Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
71 words
A press comprising a press frame formed of a lower yoke and an upper yoke and intermediate members for interconnecting said lower yoke with said upper yoke, each intermediate member being defined by a hollow column member having an internal compartment, and a plurality of preloaded tensioning cables arranged in said internal compartments of said hollow column members and which, apart from said intermediate members, hold together both of said yokes.
Claim 2
Dependent Claim
71 words
A press comprising a press frame formed of a lower yoke and an upper yoke and intermediate members for interconnecting said lower yoke with said upper yoke, each intermediate member being defined by a hollow column member having an internal compartment, and a plurality of preloaded tensioning cables arranged in said internal compartments of said hollow column members and which, apart from said intermediate members, hold together both of said yokes.
Claim 3
Dependent Claim
57 words
A press as defined in claim 1, wherein each yoke member is equipped with a throughpassage opening which substantially corresponds in diameter to that of said internal compartment of said hollow column members and through which the tensioning cables are passed, and tensioning plate members arranged at the outside of said yokes for retaining said tensioning cables.
Claim 4
Dependent Claim
37 words
A press as defined in claim 1, further including a movable press punch mounted at said press frame, guide means arranged at said hollow column members and serving to guide said movable press punch of the press.
Claim 5
Dependent Claim
27 words
A press as defined in claim 1, wherein each of said plurality of preloaded tensioning cables can be separately preloaded and independently of the other tensioning cables.
Claim 6
Dependent Claim
116 words
A press comprising a press frame formed of a lower yoke and an upper yoke, intermediate members for interconnecting said lower yoke and said upper yoke, each intermediate member comprising a hollow column member having an internal compartment extending between opposed ends of each associated hollow column member, and a plurality of preloaded tensioning cables arranged in the internal compartment of at least one of said hollow column members, said preloaded tensioning cables being in a form of separate cable members of finite length which extend in spaced relationship from one another between said opposed ends of said at least one hollow column member, said preloaded tensioning cables serving to hold together both of said yokes.
Claim 7
Dependent Claim
116 words
A press comprising a press frame formed of a lower yoke and an upper yoke, intermediate members for interconnecting said lower yoke and said upper yoke, each intermediate member comprising a hollow column member having an internal compartment extending between opposed ends of each associated hollow column member, and a plurality of preloaded tensioning cables arranged in the internal compartment of at least one of said hollow column members, said preloaded tensioning cables being in a form of separate cable members of finite length which extend in spaced relationship from one another between said opposed ends of said at least one hollow column member, said preloaded tensioning cables serving to hold together both of said yokes.
