Roll system, particularly a contact roll system of a winding machine

Abstract

In winding machines, known roll systems are used that contain a number of freely rotatable roll segments ( 3 ), which are situated next to one another face to face and mounted in a manner that enables them to move perpendicular to their rotation axis ( 4 ). According to the invention, the roll segments ( 3 ) are mounted so that only one respective face is mounted on a bearing journal ( 5 ), which is fastened in an interspaced manner to a bearing plate ( 6 ) that can move perpendicular to the rotation axis ( 4 ). An annular slot ( 15 ) is fashioned in at least one inner side of each bearing plate ( 6 ), and the end of a roll segment ( 3 ) can rotate without touching inside this annular slot.

1 . A roll system, especially a contact roll system of a winding machine having a plurality of roll segments ( 3 ) freely rotatable adjacent one another, end face to end face and mounted so as to be movable perpendicular, to their rotation axes ( 4 ), characterized in that the roll segments ( 3 ) are each journaled at one end face on a respective bearing pin ( 5 ) which projects from a bearing plate ( 6 ) on which it is fastened and which is movable perpendicularly to the rotation axis ( 4 ) whereby in at least one inner side of each bearing plate ( 6 ) an annular groove ( 15 ) is machined in which he end of a roll segment ( 3 ) can rotate contactlessly.  
   
   
       2 . The roll system according to  claim 1  characterized in that each two roll segments ( 3 . 1 ,  3 . 2 ) is held on a common bearing plate ( 6 ) with bearing pins ( 5 . 1 ,  5 . 2 ) projecting from opposite sides.  
   
   
       3 . The roll system according to  claim 1  characterized in that the roll segments are mounted so as to be linearly shiftable perpendicular to their rotation axes ( 4 ).  
   
   
       4 . The roll system according to  claim 1  characterized in that the bearing plates ( 6 ) are mounted so as to be swingable perpendicular to the rotation axis ( 4 ).  
   
   
       5 . The roll system according to  claim 1  characterized in that the bearing plates ( 6 ) are mounted on a common traverse ( 9 ) which extends transversely and are each movable by a respective drive ( 10 ) perpendicular to the rotation axis.  
   
   
       6 . A winding machine for winding up a continuous traveling web ( 1 ) of material, especially a paper web or a plastic foil or film, characterized in that it contains a roll system according to  claim 1  as a contact roll system.
