KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Nach vorliegender Erfindung wird ein von einem Gummiwalzwerk gewöhnlicher Art geliefertes endloses Gummiband einer beträchtlichen Abkühlung unterworfen; die hierbei auftretende Zusammenziehung des Gummis hat zur Folge, dafs die auf der Schneidmaschine ausgeschnittenen Stücke sich bei der nachfolgenden Verarbeitung nicht mehr zusammenziehen können und somit das bei der bisherigen Fabrikation von Gummischuhen so lästige Schwinden des Gummis bei der späteren Verarbeitung vermieden wird.According to the present invention, there is provided an ordinary type of rubber mill endless elastic undergoes considerable cooling; the resulting contraction of the rubber As a result, the pieces cut out on the cutting machine will be in the next Processing can no longer contract and thus with the previous manufacture of rubber shoes annoying shrinkage of the rubber during later processing is avoided.
Das Gummiband geht alsdann sammt dem : Transporttuch durch eine Schneidmaschine, ; welche aus dem Gummiband Stücke von geeigneter Gröfse und Gestalt ausschneidet. ; Die beiliegende Zeichnung zeigt eine Vorrichtung zur Ausführung des angegebenen Ver-; • fahrens.The rubber band then goes through a cutting machine together with the: transport cloth ; which cuts out pieces of suitable size and shape from the rubber band. ; The accompanying drawing shows a device for performing the specified Ver; • driving.
Das am besten aus hartem Kautschuk mit Leinwandeinlage bestehende Transporttuch A. führt das aus dem Gummiwalzwerk kommende endlose Gummiband in die Kühlvorrichtung, wo das Gummiband bis auf nahezu o° C. abgekühlt wird, damit es sich zusammenziehen und im kalten, zusammengezogenen Zustand der Operation des Schneidens unterworfen werden kann, so dafs die ausgeschnittenen Stücke sich bei der weiteren Verarbeitung nicht ; zusammenziehen (schwinden) können. : Die in der Zeichnung dargestellte Aüs- ) führungsform der Kühlvorrichtung besteht aus einem in einem Gestell B* angeordneten ·. ■:"." ■■■·../■■'.■.- The transport cloth A. , which is best made of hard rubber with a canvas insert, guides the endless rubber band coming from the rubber rolling mill into the cooling device, where the rubber band is cooled down to almost 0 ° C. so that it can contract and in the cold, contracted state of the operation Can be subjected to cutting so that the cut pieces do not move in further processing; can contract (shrink). The Aüs-) shown in the drawing guide die of the cooling device consists of a * arranged in a frame B ·. ■: "." ■■■ · ../ ■■ '. ■ .-
Trog B, durch welchen das Gummiband mit dem Transporttuch A über Leitwalzen b geführt wird. In diesen, am besten mit reinem Wasser gefüllten Trog taucht, ohne die Bewegung des Gummibandes und Transporttuches zu hindern, ein zweiter Trog B2, der mit Salzlösung gefüllt ist und in welchen ein dritter Trog B1 taucht, der eine durch ein Rührwerk B3 in beständiger Bewegung erhaltene Kältemischung von irgend einer bekannten Zusammensetzung enthält.Trough B, through which the rubber band with the transport cloth A is guided over guide rollers b. In this, a second trough appeared best filled with pure water trough, without the movement of the rubber tape and transport cloth to prevent, B 2, which is filled with saline solution and in which a third trough B 1 dive, a by an agitator B 3 contains cold mixture obtained in constant motion, of any known composition.
Durch diese Kältemischung im Trog B1 wird die Salzlösung im Trog B2 von oben und daher sehr rasch abgekühlt und beständig kalt erhalten, ohne dafs es nöthig wäre, für die Salzlösung ein besonderes Rührwerk anzuordnen. Die Salzlösung kühlt wieder ihrerseits ebenso rasch und ausgiebig das Wasser im Trog B ab. Die Bewegung des Gummibandes und Transporttuches im Trog B trägt dadurch, dafs sie auch dem Wasser mitgetheilt wird,· wesentlich dazu bei, die Temperatur des letz-, teren gleichmäfsig niedrig zu erhalten.As a result of this cold mixture in trough B 1 , the salt solution in trough B 2 is cooled from above and therefore very quickly and kept constantly cold, without it being necessary to arrange a special agitator for the salt solution. The salt solution in turn cools the water in trough B just as quickly and extensively. The movement of the rubber band and the transport sheet in trough B , because it is also communicated to the water, contributes significantly to keeping the temperature of the latter evenly low.
Die Zwischenschaltung des Troges B2 zwischen den Trog B und den Trog B1 ist nicht unbedingt nothwendig, ist aber empfehlenswerth, weil hierdurch die Entleerung des Troges B1 und seine Neufüllung vorgenommen werden kann, ohne dafs man befürchten müfste, dafs das Gummiband während dieser Zeit weniger vollständig abgekühlt würde. !The interposition of the trough B 2 between the trough B and the trough B 1 is not absolutely necessary, but it is recommended because this allows the emptying of the trough B 1 and its refilling without having to fear that the rubber band will break during this Time would be less fully cooled. !
Der Trog B braucht übrigens nicht nothwendig mit Wasser gefüllt zu sein, er kann Incidentally, trough B does not necessarily have to be filled with water, it can
auch einfach Luft enthalten, nur mufs dann der Weg des Gummibandes durch diesen Trog entsprechend langer sein.also simply contain air, only then the path of the elastic band has to go through this trough be correspondingly longer.
Von der Kühlvorrichtung führt das Transporttuch A das Gummiband zur Schneidmaschine. The transport cloth A leads the rubber band from the cooling device to the cutting machine.
