A machine for moulding dough for oven-baked products, of the type comprising: - a hopper open underneath designed to contain the dough to be moulded; - a rotary moulding roll, having on its outer lateral surface a plurality of forming moulds; - first an second feed rolls (4A, 4B), configured for pushing the dough coming from said hopper into said moulds of said moulding roll to form semi-finished products, each in a respective mould; and - a conveyor belt for feeding said semi-finished products to subsequent processing stations, wherein said belt runs over said moulding roll for a stretch, coming into contact with said lateral surface of said moulding roll in a first angular position (θ1) around said moulding roll, and detaching from said lateral surface in a second angular position (θ2) downstream of said first angular position (θ1), with reference to the direction of rotation of said roll, so as to remove said semi-finished products from said forming moulds, wherein said first angular position (θ1) is located before the position of 270°, in the case of rotation in a counterclockwise direction by said moulding roll, and beyond the position of 270°, in the case of rotation in a clockwise direction, in such a way that said belt run over said moulding roll between said first and second angular positions, will keep said semi-finished products in position, within said moulds, against the action of the force of gravity, said angular positions referring to the goniometric circumference in a cartesian plane set orthogonal to the axis of rotation of said moulding roll and with the origin of the axes of the co-ordinates positioned on said axis of rotation, where the angles are measured in a counterclockwise direction starting from the point of intersection between the circumference and the positive semi-axis of abscissae, wherein said first feed roll and said second feed roll are opposed to each other and are positioned underneath said hopper so as to receive in the space comprised between them the dough that is delivered through the bottom of said hopper, and wherein said first and second feed rolls (4A, 4B) are positioned above said moulding roll, wherein said first and second rolls (4A, 4B) are prearranged for turning in opposite directions so as to determine a flow of dough directed against said moulding roll. - a hopper open underneath designed to contain the dough to be moulded; - a rotary moulding roll, having on its outer lateral surface a plurality of forming moulds; - first an second feed rolls (4A, 4B), configured for pushing the dough coming from said hopper into said moulds of said moulding roll to form semi-finished products, each in a respective mould; and - a conveyor belt for feeding said semi-finished products to subsequent processing stations, wherein said belt runs over said moulding roll for a stretch, coming into contact with said lateral surface of said moulding roll in a first angular position (θ1) around said moulding roll, and detaching from said lateral surface in a second angular position (θ2) downstream of said first angular position (θ1), with reference to the direction of rotation of said roll, so as to remove said semi-finished products from said forming moulds,
