A press station for a forming machine for forming articles from paper has a chamber consisting of halves (50, 52). The two halves of the chamber are able to be closed together and the chamber can be evacuated through a main vacuum manifold (68) in order to bring the upper die (36) mounted on platen (38) into pressing contact with a fragile moulding positioned on lower die (32) mounted on platen (36), in order to form the required article.
