Roll stand for absorbing rolling forces

Abstract

In order to simplify roll adjustment in a roll stand when changing the rolls, a roll stand absorbs rolling forces of at least three rolls mounted on both sides in bearing seats of the roll stand that absorb rolling forces, in each instance. At least the bearing seats of one roll are disposed in a stand body jointly with a bearing seat of another roll, in each instance. One of the stand bodies has fixed bearings of the two related rolls, in each instance, and/or one of the stand bodies has floating bearings of the two related rolls, in each instance.

         5 . The roll stand according to  claim 3 , wherein the force element is a screw or a tie rod. 
     
     
         6 . The roll stand according to  claim 3 , wherein the force element is disposed axially in a region of a roll pass bottom of the rolls. 
     
     
         7 . The roll stand according to  claim 3 , wherein the force element is disposed axially in a region of a roll recess of the first roll stand for a roll drive journal of the rolls. 
     
     
         8 . A roll stand for absorbing rolling forces comprising:
 (a) a first roll mounted in first and second bearing seats;   (b) a second roll mounted in third and fourth bearing seats;   (c) a third roll mounted in fifth and sixth bearing seats;   (d) a first stand body;   (e) a second stand body; and   (f) a third stand body;   wherein each bearing seat absorbs rolling forces and at least the bearing seats of the first roll are disposed in the first stand body jointly with a bearing seat of the second roll; and   wherein the first and second stand bodies stand in contact with one another by way of a contact surface.   
     
     
         9 . A roll stand for absorbing rolling forces comprising:
 (a) a first roll mounted in first and second bearing seats;   (b) a second roll mounted in third and fourth bearing seats;   (c) a third roll mounted in fifth and sixth bearing seats;   (d) a first stand body;   (e) a second stand body; and   (f) a third stand body;   wherein each bearing seat absorbs rolling forces and at least the bearing seats of the first roll are disposed in the first stand body jointly with a bearing seat of the second roll; and   wherein the first and second stand bodies are directly connected with one another by way of a contact surface.   
     
     
         10 . The roll stand according to  claim 9 , wherein the first and second stand bodies are directly connected with one another by way of an articulation or by way of a releasable connection. 
     
     
         11 . The roll stand according to  claim 10 , wherein the first and second stand bodies are directly connected with one another by way of a screw connection. 
     
     
         12 . The roll stand according to  claim 8 , wherein the contact surface is disposed in a low-force region. 
     
     
         13 . A roll stand for absorbing rolling forces comprising:
 (a) a first roll mounted in first and second bearing seats;   (b) a second roll mounted in third and fourth bearing seats;   (c) a third roll mounted in fifth and sixth bearing seats;   (d) a first stand body;   (e) a second stand body; and   (f) a third stand body;   wherein each bearing seat absorbs rolling forces and at least the bearing seats of the first roll are disposed in the first stand body jointly with a bearing seat of the second roll; and   wherein the first and second stand bodies are connected with one another in a low-force region of the roll stand.
