Abstract

The cutter and/or perforator wheel is for paper, metal foils and/or synthetic films. It has an abutment disc (2) of preselected diameter and a similar press-on disc (4). A removable disc-shaped cutter and/or perforator blade (6) is coaxially clamped between the two. The cutting/perforation line (8) of the blade projects slightly over the circumference of the two discs. ADVANTAGE - No need to replace any parts, except for cutter blade.

Zum Schärfen des Schneid- und/oder Perforationsumfangs der Schneid- und/oder Perfor­ rationsblätter wird das Verfahren bevorzugt gemäß Anspruch 8 ergänzt.A process using the cutting and / or perforation blade can be rationally produced in large quantities nen is specified in claim 7. To sharpen the cutting and / or perforation circumference of the cutting and / or perforation ration sheets, the method is preferred according to claim 8 added.

Die Erfindung wird im folgenden an einem Ausführungsbei­ spiel unter Hinweis auf die beigefügten Zeichnungen be­ schrieben.The invention is illustrated below in one embodiment game with reference to the attached drawings wrote.

Fig. 1 zeigt ein Schneid- und/oder Perforationsrad in Explosionsdarstellung im Achsschnitt. Fig. 1 shows a cutting and / or perforation wheel in an exploded view in axial section.

Fig. 2 zeigt das zusammengesetzte Schneid- und/oder Perfo­ rationsrad nach Fig. 1 in Blickrichtung II der Fig. 1. Fig. 2 shows the assembled cutting and / or Perfo rationsrad of FIG. 1 in viewing direction II of FIG. 1st

Fig. 3 zeigt eine Ansicht des Schneid- und/oder Perfora­ tionsblatts der Ausführungsform nach den Fig. 1 und 2. Fig. 3 is a view of the cutting and / or perfora tion sheet shows the embodiment according to FIGS. 1 and 2.

Das Schneid- und/oder Perforationsrad nach dem Ausführungs­ beispiel weist eine Widerlagerscheibe 2 mit einem vorge­ gebenen Außendurchmesser auf und eine Andruckscheibe 4 mit im wesentlichen dem gleichen Außendurchmesser. Koaxial zwischen die Widerlagerscheibe 2 und die Andruckscheibe 4 ist austauschbar ein kreisscheibenförmiges Perforations­ blatt 6 gespannt, das mit seinem Perforationsumfang 8 rundum geringfügig über die Außendurchmesser der Wider­ lagerscheibe 2 und der Andruckscheibe 4 vorsteht. Die Widerlagerscheibe 2 weist eine Nabe 10 auf, die ein zentrales Loch 12 in dem Perforationsblatt 6 und ein zentrales Loch 14 in der Andruckscheibe 4 durchsetzt und mit einem Außen­ gewinde 16 zum Aufschrauben eines Andruckrings 18 versehen ist. In dem Andruckring 18 befinden sich Löcher 20, in die mit einem Drehwerkzeug eingegriffen werden kann. Der Umfang der Nabe 10 nächst der Widerlagerscheibe 2 ist als Führungs­ fläche 19 für das zentrale Loch 12 in dem Perforations­ blatt 6 ausgebildet. Die Nabe 10 weist in ihrem Umfang vier axiale Drehsicherungsausnehmungen 22 auf, die in die Widerlagerscheibe 2 durchsetzende Bohrungen 24 übergehen. Zwei dieser Drehsicherungsausnehmungen 22 wirken mit radial nach innen in das Loch 12 der Perforationsscheibe 6 ragenden Drehsicherungsvorsprüngen 26 zusammen. Die Perfora­ tionsscheibe 6 kann somit in zwei verschiedenen Winkelstel­ lungen auf die Nabe 10 gesteckt werden. Die Widerlagerschei­ be 2 und die Andruckscheibe 4 sind an ihrem Umfang durch mit ihren Basen einander zugewandten konischen Flächen 28, 30 begrenzt. In einem zentralen Loch 32 der Nabe 10 sitzt ein - nicht dargestelltes - auf eine Lagerachse zu steckendes Wälzlager.The cutting and / or perforation wheel according to the embodiment, for example, has an abutment plate 2 with a pre-given outer diameter and a pressure plate 4 with substantially the same outer diameter. Coaxially between the abutment wheel 2 and the pressure plate 4 is replaceable, a circular disk-shaped perforation sheet 6 is tensioned, the bearing plate 8 with its Perforationsumfang around slightly beyond the outer diameter of the abutment 2 and the pressure plate 4 protrudes. The abutment plate 2 has a hub 10 which passes through a central hole 12 in the perforation sheet 6 and a central hole 14 in the pressure plate 4 and is provided with an external thread 16 for screwing on a pressure ring 18 . There are holes 20 in the pressure ring 18 which can be engaged with a turning tool. The circumference of the hub 10 next to the abutment plate 2 is designed as a guide surface 19 for the central hole 12 in the perforation sheet 6 . The hub 10 has four axial rotation lock recesses 22 in its circumference, which merge into the abutment disk 2 through holes 24 . Two of these anti-rotation recesses 22 cooperate with anti-rotation projections 26 projecting radially inwards into the hole 12 of the perforated disk 6 . The perforation disc 6 can thus be inserted in two different angular positions on the hub 10 . The abutment plate 2 and the pressure plate 4 are limited on their circumference by their bases facing conical surfaces 28 , 30 . In a central hole 32 of the hub 10 sits a roller bearing (not shown) to be placed on a bearing axis.

Zur Herstellung des Perforationsblatts wird ein Stahl­ blatt - bevorzugt einer Stärke von 0,15 bis 0,25 mm - beidseitig mit einem Fotoresist beschichtet. Das Foto­ resist wird auf wenigstens einer Seite des Stahlblatts durch eine Schablone belichtet, die den Begrenzungen des Perforationsrads zugeordnete, aus Fig. 3 ersichtliche, linienförmige, lichtundurchlässige Bereiche aufweist. In den belichteten Bereichen wird das Fotoresist gehärtet. In den unbelichteten Bereichen wird das Fotoresist abge­ waschen. Dann wird das Stahlblatt in den unbelichteten Be­ reichen zur Bildung des Perforationsblatts durchgeätzt. Schließlich werden die belichteten Bereiche des Fotore­ sists von dem Perforationsblatt entfernt. Das Perforations­ blatt ist dann an sich fertig. Um jedoch die Stärke des Perforationsblatts zu mindern und seinen Perforationsumfang zu schärfen, wird durch zusätzliches Ätzen abschließend die Stärke des Perforationsblatts gemindert und sein Perfora­ tionsumfang geschärft. Entsprechend wird bei der Herstel­ lung eines Schneidblatts verfahren.To produce the perforation sheet, a steel sheet - preferably a thickness of 0.15 to 0.25 mm - is coated on both sides with a photoresist. The photo resist is exposed on at least one side of the steel sheet by means of a stencil which has line-shaped, opaque areas which are associated with the boundaries of the perforation wheel and can be seen in FIG. 3. The photoresist is cured in the exposed areas. The photoresist will wash off in the unexposed areas. Then the steel sheet in the unexposed areas is etched through to form the perforation sheet. Finally, the exposed areas of the photoresist are removed from the perforation sheet. The perforation sheet is then finished. However, in order to reduce the thickness of the perforation sheet and to sharpen its perimeter of perforation, the thickness of the perforation sheet is finally reduced by additional etching and its perforation perimeter is sharpened. The same procedure is followed in the manufacture of a cutting blade.
