Roller device with adjuster device

Abstract

The invention relates to a roller device ( 1 ) comprising a stand with support posts ( 2, 12, 33 ), wherein at least one roller ( 3, 13 ) of the roller stand is arranged in the space between the support posts and at least one adjuster device ( 5, 10, 30 ) is provided for adjusting the rollers ( 3 ), wherein the at least one adjuster device ( 5, 10, 30 ) is arranged between the rollers ( 3, 13 ) and the support posts ( 2, 2 a, 2 b, 2 c, 2 d, 12, 33 ) and comprises a pressure medium adjuster body ( 14, 23, 34 ).

1 - 5 . (canceled) 
     
     
         6 . A rolling installation, comprising: a stand with housing uprights; at least one roll arranged in a space between the housing uprights; and at least one adjusting device provided for adjusting the roll, wherein the at least one adjusting device is arranged between the roll and the housing upright and includes a pressure-medium control element, wherein the pressure-medium control element comprises a hydraulic actuator with a piston/cylinder unit, and the piston/cylinder unit has a piston whose direction of motion is parallel to an axis of the roll. 
     
     
         7 . The rolling installation in accordance with  claim 6 , wherein the adjusting device has two pressure chambers for applying pressure to the piston, such that one chamber each is arranged on opposite ends of the piston. 
     
     
         8 . The rolling installation in accordance with  claim 6 , wherein a piston rod is connected with the piston and acts on the roll in a direction of adjustment by a lever arrangement, so that the piston is adjusted in a direction parallel to the roll axis, the lever being operative to bring about adjustment of the roll perpendicularly to the roll axis. 
     
     
         9 . The rolling installation in accordance with  claim 8 , and further comprising a sensor for detecting a position of the piston. 
     
     
         10 . The rolling installation in accordance with  claim 9 , wherein the sensor is integrated in a housing of the adjusting device. 
     
     
         11 . The rolling installation in accordance with  claim 9 , wherein the sensor is connected with a housing of the adjusting device.
