ABSTRACT:
A structure for presses includes: a resistant structure having at least one resistance element having a flat annular element internally of which and in diametrically opposite positions two facing surfaces are arranged, between which facing surfaces at least one tool can be inserted, for exerting a pressing action and compressing between two bodies, the two facing surfaces receiving equal and opposite reactions to the pressing action. Cuts at ends of the facing surfaces involve a total thickness of the facing surface. Each cut includes a first tract parallel to a pressing direction and a second circular part; the circular second part constituting a snug seating for discs. Interpositioning elements are provided for being interpositioned between ends of the facing surfaces so that two resultants, parallel to the pressing direction, of action exerted on each facing surface are located externally to centers of corresponding circular second parts.
