Die Erfindung bezieht sich auf die weitere bildung eines pneumatisch betätigten Kreismesserhalters für Papierschneidemaschinen, bei welchem das in einem Führungsstück gehaltene, in Kugellagern laufende Kreismesser in seitlichen Ausnehmungen eines rahmenförmigen, nach dem Messer zu offenen Halters gleitet und zwischen dem Führungsstück an dessen oberer Schmalseite und dem Rahmen ein gefalteter Balg aus elastisch verformbarem Werkstoff für die Übertragung des pneumatischen Druckes angeordnet ist, nach Patent 1101128.The invention relates to the further formation of a pneumatically operated circular knife holder for paper cutting machines, in which the one held in a guide piece, in ball bearings running circular knives in side recesses of a frame-shaped, open to the knife Holder slides and a folded between the guide piece on its upper narrow side and the frame Bellows made of elastically deformable material arranged for the transmission of the pneumatic pressure is, according to patent 1101128.

Gemäß der Erfindung wird vorgeschlagen, bei einem derartigen Kreismesserhalter in der Gabelung des Messerhalters zwischen diesem und dem Messer je ein Kugellager anzuordnen, das unmittelbar über dem Kugellager des Messers sitzt. In weiterer Ausbildung des Erfindungsgedankens sind die Kugeln jedes Kugellagers in dichter Folge zwischen zwei zueinander konzentrischen Ringen auf jeder Seite des Messers eingesetzt. aoAccording to the invention, it is proposed that such a circular knife holder be in the fork of the knife holder to arrange a ball bearing between this and the knife, which is immediately above the ball bearing of the knife. The balls are a further development of the concept of the invention each ball bearing in close succession between two concentric rings on each side of the Knife used. ao

Diese Maßnahme hat den Vorteil, daß die Reibung zwischen Messer und Messerhalter auf ein Minimum herabgesetzt wird, so daß ein Festklemmen des Messers ausgeschlossen ist. Ferner wird durch die auf beiden Seiten angeordneten Kugeln bzw. Kugellagerringe eine exakte Führung des Messers in dem Halter gewährleistet, so daß ein Verkanten oder eine Schrägstellung des Messers, die bei der geforderten, sehr genauen Arbeitsweise derartiger Messer zu erheblichen Unzuträglichkeiten führen würde, mit Sicherheit vermieden wird.This measure has the advantage that the friction between knife and knife holder is reduced to a minimum is reduced, so that jamming of the knife is excluded. Furthermore, the on Balls or ball bearing rings arranged on both sides ensure exact guidance of the knife in the holder guaranteed, so that tilting or inclination of the knife, which is very precise when required Operation of such knives would lead to significant inconveniences, avoided with certainty will.

In der Zeichnung ist ein Ausführungsbeispiel gemäß der Erfindung veranschaulicht, und zwar zeigt Fig. 1 die Seitenansicht des Kreismesserhalters,In the drawing, an embodiment according to the invention is illustrated, namely shows 1 shows the side view of the circular knife holder,

Fig. 2 einen senkrechten Längsschnitt nach der Linie I-I der Fig. 1,Fig. 2 is a vertical longitudinal section along the line I-I of Fig. 1,

Fig. 3 eine Draufsicht auf den Messerhalter gemäß Fig. 1,Fig. 3 is a plan view of the knife holder according to Fig. 1,

Fig. 4 einen Querschnitt durch den Messerhalter nach der Linie II-II der Fig. 1.4 shows a cross section through the knife holder according to the line II-II of FIG. 1.

Der Messerhalter besteht aus dem Rahmen 1, der nach der Messerseite zu offen ist und in welchem der Messerhalter 2 mit dem darin gelagerten Messer gleitet. Zwischen dem oberen Teil des Messerhalters und dem Rahmen ist ein Balg 4 aus flexiblem Werkstoff eingesetzt, der über eine Rohrleitung 5 mit Druckluft gespeist wird. Das Messer selbst ist in einem Kugellager 6 gehalten, welches in dem vorteilhaft aus Kreismesserhaiter für Papierschneidemaschinen
Zusatz zum Patent: 1101128
The knife holder consists of the frame 1, which is too open on the knife side and in which the knife holder 2 slides with the knife stored therein. A bellows 4 made of flexible material is inserted between the upper part of the knife holder and the frame and is fed with compressed air via a pipe 5. The knife itself is held in a ball bearing 6, which is advantageously made of circular knife holder for paper cutting machines

Spritzguß hergestellten Messerhalter 2 eingespritzt ist. Zwischen dem Messerhalter und dem Rahmen sind Kugeln 8 vorgesehen, um die Reibung zu verhindern. Zur Verminderung der Reibung zwischen dem Messerhalter 2 und dem Messer 3 ist ein freier Raum beiderseits des Messers ausgespart, in dem je ein Kugellager 10 mit Kugeln 9 konzentrisch zu dem Kugellager 6 des Messers, befestigt ist. Das Kugellager 10 besteht aus konzentrisch zueinander angeordneten Ringen, welche die Kugeln 9 zwischen sich aufnehmen.Injection molded knife holder 2 is injected. Between the knife holder and the frame balls 8 are provided to prevent friction. To reduce friction between the knife holder 2 and the knife 3, a free space is cut out on both sides of the knife, in which each a ball bearing 10 with balls 9 concentric to the ball bearing 6 of the knife is attached. The ball bearing 10 consists of concentrically arranged rings, which the balls 9 between them take up.
