Abstract
Abstract A rolling mill is disclosed containing a roll stand equipped with two work rolls which are braced at back-up or support rolls which can be constructed as controlled deflection rolls. The work rolls are equipped at their opposed ends with bending devices for applying a bending moment. Simplified designs of the rolling mill contemplate constructing one of the back-up or support rolls as a solid roll. Furthermore, one of the work rolls can be omitted.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
A rolling mill for rolling substantially web-like materials, comprising; at least one work roll; a counter roll with which cooperates said at least one work roll; said work roll and said counter roll defining a press nip for the material to be rolled; a support roll in engagement with said work roll; said support roll comprising a controlled deflection roll; said controlled deflection roll having a length of extent and comprising: a stationary roll support; a roll shell rotatable about said stationary roll support; and support elements supporting said rotatable roll shell at said stationary roll support by exerting supporting forces therebetween; bending devices coacting with said work roll at opposite ends thereof for applying a bending moment thereto; and means connected to said bending devices for actuation thereof.
Claim 2
Dependent Claim
129 words
A rolling mill for rolling substantially web-like materials, comprising; at least one work roll; a counter roll with which cooperates said at least one work roll; said work roll and said counter roll defining a press nip for the material to be rolled; a support roll in engagement with said work roll; said support roll comprising a controlled deflection roll; said controlled deflection roll having a length of extent and comprising: a stationary roll support; a roll shell rotatable about said stationary roll support; and support elements supporting said rotatable roll shell at said stationary roll support by exerting supporting forces therebetween; bending devices coacting with said work roll at opposite ends thereof for applying a bending moment thereto; and means connected to said bending devices for actuation thereof.
Claim 3
Dependent Claim
53 words
The rolling mill as defined in claim 1, wherein: said counter roll comprises a further work roll; bending devices provided at the opposite ends of said counter roll constituting a further work roll in order to apply bending moments thereto; and a support roll at which there is supported said further work roll.
Claim 4
Dependent Claim
64 words
The rolling mill as defined in claim 2, wherein: said support roll of said further work roll comprises a controlled deflection roll; said controlled deflection roll of said support roll or said further work roll comprising: a stationary roll support; a rotatable roll shell rotatable about said stationary roll support; and support elements for supporting said rotatable roll shell at said stationary roll support.
Claim 5
Dependent Claim
19 words
The rolling mill as defined in claim 1, wherein: at least said work roll has a substantially cylindrical configuration.
Claim 6
Dependent Claim
19 words
The rolling mill as defined in claim 1, wherein: at least said support roll has a substantially cylindrical configuration.
Claim 7
Dependent Claim
22 words
The rolling mill as defined in claim 1, wherein: both said work roll and said support roll possess a substantially cylindrical configuration.
