    摘要: When an open end spinning machine is stopped, a fiber supply to a spinning rotor is first stopped and thereafter, substantially simultaneously with stoppage of both a yarn take-up roller and a yarn winding roller, a yarn end is held by a yarn holding device at a time when it still remains in a region which undergoes the suction effect of a subatmospheric pressure produced in the spinning rotor. The spinning rotor is subsequently stopped. On starting, the holding of the yarn end by the yarn holding device continues even after restarting of the spinning machine until the subatmospheric pressure produced in the spinning rotor reaches substantially the same value as that produced during a normal spinning operation. Therefore, there is prevented any snarling phenomenon, resulting in a greatly increased success rate in the operation of connecting yarn ends on re-starting of the spinning machine.

    摘要: According to this invention, a spinning rotor is increased in speed until it reaches a predetermined higher speed beyond a lower speed region and then decreased in speed until it falls within the lower speed region, in which a yarn ending is effected. Thereafter, the speed of the spinning rotor is increased to a normal spinning speed beyond the predetermined higher speed. During rotation of the spinning rotor at the predetermined higher speed, sufficient subatmospheric pressure is produced in the spinning rotor to stretch out the yarn end thereby to prevent the yarn end from being snarled. Also, during this higher speed rotation of the spinning rotor, sufficient fibers in the spinning rotor can be collected in a maximum diameter portion in the spinning rotor to be connected with the snarl-free yarn end in a favorable condition. The period of time, during which the speed of the spinning rotor is decreased from the predetermined higher speed and falls within the lower speed region, is relatively short being in the order of a few or several seconds. Therefore, it will be understood that there is no fear that both the yarn end and the remaining fibers are restored to their initial state during that period of time.

    摘要翻译: 根据本发明,旋转转子的速度增加,直到其超过低速区域达到预定的较高速度,然后降低速度,直到其落入进行纱线结束的低速区域内。 此后,将纺丝转子的速度提高到超过预定的较高速度的正常纺丝速度。 在旋转转子以预定的较高速度旋转时,在纺丝转子中产生足够的低于大气压的伸出纱线端部,从而防止纱线端部嘶嘶响。 此外,在纺丝转子的这种较高速度的旋转中,纺丝转子中的足够的纤维可以收集在纺丝转子的最大直径部分中,以在有利的条件下与无卷曲纱线端部连接。 纺纱转子的速度从预定的较高速度降低并落在低速区域内的时间段相对较短,为几秒或数秒左右。 因此,应当理解,在该时间段内,纱线末端和剩余的纤维都不会恢复到初始状态。

    摘要: An open end spinning machine includes a plurality of spinning units. Each spinning unit includes a first yarn breakage sensing device assuming a yarn sensing, operative position, in which it contacts the yarn, when the spinning unit is in a normal spinning operation and an inoperative position, in which it is not in contact with the yarn, when the spinning unit is in a transient condition either from or to the normal spinning operation, and a second yarn breakage sensing device assuming a yarn sensing position at least when the spinning unit is in the transient condition. Upon occurrence of yarn breakage when the spinning unit is in the transient condition, such breakage is detected by the second yarn breakage sensing device and the supply of fibers to the associated spinning unit is interrupted by the second yarn breakage sensing device.
