To move the knife roller in the axial direction, an electric motor is provided, the damage to the knife edges of which the knife with drive shaft 22 carries a pulley 24, over other knife edges of the knife roller in engagement which a drive belt 26 runs, which can be brought over.

As FIG. 3 shows, the switching valve 34 is with The object of the present invention is to 45 two solenoids 36, 38 and two hydraulic laths, the operating time of a cutting machine with lines 40, 42 provided, the direction of flow Knife roller and elastic counter roller to hydraugern the hydraulic medium through this and in addition the wear of the elastic overlapping lines 40, 42 by actuation of a delay on the counter roller during operation of the machine sliding valve pin 35 by means of the solenoids considerably reduce. The solution to this problem 50 36, 38 is reversible.

In a further development of the invention, the longitudinal displacement 40, 42 is via the switching valve 34 with the hydraulic displacement the counter-roll is made up of a double return line 50 and the sump 52, hydraulically operated cylinder piston collars, which in turn feeds the hydraulic medium unit existing device with the end of the 65 via the pump inlet line 54 of the pump 30 to counter-roller tied together. It can also lead to the reversal.

Die Umkehrung der Bewegung des Kolbens 46 und damit die Verschiebung der Walze 16 wird durch eine am entgegengesetzten Ende der Kolbenstange 48 angeordnete Anschlagplatte 56 und durch zwei Schalter 60, 62 erzielt, die auf einer Halteplatte 58 befestigt sind. Die Halteplatte 58 ist ihrerseits am äußeren Ende des doppeltwirkenden hydraulischen Zylinders 44 angeordnet.Roller 16 connected so that the longitudinal movement of the piston 46 is transmitted directly to the same. The reversal of the movement of the piston 46 and thus the displacement of the roller 16 is through a at the opposite end of the piston rod 48 arranged stop plate 56 and by two switches 60, 62 achieved, which are fastened on a holding plate 58. The holding plate 58 is in turn on the outside Arranged at the end of the double-acting hydraulic cylinder 44.
Die Schalter 60, 62 liegen zwecks Betätigung durch die Anschlagplatte 56 im Abstand voneinander, um die Grenzen der Bewegung der Platte und damit die Amplitude der Verschiebung durch die elektrischen Verbindungen der Schalter 62 und 60 bzw. der Solenoide 36 und 38 des Umschaltventils 34 zu bestimmen. The switches 60, 62 are for the purpose of actuation by the stop plate 56 at a distance from one another the limits of the movement of the plate and therefore the amplitude of the displacement due to the electrical To determine connections of the switches 62 and 60 or the solenoids 36 and 38 of the switching valve 34.
Im Betrieb erfolgt die Längsverschiebung der Walze 16 gleichzeitig mit dem Durchgang des blattförmigen Materials zwischen den Walzen 14 und 16. Die durch die Schalter 60 und 62 bestimmte Amplitude der Verschiebung beträgt beispielsweise bei jeder Umdrehung der Walze 16 1,8 mm, so daß das Schneidmesser 15 nicht ständig gegen eine Breite des elastischen Überzuges anliegt, welche der Breite des Schneidmessers entspricht, sondern die Abnützung des elastischen Überzuges über die ganze Amplitude der Längsverschiebung verteilt wird.In operation, the longitudinal displacement of the roller 16 takes place simultaneously with the passage of the sheet-shaped Material between rollers 14 and 16. The amplitude determined by switches 60 and 62 the displacement is, for example, 1.8 mm for each revolution of the roller 16, so that the Cutting knife 15 does not constantly bear against a width of the elastic coating which is the width of the Corresponding to the cutting knife, but the wear and tear of the elastic coating over the entire amplitude the longitudinal displacement is distributed.
