Machine for moulding dough for oven-baked products

A machine for moulding dough for oven-baked products, of the type comprising:

• a hopper (6) open underneath designed to contain the dough to be moulded;
• a rotary moulding roll (2), having on its outer lateral surface a plurality of forming moulds (2′);
• at least one rotary feed roll (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 (8) for feeding said semi-finished products to subsequent processing stations, wherein said belt runs over said moulding roll for a stretch (2), coming into contact with said lateral surface of said feed roll in a first angular position (θ1) around said feed 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 (2′),
• said machine being characterized in that 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 (2), and beyond the position of 270°, in the case of rotation in a clockwise direction, in such a way that said belt (8) run over said moulding roll (2) 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 (2) 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.
