摘要： A threading device and a method for threading a tail of a web, wherein, for guiding the path of a tail separated from a full-width web in a paper machine or a paper finishing device, the threading device comprises a suction channel, placed at least partly in a paper machine portion and provided with a reduced pressure for gripping the tail, and transfer means for transferring the suction channel in the portion of the paper machine and simultaneously for releasing the tail to the portion. In the method for threading of the tail, before threading the full-width web through a portion in a paper machine, the tail is separated from the web, the tail is cut, and the tail is conveyed in the portion of the paper machine, after which the full-width web following the tail in a continuous manner is conveyed to the portion, by providing a reduced pressure in a suction channel, by transferring an inlet opening of the suction channel close to the tail separated from the web, by transferring the tail into the suction channel by means of the reduced pressure prevailing therein, and by releasing the tail to the portion of the paper machine by transferring the suction channel and particularly the inlet opening in the direction of the portion of the paper machine.
摘要翻译：一种穿线装置和一种用于穿线的尾部的方法，其中，用于引导在造纸机或纸整理装置中从全宽幅纸分离的尾迹的路径，所述穿线装置包括：吸入通道，至少部分地在造纸机部分中并具有用于夹紧尾部的减压力以及用于在造纸机的部分中传送吸入通道并同时用于将尾部释放到该部分的转印装置。在用于穿过尾部的方法中，在将全幅幅材穿过造纸机中的一部分之前，尾部与纸幅分离，尾部被切割，并且尾部在造纸机的部分中被输送，之后，通过在抽吸通道中提供减压，通过将吸入通道的入口靠近从纸幅分离的尾部传送而将跟随尾部的全幅幅连续地传送到该部分，通过转印通过其中存在的减小的压力将尾巴进入吸入通道，并且通过沿造纸机部分的方向传送吸入通道，特别是入口，将尾部释放到造纸机的部分。
