Реферат: A moulding apparatus for forming an object (20) with a mouldable material, the moulding apparatus having a forming region (4) delimited by a lateral surface (5) extending around a central zone (6). The moulding apparatus comprises: a plurality of sectors (8; 80; 108; 208) defining the lateral surface (5), each sector (8; 80; 108; 208) having a body (9) delimited by a forming surface (11; 311), at least a first pushing device for applying, on a first sector (8a) of said plurality, a first force (F1) directed towards the central zone (6) in a first direction (D1), at least a second pushing device for applying, on a second sector (8b) of said plurality, a second force (F2) directed towards the central zone (6) in a second direction (D2), the second direction being arranged transversely to the first direction (D1). The second sector (8b) is in contact with the first sector (8a) for transmitting the second force (F2) to the first sector (8a), so that the forming surface (11 ) of the first sector (8a) is moved towards the central zone (6) under the combined action of the first force (F1 ) and the second force (F2), in order to reduce the volume of the forming region (4).
