How can a machine extrude a round pasta shape with a hole in the middle (e.g penne), without the middle metal part blocking the hole falling away

Question

How can a round shape be made, when the middle part of the metal creating the hole needs to be attached to something, which would create a gap in the shape

Answer 1

The dough of the pasta is slightly malleable/moldable, so the central “hole” can be made by a rod held at the rear of the extruder. The dough will be pushed around the rod before being pushed outward through the extruder die; the compression around the rod will help seal the dough back up to form a continuous piece.
