A method for providing laminated glass panes (1, 2, 3, 4) starting from a sheet of laminated glass which comprises a cutting and separation phase in which said sheet is scored or scored and separated multiple times in sequence along a fixed cutting axis of a cutting machine and is moved with respect to said fixed cutting axis so as to cut said glass panes (1, 2, 3, 4), which are separated from the rest of said sheet, said cutting and separation phase comprises: - a preliminary step for the cutting and separation of the transverse portion, in which said sheet is cut from one edge to an opposite edge so as to obtain a transverse portion which is separated from the rest of the sheet, said transverse portion being constituted by a longitudinal portion of said sheet; characterised in: - a first scoring step, in which multiple first mutually parallel score lines (11, 12, 13) are performed, translating the transverse portion with respect to said fixed cutting axis following each one of said first score lines (11, 12, 13), followed by - a second rotation step, in which the transverse portion is rotated through 90° with respect to said cutting axis, followed by - a third step of scoring and separation, in which multiple second score lines (21, 22, 23) are performed which are parallel to each other and perpendicular to said first score lines (11, 12, 13), translating the transverse portion with respect to said fixed cutting axis following each one of said second score lines (21, 22, 23); each one of said second score lines (21, 22, 23) intersecting at least one of said first score lines (11, 12, 13) so as to define a plurality of rectangular panes (1, 2, 3, 4); following each one of said second score lines (21, 22, 23), an outermost rectangular pane (1, 2, 3, 4) being separated from the rest of the transverse portion together with a corresponding waste (91, 92, 93) which is not separated from said rectangular pane (1, 2, 3, 4). - a preliminary step for the cutting and separation of the transverse portion, in which said sheet is cut from one edge to an opposite edge so as to obtain a transverse portion which is separated from the rest of the sheet, said transverse portion being constituted by a longitudinal portion of said sheet; - a first scoring step, in which multiple first mutually parallel score lines (11, 12, 13) are performed, translating the transverse portion with respect to said fixed cutting axis following each one of said first score lines (11, 12, 13), followed by - a second rotation step, in which the transverse portion is rotated through 90° with respect to said cutting axis, followed by - a third step of scoring and separation, in which multiple second score lines (21, 22, 23) are performed which are parallel to each other and perpendicular to said first score lines (11, 12, 13), translating the transverse portion with respect to said fixed cutting axis following each one of said second score lines (21, 22, 23); each one of said second score lines (21, 22, 23) intersecting at least one of said first score lines (11, 12, 13) so as to define a plurality of rectangular panes (1, 2, 3, 4); following each one of said second score lines (21, 22, 23), an outermost rectangular pane (1, 2, 3, 4) being separated from the rest of the transverse portion together with a corresponding waste (91, 92, 93) which is not separated from said rectangular pane (1, 2, 3, 4).
