ABSTRACT:
A mould holding cross member (9) according to the invention comprises a support base (91) a suitable to compress the mould (S) and more projecting, in the mould closing direction, than the ends (90) with which the cross member is connected to the moving columns (6) of the press on which it is fitted. The base (91) is connected to the rest of the cross member by a narrow portion (99) which extends in the central area of the base and between the projections of the hinging areas (7, 8) of the double toggle of the press on the press bed (2), and substantially not outside those projections. In this way the pressures are more uniformly distributed on the mould (S). The present invention also concerns a press fitted with a cross member (9) as defined above.
