- Taperolle 25, 26 follows the separating cut at an exact distance to the researchlagegen tape 22.
- Between the two web rolls 23, 24 is an approximately triangular guide body 29, the webs 13, 15 each in the area of the system to the web rolls 23, 24 leads.
- the track rollers 23, 24 and the Taperollen 25, 26 are rotatably mounted with axle journals or drive shafts in support walls 30, 31 of a support frame ( Fig. 9 ).
- the Taperolle 25, 26 is driven by a motor 32 which acts via a shaft 33 with coupling 34 on the Taperolle 25, 26.
- the relative, axially parallel adjustment of the web rolls 23, 24 to each other is effected by an eccentric gear.
- the web roll 24 is mounted on an eccentric shaft 35, which extends offset to a drive shaft 36.
- the eccentric shaft 35 is rotatable by a separate gear, by a mounted on the eccentric shaft 35 pivot arm 37 which is connected to a (pressure medium) cylinder 38 and with its piston rod.
- the web roll 24 is moved transversely to reduce or increase the distance from the other web roll 23.
- To the splice unit 19 further includes cutting members for positionally accurate severing of the respective new web 15 before the beginning of the change process. It is in each case a transversely to Neubahn 15 movable, roller or disc-shaped knife 39. This is attached to a bracket 40 on the table top 20. The knife 39 is seated on a carriage 41, which is movable by hand across the new web 15 or across the table top 20. The carriage 41 is slidably mounted on a guide rod 42 for this purpose. The rotating blade 39 works when performing the separating cut with a right edge or horizontal rail 43 on the table top 20, ie below the new rail 15, together. The alignment rail 43, together with the knife 39, ensures an exact, precise separation cut of the new web 15, in particular at the marked or defined position.
- a pivot bearing 48 of the arm 47 is associated with a sensor 49 which detects the exact angular position of the pivot bearing 48 and thus of the arm 47. From the position of the pivot bearing 48 results in the memory length of the process path 13.

- the bobbins 14, 16 and the support pins 10, 11 are each driven by three-phase motors 50, 51. These can be quickly raised to the required rotational speed, but also serve as an engine brake.
- the web rolls 23, 24 and the Taperollen 25, 26, however, are driven by stepper motors, so a simpler design of a servomotor. The stepper motors ensure precise movement steps.
- the procedure described is as follows: In time before the start of the change of course, the new line 15 is prepared (manually). For this purpose, a deducted from the Neubobine 16 initial piece 52 of the new rail 15 is brought into an exact position, which is made Fig. 5 results. The new web 15 or the starting piece 52 extends into the region of the smallest distance of the web rolls 23, 24 from each other and slightly beyond. This exact length of the initial piece 52 is created in forming a leading edge of the new web 15 by means of the knife 39. In this case, the separating cut is carried out at a predetermined position, namely with reference to a printed mark applied to the web or design printing of the new web 15.
- the initial piece 52 created by the separating cut of the knife 39 is determined by a mechanical measuring device.
- a web loop 53 is drawn between the two guide rollers 17, 18, with a movable intermediate roller 54 which is moved transversely between the guide rollers 17, 18, taking along a certain length of the new rail 15 (FIG. Fig. 3 , right).
- the intermediate roller 54 is attached to an actuating arm 55, which consists of a in Fig. 3 shown on the left in the in Fig. 3 right shown working position is moved.
- a monitoring element namely an initiator 56. This ensures that the web change operation is initiated only after the formation of the web loop 53.
- the separation cut by means of knife 39 to create an exact leading edge of the new rail 15.
- the tape 22 is placed on the runway 13 associated Taperolle 25, in the region of the silicone coating 27 (FIG. Fig. 5 ). If the runway 13 continues to run unchanged, the tape 22 is transferred to the runway 13 ( Fig. 6 ). For this purpose, it is necessary to accelerate the Taperolle 25 during a partial rotation to the speed of the professionbahn 13. This is achieved in such a way that the taper roller 25 is first rotated in the opposite direction ( Fig. 5 ) and then after this "Ausholyak" when reversing the direction of rotation on the speed of the new rail 15 is accelerated until the transfer of the tape 22 (FIG. Fig. 6 ).
- the web roller 24 holding the starting piece 52 of the new web 15 is adjusted by actuating the cylinder 38 to a small distance from the opposite web roll 23 (FIG. Fig. 6 ). Furthermore, the web roll 24 is also driven in rotation. If the tape 22 reaches the area of the smallest distance between the two web rolls 23, 24, there is an adhesive connection with the starting piece 52. The following new sheet 15 is now pulled along by the runway. At the same time as a result of continued rotational movement of the taper roller 25 belonging to this separating knife 28 has become effective and has the runway 13 at the top of the web roll 23 severed ( Fig. 7, Fig. 8 ) with the formation of the remainder piece 21. The (new) run-off track 13 is conveyed at the same speed, whereby a precisely defined blank in the area of the tape connection is later separated out.

Weiterhin gehört zur Splice-Einheit 19 ein in Förderrichtung auf die Bahnwalzen 23, 24 folgender Bahnspeicher 44. Dieser bildet mit Hilfe von ortsfesten Umlenkrollen 45 und mit diesen zusammenwirkenden weiteren Umlenkrollen 46 an einem Arm 47 mehrere Bahnschleifen, die durch Schwenkbewegung des Arms 47 vergrößert oder verkleinert werden können. Einem Drehlager 48 des Arms 47 ist ein Sensor 49 zugeordnet, der die exakte Winkelstellung des Drehlagers 48 und damit des Arms 47 erkennt. Aus der Stellung des Drehlagers 48 ergibt sich die Speicherlänge der Ablaufbahn 13. Der Sensor 49 steuert den Antrieb der Bobinen 14, 16 bzw. der Tragzapfen 10, 11.Furthermore, one of the
Eine Besonderheit sind die ausgewählten Antriebe nach Maßgabe der Funktion und Wirtschaftlichkeit. Die Bobinen 14, 16 bzw. die Tragzapfen 10, 11 werden jeweils durch Drehstrommotoren 50, 51 angetrieben. Diese können kurzfristig auf die erforderliche Drehgeschwindigkeit hochgefahren werden, dienen aber auch als Motorbremse. Die Bahnwalzen 23, 24 sowie die Taperollen 25, 26 werden hingegen durch Schrittmotoren angetrieben, also einer einfacheren Ausführung eines Servomotors. Die Schrittmotoren gewährleisten jeweils exakte Bewegungsschritte.A special feature are the selected drives in accordance with the function and efficiency. The
Bei einem Bahn- bzw. Bobinenwechsel wird mit der beschriebenen Vorrichtung wie folgt vorgegangen: Rechtzeitig vor Beginn des Bahnwechsels wird die Neubahn 15 (manuell) vorbereitet.
