  • Method and apparatus for ply discontinuity detection
    Patent number: 5737238
    Abstract: A ply break detector for a laminate web uses a short time constant low pass filter and a long time constant low pass filter for filtering output signals from a sonic web scanner. A difference circuit compares output signals from the two filters to create a difference signal. A ply discontinuity indication is generated when the difference signal exceeds a predetermined threshhold with a predetermined persistence. Analog and digital versions are disclosed.
