摘要:
The invention relates to an automatic turret type yarn winding device. The automatic bobbin changeover process involves winding of yarn on a bobbin, followed by rotation of the turret to bring an empty bobbin into the winding position. Pressure rollers are provided to ensure consistent and accurate winding. The accurate relative positioning of the bobbins and pressure rollers is important. Wear and tear and particulate dust may cause malfunctioning of winder systems which may affect accuracy of turret rotations and relative positioning of the bobbins and pressure rollers, especially when the turret rotation during bobbin changeover stage is done in a single rotation. The invention provides a device and a method to position spindle precisely in turret type automatic winder, especially to identify correct stationing position of turret spindle after reverse movement post doffing. It involves, during the bobbin changeover process, the step of rotating the turret in at least two discrete rotational movements carri
