Vorliegende Erfindung betrifft eine Vorrichtung, um Beutel für Börsen, Taschen und dergl. ohne Naht auf mechanischem Wege herzustellen.The present invention relates to a device to make pouches for purses, bags and like. Manufacture without a seam by mechanical means.
Die Benutzung der Vorrichtung erfolgt unter Anwendung der Kraft einer Presse.The device is used using the force of a press.
Fig. ι zeigt die perspectivische Ansicht der Vorrichtung in offenem Zustände, bevor das Leder für die Beutel eingelegt ist und bevor das Pressen begonnen hat. Fig. 2 zeigt die Ansicht der Vorrichtung in dem Augenblick, in welchem das Pressen des Leders c beginnt.Fig. Ι shows the perspective view of the device in the open state, before the leather is inserted for the bag and before the pressing has started. Fig. 2 shows the view of the device at the moment in which the pressing of the leather c begins.
Fig. 3 stellt einen Längsschnitt der Vorrichtung dar, wie sie sich zeigt, nachdem das Leder c durch den Stempel e in seine Form gebracht worden ist.Fig. 3 shows a longitudinal section of the device as it appears after the leather c has been brought into its shape by the punch e.
Die ganze Vorrichtung besteht aus vier Haupttheilen: dem massiven Stempel c, der Oberplatte a, der Unterplatte b und den vier Spiralfedern d nebst den dazu gehörigen Flügelmuttern i. The whole device consists of four main parts: the solid punch c, the upper plate a, the lower plate b and the four spiral springs d together with the wing nuts i belonging to them.
In den beiden Platten α und b befinden sich dem Stempel e entsprechende Oeffnungen k. In the two plates α and b there are openings k corresponding to the punch e.
An der Platte b sind vierFüfse/ angebracht, mit welchen das Werkzeug auf dem Schlitten der Presse ruht bezw. die Platte b san der Presse befestigt ist.Four feet / are attached to plate b , with which the tool rests or rests on the slide of the press. the plate b s is attached to the press.
Der Stempel e ist an dem Obertheil der Presse (an der Einschiebplatte der Presse) angeschraubt. An der Oberplatte α sind vier Schrauben g befestigt, welche durch die mit entsprechenden Löchern versehenen Winkel h gehen.The punch e is screwed to the upper part of the press (to the push-in plate of the press). Four screws g are attached to the top plate α , which go through the angles h provided with corresponding holes.
Vor dem Zusammenlegen der Platten α und b wird das Lederstück c, Fig. 2, auf die Unterplatte b gelegt. Die Schrauben g stehen nach dem Zusammenlegen von α und b durch die Winkel h heraus. Nun werden die losen Spiralfedern d von unten über die vorstehenden Schrauben g gesteckt und vermittelst der Flügelmuttern i angespannt, bezw. gegen den Winkel h gedrückt, wodurch ein federndes Festhaften der Platten α und b an einander bewirkt wird. Der federnde Druck, der je nach der Dicke des Leders geregelt werden kann, theilt sich dem Lederstück in seiner ganzen Fläche mit und läfst nicht zu, dafs, wenn der Stempel e auf das Leder (das sich also über der Oeffnung k befindet) drückt, sich irgend welche Falten bilden. Das Leder kann dadurch an einem Punkt dem Druck des Stempels nicht schneller folgen wie an einem anderen. Befände sich das Leder c nicht unter diesem federnden Druck, so würde es, sobald der Stempel e von oben her seinen steten Druck ausübt, entweder zerreifsen, oder es würde sich an den Stempel e nicht glatt anschmiegen und ringsum Falten bilden, also ein unbrauchbares Fabrikat ergeben.Before the panels α and b are put together , the piece of leather c, FIG. 2, is placed on the lower panel b . The screws g protrude through the angles h after the merging of α and b . Now the loose coil springs d are inserted from below over the protruding screws g and tightened by means of the wing nuts i , respectively. pressed against the angle h , whereby a resilient adherence of the plates α and b is caused to each other. The resilient pressure, which can be regulated depending on the thickness of the leather, shares its entire surface with the piece of leather and does not allow that when the stamp e presses on the leather (which is therefore located above the opening k ), any wrinkles form. As a result, the leather cannot follow the pressure of the stamp faster at one point than at another. If the leather c were not under this resilient pressure, as soon as the stamp e exerts its constant pressure from above, it would either tear, or it would not cling smoothly to the stamp e and form wrinkles all around, i.e. an unusable product result.
