Description
Nähfuss für Nähmaschinen Die vorliegende Erfindung bezieht sieh auf einen Nähfuss für Nähmaschinen -und er möglieht die Zuleitung von Kühlluft oder von Flüssigkeiten auf die Nähstelle und auf die Nadel, indem erfindungsgemäss vorgesehen ist, dass der Nähfuss Kanäle aufweist, durch wel- ehe während des Betriebes flüssige oder gas förmige Stoffe in :die Nadeldurchtrittsöffnung gefördert werden können.
Zwei Ausführungsbeispiele des Erfin- dungsgegenstandes sind in der Zeichnung dar- gestellt. Es zeigen: Fig. 1 einen Grundriss des teilweise ge- sehnittenen Nähfusses.
Fig. 2 einen Längsschnitt gemäss der Linie 11-II von Fig. 1, Fig. 3 einen Querschnitt nach der Linie 111-III von Fig. 2, Fig. 4 den Gmlndriss einer Variante. Der Fussteil des Nähfusses ist an einem Halter 1 mit.
Hilfe der Gelenke 2 angelenkt. Die Nadeldurchtrittsöffnung ist mit 11 be- zeiehnet. In ihre Wandung münden mit. sich diametral gegenüberliegenden Öffnungen Ka näle 12 und 13, wobei der Kanal 12 durch einen Querkanal 14 mit zwei seitlichen Ka nälen 15 in Verbindung steht. Die Längs kanäle 13 und 15 gehen von je einer Einführ- öffnung aus, welche Öffnungen in einem ge meinsamen Anschlussstutzen 16a, z. B. für einen Schlauch, vorgesehen sind.
Nach den Fig. 1-3 ist es möglich, da.ss die Ka.nä@le @d reh Ansbohren des Nähfusses 10 erzeugt werden, wobei zweckmässigerweise durch Verschlusszapfen 16 die sich ergeben den unerwünschten Öffnungen verschlossen werden.
Bei der in Fig. 4 gezeichneten Variante ist der Nähfuss 10 aus giessbarem Material ge fertigt und die Kanäle sind als Rohrsystem eingegossen. Es kann auch zweckmässig sein, dass der Nähfuss aus durchsichtigem Material hergestellt ist, z. B. aus giessbarem. Kunstglas.
Einderartiger Nähfuss ermöglicht die Zu führung von Kühlluft auf die Nähnadel oder auch die Zuführung von flüssigen Substanzen zur Nähstele, was beim Nähen von gewissen Materialien, beispielsweise Leder oder thermo plastische Folien, sehr vorteilhaft sein kann.
Presser foot for sewing machines The present invention relates to a presser foot for sewing machines -and it enables the supply of cooling air or liquids to the sewing point and to the needle by providing according to the invention that the presser foot has channels through which before operation liquid or gaseous substances in: the needle passage opening can be promoted.
Two exemplary embodiments of the subject matter of the invention are shown in the drawing. They show: FIG. 1 a plan view of the partially stringed sewing foot.
FIG. 2 shows a longitudinal section along line 11-II from FIG. 1, FIG. 3 shows a cross-section along line III-III from FIG. 2, FIG. 4 shows the outline of a variant. The foot part of the presser foot is on a holder 1 with.
Help of the joints 2 articulated. The needle passage opening is denoted by 11. Open into their walls. diametrically opposite openings Ka channels 12 and 13, the channel 12 through a transverse channel 14 with two lateral Ka channels 15 is in communication. The longitudinal channels 13 and 15 each start from an insertion opening, which openings in a common connection piece 16a, z. B. for a hose are provided.
According to FIGS. 1-3 it is possible that the Ka.nä@le @d Reh drilling of the presser foot 10 are generated, the undesired openings being expediently closed by locking pins 16 that result.
In the variant shown in Fig. 4, the presser foot 10 is made of castable material and the channels are cast as a pipe system. It can also be useful that the presser foot is made of transparent material, e.g. B. from castable. Art glass.
Such a presser foot enables the supply of cooling air to the sewing needle or the supply of liquid substances to the sewing stele, which can be very advantageous when sewing certain materials, such as leather or thermoplastic films.
