ABSTRACT:
According to the invention, there is provided a bag making machine including feeding means for feeding two or more superposed layers of plastic film longitudinally thereof and intermittently for a length, the layers of plastic film having void area means such as notch hole means, and a cutter for cutting the layers of plastic film crossly thereof along a line predetermined with respect to the void area means whenever feeding the layers of plastic film are temporarily stopped, to thereby successively make plastic bags. A detector is disposed near the cutter for recognizing the contour of the void area means as an image data immediately before or when the layers of plastic film are temporarily stopped. A computer is connected to the detector for calculating the difference between the position of the predetermined line of the layers and the position of the cutting edge means of the cutter in accordance with the image data of the detector. Drive means is connected to the computer for moving the cutter parallel to the layers feeding direction in response to the output signal from the computer to thereby compensate and eliminate the difference between the position of the predetermined line of the layers and the position of the cutting edge means of the cutter.
