Holding device for a twin pressure roller of a drafting unit

Abstract

A holding device for a twin pressure roller of a drafting unit includes a number of bottom rollers. The twin pressure roller includes a stationary axle and two rotatably supported upper rollers. The holding device includes at least one positioning element assigned to the axle of the twin pressure roller and at least one force transmission element, wherein the positioning element is arranged in the area of the center of the axle of the twin pressure roller and thus permits the twin pressure roller to move in a pendulum fashion around the center. The holding device, together with the twin pressure roller may be lifted from the bottom roller. At least one catch bearing for approximate positioning during placement on the bottom rollers is assigned to the twin pressure roller. It may further be provided that the force transmission element is arranged separately from the positioning element and that the catch bearing is integrated into the force transmission element.

1 . A holding device for a twin pressure roller of a drafting unit including a number of bottom rollers, the twin pressure roller including a stationary axle and two rotatably supported upper rollers, the holding device comprising: 
 at least one positioning element assigned to the axle of the twin pressure roller and at least one force transmission element, wherein the positioning element is arranged in a center area of the axle of the twin pressure roller and permits the twin pressure roller to move in a pendulum fashion around the center;    wherein the holding device, together with the twin pressure roller are liftable from the bottom roller; and    at least one catch bearing assigned to the twin pressure roller for approximate positioning of the twin pressure roller when placed on the bottom rollers.    
   
   
       2 . The holding device according to  claim 1 , wherein the catch bearing is assigned to the axle of the twin pressure roller.  
   
   
       3 . The holding device according to  claim 1 , wherein at least two catch bearings are arranged at a distance to one another and in close proximity to the upper rollers.  
   
   
       4 . The holding device according to  claim 2 , wherein at least two catch bearings are arranged at a distance to one another and in close proximity to the upper rollers.  
   
   
       5 . The holding device according to  claim 1 , wherein the force transmission element is arranged separately from the positioning element.  
   
   
       6 . The holding device according to  claim 2 , wherein the force transmission element is arranged separately from the positioning element.  
   
   
       7 . The holding device according to  claim 3 , wherein the force transmission element is arranged separately from the positioning element.  
   
   
       8 . The holding device according to  claim 1 , wherein the catch bearing is integrated into the force transmission element.  
   
   
       9 . The holding device according to  claim 5 , wherein the force transmission element is arranged separately from the positioning element.  
   
   
       10 . The holding device according to  claim 1 , wherein the force transmission element is integrated into the positioning element.  
   
   
       11 . The holding device according to  claim 2 , wherein the force transmission element is integrated into the positioning element.  
   
   
       12 . The holding device according to  claim 3 , wherein the force transmission element is integrated into the positioning element.
