The Itema Electronic Weft Brake: the ideal solution in case of delicate and weak yarns

The Itema Electronic Weft Brake allows to optimize the braking force of each weft insertion phase.
It is the ideal solution in case of low tenacity weft yarns, such as wool, that need different treatment at each stage of the insertion.

 

 

 

Programmable directly from the loom console, the setting is easy and intuitive thanks to the simple and effective dedicated page:

 

The Itema Electronic Weft Brake – specifically designed to ensure different braking areas during the weft insertion cycle – guarantees effective and precise operations:

• each pick has been divided in seven stages thus allowing to set different braking force for each stage (values from 0% to 99%)
• each stage follows a predefined order (the end of one stage corresponds to the beginning of the next one) thus meaning that the weaver needs to set 5 braking force values (the first and the last values – 0°and 330° – are preset and fixed).

An example of braking force setting possible with the Itema Electronic Weft Brake is shown here below:

Moreover, when weaving without tuck-in devices, the Itema Electronic Weft Brake improves the selvedge formation leading to a reduced weft waste on the right side.
