Yarn winding machine SINCRO PLUS B

precision

The SINCRO PLUS B - BL - B FT electronic yarn guided precision crossing machines have been designed for winding speeds as high as 1.750 m/min (mechanical speed up to 2.250 m/min). With the SINCRO PLUS B - BL - B FT electronic yarn guided, precision crossing assembly winding machines it is possible to attain the main object of this production process, that is to obtain bobbins with the highest possible density and the lowest number of breaks, so as to increase the efficiency during the subsequent twisting phase. The precision crossing technology with positively driven bobbin allows to produce packages with a perfect and controlled yarn laying without any patterning problem. 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 compactness, density and weight up to 25% higher than with normal assembly winding machines (for ex. with grooved drum assembly drivers). These characteristics ensure a substantial increase of quality and an excellent performance during the twisting process. This positively driven bobbin technology allows to produce perfect bobbins without having to exercise a high pressure of the bobbin on the support roller. This has the double advantage of producing bobbins with any desired compactedness and density, but most of all to avoid the yarn abrasion problem (pilling/hairiness) on the support roller, and thus to be able to process all types of extra fine yarns.
