    • To equalize yarn tensions in a normal winding mode and a yarn switching mode to each other, when a yarn take-up operation is carried out by a yarn winder including a turret member 1 rotatably held on a machine frame (not shown) and rotatably carrying two spindles 2, 3 thereon, a contact roller 4 to be brought into contact at a predetermined pressure with a yarn layer wound on a bobbin 30 mounted to the spindle 2, 3, spindle-driving induction motors 5, 6, and a contact roller-driving induction motor 7, at least of the surface speed of the contact roller 4 and a frequency of current for driving the contact roller-driving motor 7 is controlled in a programmed manner in accordance with a normal winding mode, a yarn switching mode wherein a yarn is switched from a full bobbin to an empty bobbin and a soft-touch winding mode wherein the contact roller is brought into soft contact with the empty bobbin.
    • 为了使正常卷绕模式和纱线切换模式下的纱线张力相等,当通过包括可旋转地保持在机架(未示出)上的转塔构件1的纱线卷绕机进行纱线卷取操作并且可旋转地携带 两个主轴2,3,接触辊4以预定的压力与卷绕在安装在主轴2,3上的绕线管30上的纱线层接合,主轴驱动感应马达5,6和接触辊 驱动感应电动机7,根据正常卷绕模式,以编织方式控制接触辊4的表面速度的至少一部分和用于驱动接触辊驱动电动机7的电流频率,纱线切换模式,其中 纱线从全筒管切换到空筒管,以及软接触卷绕模式,其中接触辊与空筒管软接触。
