1. A dough-stretching machine for stretching a mass of dough, comprising:
a frame having a vertical axis extending therethrough;
a support plane for the mass of dough to be stretched upon during operation, said support plane being disposed within said frame and having said vertical axis pass therethrough;
a dough-stretching unit disposed above said support plane along said vertical axis of said frame;
movement means for moving said support plane towards or away from said dough-stretching unit;
said dough-stretching unit comprising:
a modelling body configured to come into contact with said mass of dough during operation;
a plate having a plurality of radial grooves, each of said plurality of radial grooves slidably housing a modelling element;
kinematic means adapted to move said modelling elements along said radial grooves towards or away from said vertical axis;
said kinematic means comprising:
a threaded shaft having one end operatively connected to a motor and an opposite end rotatably associated with said plate, said motor being configured to rotate said threaded shaft;
a central core provided with a nut fixed on said threaded shaft;
a plurality of rods each having one end hinged to one of said modelling elements and an opposite end hinged to said central core;
wherein said modelling elements are displaced towards or away from said vertical axis when said threaded shaft is rotated by said motor, said threaded shaft causing a downward or upward displacement of said central core depending on a direction of rotation of said threaded shaft.
