Abstract
The invention relates to a method for checking an aerosol-generating article with a ventilation zone for manufacturing defects. comprising: -providing an aerosol-generating article with a ventilation zone, the ventilation zone comprising a plurality of perforations, -cutting the aerosol-generating article along a plane through the plurality of perforations, thereby creating an intersection through the plurality of perforations, and -checking the intersection for manufacturing defects. Such a method for checking an aerosol-generating article for manufacturing defects can also check for the shape and the positioning of the perforations inside the article.
Claims20
A method for checking an aerosol-generating article with a ventilation zone for manufacturing defects, comprising:
- providing an aerosol-generating article with a ventilation zone, the ventilation zone comprising a plurality of perforations,
- cutting the aerosol-generating article along a plane through the plurality of perforations, thereby creating an intersection through the plurality of perforations, and
- checking the intersection for manufacturing defects, wherein a reference image of a cross-sectional cut of a perforation is provided and wherein the reference image is superimposed on a cross-sectional cut of a perforation in the intersection of the aerosol-generating article in order to visually check for manufacturing defects.
Inspection tool for checking for manufacturing defects in a ventilation zone of an aerosol-generating article, the ventilation zone comprising a plurality of perforations, the inspection tool comprising:
- a cavity for receiving the aerosol-generating article, wherein the aerosol-generating article is cut along a plane through the ventilation zone for creating an intersection through the plurality of perforations,
- a reference image of a cross-sectional cut of a perforation, and
- means to rotate the reference image and the cut-aerosol-generating article relative to each other for superimposing the reference image on a cross-sectional cut of a perforation within the intersection.
