Description
Verfahren zur Herstellung einer schmalen Naht mittels einer Bogennadel für Schuhwerk o. dgl. Bei den bekannten Verfahren zur Herstellung einer schmalen Naht zum Verbinden zweier in einer oder ungefähr einer Ebene liegenden Werkstückteile mittels einer Bogennadel mit Ein- und Ausstich auf derselben Seite des Werkstückes für Schuhwerk o. dgl. liegt die Nadelebene in einem Winkel von go° zur gebildeten Naht oder zur Vorschubrichtung des Werkstückes.Method for producing a narrow seam using a bow needle for footwear o. The like. In the known method for producing a narrow Seam for joining two workpiece parts lying in one or approximately one plane by means of a curved needle with a puncture and a cutout on the same side of the workpiece For footwear or the like, the needle plane is at an angle of go ° to the one formed Seam or to the feed direction of the workpiece.
um nun eine gewisse Festigkeit in einem weichen Material zu erhalten, muß die Nadel genügend Stoff fassen, was zur Folge hat, ,daß Ein- und Ausstich in einem größeren Abstand voneinander erfolgen. In order to obtain a certain degree of strength in a soft material, the needle must hold enough material, which means that the insertion and removal take place at a greater distance from one another.
Dieser große Abstand, der in Fachkreisen als breiter Stich bekannt ist, hat den Nachteil, daß er das 'Material senkrecht zur Sohlenkante zusammenzieht, wodurch sich parallel zur Sohlenkante je nach der Breite des Stiches und der Materialbeschaffenheit eine Wulst bildet, die ;beim Tragen der Schuhe als unangenehm empfunden wird.This large distance, known in specialist circles as the wide stitch has the disadvantage that it pulls the material together perpendicular to the edge of the sole, whereby it is parallel to the edge of the sole depending on the width of the stitch and the nature of the material forms a bulge that is felt to be uncomfortable when wearing the shoes.
Das Verfahren des breiten Stiches wird deshalb auch bei feinen und weichen Werkstoffen nicht angewandt, da der Schuh durch die breite Naht ein schlechtes Aussehen erhält.The method of the wide stitch is therefore also used for fine and soft materials are not used, as the shoe is bad because of the wide seam Appearance.
Das neue Verfahren verfolgt den Zweck, die Breite des Stiches so zu verringern, daß obige Nachteile behoben werden.The purpose of the new process is to increase the width of the stitch reduce that the above disadvantages are remedied.
Um diesen Zweck zu erreichen, schwingt gemäß der Erfindung die Nadel in einer Ebene aus, die die Vorschubrichtung unter einem Winkel schneidet, der kleiner als 9o° ist.To achieve this purpose, according to the invention, the needle vibrates in a plane that intersects the feed direction at an angle that is smaller than 9o °.
Der Abstand des Ein- und Ausstiches läßt sich hierbei bis auf Null herunterdrücken, wenn Ein- und Ausstich parallel zur Sohlenkante erfolgen. Der erzeugte Stich bildet alsdann eine gerade Linie.The distance between the piercing and the piercing can be reduced to zero Press down if the stitches are parallel to the edge of the sole. The generated The stitch then forms a straight line.
Der Erfindungsgegenstand ist auf beiliegender Zeichnung veranschaulicht.The subject matter of the invention is illustrated in the accompanying drawing.
Fig. i zeigt beispielsweise Sohle und Schaft, auf welchem eine Brandsohle mit dem neuen Stich verbunden ist, in Perspektive. Fig.2 zeigt dasselbe senkrecht von oben gesehen. Die Art des Stiches ist ein l;lberwendlichstich.Fig. I shows, for example, the sole and upper on which an insole associated with the new stitch, in perspective. Fig.2 shows the same vertically seen from above. The type of stitch is an overcast stitch.
Fit". 3 zeigt die Verbindung von Sohle und Schaft mittels Kettenstichs.Fit ". 3 shows the connection between the sole and the upper by means of a chain stitch.
In Fig. i und 2 tritt die Nadel in Punkt 5 unter dem Winkel a zur Sohlenkante in die Brandsohle ein und bei Punkt g wieder heraus, wobei die Schleife 8 durch das Werkstück gezogen wird. Alsdann wird die Schleife 8 im Winkel von go° zur Sohlenkante auf den Schaft 3 und die Brandsohle i gelegt, so daß die Nadel in Punkt io .durch de Schleife 8 einen neuen Einstich wie vorher ausführt.In Fig. I and 2, the needle occurs in point 5 at the angle α to Edge of the sole into the insole and out again at point g, with the loop 8 is pulled through the workpiece. Then the loop 8 is at an angle of go ° to the edge of the sole on the shaft 3 and the insole i so that the needle in Point io. Through the loop 8, a new puncture is carried out as before.
In Fig. 3 tritt die Nadel ebenfalls unter einemWinkel, kleiner als go° zur Sohlenkante, in Punkt i i in den Schaft ein und in Punkt 13 wieder heraus, wobei die Schleife 12 mittels der \Tadel ebenfalls durch das Werkstück gezogen wird. Die Schleife 12 wird alsdann parallel zur Sohlenkante auf .das Werkstück i gelegt und so lange dort festgehalten, bis beim Ausstich der Nadel im Punkt 16 die neu gebildete Schleife 17, .die durch die Schleife 12 gezogen wird, dieselbe festhält.In Figure 3, the needle also enters at an angle less than go ° to the edge of the sole, in point i i into the shaft and out again in point 13, whereby the loop 12 is also pulled through the workpiece by means of the \ Tadel. The loop 12 is then placed on the workpiece i parallel to the edge of the sole and held there until the new one when the needle sticks out at point 16 formed loop 17,. which is pulled through the loop 12, the same holds.
