Abstract
A web position matching system for matching marks provided on a web of packaging material with a pitch corresponding to the length of one container, to a reference position comprises sensor device for detecting the displacement of the mark from the reference position, setting device for setting a usual amount of feed obtained by adding a predetermined amount of advance to a predetermined reference amount of feed corresponding to the length of one container when the displacement detected by the sensor device is smaller than a predetermined allowable displacement or setting a corrected amount of feed obtained by subtracting a predetermined amount of delay from the reference amount of feed when the detected displacement are not smaller than the allowable displacement, and device for correcting the usual amount of feed and the corrected amount of feed based on a pattern of frequencies with which the usual amount of feed and the corrected amount of feed are set by the setting device.
