    • Apparatus for handling yarn ends during a donning operation on a textile machine wherein in each operation unit, a yarn package is formed on a bobbin rotatably held by a cradle and rotated by the friction roller of a take-up mechanism. Just before or after doffing a full yarn package from the take-up mechanism, a yarn passage is formed by a yarn which is continuously supplied from the operation unit at a position in front of a part of the peripheral surface of the friction roller which the yarn passes over during the normal take-up operation. A fresh bobbin urges the yarn of the yarn passage toward the friction roller and then the fresh bobbin held by the cradle is rested on the friction roller. The yarn connected to the full yarn package is severed during the operation.
    • 一种用于在纺织机上进行穿刺操作时处理纱线端部的装置,其特征在于,在每个操作单元中,纱线卷装形成在由托架可旋转地保持并由卷取机构的摩擦辊旋转的筒管上。 在从卷取机构落纱整个纱线卷装之前或之后,纱线通过纱线形成,该纱线在摩擦辊的周面的一部分的前面的位置从操作单元连续供给, 纱线在正常的卷取操作期间经过。 新鲜的纱管将纱线通道的纱线推向摩擦辊,然后由托架支撑的新鲜纱管放置在摩擦辊上。 在运行过程中,连接纱线纱线的纱线被切断。

    • 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.
    • 当开放式纺纱机停止时,首先停止对纺丝转子的纤维供给,然后在纱线卷取辊和纱线卷绕辊停止的同时基本同时,纱线端部由纱线保持装置 此时它仍然保留在经受在纺丝转子中产生的低于大气压的吸力作用的区域中。 纺纱转子随后停止。 起动时,纱线保持装置的纱线端部的保持继续,即使在纺纱机重新起动之后,直到在纺丝转子中产生的低于大气压的压力达到与正常纺丝操作期间产生的大致相同的值。 因此,防止发生嘶嘶声现象,导致纺纱机再起动时连接纱线端部的操作成功率大大提高。
