Abstract: An apparatus comprises a mould part having a forming chamber and a filling device for filling the forming chamber with a mouldable material. The filling device comprises an entry duct for a flow of mouldable material and air and a preliminary chamber communicating with the forming chamber. The entry duct opens into the preliminary chamber in a position such as to send the flow of mouldable material and air towards the forming chamber with a helicoidal movement, so as to separate the mouldable material from the air.

Abstract: A moulding apparatus for forming an object with a mouldable material, the moulding apparatus having a forming region delimited by a lateral surface extending around a central zone. The moulding apparatus includes a plurality of sectors defining the lateral surface, each sector having a body delimited by a forming surface, at least a first pushing device for applying, on a first sector of said plurality, a first force directed towards the central zone in a first direction, at least a second pushing device for applying, on a second sector of said plurality, a second force directed towards the central zone in a second direction, and the second direction being arranged transversely to the first direction.
