1.Tensioning Brake Device

Tensioning device, a device to detect thick spots or slubs in the yarn & a stop motion which causes the winding to stop in the case of a yarn break or the depletion of a supply package. The yarn is directed into this zone by a guide.

2.Functions of Tensioning Device:

To allow the maintenance of proper tension in the yarn in order to achieve a uniform package density.
The tensioning device also serves as a detector for excessively weak spots in the yarn which break under the added tension induced by the tension device.

3.Effects of Tension Variation:

Too high tension may damage the yarn whereas too low tension can lead a unstable packages which will not unwind cleanly. In case of manmade fiber high tension can cause molecular change which affects the dye ability, so that variations in tension ultimately show as apparently random variation in color shading. In case of winding staple yarns, yarn tension may break thin place of yarn. • Cost-effective technique for complex designs
• Ability to produce net or near-net shape parts
• Very tight tolerance control
• Low-cost, high-volume manufacturing runs.

3.Influence the Choice of Tensioning Device::

1. The device must be good quaility 2. It must be easily threaded.
3. It must neither introduce nor magnify tension variations.
4. It must not introduce difference in twist.
5. It must not be affected by wear.
6. It must be easily adjustable.
7. It must not be affected by presence of oil or dirt.
8. It must not encourage the collection of dirt & lint.
9. It must be capable of easy cleaning.
10. The loom surfaces must be smooth enough
11. Different kind of size is available
