TYPES OF TENSIONERS: We provide optical, graphite, Kevlar, Nextel, fiberglass, nylon and wire Fiber Tensioners and unwinders of all types for unwinding fibers, wires membranes and any other product that are on spools and need to go to or from a process.  All tensioners are bi-directional with unlimited re-wind (or take-up capabilities).  The Helman tensioner is extremely versatile.  The same tensioners that are used for optical fiber tensioning and optical fiber processing are also used for composite winding, wire tensioning and other similar winding and unwinding processes.

TENSION RANGES:  All Helman tensioners will tension from as low as 1/2 gram to 30 pounds or more.  There is no need to have different tensioners for different applications.  Full scale tension ranges start at 100 grams and can go as high as 50 to 100 pounds.  Typical metric tension ranges are 100 grams, 1000 grams, 10 Kg or 20 kg.  Typical English tension ranges are 1 pound, 5 pounds, 10 pounds, 20 pounds and 30 pounds or more.

TENSION ACCURACY:  The typical fiber tension payout accuracy is better than 0.1% of the full scale tension range which the system is currently set up on.  Usually accuracy is as high as 0.05%.  
On the 10 pound range, when care is taken while doing the set up and calibration, we have seen all fibers on the tensioner creel to be within 1/300 pound (0.03 pound). 
On a 100 gram range, we have seen tension maintained to within  + 0.05 grams (+ 50 milligrams).

PAYOUT SPEEDS: The Helman Tensioner's typical maximum payout speed is 600 feet per minute.  With the high speed option, speeds in excess of 3000 feet per minute (1000 meters per minute) can be achieved. 

TAKE UP SPEEDS: The take up (slack) rewind speed is typically around 600 feet per minute.  However, with a high speed take up option installed, take up speeds can exceed 2000 feet per minute.

We custom build tensioners for any application and for any material. 
 Our systems are so reliable that we offer a 3 year 100 % warranty.
 Maintenance free life expectancy is in excess of 21 years.
