Embodiment 1
[0019] A method for processing broken yarns in the spinning process of ring-spun spun yarns. The method of ring-spun spun yarns is used to deal with the broken ends in the spinning process. Yarn, pass or hang the lead yarn through the traveler 6, wind the end of the lead yarn close to the traveler 6 on the bobbin 5 or the bobbin 8 according to the direction of spinning, and quickly pass the other end of the lead yarn upward or upward. Wind into the yarn guide hook 4, connect with the whisker 3 sent out between the front roller 2 and the top roller 1, and continue spinning.
[0020] Said winding one end of the yarn on the bobbin 5 or the bobbin 8 is the same as when the ring spinning spun yarn is wound on the empty bobbin on the spindle. After doffing, when starting a new doffing yarn, the unreserved spindle needs to be reworked by the stopper worker. When the stopper worker starts to start the thread, the unrefined yarn is usually hung on the traveler and the end is placed on ...
Embodiment 3
[0027] The difference between this embodiment and Embodiment 2 is that: when the yarn breakage of the compact spinning ring spinning frame is used, the "top roller" method is still used when the yarn feeding end close to the yarn guide hook is connected to the whisker. In the case of hooking, the roller closest to the yarn guide hook and the matching top roller need to be wound. Due to the compact spinning device, in this case, the yarn needs to be fed between the lattice ring and the matching top roller.
Embodiment 4
[0029] The difference between this embodiment and Embodiment 2 is:
[0030] The automatic device is used to complete the processing after the broken yarn of the ring spinning spun yarn. In order to facilitate the design of the automatic device, the processing sequence after the broken end of the ring spinning spun yarn is as follows: after the spun yarn is broken, a section of yarn is drawn out first, and after the traveler 6 is found, the yarn is taken out. 9. Pass through or hang into the traveler 6, and then wind the yarn 9 around or pass through the yarn guide hook 4. These two steps do not have strict requirements on the required time. Then, wind the end of the yarn 9 close to the traveler to the On the bobbin 8 or the bobbin 5 (the process time is not very certain, but it can be detected whether the lead-in is wound on the bobbin or bobbin), once the lead-in 9 is wound to the cop 8 or the bobbin at the end near the traveler 5, then within a short time (for example, 0.1 t...
