ABSTRACT:
A pressing machine arrangement, comprising at least two dies defining a molding cavity is described.
The main feature of this machine is to comprise means for adjusting the thrust pressure exerted at least on one of the said dies (22, 255), substantially in every region of the said dies, in order to maintain substantially mating, during the stage of maximum thrust, the contours of the said dies (22, 7, 255, 332) which define the said molding cavity, by means of an analogous deformation for the said two dies. Said means comprise a cylinder (77, 213) whose head (76, 216) acting into the said dies has a relatively reduced thickness, so as to allow its deformation.
