Description
Verfahren und Maschine zum Schneiden von Gummi Das Schneiden und Spalten von Gummi ist wegen der Eigenart dieses Werkstoffes sehr schwierig, da er unporös und volumetrisch nicht zusammendrückbar, dabei aber äußerst elastisch ist, so daß er sich gegen das Messer festzuklemmen und es durch Reibung stark zu erhitzen sucht. Daher muß man bisher selbst für sehr kleine Schnitte reichliche Wasserschmierung oder andere Kunstgriffe verwenden.Method and machine for cutting rubber The cutting and splitting Due to the nature of this material, rubber is very difficult because it is non-porous and not volumetrically compressible, but is extremely elastic, so that he tries to clamp himself against the knife and tries to heat it up by friction. Therefore, up to now, it has been necessary to have ample water lubrication even for very small cuts or use other contrivances.
Die Schwierigkeiten wachsen, wenn es sich um große Schnittflächen handelt, deren Ausdehnung sich nach Quadratmetern bemißt.Difficulties increase when the cut surfaces are large acts, the extent of which is measured in square meters.
Die Erfindung vermeidet diese Nachteile und ermöglicht gegebenenfalls die Weglassung jedweder Wasserschmierung o. dgl. durch eigenartige Anwendung und sinngemäße Anpassung eines in der Lederspalterei üblichen Verfahrens unter Berücksichtigung der obigen Eigenschaften des Gummis gegenüber dem Leder, das ein poröser, volumetrisch zusammendrückbarer und relativ unelastischer Stoff ist.The invention avoids these disadvantages and, if necessary, enables the omission of any water lubrication or the like. By peculiar application and analogous adaptation of a procedure customary in leather splitting, taking into account the above properties of the rubber compared to the leather, which is a porous, volumetric is compressible and relatively inelastic fabric.
Die Erfindung beseitigt die vorerwähnten Schwierigkeiten dadurch, daß eine dicke Gummiplatte zwischen Preßwalzen hindurchgeführt und von ihr beim Austritt aus dem Eingriff der Walzen eine dünne Schicht durch ein längs der Walzen und konstant in derselben Richtung bewegtes Messer in der Weise abgeschnitten wird, daß die Schneidlinie in einer Spannungszone wesentlich parallel und nahe der durch die Achsen beider Walzen gehenden Ebene verläuft.The invention overcomes the aforementioned difficulties by that a thick rubber sheet passed between press rollers and from her when A thin layer emerges from the engagement of the rollers through a length of the rollers and knife moving constantly in the same direction is cut off in such a way that the cutting line in a stress zone is substantially parallel and close to the through the axes of both rollers running plane runs.
Auf diese Weise lassen sich außerordentlich rasch und billig dünne große Platten für Fußbodenbelag u. dgl. von stärkeren Gummistücken abspalten.In this way, thinning can be carried out extremely quickly and cheaply Separate large plates for flooring and the like from thicker pieces of rubber.
Ganz besonders groß werden die Vorteile der Erfindung bei Herstellung gemusterter Platten für Fußbodenbelag usw. Solche gemusterten Platten werden bisher aus verschiedenfarbigen Stückchen zusammengekittet, deren Dicke, ungefähr der herzustellenden Platte entspricht, was bei dünnen Platten schwierig und teuer ist.The advantages of the invention during manufacture are particularly great patterned panels for flooring, etc. Such patterned panels are heretofore cemented together from different colored pieces, the thickness of which is approximately that to be produced Plate corresponds to what is difficult and expensive with thin plates.
Die Erfindung vermeidet diese Nachteile dadurch, daß zunächst ein starkes Vorwerkstück durch das bekannte Zusammenfügen verschieden gefärbter Teile aus schön mehr oder minder vulkanisiertem Gummi hergestellt wird. Von diesem Vorwerkstück werden dann erfindungsgemäß dünne gemusterte Platten abgespalten.The invention avoids these disadvantages by initially having a Strong preliminary work piece due to the known joining of different colored parts is made of nicely more or less vulcanized rubber. From this preliminary workpiece thin patterned plates are then split off according to the invention.
In der Zeichnung ist ein - Ausführungsbeispiel einer Maschine zur Ausübung des Verfahrens schematisch im -lotrechten Schnitt dargestellt.In the drawing is an - embodiment of a machine for Exercise of Procedure shown schematically in -vertical section.
Für .das Verfahren wird eine dicke Gummiplatte 16 benutzt, die vorzugsweise durch Zusammenfügung verschieden gefärbter Gummimassen gebildet ist.For. The method a thick rubber sheet 16 is used, which is preferably is formed by joining different colored rubber compounds.
Zwei Führungswalzen 3z, 33 haben solchen Abstand relativ zur Dicke der Platte, daß sie dieselbe beim Durchgange fest zwischen sich fassen und an der Stelle x um mindestens 3 a/o auf das Maß A zusammendrücken. In der dadurch geschaffenen Spannungszone y schneidet ein über zwei Riemenscheiben längs der Walzen konstant in derselben Richtung laufendes Bandmesser 3 5, das sich gegen ein durch Schraube 36 nachstellbares Widerlager 37 stützt und in einer Führung 34 läuft. Die Schneidkante dieses Messers verläuft parallel und nahe der durch die Achsen beider Walzen gehenden Ebene merklich versetzt gegen die Mittellinie des Walzeneingriffs. Die abgespaltene gemusterte Platte 4o läuft über die Oberfläche 38 der Führung, während die Restplatte 41 an der Unterfläche 39 der Führung entlang läuft.Two guide rollers 3z, 33 have such a distance relative to the thickness the plate so that they grasp it firmly between them during passage and on the Compress point x by at least 3 a / o to dimension A. In the resulting Tension zone y cuts a constant over two pulleys along the rollers in the same direction running band knife 3 5, which is against a screw 36 adjustable abutment 37 is supported and runs in a guide 34. The cutting edge this knife runs parallel to and close to the one passing through the axes of both rollers Level noticeably offset from the center line of the roller engagement. The split off patterned plate 4o runs over the surface 38 of the guide, while the rest of the plate 41 runs along the lower surface 39 of the guide.
Nach dem Spalten können die Schnittflächen der Plattelf geglättet oder poliert, z. B. geschliffen, werden. Auch kann ein Nachvulkanisieren stattfinden, wobei natürlich die Schnittfläche in Berührung mit einer glatten Oberfläche gehalten wird.After splitting, the cut surfaces of the flat eleven can be smoothed or polished, e.g. B. be ground. Post-vulcanization can also take place, the cut surface being of course kept in contact with a smooth surface will.
