Description
In einem Arbeitsgang herzustellende Zusammennäh- und Überdecknaht Die durch das Patent 477 oii bekannte Naht ist, wie nachfolgend beschrieben, verbessert.Sewn and overlap seam to be produced in one operation The seam known from the 477oii patent is improved as described below.
Bei der bekannten Zusammennäh- und Überdecknaht ist die Zusammennähnaht mit Einfach-oder Doppelkettenstich genäht. Nach der Erfindung wird die Naht mit einer Überwendlich-Zusammennähnahtausgeführt, die in Anbetracht ihrer auch nur halb so großen Stichlänge gegenüber der Überdeck-Überwendlichnaht eine erheblich größere Dehnbarkeit als die bekannte Zusammennähnaht besitzt.In the known sewn-together and cover seam, the sewn-together seam is sewn with single or double chain stitch. According to the invention, the seam is with an overlock stitched seam, which in view of its only half Such a large stitch length compared to the overdeck overlock seam a considerably larger one Possesses extensibility than the well-known sewing seam.
Die Überwendlich-Zusammennähnaht wird von einem Nadel- und einem Deckfaden gebildet. Der Deckfaden wird vom oberen Nadeleinstich bis zum unteren Nadelaustritt um die Stoffkante gelegt und dort vom Nadelfaden gebunden.The overlock seam is made of a needle thread and a cover thread educated. The cover thread is from the upper needle entry to the lower needle exit placed around the edge of the fabric and tied there by the needle thread.
Fig. i zeigt in einer Seitenansicht die beiden Nähvorgänge der zweifachen Naht mit den Nähwerkzeugen ohne Vorschubvorrichtung und zeigt als innenseitiges Bild der Zusammennäh-und Überdecknaht die nur halb so langen Stichlängen der Zusammennäh-Überwendlichnaht im Verhältnis zu den Stichlängen der Überdeck-Überwendlichnaht.Fig. I shows a side view of the two sewing processes of the twofold Seam with the sewing tools without a feed device and shows as an inside Image of the sewing and overlapping seams the stitch lengths of the sewing overlock seam, which are only half as long in relation to the stitch lengths of the overdeck overlock seam.
Fig. 2 zeigt innenseitig die Überdeck-Überwendlichnaht ohne Zusammennähnaht mit dem An- bzw. Durchstich der Überdecknaht, deren Faden die Überdecknahtlinien links und rechts der Zusammennähnaht bilden, sowie den Ein-und Austritt des Nadelfadens durch die Zusammennäh-Überwendlich-Nahtrippe.Fig. 2 shows the inside of the overlap overlock seam without sewing together with the stitching or piercing of the overlap seam, the thread of which is the overlap seam lines to the left and right of the seam, as well as the entry and exit of the needle thread through the sewing overlock seam rib.
Fig. 3 zeigt die Zusammennäh- sowie Überdeck-Überwendlichnaht im Schnitt.Fig. 3 shows the sewing together and overdeck overlock seam in section.
Fig. 4 zeigt den Nähvorgang der Überdeck-Überwendlichnaht im Querschnitt mit der die Zusammennäh-Überwendlich-Nahtrippe, durchstechenden Überdecknadel und den Überdeckfaden führenden Greifer sowie die Überdeckzunge, die mittels ihrer Nute das Durchstechen der Zusammennäh-Überwendlich-Nahtrippe ermöglicht. Die beiden Stoffteile a und b werden in bekannter Weise unter den Drückerfuß c gebracht, von den Schermessern d und e beschnitten und der Nadel lt. zum Zusammennähen zugeführt (Fig. i).Fig. 4 shows the sewing process of the overlock seam in cross section with the sewing overlock seam rib, piercing cover needle and the cover thread leading gripper as well as the overlap tongue, which allows piercing of the sewing overlock seam rib by means of its groove. The two pieces of fabric a and b are brought under the presser foot c in a known manner, trimmed by the cutting knives d and e and fed to the needle for sewing (Fig. I).
Die Zusammennähnaht ist eine Überwendlichnaht und wird durch den Nadelfaden f und einen Deckfaden g gebildet. Beim Hochgehen der Nadel h tritt die Spitze des Greifers i durch die Schleife h des Nadelfadens f, der mit der Nadel lt hochgehende Greifer i, welcher den Deckfaden g führt, bietet denselben der abwärts gehenden Nadel k zum Anstechen dar. Der Deckfaden j wird vom oberen Nadeleinstich bis zum unteren Nadelaustritt um die Stoffkanten gelegt und dort vom Nadelfaden f gebunden.The sewn seam is an overlock seam and is formed by the needle thread f and a cover thread g. When the needle h goes up, the tip of the looper i passes through the loop h of the needle thread f, the looper i that goes up with the needle lt and guides the cover thread g, offers the same as the downward going needle k for piercing The upper needle entry is placed around the edges of the fabric as far as the lower needle exit and is tied there by the needle thread f.
Die Zusammennähnaht wird in demselben Arbeitsgang überdeckt. Die Überdecknaht wird von dem Nadelfaden 1, dem Überdeckfaden in, der Nadel n und dem Greifer o gebildet (Fig. i und 4).The sewn seam is covered in the same operation. The overlap seam is formed by the needle thread 1, the overlap thread in, the needle n and the looper o (Fig. I and 4).
Der Nähvorgang ist derselbe wie bei der Zusammennähnaht mit dem Unterschied, daß die Stichlänge der Zusammennähnaht nur halb so lang ist als die Stichlänge der Überdecknaht.The sewing process is the same as when sewing together with the difference that that the stitch length of the seam is only half as long as the stitch length of the Overlap seam.
Obwohl das Schermesser vor dem Zusammennähen schneidet, ist die Arbeitsweise dieselbe, wie im Hauptpatent beschrieben.Although the shear knife cuts before sewing, the way it works is the same as described in the main patent.
