    • The present invention provides a detection system (20; 60; 80) for a winding unit (8) of a thread (15) around a spool (2), comprising a traveller element (12, 62) suited to receive the thread (15) to be wound and suited to slide on a guide element (11; 71) arranged along a closed path around the spool (2). The detection system (20; 60; 80) being suited to detect the passage of the traveller element (12; 62) on the basis of a variation of intensity of a magnetic field, comprises means (12; 72; 92) suited to generate a magnetic field, means (12, 72; 92) pertaining to the winding unit (8). The invention also concerns a ring spinning machine (1) of the type comprising a winding unit (8) of a thread around a spool (2) and a detection system (20; 60; 80) for the winding unit (8).
    • 本发明提供了一种用于围绕卷轴(2)的螺纹(15)的卷绕单元(8)的检测系统(20; 60; 80),包括适于接纳螺纹(15)的滑动元件(12,62) )被缠绕并且适合于沿着围绕卷轴(2)的封闭路径布置的引导元件(11; 71)滑动。 检测系统(20; 60; 80)适于基于磁场强度的变化来检测旅行器元件(12; 62)的通过,包括适于产生的装置(12; 72; 92) 磁场,与所述绕组单元(8)相关的装置(12,72; 92)。 本发明还涉及一种环锭纺纱机(1),其包括围绕卷轴(2)的线的卷绕单元(8)和用于卷绕单元(8)的检测系统(20; 60; 80)。
