Dafür wird das  In order to have sufficient time for the removal of a finished portion of food, especially at very high cutting performance, the cutting knife preferably performs one or more idle cuts, d. H. It rotates at a constant speed, but does not cut any slices off the food bar. That will be for that
Schneidmesser erfindungsgemäß von der Schneidebene und/oder von dem vorderen Ende des Lebensmittelriegels 2 wegbewegt, wobei der Vorschub des Lebensmittelriegels dann zumindest unterbrochen wird. Gegebenenfalls wird der Lebensmittelriegel sogar Cutting knife according to the invention moved away from the cutting plane and / or from the front end of the food bar 2, wherein the feed of the food bar is then at least interrupted. If necessary, the food bar even becomes
zurückgezogen. Sobald die jeweilige Lebensmittelportion aus der Fallkurve der withdrawn. As soon as the respective food portion from the falling curve of the
Lebensmittelscheiben wegtransportiert worden ist, wird das Messer wieder zurück in die Schneidebene bewegt und eine neue Portion kann aufgeschnitten werden. Food wafers has been transported away, the knife is moved back into the cutting plane and a new portion can be cut open.

In dem vorliegenden Fall wird das Schneidmesser so lange gegen den Uhrzeigersinn gedreht, bis eine Verdrehsicherung 22, die in dem vorliegenden Fall verschieblich, vorzugsweise parallel zu der Rotationsachse des Schneidmessers und federnd gelagert ist und die von dem Schneidmesser in die Anlagefläche 23 gedrückt worden ist, wieder in die Sicherungsausnehmung 17 zurückspringt und somit eine Verdrehung des Schneidmessers im Uhrzeigersinn verhindert. Durch das Sicherungsmittel 17 wird sichergestellt, dass sich das Schneidmesser nicht von der Anlagefläche 23 lösen kann. Im Falle eines Versagens des Befestigungsmittels (nicht dargestellt), verhindert das Sicherungsmittel, dass sich das Schneidmesser von der Messeraufnahme löst und somit einen Sach- und/oder Locking recess 17 has been placed on the securing means 21 and the cutting blade rests against the contact surface 23, it is rotated counterclockwise, so that the securing recess 17 is no longer congruent with the fastening means 21. In the present case, the cutting blade is rotated counterclockwise until an anti-rotation 22, which is displaceable in the present case, preferably parallel to the axis of rotation of the cutting blade and resiliently and has been pressed by the cutting blade in the contact surface 23, springs back into the securing recess 17 and thus prevents rotation of the cutting blade in a clockwise direction. By the securing means 17 ensures that the cutting blade can not be detached from the contact surface 23. In the event of failure of the fastener (not shown), the securing means prevents the cutting blade from detaching from the blade holder and thus a material and / or
Personenschaden verursacht. Die erfindungsgemäße Aufschneidevorrichtung kann im Versagensfall kontrolliert abgeschaltet werden. Dann wird die Verdrehsicherung manuell in Richtung der Anlagefläche gedrückt, bis das Schneidmesser im Uhrzeigersinn soweit gedreht werden kann, dass die Sicherungsausnehmung 17 und das Sicherungsmittel 21 deckungsgleich sind. Danach kann das Schneidmesser entlang der Rotationsachse des Schneidmessers von der Messeraufnahme abgezogen werden. Personal injury caused.
