A monitoring system checks for correct application of adhesive tracks 6 to e.g. the flap 2 df a cardboard blank 1 on a conveyor system. It includes sensors 14,15 for detecting the position of the blank 1 , and a central controller 18 for triggering a camera 16 to take one or more images of the blank 1 at suitable times after the blank 1 is detected, e.g. using the output of an encoder 17 . The images may be taken at the expected start, middle and end of the tracks 6 , and are analysed by the controller 8 to check for correct application of the tracks 6 . The controller 8 and sensors 14,15 can also be used to initially set the dimensions of the blank 1 , and the controller 8 can also track a failed blank 1 and reject it later in the conveyor system. |
