Bei der Ausführungsform gemäß Fig. 13 ist gegenüber den vorbeschriebenen Ausführungsformen im wesentlichen unterschiedlich, daß hier ein zusätzlicher Verbindungsstreifen 6 zwischen die Bahnenränder 21 und 22 eingebracht wird. Dieser Verbindungsstreifen 6 wird an beiden Seiten mit einem Aktivierungsmittel 61 versehen, das aus zwei Behältern 611 in definierter Menge über Düsen 6111 aufgetragen wird. Erst durch die Einwirkung des Aktivierungsmittels 61 auf die Flächen des Verbindungsstreifen 6 werden diese klebrig, so daß eine vorteilhaftere Verarbeitung gegeben ist als es bei der Verwendung von Verbindungsstreifen der Fall wäre, die von vornherein beidseitig klebend ausgebildet sind. Erforderlichenfalls kann auch hier zwischen den Düsen 6111 und den Rollen 18 zur Beschleunigung der Trocknung ein Warmlüfter wie bei der Ausführungsform nach F i g. 11 vorgesehenIn the embodiment according to FIG. 13, compared to the above-described embodiments in essentially different that here an additional connecting strip 6 between the web edges 21 and 22 is introduced. This connecting strip 6 is activated on both sides with an activating means 61 provided, which is applied from two containers 611 in a defined amount via nozzles 6111. Only by the action of the activating agent 61 on the surfaces of the connecting strip 6, these become sticky, so that processing is more advantageous than when using connecting strips would be the case, which are designed to be adhesive on both sides from the outset. If necessary can also be used here between the nozzles 6111 and the rollers 18 to accelerate the drying a warm fan as in the embodiment according to FIG. 11 provided
