Abstract
A method and apparatus are disclosed herein for detecting possibly defectively-sealed bags and for preventing said bags from being filled. A sensor is provided to develop a first signal upon detection of a defect in a line of adhesive on flexible bag-forming material moving past the sensor. The first signal is used to generate an output signal at a time corresponding to the time when the defect-containing portion of the bag-forming material has moved from the sensor into position to be filled with product. Preferably, said filling position is located a plurality of bag lengths downstream from said sensor.
