Abstract
Abstract A controlled deflection roll contains a stationary roll support or beam and a roll shell or jacket rotatable about the stationary roll support. The rotatable roll shell is supported upon the stationary roll support by means of hydrostatic support or pressure elements. The roll shell is displaceably guided in guides in relation to the stationary roll support for movement in a press or pressure plane. Between the rotatable roll shell and the stationary roll support there are arranged supporting or carrier members which are suitable for taking-up the inherent weight of the rotatable roll shell within the range of mobility of the rotatable roll shell in relation to the stationary roll support or beam.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
127 words
A controlled deflection roll comprising: a stationary roll support; a rotatable roll shell mounted to be rotatable about said stationary roll support; support elements for supporting said rotatable roll shell upon said stationary roll support; means for enabling displacement of the rotatable roll shell in relation to the stationary roll support in a press plane within a predetermined mobility range; supporting members interposed between the stationary roll support and the rotatable roll shell; and said supporting members serving for continuously taking-up the inherent weight of the rotatable roll shell and parts of the roll movable in conjunction with the rotatable roll shell within the mobility range of the rotatable roll shell in relation to the stationary roll support at least during operation of the controlled deflection roll.
Claim 2
Dependent Claim
127 words
A controlled deflection roll comprising: a stationary roll support; a rotatable roll shell mounted to be rotatable about said stationary roll support; support elements for supporting said rotatable roll shell upon said stationary roll support; means for enabling displacement of the rotatable roll shell in relation to the stationary roll support in a press plane within a predetermined mobility range; supporting members interposed between the stationary roll support and the rotatable roll shell; and said supporting members serving for continuously taking-up the inherent weight of the rotatable roll shell and parts of the roll movable in conjunction with the rotatable roll shell within the mobility range of the rotatable roll shell in relation to the stationary roll support at least during operation of the controlled deflection roll.

Dependent Claim
16 words
The controlled deflection roll as defined in claim 2, wherein: said supporting members comprise fluid springs.
Claim 8
Dependent Claim
37 words
The controlled deflection roll as defined in claim 6, further including: positioning feelers provided for said supporting members; and regulator means actuatable by said positioning feelers for regulating a continuous supporting force exerted by said supporting members.
