    • The invention relates to a structure for presses, a resistant structure of which comprises at least a resistant element (1) which, in turn, comprises an annular element or arch (2), internally of which are predisposed two facing surfaces (20), diametrically opposite one another, between which at least a power organ (5) is insertable, which power organ (5) is suitable for compressing an object or material to be pressed between two bodies, such as to unload, on the facing surfaces (20), equal and opposite reactions of the pressing action. Full-thickness cuts (3) are symmetrically arranged at ends of the facing surfaces (20), the cuts (3) having a predetermined width, each of which, starting from the end of the relative facing surface (20), develops over an arc of a polycentric curve which exhibits at least a first tract (22) the most external surface of which connects with the lateral surface (24) of the vertical portion of the annular element or arch (2), and at least a second tract (23) which is connected to the first tract (22), is shaped as an arc of a circle and extends over a portion of not less than a quarter of an arc of circumference. At least a plate (4) is housed in each full-thickness cut (3) which plate (4) is provided with opposite surfaces that are destined to come into contact with the reciprocally-facing surfaces delimiting each full-thickness cut (3).
