 | Description |    |  
 VacuTens is the key component for gently feeding tension-sensible coilable materials. Fine and ultra-fine wires, capillary membrane fibres, filaments, optical fibers, etc.  VacuTens operates tension-controlled, adjustable in a range of 5 to 100cN. With version SLT (Super Low Tension) even beginning at 2cN.  The material is unwound tangentially (torsion-free).  The usage is stand-alone, that means without an electrical link-up to the production line. Thereby VacuTens absolutely ensures reliable processing and stability.
  Function VacuTens is based on a highly dynamic, extra low-mass material accumulator.
   The accumulator position is detected electronically, used to control the electromotively driven unwinding spindle.
   A high resolution tension sensor with superb long-term stability measures the tension in the line.
   The package support is done comfortably by means of a chuck with quick-mount function.
  Design variants The described design is only examplary.  VacuTens kann be customized regarding •  tension range •  accumulator volume •  dynamics •  bending radius |  
   |    |  
 
 | Special features |    |  
 •  similarly suitable for gentle feeding     - into quasi-static, slow-going processes as well as      - on high-dynamic and fast applications or     - on discontinuous material take-off  •  tangential, torsion-free unwinding •  offers high accumulator capacity •  very low masses moving •  accumulator pulley with air suspension guarantees minimal friction moments and     enables an extra low tension niveau •  low vacuum consumption (3 to 10 l/min) •  compact design, small size ration •  gentle to the material by avoiding tension peaks •  large bending radius for the material •  stepless adjustment of line tension •  spool spanning with quick-mounting function •  suitable for cleanroom applications •  longlife, nonwearing and maintenance-free •  modular concept - for fixed installation or with mobile support frame
