Method and apparatus for sensing a seal on a film

A method and apparatus for detecting seals on a film from which bags are formed includes a force transmitter and a force sensor. The force transmitter transmits a force from the film to the sensor. The force sensor receives the transmitted force and provides a force signal. A controller receives the...

Zusammenfassung:	A method and apparatus for detecting seals on a film from which bags are formed includes a force transmitter and a force sensor. The force transmitter transmits a force from the film to the sensor. The force sensor receives the transmitted force and provides a force signal. A controller receives the force signal and provides a seal signal. The the force sensor may be an mechanical sensor, an acoustic sensor, a mechanical sensor, a vibration sensor or a piezoelectric sensor.
