| 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
