Die Zeichnungen beschränken sich zwecks besserer Übersichtlichkeit auf die notwendigsten Teile der Nähmaschine, in die die erfindungsgemäße Schneideinrichtung eingebaut ist.For better clarity, the drawings are limited to the most necessary parts of the sewing machine in which the cutting device according to the invention is installed.

Mit der Bezugszahl 1 wird eine Zweinadelnähmaschine üblicher Konstruktion bezeichnet, deren auf- und abbewegte Nadelstange 2 einen Nadelhalter mit zwei Nadeln aufweist, von denen nur eine Nadel 3 (Fig. 1) sichtbar ist. Fig. 2 zeigt die Stichplatte 4 mit den Stichlöchern 5 und 5 für die erwähnten beiden Nadeln, die mit unterhalb der Stichplatte 4 angeordneten, nicht dargestellten Doppelsteppstich-Greifern in bekannter Weise die beiden Nähte für die Herstellung eines paspelierten Tascheneingriffes nähen. Zwischen den beiden Nadeln bewegt sich ein Trennmesser 6 bekannter Bauart zur Erzeugung des Längsschlitzes L für die Taschenöffnung. Die Stichplatte 4 ist in einer Ausnehmung der Grundplatte 7 der Nähmaschine 1 befestigt, die ihrerseits in eine übliche Nähtischplatte 12 eingelassen ist. Die Stichplatte 4 hat zwei Öffnungen für den Durchtritt der Zähne eines üblichen zweireihigen hüpfenden Transporteurs 8 und die Grundplatte 7 ist mit einer Öffnung 9 für den Durchlaß der Winkelschneidmesser 10 und 11 der Schneidvorrichtung versehen, die in der Fig. 1 in ihrer Ausgangsstellung dargestellt ist. Die Winkelschneidmesser 10 und 11 bestehen aus vier dolchartigen Schneidklingen, die zusammen nur in Fig. 2 sichtbar sind und um einen unten noch näher beschriebenen Führungsdorn 13 angeordnet sind. Die jeweils paarweise um 450 zueinander angestellten Schneidklingen bilden die beiden Winkelschneidmesser 10 und 11, die durch einen einfachwirkenden Druckluftzylinder 14 gemeinsam aus der in Fig. 1 gezeigten Ausgangsstellung in die höhergelegene Schneidstellung bewegt werden, wobei sie die Öffnung 9 in der Grundplatte 7 durchfahren und die Einzwickschnitte E1 und E2 nacheinander ausführen.Reference number 1 denotes a two-needle sewing machine of conventional construction, the up and down moving needle bar 2 of which has a needle holder with two needles, of which only one needle 3 (FIG. 1) is visible. Fig. 2 shows the stitch plate 4 with the stitch holes 5 and 5 for the two needles mentioned, which sew the two seams for the production of a piped pocket opening in a known manner with double lockstitch looper arranged below the stitch plate 4. A separating knife 6 of known design moves between the two needles to produce the longitudinal slot L for the pocket opening. The stitch plate 4 is fastened in a recess in the base plate 7 of the sewing machine 1, which in turn is embedded in a conventional sewing table plate 12. The throat plate 4 has two openings for the passage of the teeth of a conventional double-row hopping conveyor 8 and the base plate 7 is provided with an opening 9 for the passage of the angle cutting blades 10 and 11 of the cutting device, which is shown in Fig. 1 in its initial position. The angle cutting blades 10 and 11 consist of four dagger-like cutting blades, which together are only visible in FIG. 2 and are arranged around a guide mandrel 13, which is described in more detail below. The pair of cutting blades positioned at 45 ° to each other form the two angle cutting blades 10 and 11, which are moved together by a single-acting pneumatic cylinder 14 from the starting position shown in FIG. 1 to the higher cutting position, passing through the opening 9 in the base plate 7 and make the incisions E1 and E2 one after the other.

