A compression moulding machine comprises: an extrusion unit configured to extrude a rod of pasty polymeric material; a cutting element, configured to portion the rod into individual charges; a rotary carousel, including a plurality of moulds, each mould being configured to receive a respective charge and to form a corresponding object from the charge; a feeder, configured to convey each charge to a respective mould at a feed position; an inspecting device, configured to capture inspection data, representing a composition of the rod or of the charges.

In an embodiment, an electrospinning apparatus includes a transfer unit, a spinning head and an air ejection unit. In the transfer unit, a transfer target is transferred along a transfer direction, and a spinning head is capable of ejecting a material liquid toward the transfer unit from a first direction, which intersects the transfer direction. The air ejection unit forms an air flow that flows across the transfer unit toward an area located on an opposite side across the transfer unit in a second direction, which intersects both the transfer direction and the first direction, by ejecting air against the transfer unit from one side of the second direction.
