Abstract
An apparatus is disclosed for aligning at least two running webs with each other. It is characterized in that any lateral displacement is corrected at a position at a predetermined distance upstream of the displacement detection point or where excessive tension is not applied to the web to be corrected. Further, correction is made taking into consideration the time for the displacement detectors to follow the web movement and the time for the web to come back to a stable condition after splicing.
