Definitions

  • the invention relates to a knife slot cover on a cutting and transport roller of a winder according to the preamble of claim 1, and a method according to the preamble of claim 11.
  • the cutting blade passes through a generally slot-shaped opening in the lateral surface of the cutting and transport roller and thus cuts through the material webs which rest on the lateral surface of the transport roller.
  • said webs of material can be damaged when they come into contact with the slot-shaped opening.
  • the invention is therefore based on the object to minimize the resulting damage or to avoid altogether.
  • the object is achieved by a device or a method having the features of claim 1 or 11, wherein the slot-shaped opening in the lateral surface of the transport roller is closed when the knife is in its rest position in the interior of the roller.
  • closure of the knife forms a part of the circumferential surface of the transport roller in the closed position.
  • FIG. 1 shows a section through the region of a web guide roll 1 according to the invention, in which the cutting process takes place.
  • the outer jacket In order to allow the knife 4, which is supported and moved by a knife carrier 5, to pass through the outer jacket 2, the outer jacket has a knife passing slot 3.
  • the outer jacket 3 consists of a steel jacket 8 and a rubber coating 9.
  • the cutting edge 10 of the blade 4 protrudes in the radial direction beyond the peripheral surface 11 of the web guide roller and cuts through the Film web 12.
  • the web guide roller has end covers, one of which 13 can be seen in the figure.
  • a closure 6 formed as an inflatable tube 6, which is not inflated in Figure 1 and the knife 4 allows passage through the knife slot.
  • hoses may be mounted in the blade passage slot 3, which follow one another, for example, in the axial direction (z) of the roller.
  • FIG. 3 once more schematically shows a device according to the invention, in which a slider 15 closes the slot-shaped opening 3 in the shell of the roller.
  • the slider 15 has a projection 24 which with little play in the guide groove 17, which is located in the shell of the roller, can slide. In this way, the slider is held and guided.
  • the projection 24 is articulated on the pull-push rod 25.
  • the pull-push rod is in turn connected to the articulation 20 with the lever 19.
  • the lever 19 is attached to the fulcrum 16. Furthermore, the lever is connected via the articulation 21 with the piston 27 of the pneumatic cylinder 28.
  • the pneumatic cylinder 28 transmits over its piston 27, the lever 19 and the pull-push rod 25 force on the slider 15 and.open and closes in this way the knife slot.
  • a buffer of flexible material 23 such as rubber is provided in the embodiment shown between the slide and the lateral surface. If necessary, such a buffer may contain cavities or recesses 26 so as not to project beyond its bulge in the radial direction over the steel shell of the roll.
  • the entire cutting or knife guide mechanism of the cutting and transport roller is not the subject of the present invention and is therefore only outlined here.
  • FIG. 4 is an overall view of a cutting and transporting roller 1 according to the invention, which is shown cut here. Again, the actual cutting mechanism is sketched only in FIG. 3 by the box of the cutting device 22, the knife 4 and the knife carrier 5.
  • the knife slot 3 is closed again with a hose 7.
  • the hose 7 can be inflated or vented through the flexible supply line 14.
  • Devices that provide the required compressed air, or lead into the interior of a roller are also known and are therefore not shown at this point.
  • the roller can rotate in both directions about the roller axis 29, which is indicated by the curved arrows ⁇ and - ⁇ , which also indicate the direction of the angular coordinates used for the description.
  • the angle coordinates ⁇ clamp together with the also on the basis of a
