Production of flat conductor cables

Abstract

The invention pertains to a method of transporting a flat conductor cable ( 1 ) to, between and from processing stations ( 2, 3 ) by means of drive rolls ( 4′, 4″; 5′, 5″; 6′, 6″ ). The invention is characterized in that drive rolls ( 4′, 4″; 5′, 5″; 6′, 6″ ) are driven at differing tangential surface velocities. The invention also pertains to a device for carrying out such a method.

1 . Method of transporting a flat conductor cable to, between and from processing stations by means of drive rolls, characterized in that the drive rolls are driven at differing tangential surface velocities.  
     
     
         2 . Method according to  claim 1 , characterized in that the flat conductor cable moves from drive rolls with lesser tangential surface velocity to drive rolls with greater tangential surface velocity.  
     
     
         3 . Method according to  claim 1  or  2 , characterized in that the drive torque of at least one drive roll is less than the frictional force between the surface of the drive roll and the flat conductor cable, multiplied by the radius of the drive roll.  
     
     
         4 . Device for carrying out the method according to one of the preceding claims, with drive rolls that set a flat conductor cable into motion, characterized in that the drive rolls are driven at differing tangential surface velocities.  
     
     
         5 . Device according to  claim 4 , characterized in that a slip clutch is provided between the surface and the drive system for at least one drive roll.  
     
     
         6 . Device according to  claim 5 , characterized in that the slip clutch is constructed mechanically, pneumatically or electrically.  
     
     
         7 . Device according to one of claims  4 - 6 , characterized in that at least two drive rolls are driven with different torques.  
     
     
         8 . Device according to claims  7  and  5 , characterized in that the differing torques are secured by differently constructed or calibrated slip clutches.
