  • Patent number: 7063010
    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.
    Type: Grant

  • Patent number: 6938450
    Abstract: The tensioner assembly is provided for clamping at least two objects and comprises a tie rod member, a thrust ring positioned on the tie rod member against one of the objects, a first retaining member for removably engaging a distal end of the tie rod member, and a second retaining member for removably engaging the distal end of the tie rod member between the thrust ring and said first nut member and spaced apart therefrom. Each of the first and second retaining members is provided with a set of jackbolts adapted to engage complementary holes therein and to extend from the holes to compressively bias the thrust ring. The total load experienced by the tensioner assembly is shared by two retaining members so that load carried by the first retaining member remains substantially constant during operation, while the second retaining member is subject to stress variation.
