 at least one web guiding wall fixed to the ceiling adjacent to the paper shaft;    a frame;    at least one guide roll mounted in the frame; and    at least two holding apparatuses for fastening the web guiding element to the at least one web guiding wall;    wherein the frame and the guide rolls form a pre-assembled unit which can be received in the paper shaft and fixed to said at least one web guiding wall by the holding apparatuses.    
     
     
         2 . The web guiding element of  claim 1  wherein the pre-assembled unit has a length dimension and a width dimension which are less than the length dimension and the width dimension of the paper shaft.  
     
     
         3 . The web guiding element of  claim 1  wherein the pre-assembled unit has a height which is greater than the height of the paper shaft.  
     
     
         5 . The web guiding element of  claim 1  wherein the frame comprises at least one wall formed by a sound insulation element.  
     
     
         6 . The web guiding element of  claim 1  further comprising at least one sound insulation element configured as a holding element of the at least one guide roll.  
     
     
         7 . The web guiding element of  claim 1  wherein each said holding apparatus comprises a locating pin received in a hole in the web guiding wall, and a pin element received in the locating pin.  
     
     
         8 . The web guiding element of  claim 1  further comprising a holding apparatus arranged on the frame for fastening the preassembled unit to the ceiling in the reel changer region.  
     
     
         9 . The web guiding element of  claim 8  wherein the further holding apparatus is configured as one of an angular element and a U-shaped rail.  
     
     
         10 . The web guiding element of  claim 1  further comprising adjusting elements arranged on the frame, said adjusting elements being useful for changing the alignment of the guide rolls.  
     
     
         11 . The web guiding element  1  wherein the guide rolls have axes which are offset with respect to one another or in a line.
