Rotary cutter for paper and printed products with a flat ring-shaped knife holder body ( 1 ) which rotatably receives a driven rotation shaft in its central opening ( 2 ) and an annular knife ring ( 3 ) is attached to the periphery, the radial and axial with a sharpened outer edge projects beyond the outer edge of the receiving body ( 1 ), characterized in that the knife receiving body ( 1 ) has devices for guiding and distributing cooling air in the receiving body ( 1 ) and for knife receiving ( 4 ). 2. Rotationsschneider gemäß Anspruch 1, dadurch gekennzeichnet, daß die Kontaktfläche zwischen Messer (3) und Aufnahmekörper (1) reduziert ist.2. Rotary cutter according to claim 1, characterized in that the contact area between the knife ( 3 ) and the receiving body ( 1 ) is reduced. 3. Rotationsschneider gemäß Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Kühlluft durch Verwirbelung und Erfassung der Umgebungsluft mit Hilfe von Einrichtungen am Messeraufnahmekörper (1) bereit gestellt wird.3. Rotary cutter according to claim 1 or 2, characterized in that the cooling air is provided by swirling and detection of the ambient air with the aid of devices on the knife holder body ( 1 ). 4. Rotationsschneider gemäß Anspruch 3, dadurch gekennzeichnet, daß die Einrichtungen zur Verwirbelung und Erfassung durch Nutvertiefungen (5) im Messeraufnahmekörpers (1) und zur Führung und Verteilung durch radial- oder spiralförmig verlaufende Kanäle zwischen Messerkranz (3) und Aufnahme (2) der Rotationswelle (6) gebildet werden.4. Rotary cutter according to claim 3, characterized in that the devices for swirling and detection by groove recesses ( 5 ) in the knife holder body ( 1 ) and for guiding and distribution through radial or spiral channels between the knife ring ( 3 ) and holder ( 2 ) Rotation shaft ( 6 ) are formed. 5. Rotationsschneider gemäß Anspruch 3, dadurch gekennzeichnet, daß die Einrichtungen zur Verwirbelung und Erfassung aus an der Oberfläche des Messeraufnahmekörpers (1) angeordneten schaufelartig vorwärts gekrümmten Flügeln gebildet sind, die axial über die Oberfläche des Messeraufnahmekörpers (1) überstehen, wobei der Überstand über die Außenoberfläche im Überdeckungsbereich von Ober- und Untermesser kleiner oder gleich dem Messerüberstand ist.5.
