Abstract: A machine for transforming a piece of dough of globoidal form into a substantially circular puff-pastry includes a feeding duct for receiving the pieces of dough to be worked and bringing them in a first roll train disposed below the duct for flattening the pieces of dough along a first direction and to lodge the same on an inclined plate, thus permitting the so obtained elliptical pre-manufactured doughs to slide down toward a second roll train positioned below the first roll train.Each pre-manufactured dough which is discharged from the first roll train meets a first oscillating arm which is pivoted at an end portion of a second oscillating arm which in turn is pivoted on the structure of the machine.The pre-manufactured dough pushes the first oscillating arm downward, while contemporaneously causing the second oscillating arm to be rotated until the pre-manufactured dough is completely released by the first roll train.
