schwindigkeit in die Warenbahn 5 ein und trennt diese mit einem Schnitt senkrecht zur Warenbahn durch. Bei dem Querschnitt wird gleichzeitig der neue Anfang der Warenbahn 5 durch die Andruckwalze 11 an die mit Klebstoff viorpräparierte leere Hülse 1 angedrückt. Die s hinter dem Messer 10 mitrotierende Bürste 14 und die bei dem Querschnitt aus dem Blasrohr 13 austretende Luft unterstützen das Anlegen des neuen Anfangs der Warenbahn 5 an die leere Hülse 1.speed into the web 5 and separates it with a cut perpendicular to the web. at the cross-section is at the same time the new beginning of the web 5 by the pressure roller 11 to the with Empty sleeve 1 previously prepared with adhesive pressed on. This behind the knife 10 co-rotating brush 14 and the one emerging from the blowpipe 13 in the cross section Air support the application of the new beginning of the material web 5 to the empty tube 1.

The helical arrangement of the knives | teeth in the second embodiment is shown schematically in Fig.4 ifl As from Fig. 3 can be seen, is ■ * ■ :; the knife shaft 9. the brush 14 and the blowpipe 13; supporting pivot lever 8 in a pivot arm 15 ge-L ;. stored, which also carries two Umlenkrollcn 16 and is || during winding in the dashed line position indicated ψ- stands During winding, the web 5 of the ψ: empty tube 1, as shown in phantom, immediate U bar led to the winding roll 2 the empty tube 1. Il knife shaft 9 and the drum 7 Airch's own fei drives or a common main drive are driven synchronously with the web speed.
Zur Vorbereitung des Schnitts wird der Schwenkarm IS in die Warenbahn S und in die dargestellte Stellung geschwenkt in der die Warenbahn um mehr als den halben Umfang um die leere Hülse 1 und über die Umlenkrollen 16 zur Wickelrolle 2 geführt wird. Der Schwenkhebel 8 mit der Messerwelle 9 bleibt hierbei zunächst in der strichpunktiert angedeuteten Stellung. Zur Durchführung des Schnitts wird darauf der Schwenkhebel 8 mit der Messerwelle 9 pneumatisch gegen die Warenbahn 5 geschwenkt Das spiralförmig angeordnete Messer 10 trennt die Warenbahn 5, wie in F i g. 4 angedeutet ist mit einer schrägen Schnittlinie 17 durch. Der Zipfel des neuen Bahnanfangs wird mittels der Bürste 14 mit Unterstützung durch die aus dem Blasrohr 13 austretenden Luft an die leere Hülse 1 angestrichen, so daß er mit der leeren Hülse mitläuft, zwischen diese und die Trommel 7 geführt und um die leere Hülse herumgewickelt wird.To prepare for the cut, the swivel arm IS is placed in the material web S and in the position shown pivoted in the the web by more than half the circumference around the empty tube 1 and over the pulleys 16 is guided to the winding roll 2. The pivot lever 8 with the knife shaft 9 remains here initially in the position indicated by dash-dotted lines. To carry out the cut, the Pivoting lever 8 with the knife shaft 9 pivoted pneumatically against the web 5 The spiral arranged knife 10 separates the web 5, as in F i g. 4 is indicated with an inclined cutting line 17 by. The tip of the new beginning of the web is by means of the brush 14 with the support of the from the Blowpipe 13 escaping air to the empty sleeve 1 painted so that it runs with the empty sleeve, between this and the drum 7 is guided and wrapped around the empty tube.
