Definitions

  • the present invention relates to a device for dividing a paper web, which is wound on a rotating drum is, for the transition of the winding process of the paper web to a rotating empty drum using a tear tape, which extends across the paper web and its free end at the empty Drum is attachable, making it helical on this is wound up and thereby divides the paper web, with a in the direction of the axis of the empty drum laterally outside it carriage adjustable transversely to this axis, on which a device is arranged to hold the tear tape.
  • this device is the conveyor for the tear tape is on a first side of the paper web and the separation process is on the other side of the paper web, there is a need the tear tape through the one extending transversely to the paper web Slide channel and in between the two drums insert the existing gap. For this, the tear tape must be sufficient Have rigidity so that this pushing movement can be carried out is. For this reason, tear tapes are used for these devices from side by side and glued together Made of paper cords.
  • a device is also known from EP 708 049 A1, in which the conveyor for the tear tape on that side the paper web on which the separation process begins. There thus the tear tape is pulled through the channel and only for empty drum needs to be promoted, it can be an essential have lower rigidity. Accordingly, for this device Tear tapes are used, e.g. from folded sheets of paper are made, having a much lower strength.
  • Tear tapes must have a high tear strength that they however, should be as thin as possible because they are on the empty drum, over which the Paper web is wound up, with those layers of the paper web, which are marked by the tear tape as a result of impressions, to constitute a committee. Since the tear tape with the committee of Paper web should be able to be fed to a reprocessing, it should be made of paper. Because the drums also have a rubber coating trained, the tear tape must also if possible be soft and as little stiff as possible. However, if these demands are fulfilled, it causes difficulties in emptying the tear tape To promote drum so that it comes to the system to the To be able to initiate the separation process.
  • the device known from US Pat. No. 4,757,950 is also on the other side of the paper web with a device for holding the Tear tape formed, which by means of a carriage to the surface the empty drum can be introduced. Once the free End of the tear tape has been attached to the empty drum, it must released by the institution from which it is held.
  • this device is for holding of the tear tape by means of two clamping jaws that can be swiveled towards each other educated. As soon as the separation process begins, the tear tape becomes from this torn out of both jaws. Since the tear tape as rigid band is formed, it holds the caused by this process Loads stood. However, once a much thinner Tear tape is used, there is a risk of it being torn out is torn from the jaws, causing the separation process of the Paper web would no longer be feasible.
  • the object of the invention is therefore based on the object the device arranged on the slide for holding and advancing of the tear tape so that tearing of the tear tape is definitely excluded.
  • the means for holding the tear tape is formed by a suction device, which by a via a Hose connected vacuum source is controllable.
  • a compressed air nozzle is also provided, through which the tear tape is movable towards the device for holding the tear tape.
  • the device for holding on of the tear tape on the sled pivotably, being pivoted relative to the carriage during the movement thereof becomes.
  • this device can be from one leg of an angle lever protrude transversely, which is rotatably mounted in its apex, the free end of the other leg being fixed in a frame Scenery is led.
  • This device is based on a cross to the two drums which the paper web is wound, extending and below the paper web arranged channel 3 which is close to the located between a drive drum 11 and the empty drum 12 Gap 10 ends.
  • a slide 31 is guided in channel 3 which the free end of the tear tape 4 from one side of the paper web is movable to the other side. This will make the free end of the Tear tape 4 in the area between the two drums 11 and 12 located gap 10 promoted.
  • a tension element 32 which at the end of the channel 3 by a Deflection roller 33 is guided.
  • a position of the carriage 31 is shown, in which it is slightly before its end position.
  • the end position of the slide 31 is shown in FIG. 2.
  • the two rollers 34 and 35 are driven, whereby the tear tape 4 is advanced. This stage is shown in Fig. 3 of the drawing.
  • a further device 5 is provided, which is supported by a frame 50 and through which the tear tape 4 is advanced to initiate the separation process. As can be seen from FIGS. 1 to 6 and 7, this further device 5 is located laterally outside the two drums 11 and 12.
  • This device 5 contains a carriage 52 which can be displaced along a fixed rod 51 and on which a holding device 6 for the tear tape 4 is pivotally mounted.
  • the carriage 52 is hydraulically, pneumatically or electrically displaceable transversely to the axes of rotation of the two drums 11 and 12.
  • an angle piece 53 is mounted on the carriage 52, which can be rotated about an axis 54 which is aligned parallel to the axes of rotation of the two drums 11 and 12.
  • a roller 55 is mounted, which is guided in a backdrop 56.
  • a beam 61 protrudes from the other end of the angle piece 53 in the direction of the axes of the drums 11 and 12 and protrudes into the gap 10 formed between the two drums 11 and 12.
  • the free end of the bar 61 is formed with suction cups 62, to which a suction line 63 connects.
  • the beam 61 is at its free end provided with three suction cups 62, which via the suction line 63 to Come into effect.
  • a blowing nozzle 66 is provided which, like 7 can be seen in particular on the tear tape 4 or on the Suction cups 62 is directed.
  • the blowing nozzle 66 is switched on and the suction line 63 leading to the suction cups 62 is connected to a vacuum source.
  • the tear tape 4 is moved toward the suction cups 62 and is grasped by them, as a result of which it is held in position by them.
  • Fig. 4 the carriage 52 is moved along the guide rod 51 in the direction of the two drums 11 and 12.
  • the angle piece 53 is pivoted clockwise by the roller 55 guided in the link 56. This stage is shown in Fig. 5.
  • the free end of the tear tape 4 which is designed with an adhesive application 41, comes into contact with the empty drum 12, as a result of which it is attached to it.
  • This stage is shown in Fig. 6.
  • the separation process is initiated by attaching the tear tape 4 to the empty drum 12, which is rotating.