Zu diesem Zweck sind die Winkelschneidmesser 10 und 11 vertikal verschiebbar gelagert, damit sie von der ausfahrenden Kolbenstange 14' des Druckluftzylinders 14 bewegt werden können. Die vier Schneidklingen der Winkelschneidmesser 10 und 11 sind in bekannter Weise mittels der Klemmschrauben 15 und 15' und entsprechend geformten Klemmstücken auf dem Messerkopf 16 auswechselbar fixiert, welcher mit der Kolbenstange 14' des Druckluftzylinders 14 fest verbunden ist. Die Kolbenstange 14' wird durch die stationäre Führungsplatte 17 hindurchgeführt, welche an einem feststehenden Teil der Nähmaschine 1 befestigt ist. Die Führungsplatte 17 ist über eine parallel zur Kolbenstange 14' angebrachte, nach unten gerichtete Tragstange 18 mit einem Halter 19 für den Druckluftzylinder 14 verbunden. Längs der Stange 18 wird ein Klemmstück 20 geführt, welches einenends an der Kolbenstange 14' festgeklemmt ist und deren Auf- und Abbewegungen mitmacht; anderenends umfaßt das Klemmstück 20 gabelförmig auslaufend die Tragstange 18. An Aufnahmelöchern des Klemmstückes 20 sowie eines Haltebleches 21 am unteren Ende des Druckluftzylinders 14 sind die Enden einer Rückholfeder 22 eingehängt, die die ausgefahrene Kolbenstange 14' in die Ausgangsstellung (Fig. 1) zurückzieht, sobald der Druckluftzylinder 14 nicht mehr mit Druckluft beaufschlagt wird. Der Druckluftzylinder 14 kann über den Druckluftanschluß 2 3 mit Druckluft beaufschlagt werden, die von einer nicht gezeigten Druckluftquelle kommt: Nachdem der in bekannter Weise nähgerecht vorbereitete Paspelstreifen - zusammen mit oder auch ohne einem Taschenpattenzuschnitt - auf den mit einer Tasche zu versehenen Hauptstoff positioniert worden ist, kann das Nähen der Nähte N1 und N2 (Fig. 3, oben) begonnen werden, wobei das Trennmesser 6 für den Längsschnitt L der Taschenöffnung an vorgegebener Stelle zugeschaltet wird. Wenn das hierbei in Pfeilrichtung NV transportierte Nähgut in den Bereich der Schneidvorrichtung gekommen ist, kann die Anbringung des ersten Einzwickschnittes E1 mittels des Winkelschneidmessers 10 an vorbestimmter Stelle erfolgen. Solche Einzwickschnitte oder Winkelschnitte verbinden bekanntlich den Längsschlitz L der Taschenöffnung mit den Nahtenden; Einzwickschnitt E1 stellt die Verbindung zwischen L und den b eiden in Nähgutvorschubrichtung NV vorderen Enden der Nahtabschnitte N1 und N2 (Fig. 3, oben) her. Selbstverständlich werden die jeweiligen Enden der Nähte durch nicht gezeigte, bekannte Nahtverriegelungen gesichert. Der Führungsdorn 13 verhindert beim Schneidvorgang ein unerwünschtes Einschneiden des Winkelschneidmessers 10 in den Patten- und/oder Hauptstoff, indem er dieselben abweisend beiseitedrängt. Der Führungsdorn 13 verhindert weiterhin durch seine Abweisfunktion ein ebenfalls nicht erwünschtes Einschneiden des gleichzeitig ausgefahrenen, aber jetzt nicht benötigten Winkelschneidmessers 11, indem der Stoff, der sich auf der Seite der Schneidvorrichtung im Wirkungsbereich des Winkelschneidmessers 11 befindet, beiseitegedrängt wird.For this purpose, the angle cutting knives 10 and 11 are vertically displaceably mounted so that they can be moved by the extending piston rod 14 'of the compressed air cylinder 14. The four cutting blades of the angle cutting blades 10 and 11 are fixed in a known manner by means of the clamping screws 15 and 15 'and correspondingly shaped clamping pieces on the cutter head 16, which is firmly connected to the piston rod 14' of the compressed air cylinder 14. The piston rod 14 'is passed through the stationary guide plate 17 which is attached to a fixed part of the sewing machine 1. The guide plate 17 is connected to a holder 19 for the compressed air cylinder 14 via a support rod 18, which is attached parallel to the piston rod 14 ′ and is directed downward. Along the rod 18, a clamping piece 20 is guided, which is clamped at one end to the piston rod 14 'and takes part in its up and down movements; at the other end, the clamping piece 20 includes the support rod 18, which