Abstract
A method of correcting the attitude of an article being conveyed in a feed system including two second feed paths for receiving the article from a first feed path and feeding the article so that a first part and a second part, which are related to each other, of the article will reach a target position for each of the first and second parts. The attitude of the article is corrected until the target positions are reached by compensating for a relative shift beyond a predetermined distance in a feeding direction between the first part and the second part of the article on the first feed path. The method comprises the steps of determining the extent of the relative shift by detecting times when the first part and the second part of the article pass respectively through a first measuring point and a second measuring point in the first feed path, and controlling respective speeds of feed by the second feed paths based on the detected extent of the relative shift for thereby causing each of the first part and the second part to reach the target position at a prescribed time.
