A cutting method for cutting a laminated glass sheet manually comprising two side glass sheets and one intermediate layer of thermoplastic material; the sheet is cut along at least a first diagonal cutting line forming an angle other than zero and other than 90° with a peripheral side of the sheet for forming at least two lengths of sheet, the method comprising the steps of: - using a cutting table comprising a sheet supporting plane, a first cutting assembly for the side glass sheets having incision tools which are movable along a first advancement direction, a second cutting assembly for the intermediate layer of thermoplastic material, a row of fixed reference pegs, a row of reference pegs adjustable in position along said sheet supporting plane in a positioning direction perpendicular to said advancement direction, and a hinging head for said laminated sheet rotates idly around its own axis perpendicular to the supporting plane and intersecting said advancement direction and motorized to translate parallel with the advancement direction, and an electronic control unit of the cutting assembly, the adjustable reference pegs and of said hinging head, - positioning the laminated glass sheet on said support plane, bringing the cutting line towards said advancement direction, - truncating said side glass sheets and cutting said intermediate layer along said cutting lines creating the two lengths of the glass sheet; characterised in that cutting along said first diagonal cutting line comprises the steps of: - taking said first cutting line so that it intersects said advancement direction at an intersection point, bringing a peripheral edge of said laminated sheet into abutment against at least said adjustable reference pins previously positioned by said electronic command and control unit, according to the position of said first cutting line, - hinging said laminated sheet in said intersection point by means of said hinging head, - repositioning said adjustable reference pins along said positioning direction or said hinging head along the advancement direction by means of said command and control unit, according to the angle formed by said first line with said peripheral edge, - arranging a free reference bar abutting against said supporting plane and against the adjustable reference pins or against the fixed reference pins, - rotating manually the laminated sheet around an axis passing by said intersection point until bringing an external peripheral point of the laminated sheet into abutment against said free reference bar, - truncating said side glass sheets and cutting the intermediate layer along said first cutting line, and distancing said reference bar from said reference pins. - using a cutting table comprising a sheet supporting plane, a first cutting assembly for the side glass sheets having incision tools which are movable along a first advancement direction, a second cutting assembly for the intermediate layer of thermoplastic material, a row of fixed reference pegs, a row of reference pegs adjustable in position along said sheet supporting plane in a positioning direction perpendicular to said advancement direction, and a hinging head for said laminated sheet rotates idly around its own axis perpendicular to the supporting plane and intersecting said advancement direction and motorized to translate parallel with the advancement direction, and an electronic control unit of the cutting assembly, the adjustable reference pegs and of said hinging head, - positioning the laminated glass sheet on said support plane, bringing the cutting line towards said advancement direction, - truncating said side glass sheets and cutting said intermediate layer along said cutting lines creating the two lengths of the glass sheet; - taking said first cutting line so that it intersects said advancement direction at an intersection point, bringing a peripheral edge of said laminated sheet into abutment against at least said adjustable reference pins previously positioned by said electronic command and control unit, according to the position of said first cutting line, - hinging said laminated sheet in said intersection point by means of said hinging head, - repositioning said adjustable reference pins along said positioning direction or said hinging head along the advancement direction by means of said command and control unit, according to the angle formed by said first line with said peripheral edge, - arranging a free reference bar abutting against said supporting plane and against the adjustable reference pins or against the fixed reference pins, - rotating manually the laminated sheet around an axis passing by said intersection point until bringing an external peripheral point of the laminated sheet into abutment against said free reference bar, - truncating said side glass sheets and cutting the intermediate layer along said first cutting line, and distancing said reference bar from said reference pins.
