Description

Vorrichtung zum Herstellen von Gummischuhen o. dgl. durch Pressen, Es ist bekannt, Gummischuhe u. dgl. durch Pressen roh zugeschnittener unvulkanisierter Kautschukplatten herzustellen, die außen auf einem z. $. mit einem Innenschuh aus Futterstoff o. dgl. bekleideten Preßleisten angebracht sind, und zwar so, daß die vorbereiteten Kautschukplatten durch erwärmte, auf den bekleideten Leisten zu nach innen bewegte Seitenformen in Verbindung mit einer oder mehreren Sohlenformen dazu gebracht werden, die Gestalt des Außengummis des Gummischuhwerks anzunehmen.Device for producing rubber shoes or the like by pressing, It is known to use rubber shoes and the like that have been roughly cut to size by pressing Manufacture rubber sheets that are on the outside on a z. $. with an inner shoe Lining o. The like. Clad pressure strips are attached, in such a way that the prepared rubber sheets through heated, on the clad ledges side shapes moved inside in connection with one or more sole shapes are brought to assume the shape of the outer rubber of the rubber footwear.

Um das Falten des Futters zu vermeiden, das am Absatz- und Zehenteil des Gummischuhwerks entsteht, wenn man nur zwei Seitenformen benutzt, die je einer halben Seitenfläche des Schuhwerks entsprechen und deshalb während des Pressens unmittelbar gegeneinander nach innen bewegt werden, hat man schon vorgeschlagen, vier oder mehr Seitenformen zu verwenden, die in gegenseitig konvergierenden Richtungen auf den Leisten zu und von demselben fort geführt werden.To avoid creasing the lining on the heel and toe parts of the rubber footwear is created when you only use two side molds, one each half the side surface of the footwear and therefore during pressing be moved inwards directly against each other, it has already been suggested that use four or more side shapes that are in mutually converging directions on the ledge to and away from it.

Die Erfindung betrifft eine Vorrichtung zur Herstellung von Gummischuhwerk durch Pressen zwischen einem Leisten und auf diesen zu nach innen bewegten Seitenformen in Verbindung mit einer oder mehreren Sohlenformen. und besteht darin, daß die zum Pressen des Gummischuhwerks - verwendete Vorrichtung drei Seitenformen hat, die auf den Leisten zu und von demselben fort konvergierend von drei verschiedenen Seiten geführt werden, Indem man das Pressen --der zugeschnittenen unvulkanisierten Kautschukplatten, welche den Preßleisten umgeben, durch eine oder mehrere Sohlenformen und drei konvergierend von drei verschiedenen Seiten auf den Leisten zu und von demselben fort geführten Seitenformen ausführt, soll auf möglichst einfache Weise eine entsprechende Wirkung, wie durch die Anwendung von vier oder mehr Seitenformen, die sich nach innen auf den Leisten zu und von demselben fort nach gegenseitig konvergierenden Richtungen bewegen, erzielt werden. Die drei erwähnten Seitenformen werden so auf den Leisten-zu bewegt, daß die in die Gestalt des Außengummis des Schuhwerks zu pressende kautschukmasse überall Drücken ausgesetzt wird, die eine nach innen gegen das Innere des Leistens gerichtete Richtungskomponente haben, und die Folge hiervon ist, daß die Kautschukmasse in allen Punkten der Seitenfläche des Schuhwerks Preßdrucken unterworfen wird,. die nach innen auf den Leisten zu gefichtet sind und die. innere Futterschicht festhalten, wodurch eine Verschiebung der inneren Futterschicht während des Pressens verhindert und insbesondere ihrer Neigung entgegengewirkt wird, am Absatz- und Zehenteil Falten zu bilden, wie es der Fall ist, wenn nur zwei unmittelbar gegeneinander.geführte Seitenformen benutzt werden. Bei Anwendung von drei Seitenformen, die während des Pressens von dreiverschiedenen Seiten konvergierend nach innen auf den Leisten zu geführt werden, soll ferner vermieden werden, daB an irgendeinem Punkte der Seitenfläche dies Schuhwerks eine Formbewegung stattfindet, die tangential zu der auf dem Gummischuhwerk zu formenden Oberfläche ist, und man erreicht mit Sicherheit, daB überall auf der Seitenfläche PreBdrucke auftreten, die durch eine Bewegung der Formflächen der Seitenformen nach innen auf den Leisten zu erzeugt worden sind.The invention relates to a device for manufacturing rubber footwear by pressing between a bar and side molds moved inwardly towards this in connection with one or more sole shapes. and consists in the fact that the Pressing the rubber footwear - the device used has three side shapes that on the ledges to and from it converging from three different sides can be performed by pressing - the cut unvulcanized rubber sheets, which surround the pressure bar, by one or more sole shapes and three converging led to and from the ledge from three different sides Executes side shapes, should have a corresponding effect in the simplest possible way, like by applying four or more side shapes that face inward the ledges to and from it in mutually converging directions move, be achieved. The three side shapes mentioned are so close to the groin moves that the rubber mass to be pressed into the shape of the outer rubber of the footwear everywhere pressures are exposed, one inward against the inside of the last have directed directional component, and the consequence of this is that the rubber mass is subjected to press pressure in all points of the side surface of the footwear. which are aligned inwards on the ledges and which. hold the inner lining, thereby preventing the inner lining layer from shifting during pressing and in particular their tendency is counteracted, creases on the heel and toe part to form, as is the case when only two directly against each other Side shapes to be used. When using three side molds, which during the pressing of three different sides converging inwards on the ledge, should also be avoided that this footwear at any point on the side surface a molding movement takes place which is tangential to that to be molded on the rubber footwear Surface is, and one reaches with certainty that everywhere on the side surface PreBrucke occur, which are caused by a movement of the mold surfaces of the side molds on the inside of the strips.
