Definitions

  • the invention relates to a streak and Transfer device of a machine for manufacturing a continuous web of material, in particular Paper or cardboard web, according to the preamble of the claim 1, also a method of knocking off and transferring a threading strip inside a machine for the production of a continuous Material web, in particular paper or cardboard web, according to the preamble of claim 17.
  • FIG. 1 Facilities and procedures of those mentioned here Kind are known. They are used when starting the machine for producing a continuous Material web to introduce the web into the machine. Because of the width of the web, that too Can be 8 to 10 meters, it is practically impossible threading them in full width at the same time. Therefore, a so-called Insertion or threading strip, which also as Ribbon is cut off from the web.
  • the threading strip is much narrower than the entire material web, for example approximately 30 cm wide. This threading strip is in the machine threaded and finally pulls the material web in full width with itself. The threading process takes place, for example, when starting up the paper machine or after a web tear.
  • the threading strip runs at the beginning of a threading process together with the rest of the web free, that is, it becomes - for example, from the first drying cylinder of a dryer section of the machine for the production of a material web in the basement of the machine is removed and reprocessed fed.
  • the machine must be able to pass through it first cut off, that is cut off. Because the material web or its threading strip at the beginning of the threading process with full machine running speed respectively at most with only an insignificantly reduced speed expires, arises during the tee-off process a traffic jam, due to which another flyover of the threading strip is often problematic is.
  • a transfer and Knock-off device for a machine for processing a continuous web of material the one with the help of a lever system against the circumference a winding roller displaceable guide roller. It also has a knife for separating the Material web on. In the event of a web break, it becomes free downward web of material from a machine operator led over the leadership role. The leadership role will then be shifted and against the circumference of the winding roll on which the Material web to be wound, pressed.
  • the facility includes a leadership role with the freely running threading strips engaged can be brought and this leads to the interface. It is possible, a web congestion when knocking off to avoid the material web and a problem-free To ensure transfer of the threading strip. Furthermore, a knife to separate or Knocking off the material web provided.
  • the facility is characterized in that the leading role a clamping device is assigned. Through this interaction between leadership role and clamping device becomes the guide of the threading strip improved so that a clean cut and transfer of the threading strip guaranteed can be.
  • the clamping device comprises at least one pinch roller with the Leadership role.
  • An embodiment of the is also preferred Stripping and transfer device that itself characterized in that the rotational speed the guide roller and / or the pinch roller so adjustable is that their peripheral speed is at least is the same as the running speed of the threading strip. Because the two roles are engaged stand together, they basically rotate at the same speed. It is therefore sufficient to drive one of the two roles and the peripheral speed of one of the two rollers adjustable to choose. Due to the adjustable rotation speed can the tension of the threading strip set to a desired value be, so that a defined tee and ensures a clean transfer of the threading strip are.
  • An embodiment of the is particularly preferred Stripping and transfer device that itself characterized in that for the tee used knife is relocatable. It is with it possible to choose the knife movement so that this in the direction of the threading strip transfer direction runs. So that is through the Teeing process created free front end of the threading strip distracted in the direction in which the threading strip is to be transferred.
  • a method for Knocking off and transferring a threading strip inside a machine for making a continuous Material web suggested that the features mentioned in claim 17.
  • the procedure provides that a preferably driven Leadership in the path of movement in the basement of the threading strip running out of the machine is shifted.
  • the process is characterized by this that the threading strip before knocking off led to the tee, knocked off and to one - seen in the direction of web travel - the guide roller downstream part of the machine is transferred. Due to the defined position of the threading strip a paper jam and Problems with the transfer can be avoided.
  • An embodiment of the method is preferred, which is characterized in that the threading strip before knocking off a defined preload is subjected. This leads to another Improvement of the behavior of the threading strip when teeing off. A traffic jam can be safe avoided, so that problems with the transfer of the chipped strip end practically excluded are.

  • the one shown in FIG Functional position is the carrier device 17 pivoted upwards counterclockwise, so that the guide roller 27 and the Pinch roller 37 arranged at such a distance are that the separated from the material web 4 Threading strips between the two rolls can run into the basement 7.
  • FIG 2 shows the device 1 in its second Functional position:
  • the carrier device 17 By activating the piston-cylinder unit 25, the carrier device 17 is opposite the fixed counter bearing 19 clockwise pivoted so that the guide roller 27 in the path of movement of the scraper 9 freely in the Cellar 7 running threading strip of the material web 4 arrives. So the threading strip is deflected to the right by the guide roller 27.
  • the guide roller 27 is with such Rotational speed that driven the peripheral speed the guide roller 27 at least the The running speed of the threading strip corresponds.