ends in a fork-shaped manner. Receiving holes in the clamping piece 20 and a holding plate 21 at the lower end of the compressed air cylinder 14 hang the ends of a return spring 22 which pulls the extended piston rod 14 'back into the starting position (FIG. 1), as soon as the compressed air cylinder 14 is no longer subjected to compressed air. The compressed air cylinder 14 can be supplied with compressed air via the compressed air connection 2 3, which comes from a compressed air source, not shown: After the piping strip, which has been prepared in a known manner for sewing, has been positioned - together with or without a pocket flap cut - on the main fabric to be provided with a pocket, the sewing of the seams N1 and N2 (FIG. 3, top) can be started, with the separating knife 6 is switched on for the longitudinal section L of the pocket opening at a predetermined point. If the sewing material transported in the direction of the arrow NV has come into the area of the cutting device, the first gusset cut E1 can be made at a predetermined point using the angle cutting knife 10. Such gusset cuts or angular cuts are known to connect the longitudinal slot L of the pocket opening with the seam ends; Wrapping cut E1 establishes the connection between L and the two front ends of the seam sections N1 and N2 in the material feed direction NV (FIG. 3, top). Of course, the respective ends of the seams are secured by known seam locks, not shown. The guide mandrel 13 prevents an unwanted cutting of the angle cutting knife 10 into the flap and / or main material during the cutting process by repulsively pushing it aside. The guide mandrel 13 further prevents, by means of its rejection function, also undesired cutting of the simultaneously extended, but now not required, angle cutting knife 11, by pushing aside the material which is on the side of the cutting device in the area of action of the angle cutting knife 11.

In Fig. 3 ist das für den jeweiligen Einzwickschnitt nicht benötigte Winkelschneidmesser strichpunktiert angedeutet. So wird in Fig. 3 oben das Messer 11 beim Einzwickschnitt E1 und in Fig. 3 unten das Messer 10 beim Einzwickschnitt E2 als nicht benötigt gezeigt. Nach erfolgtem Weitertransport des Nähgutes wird an vorbestimmter Stelle der 2. Einzwickschnitt durch das Winkelschneidmesser 11 angebracht, wobei nunmehr ein nicht erwünschter Einschnitt des Messers 10 durch den Führungsdorn 13 auf der jetzt den Nadeln abgewandten Seite der Schneidvorrichtung sinngemäß in gleicher Weise wie zuvor beschrieben, verhindert wird. Im Schneidbereich sind nicht gezeigte Stoffniederhalter vorgesehen.In Fig. 3, the angle cutting knife not required for the respective wound cut is indicated by dash-dotted lines. Thus, in FIG. 3 the knife 11 at the wrapping cut E1 and in FIG. 3 below the knife 10 at the wrapping cut E2 is shown as not required. After the further transport of the sewing material has been carried out, the second incision is made at a predetermined point by the angle cutting knife 11, an undesired incision of the knife 10 by the guide mandrel 13 on the side of the cutting device now facing away from the needles being prevented in the same manner as previously described becomes. In the cutting area, fabric retainers, not shown, are provided.

Der zeitliche Ablauf der einzelnen, zur Herstellung einer paspelierten Taschenöffnung benötigten Arbeitsschritte des Nähens und Schneidens wird mit den bekannten Mitteln der Steuerungstechnik bewirkt. Die erfindungsgemäße, besonders einfach angetriebene Schneidvorrichtung für die Einzwickschnitte hat den Vorzug, an viele Variationen des Arbeitsablaufes anpaßbar zu sein.The chronological sequence of the individual sewing and cutting work steps required to produce a piped pocket opening is effected with the known means of control technology. The cutting device according to the invention, which is driven in a particularly simple manner, for the gusset cuts has the advantage of being adaptable to many variations of the workflow.
