Definitions

  • the disclosure relates to a spreading unit for spreading viscous material, a system for spreading viscous material, and a method for spreading a viscous material.
  • sealing material such as, for instance, aircraft sealing compounds or silicone-like sealing material
  • various application units are known.
  • a shaping nozzle for applying and shaping a seal weld on a component is described. With a nozzle, respectively only one weld with a nozzle-specific shape can in this case be formed.
  • This spreading unit has two brush portions, which, for the bridging of offsets in a component, can be manually adjusted relative to one another. Two portions of different height can herewith be surface-treated across a projection. For the adjustment, the spreading process has to be interrupted. In addition, a continuous adaptation of the spreading unit to varying component surfaces is not possible.
  • the disclosure is based on the problem of designing and refining a known spreading unit such that viscous material can be spread in a simple and flexible manner on a component.
  • an adjustable shape or contour can overall be provided in order to meet altered requirements concerning the length of a material application.
  • the start and/or end of an applied web of a sealing material for example, can be shaped in a controlled manner.
  • a clean and repeatable shape at the start and end of the web is hence able to be achieved.
  • Right at the end of the web given an invariable shape of the shaper, a stringing of a sealing material, and/or undercuts, frequently materialize following a reduction of the material flow.
  • a shaping contour here generally comprises a purposefully shaped boundary, which comes partially or fully into contact with the applied material and effects a reshaping or a shape-forming spreading of the material.

  • the spreading unit can have a sensor, such as a line laser, for detecting that region of the component that is to be coated.
