| titleOfInvention | Method and apparatus for detecting holes in substrates in absorbent article converting lines |
| abstract | The methods herein utilize polarized light for detecting through holes in substrates. A light source directs light through a first polarization filter having a first polarization axis, wherein polarized light travels from the first polarization filter and toward a substrate. The orientation of the polarized light is changed while traveling through substrate material, and is scattered. However, polarized light traveling through a hole in the substrate remains unscattered. A second polarization filter receives unscattered light and scattered light traveling away from the substrate. The second polarization filter includes a second polarization axis angularly offset from and not parallel with the first polarization axis. As such, the second polarization filter blocks the advancement of unscattered light while the scattered light is not blocked by the second polarization filter. The hole is detected based on an absence of unscattered light surrounded by light traveling from the second polarization filter. |
