    • An open-end spinning device with a fiber feeding channel which extends from a housing with a rotating opening roller to a spinning element. The fiber feeding channel comprises two channel sections which can be moved towards each other and can be brought into alignment with each other. The first channel section is located in an insert of the housing and is capable of axial movement in the housing. The insert is urged by an elastic element in the direction of the second channel section and is covered by a screen on its end towards the interior of the housing, at least on the downstream side (with reference to the rotational direction of the opening roller). A seal is located between the insert and the housing.
    • 一种具有纤维馈送通道的开放式纺纱装置,其从具有旋转打开辊的壳体延伸到纺丝元件。 纤维馈送通道包括两个通道部分,两个通道部分可以彼此相对移动并且可以彼此对准。 第一通道部分位于壳体的插入件中并且能够在壳体中轴向移动。 插入件由弹性元件沿第二通道部分的方向推动,并且至少在下游侧(相对于打开辊的旋转方向)在其端部朝向壳体的内部被屏幕覆盖, 。 密封件位于插入件和外壳之间。

    • A winding process for winding yarn into a cross-wound bobbin in the textile machine includes depositing the yarn on a bobbin in a transversing stroke by a transversing movement of a yarn guide. The process includes intermittently decreasing the traversing stroke from a maximum value to a minimum value and then increasing the value of the traversing stroke from the minimum value back to a relatively constant maximum value and holding the stroke at the maximum value for a predetermined period of time. The traversing frequency of the yarn guide is decreased to a relatively constant minimum value substantially simultaneously with the increasing of the traversing stroke from the minimum value back to the relatively constant maximum value. The traversing frequency is maintained at the constant minimum value for a predetermined period of time. The traversing frequency of the yarn guide is then increased from the constant minimum value after the predetermined period of time. The duration of the decreasing of the traversing frequency of the yarn guide is shorter than the duration of the maximum value of the traversing stroke.
    • 用于将纱线卷绕到纺织机中的交叉卷绕筒管中的卷绕工艺包括:通过纱线引导件的横向移动将纱线沉积在横向行程中的纱管上。 该过程包括将运行行程从最大值间歇地减小到最小值,然后将运行行程的值从最小值增加到相对恒定的最大值,并将行程保持在最大值预定时间段 。 纱线引导件的运行频率与从最小值返回到相对恒定的最大值的运行行程的增加基本上同时减小到相对恒定的最小值。 运行频率在一定的时间内保持在恒定的最小值。 然后,在预定时间段之后,导纱器的运行频率从恒定的最小值增加。 导纱器的运行频率下降的持续时间短于运行行程的最大值的持续时间。

    • A spinning rotor of an open-end spinning device is slowed down for piecing to a low rotational piecing speed and is then accelerated to the operating speed. For this purpose, the spinning rotor or an element in driving connection with it is presented a drive transmission device from a service unit by means of which the spinning rotor can be switched from normal production speed to a reduced piecing speed and back. In this process, the drive transmission device can be driven either by a driving apparatus installed on the service unit or by a drive belt extending within spinning machine. The driving apparatus mounted on the service unit is connected to a control device for the control of the evolution of the rotational speed of the spinning rotor. The spinning rotor is driven according to a rotational speed course controlled by means of a program applied by the control device during the time when its rotational speed deviates from its operating speed.
    • 开放式纺纱装置的旋转转子减速以接合到低的旋转接头速度,然后被加速到操作速度。 为此,旋转转子或与其驱动连接的元件由来自服务单元的驱动传动装置提供,通过该驱动传动装置,纺丝转子可以从正常生产速度切换到降低的接头速度和背面。 在该过程中,驱动传动装置可以由安装在维修单元上的驱动装置或由纺纱机内延伸的传动带驱动。 安装在维修单元上的驱动装置连接到用于控制旋转转子的转速演化的控制装置。 旋转转子根据转速进行驱动,转速是通过控制装置在其转速偏离其运行速度时施加的程序控制的。
