Description

Vorrichtung für Nähmaschinen zum Herstellen einer Blindstichnaht In dem Hauptpatent 657 768 ist eine Vorrichtung für Nähmaschinen zum Herstellen einer Blindstichnaht beschrieben, bei der die zu verbrodenden Stofflagen um einen Führungsstab gelegt und mit diesem an den Nähwerkzeugen vorbeigeführt werden, wobei eine Ausnehmung in der zu den Nähwerkzeugen. ein- und feststellbaren Nähfußsohle zur Führung des Stabes dient.Device for sewing machines for producing a blind stitch seam In the main patent 657 768 is a device for sewing machines for producing a Blind stitch seam described in which the layers of fabric to be burnt around a guide rod placed and guided past the sewing tools with this, with a recess in the one to the sewing tools. adjustable and lockable presser foot sole for guiding the Rod serves.

In dieser Ausführungsform wird die Vorrichtung im allgemeinen nur zur Herstellung von geradlinig verlaufenden Blindstichnähteu verwendet. Da jedoch für bestimmte Schneiderarbeiten auch die Anfertigung bogenförmig verlaufender BLindstichnähte erwünscht und erforderlich ist, soll durch vorliegende Zusatzerfindung die Herstellung auch solcher gekrümmter oder bogenförmiger Nähte ermöglicht werden.In this embodiment, the device is generally only Used to produce straight blind stitch seams. However, since for certain tailoring work also the production of curved blind stitch seams is desired and necessary, the present additional invention is intended to be the production such curved or arched seams are also made possible.

Dies geschieht in einfachster Weise dadurch, daß der Stofführungsstab eine gebogene Form von verhältnismäßig großem Krümmungshalbmesser .erhält.This is done in the simplest way by the fact that the cloth guide rod a curved shape with a relatively large radius of curvature.

In der Zeichnung ist in Abb. i und i a ein solcher gebogener Führungsstab allein bzw. in die Ausnehmung der Nähfußsohle eingelegt im Grundriß dargestellt. Abb.2 veranschaulicht ein damit hergestelltes Arbeitsstück mit bogenförmigen Nähten. Die Abb. i a zeigt, daß für den neuen gekrümmten Führungsstab ei die gleiche Nähfußsohle wie für den geraden Stab des Hauptpatents zu verwenden ist. Die gewölbeartige Ausnehmung c der Nähfußsohle a nimmt, trotzdem sie geradlinig verläuft, den gebogenen Stab e1 bequem auf, da sich dessen Krümmung infolge des verhältnismäßig großen Krümmungshalbmessers auf die kurze Strecke der geraden Führung in der Nähfußsohle kaum bemerkbar macht.In the drawing, such a curved guide rod is shown in Figs. I and i a shown alone or inserted in the recess of the presser foot sole in plan. Fig. 2 illustrates a work piece with arcuate seams made with it. Fig. 1a shows that the same presser foot sole is used for the new curved guide rod how to use for the straight bar of the main patent. The vault-like recess c of the presser foot sole a, although it is straight, takes the curved rod e1 comfortably, since its curvature is due to the relatively large radius of curvature barely noticeable on the short distance of the straight guide in the presser foot sole.

Es wird also durch vorliegende Erfindung der Arbeitsbereich der im Hauptpatent dargestellten Vorrichtung erheblich erweitert und die Vorrichtung dadurch wesentlich verbessert.The working area of the im Main patent shown device expanded considerably and the device thereby much improved.
