Abstract
A platen design is provided for a C-frame press whereby an un-stiffened platen column connected in series to the tie rod; therefore, the stiffness of the tie rod is reduced. The unique design improves the fatigue strength of the tie rod by moving the reinforcing webs away from the column and directly onto the platen main body portion.
