Definitions

  • a press comprising a press axis; a cylinder crossmember; press ram means; cylinder means mounted by said cylinder cross-member for moving said press ram means along the press axis; a counter cross-member; at least two tie members in tension interconnecting said cylinder cross-member and said counter cross-member, each said tie member comprising a stack of separate and unbonded sheet metal laminations each said lamination being of generally rectangular cross-section and having two parallel broad sides and two narrow sides, the perpendicular to the center of each said broad side intersecting said press axis so that the laminations closest to the press axis absorb a higher tensile stress than the laminations which are further from the press axis; hollow rectangular support members in compression between said cross-members and surrounding said stacks of sheet metal laminations, said support members comprising four walls, two of which walls are parallel to said broad sides of said laminations, the perpendicular to the center of each of said two walls intersecting said press axis; and spacer members between at least one
