Abstract
Abstract A beam provides a support for a series of rolls journaled side by side between bearing brackets. The bearing brackets are forked and movable vertically in relation to the beam. The relative movement of the brackets is controlled by, e.g., pressure bellows, diaphragm cylinders, pneumatic or hydraulic cylinders and the like. The rolls are journaled between the bearing brackets in pivot bearings mounted in the furcations of the bearings. Between these furcations there has been journaled a smaller diameter intermediate roll to establish a substantially continuous line of contact together with the rolls. By the aid of the control elements disposed between the beam and the brackets the shape of the contact line is changed as desired. The combination of rolls may be used as a loading roll for a roll of a material web which is to be wound up, for the purpose of achieving uniform lineal pressure over the entire width of the roll. The combination may also be utilized as a support roll for a moving web, wire or felt to equalize differences in tension occuring in the direction across the wire, felt or material web.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
140 words
A roll assembly providing a substantially uninterrupted line of work contact comprising a transverse beam, a plurality of bearing units mounted on the beam, a pressure control member mounted upon each of said bearing units, means for connecting said pressure control members to the bearing units, a plurality of first rolls pivotally mounted between the bearing units, journalled at a predetermined distance one from the other to the bearing units, said rolls being vertically displaceable in relation to the beam, a plurality of second intermediate rolls of smaller diameter pivotally mounted on said bearing units between adjacent pairs of said first rolls, the axis of said second rolls being offset from the axis of said first rolls whereby a single substantially continuous line of contact with a workpiece is established across the faces of said first and said second rolls.
Claim 2
Dependent Claim

A roll assembly providing a substantially uninterrupted line of work contact comprising a transverse beam, a plurality of bearing units mounted on the beam, a pressure control member mounted upon each of said bearing units, means for connecting said pressure control members to the bearing units, a plurality of first rolls pivotally mounted between the bearing units, journalled at a predetermined distance one from the other to the bearing units, said rolls being vertically displaceable in relation to the beam, a plurality of second intermediate rolls of smaller diameter pivotally mounted on said bearing units between adjacent pairs of said first rolls, the axis of said second rolls being offset from the axis of said first rolls whereby a single substantially continuous line of contact with a workpiece is established across the faces of said first and said second rolls.
Claim 3
Dependent Claim
28 words
The roll assembly according to claim 1 wherein the pressure control members are bellows and the means for connecting the bellows are pipes filled with a hydraulic fluid.
Claim 4
Dependent Claim
23 words
The roll assembly according to claim 2 wherein the bearing units are cup shaped and form sockets to which are mounted said bellows.
Claim 5
Dependent Claim
23 words

Claim 6
Dependent Claim
36 words
The assembly according to claim 1, wherein the said first rolls have shafts and the shaft of adjacent rolls are mutually connected with a universal joint in order to rotate the rolls at the same speed.
Claim 7
Dependent Claim
46 words
