Tensioners


 

 
Compensator

 

A compensator is used when the yarn needs to be stretched before weft-insertion. A compensator can be used for most yarns, but is mainly used for twist yarns. There are versions for mounting on both the input and output sides of a weft-feeder. Combinations of leaf brake assemblies fitted with compensators are available.


 
Rotating disc tensioner

 

Exists in two versions, where the metal disc execution is suitable for spun yarns, and the ceramic disc execution is recommended for filament yarns. This brake type has one major advantage, it is self-cleaning. Main use is at the inlet side of a weft feeder.

 


 
Twine-Around brake

 

The Twine-Around Brake is used for yarns which have a twist greater than 2000 turns/meter (crepe, silk, viscose, etc.), and where snarls may form during yarn movement.

 


 
Leaf tensioner

 

The traditional Leaf brake system is very versatile for applying tension on to a yarn, and covers most yarns today used. Our specific recommendation is for high twist yarns, stiff yarns and heavy yarns.

The Leaf Tensioner consists of minimum two leaves.
The leaf itself varies in thickness depending on tension required. Typical thickness varies from 0.08mm to 0.20mm depending on tension required. Most of the types available have a surface treatment of Hard chrome min 5 um up to 12um, this to extend the lifetime of the leaf.

For special applications, such as thin yarn sizes (high yarn count) and low tension is required, a special treatment named DLC has been proven to give excellent results under certain conditions.
