Abstract
The present invention provides a filling apparatus establishing positional coincidence between creases preformed in a packaging material and actual creases to thereby improve the appearance of a packaging container. A light source irradiates a portion of the outer circumferential surface of a packaging material tube which includes an overlap. A sensor receives light emitted from the light source and reflected from the outer circumferential surface of the tube. The overlap is detected as a peak in the sensor output. Light reflected from an edge portion of the packaging material exhibits greater intensity and is seen as a peak in the sensor output indicating position of the overlap.
