    • A method and an apparatus for conveying empty bobbin tubes through a channel member which extends longitudinally along a plurality of working units of an open-end spinning, winding, yarn texturing or similar machine. The apparatus of the invention includes a transporting member which is operatively mounted on the machine so as to move in a stepwise manner along the plurality of working units of the machine. The machine includes a bobbin supply and withdrawing station opposite each working unit. The transporting member is adapted to move in a stepwise manner from one bobbin withdrawing and supply station to the next adjacent one. The apparatus further includes a channel member extending longitudinally along the plurality of working units. A plurality of empty bobbin tubes are disposed in the channel member end-to-end so as to form a column. The transporting member has a carrier member extending therefrom towards the channel member. The carrier member is adapted to push the column of empty bobbin tubes along the channel member when the transporting member moves from one bobbin supply and withdrawing station to the next one. The transporting member is also adapted to exchange a fully wound bobbin by an empty bobbin which is removed from the channel member.
    • 一种用于通过通道构件输送空筒管的方法和装置,所述通道构件沿着开口纺纱,卷绕,纱线织纹或类似机器的多个工作单元纵向延伸。 本发明的装置包括可操作地安装在机器上以沿着机器的多个工作单元逐步移动的传送部件。 该机器包括在每个工作单元对面的筒管供应和抽出站。 输送构件适于从一个筒管抽出和供给站逐步移动到下一个相邻的一个。 该装置还包括沿多个工作单元纵向延伸的通道构件。 多个空的筒管被配置在通道构件中,以便形成柱体。 传送构件具有从其朝向通道构件延伸的载体构件。 承载构件适于当输送构件从一个线筒供应和抽出站移动到另一个时,沿着通道构件推动空筒管的列。 输送构件还适于通过从通道构件移除的空筒管来更换完全卷绕的筒管。

    • A method of and an apparatus for piecing yarn in open end rotor spinning units. The returning of the yarn end into the spinning rotor for piecing is performed in two stages, in the first of which the yarn is stopped immediately upon breakage within the sucking range of the spinning rotor, and is brought immediately thereafter into a withdrawal chamber in which the yarn end is retained. In the second stage the yarn end is separated and deposited in said withdrawal chamber, and the new yarn end is introduced by further reverse motion into the spinning rotor. The apparatus has a withdrawal chamber interposed between the inlet of the withdrawing channel and a cutting mechanism. In one embodiment said chamber is connected to the withdrawing channel, opposite which there is mounted a nozzle connected to a controlled pressure air source. In another embodiment there is provided a nozzle communicating with the withdrawal chamber, said nozzle being connected to a controlled source of underpressure.
    • 用于在开放式转子纺纱单元中接头纱线的方法和装置。 将纱线端部返回到用于接头的纺丝转子中进行两个阶段,其中第一个纱线在旋转转子的吸入范围内立即停止,并立即被引入到抽出室中,其中 纱线端部被保持。 在第二阶段中,纱线端部被分离并沉积在所述抽出室中,并且新的纱线端部通过进一步的反向运动引入纺丝转子中。 该设备具有介于抽出通道的入口和切割机构之间的抽出室。 在一个实施例中,所述腔室连接到抽出通道,与之相对的是安装有与受控压力空气源连接的喷嘴。 在另一个实施例中,提供了一个与抽出室连通的喷嘴,所述喷嘴连接到受控的负压源。

    • The invention relates to an apparatus for the spinning-in of yarns in an open-end rotor spinning unit. The apparatus includes a spinning-in device for returning yarn end through a take-off duct into the spinning rotor, a severing device for shortening the yarn end to a predetermined length, and a withdrawing duct which communicates with the take-off duct and which is designed, on the one hand, for holding the yarn end by the action of a vacuum which, in the contact region of the two ducts, exceeds the working vacuum in the take-off duct, and, on the other hand, for withdrawing the severed yarn end. In accordance with an essential feature of the invention, at least one air nozzle opens into the withdrawing duct which during both spinning and spinning-in processes is connected to a subatmospheric pressure source, which nozzle is designed for introducing a fresh yarn end into the take-off duct by a controlled air outflow in a particular phase of the spinning-in process. The invention expediently utilizes the subatmospheric pressure air for both the spinning-in process and the withdrawal of impurities from the yarn in the take-off duct of the spinning rotor during the spinning process.
    • 本发明涉及一种用于在开放式转子纺纱单元中纺纱的装置。 该装置包括用于将纱线端部通过引出管道返回到纺丝转子中的纺纱装置,用于将纱线端部缩短到预定长度的切断装置和与取出管道连通的抽出管道, 一方面设计用于通过在两个导管的接触区域中超过起飞管中的工作真空度的真空的作用来保持纱线端,另一方面,为了抽出 切断纱线末端。 根据本发明的基本特征,至少一个空气喷嘴通向抽出管道,在两个纺纱和纺纱过程中,两个喷嘴连接到一个低于大气压的压力源,该喷嘴被设计用于将新鲜的纱线端部引入到卷取装置 在纺纱过程的特定阶段通过受控的空气流出。 本发明在纺丝过程中方便地利用低于大气压的空气进行纺丝过程和纺丝转子的送出管中的纱线中的杂质的抽出。
