A first and second bottom die are fastened to a body at a lateral distance from one another. An upper die support (25) is pivotably accommodated on the front end of a press carriage (15) which can reciprocate on the two bottom dies (12), (14) and the upper die support (25) supports in its turn first, second and third upper moulding dies (33), (36), (43) which are arranged at equal intervals on an arc of a circle. The upper die support (25) is alternately pivoted between a first position, in which the first and second upper dies are aligned with the first and second bottom dies, and a second position in which the second and third upper dies are aligned with the first and second bottom dies. In the first position, the first upper moulding die (33) imparts a first shape to a workpiece (b), by means of compression of the workpiece between the first upper die and the first bottom die. In the second position, the second upper die accommodates the workpiece to which the first shape has been imparted and then, in the second position too, a second shape is imparted to the workpiece by means of compression of the workpiece between the second upper moulding die (36) and the second bottom die (14). In addition, in the second position, the workpiece, to which the second shape has already been imparted, has a third shape imparted to it by the third upper moulding die (43) by means of compression between the third upper die and the second bottom die.
