At the ITMA in Milan, the new KAST ECR warp tension control is presented to the trade for the first time. The idea behind the KAST ECR is that the warp beam does not need to be driven, as the warp tension is sufficient and the warp beam only needs to be braked.
In the past, this was often achieved with weight-loaded rope brakes. As the warp beam diameter decreased, the weights had to be changed. In order to avoid this non-value-adding work and at the same time to keep the warp tension constant from the full to the empty beam, the KAST ECR was developed.
The warp tension is monitored by load cells or distance sensors. Either the tension or the position of the pendulum is displayed on the control panel.
Many functions of the BLDC have also been adopted for this new control.
