Definitions

  • the invention relates to a device for guiding a paper web, in particular a cigarette paper web unwound from a bobbin in cigarette manufacture.
  • Cigarette paper webs unwound from the bobbin are guided into the so-called format trough, in which they encase the prepared tobacco filling to form a cigarette rod.
  • the paper bobbins are not always wound completely in the same plane, so that there are axial displacements of the paper web and consequently inaccuracies in its further processing.
  • Known facilities contain e.g. B. an elongated flat trough which passes through the paper web. The trough edges above the guide surface are bent back to create a partially closed guide trough. The axial adjustment of the continuous paper web is carried out by the lateral displacement of the trough with the help of set screws guided.
  • guide rollers are also used to compensate for the position of the continuous paper web, on the surface of which a trough is formed for the orientation of the position of the continuous paper web.
  • the paper web unwound from the bobbin can be rotated by 90 ° by means of guide rollers and at the same time rotated through a right angle in the machine, so that the bobbin axis in the machine runs in the direction of the paper web fed to a format trough.
  • the object of the invention is to provide a device for guiding a paper web which avoids the disadvantages of the prior art and which enables the position of the running paper web to be automatically corrected in a technically simple manner without manual intervention.
  • the device for guiding the paper web according to the invention is formed by the plate which is accommodated in the middle of the surface on the bolt and on its two opposite sides on the opposite surface the passage for the paper web through the inlet slide in the shape of the trough and the outlet slide is formed, which is formed by the wall with the U-shaped cutout, or the passage for the paper web is formed by the inlet slide and the outlet slide in the form of the trough.
  • the removal of the vertical edges of the cutout of the exit slide is equal to the width of the paper web, reduced by 8 to 12% of the width of the paper web.
  • the bolt on which the plate is housed is rotatably mounted in the holder, or the bolt on which the plate is housed is fixedly mounted in the holder.
  • the advantage of the device according to the invention lies primarily in the fact that the movement of the paper web can be regulated continuously by means of a simple device, especially in the case when the disk of the bobbin is not straight in the vertical direction on the axis, which in turn means the axially undulated Movement of the paper web has, so that disturbances arise on the further mechanism of the cigarette machine.
  • the movement of the paper web according to the need e.g. B. to regulate by regulating screws, but the regulation is carried out continuously by the own device without the operator intervention.
  • the device for guiding and shaping a paper web 7 contains a rectangular plate 1, which is fastened with its middle part on a bolt 2. On the face of the plate 1 opposite the bolt 2, two upwardly projecting sliders 3, 4 for guiding the paper web 7 are attached to the ends.
  • the inlet slide 3 arranged on the inlet side of the movement of the paper web 7 is designed as a trough.
  • the outlet slide 4 arranged on the outlet side of the paper web is a U-shaped profile, the central web of which is attached to the plate 1 and the two legs of which project vertically upward.
  • the pin 2 can be rotated in a holder 5, as shown in FIG. 3, or is fixedly mounted in a clamp in order to enable the plate 1 to be rotated with respect to the axis of the continuous paper web.
  • the paper web 7 unwound from the bobbin and guided to the processing mechanisms of the cigarette machine is arched lengthwise in the trough-shaped inlet slide 3 as it passes through the guide according to the invention and formed into an arcuate trough.
  • the paper web 7 also runs through the U-shaped outlet slide 4 between its vertical legs, the spacing between which is smaller than the width of the paper web 7, namely by about 8 to 12%, preferably 10%, of the width of the paper web 7.
  • the pivoting mounting of the pin 2 in the holder 5 pivots the inlet side of the plate 1 with the trough-shaped inlet slide 3 around the pivot pin 2 and the paper web 7 runs between the vertical legs the outlet slide 4 by the guide device in the desired orientation to the following processing units of the machine.
  • the bolt 2 which carries the plate 1 with the inlet slide 3 and the outlet slide 4, in the holder 5, z. B. detectable by a clamp, not shown, so that the central axis of the guide device automatically adjusts to the axis of the paper web 7 and this position is secured by tightening the clamp.
  • 3 can also be pivoted about its bolt shown on the left and fixed in the correct position.
