Abstract: A dough-stretching machine, which is particularly adapted to stretch pizza dough, includes a frame associated with which are a support plane for the mass of dough to be stretched; a dough-stretching unit arranged at the top and coaxially to the support plane according to the defined vertical axis of the frame; movement apparatus for moving the support plane towards/away from the dough-stretching unit. The dough-stretching unit includes a modelling body configured to come into contact with the mass of dough; a plate in which a plurality of radial grooves are identified, each of which slidably houses a modelling element for the mass of dough; kinematic apparatus adapted to move the modelling elements along the radial grooves towards the vertical axis or away from the axis itself.
