  • the protection means 30 may also be made of a different material suitable for enabling cost-effective manufacture, minimizing noise and / or minimizing friction between the guard and the batten.
  • the device is particularly useful in a plant for tire manufacturing or tire processing.
  • the material web is then a rubber web.
  • the speed of the web eg in the range of 50 m / min
  • the speed of the web is typically less than the speed of the web in a textile manufacturing line (eg in the range of 200 m / min).
  • the device should be adapted accordingly.
  • ball-bearing rollers may be used in the device.
  • a corresponding coating of the slats may be provided, for example, a non-stick coating.
  • the device can also be operated continuously, that is, the lateral displacement control is performed while the roller is rotating. This is the case, for example, when the device is used in the area of the rewinder, the extruder, and / or the calender in the tire manufacturing plant.
  • the device may also be operated discontinuously, that is, the lateral displacement control is performed at stop intervals in which the roller does not rotate. This is the case, for example, when the device is used in the region of the cutting device in the tire manufacturing plant, wherein during the stop intervals the material web is cut by the cutting device.
  • the device can also be used in other applications, such as in a textile manufacturing or textile processing plant, the web then being a textile web.
  • the apparatus may also be used in a papermaking or papermaking plant, the web then being a paper web, or in a plant for plastic film production or plastic film processing, the web then being a plastic web.
  • the device may include a detection means (not shown) for detecting the position of the web of material.
  • the apparatus may include control means (not shown) for controlling lateral displacement.
  • the control device is then connected to the detection means and the actuator such that the control device evaluates signals of the detection means and controls the actuator accordingly to regulate the lateral displacement of the material web.
  • the detection means may be a web edge sensor which detects the edge of the material web by means of a light barrier, and / or a camera. However, other types of detection means may be provided.
