Abstract
An apparatus for connecting a first web of a web-shaped material unwinding from a first roll with the beginning of a second web of a web-shaped material unwinding from a second roll. The beginning of the second web is cemented to a transfer element by means of an adhesive area applied thereto. The transfer element is then moved toward the first web and/or the first web is moved toward the transfer element and the transfer element is accelerated to a speed corresponding to the speed of the expiring first web while a loose initial region of the second web is concurrently pulled tighter and the beginning of the second web is then cemented to the first web by means of another adhesive area applied to the beginning of the second web facing the side averse the first adhesive area and is pulled away from the transfer element. The acceleration of the second roll is carried out by the tension exerted by the first web after the beginning of the second web has been cemented to the expiring first web, and tension overloads and sudden loads exerted on the webs and the points of cementation between the web during initial acceleration being prevented by conducting the respective web over a force storage means which yields under increased tension on the path of the web to further processing stations.
