Description

Rillenschneider für Gummireifen Es gibt Werkzeuge zum Schneiden von Rillen in Gummireifen, bei denen ein U-förmiges Messer an einem Halter auswechselbar befestigt ist. Gemäß der Erfindung ist nun das Messer zwischen einer festen und einer losen Schiene eingespannt und sind zwischen den Schenkeln des Messers nach der Breite der zu schneidenden Rillen bemessene Zwischenplatten angeordnet. Dadurch wird erreicht, daß ein einziges Messer für verschiedene Rillenbreiten benutzt werden kann, während bisher verschieden breite Messererforderlich waren. In der Zeichnung ist die Erfindung veranschaulicht, und zwar zeigen die Fig. i und 2 den Rillenschneider in zwei Ansichten; Fig.3 zeigt die Befestigungsteile und Fig. q. das Messer. Der Rillenschneider besteht aus einem Stück Flacheisen, das an einem Ende einen Griff hat und am anderen durchgekröpft ist. An diesem Ende ist das Messer g zwischen der festen Schiene f und losen Platten, c, d mit zwei Schrauben s festgespannt. Zwischen den Platten kann das Messer tiefer und höher -eingestellt werden. Zwischen den Schenkeln des Messers ist eine Platte e angeordnet, durch welche die Breite der zu schneidenden Rillen bestimmt wird. Die Platte kann verschieden dick sein, man kann auch mehrere Platten verwenden, z. B. die Platten e und d. Das Messer g ist ein schwaches Stückchen Flachstahl, das einseitig (Innenseite) geschliffen und dann zu einem U gebogen ist. Zum Schneiden von Rillen in abgefahrene Gummireifen zieht man das Messer in der gewünschten Richtung durch den Reifen.Groove cutter for rubber tires There are tools for cutting grooves in rubber tires in which a U-shaped knife is attached to a holder in an exchangeable manner. According to the invention, the knife is now clamped between a fixed and a loose rail and intermediate plates are arranged between the legs of the knife according to the width of the grooves to be cut. It is thereby achieved that a single knife can be used for different groove widths, while knives of different widths were previously required. The invention is illustrated in the drawing, namely FIGS. I and 2 show the groove cutter in two views; Fig.3 shows the fastening parts and Fig. Q. the knife. The groove cutter consists of a piece of flat iron that has a handle at one end and is cranked at the other. At this end the knife g is clamped between the fixed rail f and loose plates, c, d with two screws s. The knife can be adjusted lower and higher between the plates. A plate e is arranged between the legs of the knife, by means of which the width of the grooves to be cut is determined. The plate can be of different thicknesses, you can also use several plates, z. B. the plates e and d. The knife g is a weak piece of flat steel that is ground on one side (inside) and then bent into a U. To cut grooves in worn rubber tires, pull the knife in the desired direction through the tire.
