Definitions

  • a very fine perforation is particularly subjected to those film-like materials that are so dense due to their material structure that they have little or no breathability. This is especially the case with plastic films, synthetic leather, coated textiles or the like.
  • plastic films, synthetic leather, coated textiles or the like For a wide variety of uses, e.g. B. in the clothing sector, such materials require a certain level of water vapor permeability, while at the same time a high level of waterproofness is required.
  • the water vapor permeability is essentially from depending on the number of perforations per unit area and their absolute size. The watertightness is determined by the size of the two three largest holes per 100 cm of material. In order to meet the very high standards in this regard, a uniform and dense perforation with the smallest perforation hole diameter must be achieved.
  • FIG. 1 shows the mechanical part of the arrangement.
  • the embodiment shown is designed for vertical guidance of the material web 1 to be perforated.
  • the vertical arrangement prevents contact with one of the electrodes, so that surface damage to sensitive material web coatings based thereon is avoided.
  • the two electrodes consist of multi-row needle fields 3 and 4 which extend over the width of the material web.
  • FIG. 3 shows the needle field 3 in a rear view.
