Apparatus for guiding, conveying or treating a fiber cable

Abstract

An apparatus for guiding, conveying or treating a fiber cable 7 , comprising several driven rollers 2, 3, 4.1, 4.2 , the fiber cable being guided along the circumference of the rollers so as to partly wrap therearound. The rollers include a roller 2 for feeding the fiber cable and a roller 3 for discharging the fiber cable. The remaining rollers 4.1, 4.2, 4.3, 4.4 are disposed relative to the feeding roller and the discharging roller in such a way that the fiber cable can be guided on the rollers at a respective angle of contact of >180°. In order to involve all rollers to the same extent, the feeding roller and the inlet of the fiber cable, as well as the discharging roller and the outlet of the fiber cable, are arranged relative to each other such that the fiber cable can be guided along the circumference of the feeding roller and along the circumference of the discharging roller so as to partly wrap therearound at a respective angle of contact of >180°.

1 . An apparatus for guiding, conveying, or treating a fiber cable comprising 
 a plurality of driven rollers positioned so that a fiber cable can be guided along the circumference of each roller so as to partially wrap therearound,    said driven rollers including a feeding roller positioned adjacent an inlet for the fiber cable, a discharging roller positioned adjacent an outlet for the fiber cable, and a plurality of additional rollers arranged relative to the feeding roller and the discharging roller so that the fiber cable can be guided on the rollers at a respective angle of contact which is >180°, and    wherein the feeding roller and the inlet for the fiber cable and the discharging roller and the outlet for the fiber cable are arranged relative to each other such that the fiber cable can be guided along the circumference of the feeding roller and the circumference of the discharging roller so as to partially wrap therearound at a respective angle of contact which is >180°.    
   
   
       2 . The apparatus according to  claim 1 , wherein the fiber cable is guided on all the driven rollers so as to partly wrap therearound at a respective angle of contact of >190°.  
   
   
       3 . The apparatus according to  claim 1 , wherein the angle of contact on all the rollers are of substantially equal measure.  
   
   
       4 . The apparatus according to  claim 1 , wherein the angle of contact on the feeding roller and the discharging roller and/or the angle of contact on the additional rollers are of substantially equal measure.  
   
   
       5 . The apparatus according to  claim 1 , wherein altogether two additional rollers are provided.  
   
   
       6 . The apparatus according to  claim 5 , wherein the additional rollers are arranged between the feeding roller and the discharging roller.  
   
   
       7 . The apparatus according to  claim 5 , wherein the feeding roller and the discharging roller are arranged between the additional rollers.  
   
   
       8 . The apparatus according  claim 1 , wherein altogether three additional rollers are arranged between the feeding roller and the discharging roller.  
   
   
       9 . The apparatus according to  claim 1 , wherein altogether more than three additional rollers are arranged between the feeding roller and the discharging roller.  
   
   
       10 . The apparatus according to  claim 1 , wherein a drive motor is assigned to each of the driven rollers, and wherein the drive motors are controlled by several individual converters or by a group converter.  
   
   
       11 . The apparatus according  claim 1 , wherein the rollers are mechanically coupled by toothed wheels or chains and are driven by a drive motor using a converter.
