ASSEMBLY WINDING RANGE
The sturdy and reliable electronic yarn guided MATRIX B machines equipped with their new winding platform have been designed to reach high winding speeds up to 1.500 m/min (mechanical speed up to 1.900 m/min) and to guarantee an optimal yarn laying and a perfect package formation that assure a uniform yarn tension during the subsequent twisting phases, so as to allow an unwinding without tears.
The bobbin formation of the MATRIX B machines is undoubtedly one of their strong points.
Fadis has introduced in 2015 the “MATRIX” electronic yarn guided winding platform where the function of the yarn guide is carried out by an electronic yarn guide system controlled by a step motor, piloted and controlled by one inverter for each single spindle.
Thanks to this unique characteristic it is possible to modify the crossing angle between 8° and 25° to displace the crossing point of the yarn coils at various winding levels, thus avoiding patterning problems (anti-pattering) and to change the crossing angle according to the bobbin diameter during the package formation thus obtaining packages with excellent unwinding characteristics during the subsequent twisting phases.
This technology, combined with the pneumatic control of the take-up arm that can be adjusted either for increasing or decreasing the pressure of the bobbin on the take-up arm, ensures an excellent unwinding and allows to obtain bobbins for twisting with a compact, density and weight up to 15% higher than with normal assembly winding machines.
These characteristics ensure a substantial increase of productivity and an excellent performance during the twisting process.
