cross-cut portion or in the form of cross-cut subportion (T1a, T1b, T1c, T1d), after it has been obtained by means of a cutting operation at the cutting bridge, so that said cross-cut portion or cross-cut subportion (T1a, T1b, T1c, T1d) can in turn be further divided into subportions, - a second cutting bridge set downstream of the first cutting bridge, and - a waiting section situated between the first and second cutting bridges (P1, P2), so that said waiting section is able to accumulate a plurality of portions of plate, - a rack having a plurality of shelves set on top of one another and apart from one another, which can be displaced vertically to bring any one of the shelves of the rack to the level of the main conveying surface so that said waiting section is able to accumulate a plurality of portions of plate (G1, G2) on said shelves set on top of one another and at a distance apart; and - said rack comprises auxiliary conveying means provided on board one or more of said rack shelves to bring about longitudinal advance of the portions of plate (G1, G2) set on top of said rack shelves.
