Tensioners

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.

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

The Leaf Tensioner consists of a minimum of two leafs. The leaf itself varies in thickness depending on the tension required.

Thicknesses vary from 0.08 mm to 0.20 mm. Most of the types available have a surface treatment of hard chrome with a minimum of 5 um up to 12 um, to increase the life of the leaf.

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

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. Mainly used at the input side of a weft feeder.

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.
