Description

Gebrauchsmu. st ers chut zschrift- zur Anmeldung des Steppstich-Nahttrenners. , Gegenstand der Anmeldung ist ein Steppstich-Nahttrenner dadurch gekennzeichnet, dass durch ein Messer der Ober- faden abgeschnitten bzw. abgestossen-der Unterfaden unbeschädigt freigegeben und der Stoff nicht beschädigt wird. Beschreibung der Zeichnung. Abbildung 1 zeigt nach Linie a-b einen Längsschnitt. 'Der Pressfuss 1 ist mit dem Zylinder 5 starr verbunden. Im Zylinder 5 befindet sich der Kolben 3, in welchem das Trennmesser 10 durch die Stellschraube 2 nach Belie- ben verstellt werden kann. Teil 4, an welchem sich eine Druckfeder befindet, ist ebenfalls wie der Kolben 3 im Zylinder 5 verschiebbar gelagert. Zwischen dem Press- fuss 1 und dem Kolben 3 befindet sich die Druckfeder 8, die schwächer ist als die Druckfeder an dem Teil 4. Erklärung der Zeichnung. C-2 Die Sache gent nun in folgender ? eise vor sich. C> Der'Pressfuss 1 wird an die Drücker oder Pressstange : der Nähmaschine angeschraubt und die Nadelstange zu- CD gleich in den Zylinder 5 eingeführt. Ist dies gesehen hen, so k. nn mit der Trennung der Naht begonnen werden. Man bringt den Stoff mit der zu trennenden Naht durch Hochheben des Presshebels so unter den Pressfuss 1, dass di ? zu trsnnend ht vorne im Schiit-des Press- fusses 1 zu sehen ist. ? ird nun die Nähmaschine in Bewegung gesetzt, so ist die Folge, dass der Hub der der Nadelstange durch die Druckfeder am Teil4 und der Druckfeder 8 so reduzierend auf das Trennmesser im Kolben 3 übertragen wird, dass die Schneide des Messers 10 nur soweit über die Sohle des Pressfusses 1 heraus- geht, dass nur der Oberfaden abgeschnitten bzw. abge- CD stossen, der Unterfaden unbeschädigt freigegeben und t2 CD der Stoff nicnt beschädigt wir. Die Naht wird so schnell getrennt wie genäht. Utility first of all to register the lockstitch seam ripper. The subject of the application is a lockstitch seam ripper characterized in that the upper thread cut or repelled - the bobbin thread Released undamaged and the fabric not damaged will. Description of the drawing. Figure 1 shows a longitudinal section along the line from. The press foot 1 is rigidly connected to the cylinder 5. In the cylinder 5 is the piston 3, in which the cutting knife 10 through the adjusting screw 2 as required ben can be adjusted. Part 4, to which a The compression spring is also like the piston 3 in the Cylinder 5 slidably mounted. Between the press foot 1 and the piston 3 is the compression spring 8, which is weaker than the compression spring on part 4. Explanation of the drawing. C-2 The matter is now in the following? ice in front of you. C> The 'press foot 1 is attached to the pusher or press bar : screwed onto the sewing machine and the needle bar CD immediately introduced into the cylinder 5. Is this seen hen, so k. nn begin to separate the seam. You bring the fabric through with the seam to be separated Raise the press lever so under the press foot 1, that you? too trsnend ht in front in the Schiit-the press- foot 1 can be seen. ? The sewing machine will now be in Movement is set, the consequence is that the stroke of the the needle bar by the compression spring on part 4 and the Compression spring 8 so reducing on the cutting knife in Piston 3 is transferred that the cutting edge of the knife 10 only far beyond the sole of the press foot 1 that only the upper thread is cut or CD push, the bobbin thread is released undamaged and t2 CD the fabric is not damaged. The seam is going so fast separated like sewn.
