ABSTRACT:
Two mould portion carriers (14,16) are supported for pivoting movement about a column (12). Two cooling passages (44,48) pass through the column and each is connected to a passage (56,96) in one of the carriers. Each passage (56,96) in a carrier is connected to passages (82,84,86,88) in a mould portion (18) supported by the carrier (14,16) so that air under pressure supplied to the passages (44,48) in the column (12) is supplied to the passages in the mould portion to cool the mould portion. The air supply to each of the passages in the column is controllable independently so that the air supply to each mould portion is independent.
