摘要： A process 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 being cemented to the unwinding first web by attachment of the beginning of the second web to a transfer element and then effecting a relative movement between the transfer element and the first web. More specifically, a cementing occurs of the beginning of the second web to the transfer element by means of an adhesive area applied thereto. Thereafter, this area is accelerated to a lineal speed corresponding to the lineal speed of withdrawal of the expiring first web and in the same direction so that the loose initial region of the second web is simultaneously pulled tighter. The beginning of the second web is cemented to the first web by another adhesive area applied to the beginning of the second web on the side opposite the first mentioned adhesive area. The beginning of the second web is pulled away from the transfer element and thereafter the expiring first web is cut behind the point of cementation with the beginning portion of the second web. The second roll is accelerated by the tension exerted by the first web after the beginning of the second web has been cemented to the expiring first web. A yielding occurs to tension overloads and sudden loads exerted on the webs and the points of cementation between the web during initial acceleration by reason of the fact that the web is conducted over a forced storage means which yields under increased tension on the path of the web to further processing stations.
