Die Messerwelle 1 ist an ihrem stärkeren Ende genau wie das Messer 2 mit einer beliebigen Anzahl sternförmig angeordneter Schlitze 40 versehen, in welche die hakenförmig ausgestanzten Lappen 39 der mittels Schraube 3 befestigten Sicherungsplatte 4 eingreifen, um ein Loslösen des Messers von der Welle zu verhindern. Auf das dünnere, ebenfalls mit Gewinde versehene Ende der Welle 1 ist eine durch eine Stiftschraube 8 festgehaltene Kupplungshälfte 7, die gleichzeitig ein Herausschieben der Welle 1 nach vorn verhindert, aufgeschraubt, in welche das eine auf Kugeln laufende Ende einer mit einem Keil 10 versehenen und die lose Kupplungshälfte 22 tragenden Antriebswelle 9 gelagert ist, die durch einen Bund 41 in der Längsrichtung gesichert wird, während das entgegengesetzte Ende zur Befestigung der biegsamen Welle 38 ein Innengewinde hat. Der Bund 41 legt sich an eine Kugellagerung eines in den Körper 37 eingeschraubten Gewindestückes 14, welches einen Bund mit Aussparungen 42 hat, in welche der Kopf einer Schraube 13 greift, sobald das Gewindestück 14 in die richtige Lage gedreht ist.The knife shaft 1 is exactly like the knife 2 with any one at its stronger end Number of star-shaped slots 40 provided, in which the hook-shaped punched tabs 39 of the means Screw 3 fastened locking plate 4 engage to a loosening of the knife from the Prevent wave. On the thinner, also threaded end of the shaft 1 is a held by a stud 8 coupling half 7, which is a Prevents the shaft 1 from being pushed forward, screwed into which the one The end of a drive shaft 9 which is provided with a wedge 10 and carries the loose coupling half 22 and which runs on balls is mounted, which is secured by a collar 41 in the longitudinal direction, while the opposite End for securing the flexible shaft 38 has an internal thread. The federal government 41 subsides to a ball bearing of a threaded piece 14 screwed into the body 37, which has a collar with recesses 42 into which the head of a screw 13 engages as soon as the threaded piece 14 is rotated into the correct position.

Das Einrücken der losen Kupplungshälfte 22 wird durch einen in zwei Schraubenzapfen 15 pendelnden, mit in eine ringförmige Ausdrehung greifenden Nasen 43 versehenen Kupplungshebel 11 bewirkt, sobald ein Hebelmechanismus 23, 24, 25 und 26 durch Herunterdrücken eines Knopfes 27 in Bewegung gesetzt wird und sich um einen Bolzen 28 und eineThe engagement of the loose coupling half 22 is achieved by a screw pin 15 in two oscillating clutch lever provided with lugs 43 engaging in an annular recess 11 causes as soon as a lever mechanism 23, 24, 25 and 26 is set in motion by pressing down a button 27 and around a bolt 28 and a

Schraube 36 dreht, wobei der Stift 23 gegen den Hebel 11 drückt und eine Druckfeder 12 zusammenpreßt.The screw 36 rotates, the pin 23 pressing against the lever 11 and a compression spring 12 compresses. Beim Loslassen des Knopfes 27 wird infolge Ausdehnung der Feder 12 der Hebelmechanismus in seine ursprüngliche Lage gebracht und die Kupplungshälfte 22 durch die Nasen 43 des Hebels 11 ausgelöst.When the button 27 is released, the lever mechanism becomes due to the expansion of the spring 12 brought into its original position and the coupling half 22 through the lugs 43 of lever 11 triggered. Im unteren Teil des Körpers 37 befindet sich ein in seiner Längsrichtung verschiebbares Lager 31, welches einerseits ein Kugellager aufweist und anderseits mit einem zwei Augen 44 tragenden Reguliergewindestopfen 21 versehen ist.In the lower part of the body 37 there is a displaceable in its longitudinal direction Bearing 31, which on the one hand has a ball bearing and on the other hand with a two Eyes 44 carrying regulating screw plug 21 is provided. Das Lager 31 dient zur Aufnahme der zweiten Messerscheibe 18. Mittels eines durch die Augen 44 gesteckten Bolzens 33, welcher unter der Wirkung zweier Druckfedern 34 steht, wird das Lager 31 so beeinflußt, daß die Schneidkanten der Messer 2 und 18 gegeneinander gepreßt werden, wodurch ein genaues Einstellen der Messer nicht erforderlich ist. Um ein Drehen des Lagers 31 zu verhüten, befinden sich im Körper 37 vier Ansätze 45, zwischen welchen der durch eine Eindrehung 46 gegen Verschieben gesicherte Bolzen 33 zu beiden Seiten des Lagers 31 geführt ist. Die einerseits in dem Reguliergewindestopfen 21 mit Körnerspitze gelagerte, am anderen Ende mit Gewinde versehene Messerwelle 17 ist am Gewindeende samt dem Messer 18 mit sternförmig angeordneten Schlitzen genau wie die Welle 1 und das Messer 2 zum gleichen Zweck versehen und darauf die Sicherungsplatte 19 mittels der Schraube 20 befestigt. Außerdem sind das Messer 2 und die Platte 24 durch ein Schutzblech 32, das Messer 18 durch einen Schutzschieber 30, das Lager 31 mit dem Bolzen 33 durch einen Schieber 35 und die Öffnung über dem Hebel 11 durch einen Schieber 16 vollständig abgeschlossen, so daß eine gefahrlose und bequeme Handhabung der Vorrichtung möglich ist.The bearing 31 is used to hold the second cutter disk 18 by means of a through the eyes 44 of inserted bolt 33, which under the action of two compression springs 34 stands, the bearing 31 is influenced so that the cutting edges of the knives 2 and 18 against each other be pressed, whereby an accurate adjustment of the knife is not required. To prevent the bearing 31 from rotating, there are four lugs 45 in the body 37, between which the secured against displacement by a recess 46 Bolt 33 is guided on both sides of the bearing 31. The one in the regulating screw plug 21 mounted with a center punch, threaded at the other end Knife shaft 17 is at the end of the thread together with the knife 18 with slots arranged in a star shape just like the shaft 1 and the knife 2 provided for the same purpose and on it the locking plate 19 fastened by means of the screw 20.
