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。

摘要： Equipment for leading a web threading tail in a paper machine has at least two sequential surfaces (11) in the direction of travel of the web threading tail (10), between which a nozzle (12) is arranged to form a directed air blast and thus to transport the web threading tail (10). The equipment has an element (13) in which an exhaust zone (20) is arranged in the surface (11) before the nozzle (12) in the direction of travel of the web threading tail (10), for leading air away from the element (13) between the web threading tail (10) and the surface (11).

摘要： An arrangement in the on-line finishing of a paper machine, which includes at least one finishing stage (12, 13) for the paper web produced, has cutting equipment (16) for forming the tail as well as tail threading equipment (15) for carrying the tail through the finishing stage (12, 13). At the end of the finishing stage (12, 13) there is a draw point (24), through which a carrier rope system (17) included in the tail threading equipment (15) is adapted to pass. The draw point (24) is formed between one cylinder (28) and a wire (29) arranged in contact with it for forming a single-contact draw point.

摘要： Method and apparatus for guiding a web of paper or board or, alternatively, an edge strip sheared therefrom, in a paper machine or finishing equipment, the method being particularly suited for threading the web tail or edge strip through the machine in conjunction with a production shutdown or after a web break. According to the invention, the web (6) or its tail sheared from the web so as to form an edge strip is supported electrically by means of taking surfaces or electrodes (3, 5) disposed on opposite sides of the web (6) to different potentials. Particularly advantageously, the web (6) or the edge strip can be adhered to a roll (16), a belt (7) or a wire by taking said support element to a lower potential and disposing a higher-potential electrode (5) or a number of electrodes to the opposite side of the web.

摘要： The invention relates to a method in tail threading, in which a lead-in strip, tail (T) separated from the edge of a paper web is guided between two elongated mobile means in a paper web conveying machine and transferred forward between these two means along a given portion in the machine direction of the machine. The mobile means are belts (1, 2) between which the tail is transported. The neutral axes (N) of the belts (1, 2) are substantially on the same level.
