Piecing method of a piecing apparatus on a ring spinning machine having a plurality of spinning stations at which a roving emerges from delivery rollers of a drawing frame and is twisted into a thread by means of a traveler and a rotating cop and wound onto the cop, wherein, in the event of thread breaks, the piecing apparatus automatically creates a piecing, in which a thread end (14, 14') is connected to the roving emerging from the delivery rollers and the spinning process is then continued, and wherein optionally according to - procedure a), the thread end of the broken thread is sought, the found thread end is detected and used for piecing, in order to obtain a cop without thread interruption, or - procedure b), an auxiliary thread from a thread supply is fastened to the cop, then said auxiliary thread is separated in order to obtain a thread end fastened to the cop, and said thread end is used for piecing, in order to obtain a cop having thread interruption, wherein, depending on the utilization of the piecing apparatus and/or on the probable prospect of success of procedure a), it is selected whether the thread end (14, 14') is provided according to procedure a) or b), wherein it is assumed that procedure a) takes more time than procedure b), characterized in that procedure b) is selected if the number of spinning stations waiting for the piecing apparatus exceeds a predetermined number. wherein, in the event of thread breaks, the piecing apparatus automatically creates a piecing, in which a thread end (14, 14') is connected to the roving emerging from the delivery rollers and the spinning process is then continued, and wherein optionally according to - procedure a), the thread end of the broken thread is sought, the found thread end is detected and used for piecing, in order to obtain a cop without thread interruption, or - procedure b), an auxiliary thread from a thread supply is fastened to the cop, then said auxiliary thread is separated in order to obtain a thread end fastened to the cop, and said thread end is used for piecing, in order to obtain a cop having thread interruption, wherein, depending on the utilization of the piecing apparatus and/or on the probable prospect of success of procedure a), it is selected whether the thread end (14, 14') is provided according to procedure a) or b), wherein it is assumed that procedure a) takes more time than procedure b), - procedure a), the thread end of the broken thread is sought, the found thread end is detected and used for piecing, in order to obtain a cop without thread interruption, or - procedure b), an auxiliary thread from a thread supply is fastened to the cop, then said auxiliary thread is separated in order to obtain a thread end fastened to the cop, and said thread end is used for piecing, in order to obtain a cop having thread interruption, wherein, depending on the utilization of the piecing apparatus and/or on the probable prospect of success of procedure a), it is selected whether the thread end (14, 14') is provided according to procedure a) or b), wherein it is assumed that procedure a) takes more time than procedure b), characterized in that procedure b) is selected if the number of spinning stations waiting for the piecing apparatus exceeds a predetermined number.
