Cardboard boxes are formed starting from a stamped sheet which is vertically pushed by a descending core ( 13 ) for folding the sectors ( 6 ) that are going to form the sides and those that are going to form the front ends ( 7 ), including equipment for folding of the extensions and/or flaps ( 8, 10 ) which are folded on the front ends and/or sides. The mold is intended to shape boxes having an upper horizontal bridge ( 9 ) in the sides ( 6 ), bridges presenting flaps ( 10 ) which fold over the front ends ( 7 ), being fixed to the outer face of them, with these front ends ( 7 ) in turn presenting end extensions ( 8 ) which are folded in the inner face of the sides ( 6 ). The mold includes runners ( 11 ) adjustable in height, permitting to fold the end extensions ( 8 ) of the front ends ( 7 ), also having wedges in ramp ( 14 ) and presses ( 15 ) with an inclined plane ( 16 ), for folding the flaps ( 10 ) of the upper bridges ( 9 ) of the sides ( 6 ), these flaps ( 10 ) being folded on the front ends ( 7 ).
