 ten, wobei zur axialen Fixierung eine auf die Achse --8-- aufschraubbare Mutter --11-- dient, die mit einem   Hebel --l2-- angezogen   werden kann, um die   Achse --8-- zwischen   der Mutter - und einer drehfest mit ihr verbundenen Anschlagplatte --13-- am andern Achsenende im Lagerbock --10-- festzuspannen. Auf der Achse --8-- sitzt zwischen den Schenkeln des Lager-   bockes --10-- eine Lagerhülse --14--,   die mit dem Schwenkarm --6-- und dem Schwenkhebel - fest verbunden ist.

   Da die Länge der   Lagerhülse --14-- auf   den Abstand der beiden Schenkel des Lagerbockes --10-- voneinander abgestimmt ist und ein Auseinanderbiegen der Schenkel durch ihre Einspannung zwischen der Anschlagplatte --13-- und der Mutter --11-- verhindert wird, ergibt sich eine spielfreie Lagerung für den   Werkzeugträger --4-- in   Richtung der Drehachse - der Messerscheibe was Voraussetzung für ein genaues Nachschleifen der Messer--3-ist. Die Einspannung mit Hilfe der   Mutter --11-- bietet   darüber hinaus die Möglichkeit, den Schwenkwiderstand einzustellen. 



   Das Schleifwerkzeug --5--, das als Schleifscheibe ausgebildet ist, ist im Werkzeugträger - mit Hilfe einer Spindel --15-- über ein   Handrad --16-- an   die   Messer --3-- anstellbar   gelagert, wobei die gewählte Anstellung durch eine Gegenmutter --17-- mit einem Hebel --18-festgestellt werden kann. 



   Nach der Anstellung des   Schleifwerkzeuges --5-- an   die Messer --3-- der Messerscheibe - kann das Schleifwerkzeug --5-- durch ein Verschwenken des Schwenkhebels --9-- über die Schneidenlänge der am Schleifwerkzeug vorbeibewegten   Messer --3-- geführt   werden, wobei die Messer entsprechend geschliffen werden. Nach dem Schleifvorgang kann das Schleifwerkzeug - durch eine gegensinnige Verstellung der Spindel --15-- wieder freigestellt werden.

 ten, with a --11-- nut that can be screwed onto the axis --8--, which can be tightened with a lever --l2--, around the axis --8-- between the nut - and a non-rotatably connected stop plate --13-- at the other end of the axis in the bearing block --10--. On the axis --8-- sits between the legs of the pedestal --10-- a bearing sleeve --14--, which is firmly connected to the swivel arm --6-- and the swivel lever.

   Since the length of the bearing sleeve --14-- is matched to the distance between the two legs of the pedestal --10-- from each other and the legs are bent apart by their clamping between the stop plate --13-- and the nut --11-- is prevented, there is play-free storage for the tool holder --4-- in the direction of the axis of rotation - the knife disc, which is a prerequisite for exact regrinding of the knives - 3-. Clamping with the help of the nut --11-- also offers the option of adjusting the swivel resistance.



   The grinding tool --5--, which is designed as a grinding wheel, is mounted in the tool carrier - with the help of a spindle --15-- via a handwheel --16-- to the knives --3--, whereby the selected position can be locked by a lock nut --17-- with a lever --18-.



   After adjusting the grinding tool --5-- to the knives --3-- of the knife disc - the grinding tool --5-- can be pivoted by swiveling the swivel lever --9-- over the cutting length of the knives --3 moving past the grinding tool - Be guided, whereby the knives are ground accordingly. After the grinding process, the grinding tool can be released again by adjusting the spindle in opposite directions.
