Definitions

  • Cutting device for cutting at least one edge of a conveyor belt
  • the invention relates to a cutting device for the cutting machining of at least one edge of a conveyor belt according to the preamble of claim 1 and to a conveyor belt production line with such a cutting device according to claim 10.
  • the removal of the shoot is usually done manually by a person with a cutting edge such as a blade moves laterally along the edge of the belt and thereby cuts off the shoot.
  • This process can take place between the two aforementioned manufacturing steps within the vulcanization press, while the vulcanized conveyor belt section is there.
  • the disadvantage here is that this manual cutting of the shoot can be very stressful for the person, especially at longer conveyor belts, where distances of eg up to 15 m have to be covered for a cut.
  • the person can also hold a cutting edge laterally to the belt edge, while the conveyor belt from the vulcanization press to the take-up frame or within the vulcanization press to prepare the vulcanization process of the next
  • Conveyor belt section is pulled forward.
  • the disadvantage here is that in this case the passage speed of the product usually has to be reduced in order to reduce the risk of falling for the person holding the cutting edge. This can lead to increased production times and thus increased production costs.
  • the disadvantage is overall that it can come by manually guiding the cutting edge by a person to a different quality of cutting the budding. This can result from the qualification of the person, but also from the diminishing attention of the person with increasing fatigue. This can result in both too little budding and too much belt material can be cut off. Furthermore, there is always a certain risk of accidents for the person leading the cutting edge.

  • the disadvantages described above may occur.
  • the first cutting edge of the cutting device according to the invention is designed to be automatically guided relative to the edge of the conveyor belt to be processed.
  • An automated guide means a mechanical arrangement which can take over and execute the handling of the first cutting edge instead of a manual handling of the first cutting edge.

  • This aspect of the present invention is based on the finding that during production the conveyor belt usually has to be moved from a vulcanization device to a take-up device or within the vulcanization device anyway. Accordingly, it can be very simple, e.g. in the direction of movement of the conveyor belt to be produced at the end of the vulcanization press or shortly after the
