- Such a sewing machine is known from the DE 101 17 560 C1 , To prevent rotation in sewing operation direction of rotation is a housing projection of the bobbin case on a housing-fixed spring bar. To prevent rotation of the bobbin case in the opposite direction is another projection of the bobbin case on a cam of a cantilever.
- This cantilever requires space between the bobbin case and the platen, which is not available for the thread-pulling knife. This requires a complex production, in particular a special hardening of the components arranged in this area, the size of which is very limited.
- the cantilever requires an additional vertical distance between a platen, are guided by the needle and looper thread and the looper thread feeding the bobbin case, resulting in a threadline still in need of improvement.
- the cantilever hinders with its anti-rotation stop the threadline especially when the thread-pulling knife is present in a pivoted to a basic position thread detection position.
- the anti-rotation stop for securing the bobbin case against rotation in the opposite direction directly on the thread-pulling knife.
- An additional cantilever or web to provide this anti-rotation lock omitted, so that space can be saved, which in turn is the other components in this area of the sewing machine available. Since the second anti-rotation stop is forcibly pivoted with the thread-pulling knife due to the determination on the thread-pulling knife, this second anti-rotation stop is automatically no longer in the way of the thread run in the thread-detecting position of the thread-pulling knife.
- the coil housing can be with less vertical distance to the support plate can be arranged, which allows shorter after sewing on the fabric remaining yarn ends and also has a positive effect on the yarn path after the cutting process.
- the position assurance device ensures that the thread-pulling knife can absorb required forces from the bobbin case in the basic position for the rotational security.
- a second anti-rotation stop according to claim 2 is particularly compact.
- An opposing approach according to claim 3 ensures that this approach does not interfere with the yarn path.
- a deflection mechanism ensures that whenever the thread-pulling knife is to be moved into the thread-detecting position via the thread-pulling knife drive, the securing of the thread-pulling knife in the basic position is canceled.
- a deflection mechanism according to claim 5 comes with advantageously few components and is at the same time reliable.
- Securing sections according to claim 6 can be produced inexpensively.
- a thread-pulling knife drive according to claim 7 requires only a small effort.
- a thread-pulling knife drive according to claim 8 has proven itself in practice.
- a biasing spring according to claim 9 ensures a return of the deflection mechanism in the securing position.
- a biasing spring according to claim 10 is inexpensive.
- the thread-pulling knife has a lengthened and rounded free end section. This prevents that in particular the needle thread in the loop formation is undesirable caught on the thread-pulling knife or other sewing machine components and also ensures that in particular the needle thread does not unwanted wrapped around the thread-pulling knife.
- This embodiment of the thread-pulling knife with the extended and rounded free end portion is also independent of the design of the anti-rotation device for the bobbin case to prevent disturbance of the threadline of advantage.
- the thread-pulling knife with the extended and rounded free end portion is therefore an independent from the other sewing machine components advantageous subject of the invention.

Es ist eine Aufgabe der vorliegenden Erfindung, eine Doppelsteppstichnähmaschine der eingangs genannten Art derart weiterzubilden, dass für die einzelnen Komponenten im Bereich des Fadenlaufs zwischen dem Spulengehäuse und der Auflageplatte weniger anspruchsvolle Bauraumanforderungen gestellt werden, wobei zudem nach Möglichkeit eine Beeinträchtigung des Fadenlaufs insbesondere in der Fadenerfassungsstellung des Fadenziehmessers vermieden werden soll.It is an object of the present invention, a lockstitch sewing machine of the type mentioned in such a way that less demanding space requirements are made for the individual components in the region of the yarn path between the bobbin case and the support plate, wherein also, if possible, an impairment of the yarn path, especially in the thread detection position of the thread-pulling knife should be avoided.
Diese Aufgabe ist erfindungsgemäß gelöst durch eine Doppelsteppstichnähmaschine mit den im Kennzeichnungsteil des Anspruchs 1 angegebenen Merkmalen.This object is achieved by a lockstitch sewing machine with the features specified in the characterizing part of claim 1.
Erfindungsgemäß wurde erkannt, dass es möglich ist, den Drehsicherungsanschlag für die Sicherung des Spulengehäuses gegen eine Verdrehung in der Gegenrichtung direkt am Fadenziehmesser vorzusehen. Ein zusätzlicher Kragarm oder Steg zur Bereitstellung dieser Gegen-Drehsicherung entfällt, so dass Bauraum gespart werden kann, der wiederum den anderen Komponenten in diesem Bereich der Nähmaschine zur Verfügung steht. Da der zweite Drehsicherungs-Anschlag aufgrund der Festlegung am Fadenziehmesser zwangsweise mit dem Fadenziehmesser verschwenkt, steht dieser zweite Drehsicherungs-Anschlag dem Fadenlauf in der Fadenerfassungsstellung des Fadenziehmessers automatisch nicht mehr im Wege. Das Spulengehäuse kann mit geringerem vertikalen Abstand zur Auflageplatte angeordnet werden, was nach dem Abschneidevorgang kürzere am Nähgut verbleibende Fadenenden ermöglicht und sich zudem positiv auf den Fadenlauf auswirkt. Die Positionssicherungseinrichtung stellt dabei sicher, dass das Fadenziehmesser in der Grundstellung für die Drehsicherung erforderliche Kräfte vom Spulengehäuse aufnehmen kann.According to the invention it was recognized that it is possible to provide the anti-rotation stop for securing the bobbin case against rotation in the opposite direction directly on the thread-pulling knife. An additional cantilever or web to provide this anti-rotation lock omitted, so that space can be saved, which in turn is the other components in this area of the sewing machine available. Since the second anti-rotation stop is forcibly pivoted with the thread-pulling knife due to the determination on the thread-pulling knife, this second anti-rotation stop is automatically no longer in the way of the thread run in the thread-detecting position of the thread-pulling knife. The coil housing can be with less vertical distance to the support plate can be arranged, which allows shorter after sewing on the fabric remaining yarn ends and also has a positive effect on the yarn path after the cutting process. The position assurance device ensures that the thread-pulling knife can absorb required forces from the bobbin case in the basic position for the rotational security.

Das Fadenziehmesser hat einen verlängerten und abgerundet gestalteten freien Endabschnitt. Hierdurch ist verhindert, dass insbesondere der Nadelfaden bei der Schlingenbildung sich unerwünscht am Fadenziehmesser oder anderen Nähmaschinenkomponenten verfängt und zudem sichergestellt, dass insbesondere der Nadelfaden sich nicht unerwünscht um das Fadenziehmesser wickelt. Diese Ausgestaltung des Fadenziehmessers mit dem verlängerten und abgerundeten freien Endabschnitt ist auch unabhängig von der Gestaltung der Drehsicherung für das Spulengehäuse zur Verhinderung einer Störung des Fadenlaufes von Vorteil. Das Fadenziehmesser mit dem verlängerten und abgerundeten freien Endabschnitt stellt daher einen von den sonstigen Nähmaschinenkomponenten unabhängigen vorteilhaften eigenen Erfindungsgegenstand dar.The thread-pulling knife has a lengthened and rounded free end section. This prevents that in particular the needle thread in the loop formation is undesirable caught on the thread-pulling knife or other sewing machine components and also ensures that in particular the needle thread does not unwanted wrapped around the thread-pulling knife.
