Description
Verfahren zur Erzeugung einer Pseudo-Doppelsteppstichnaht Es ist ein Verfahren zur Erzeugung einer Zwei fa & nheftnaht bekanntgoworden, bei welcher der Charakter einer Doppelsteppstichnaht, (d. h. das Zu- sammenhalten von Gewebelagen mit einem O.b.erfa- den und einem Unterfaden und deren Verbindung innerhalb der Stofflagen, im wesentlichen erhalten bleibt. Der Unterschied zwischen der normalen Dop pelsteppstichnaht und der nach dem bekanntgewor denen Verfahren erzeugten Zweifadenheftnaht be- steht,darin, dass :bei der normalen .Naht der Oberfaden mit dem Unterfaden innerhalb der Stofflagen ver schlungen wird, bei der Zweifadenheftnaht die Ver bindung des Oberfadens mit dem Unterfaden inner halb der Stofflagen mit Kunststoff, insbesondere ther moplastischem Kunststoff erfolgt. Bei der bekannten Zweifadenheftnaht werden ,die beiden Fäden in aufesnanderfolgenden Abständen ohne gegensaitige Verschlingung durch Verklebung, Verzahnung oder idergleichen mittels thermoplasti- scher Werkstoffe miteinander verbunden. Der Unter fadenvorrat kann dabei genau so gross sein wie der Oberfadenvorrat. Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Erzeugung einer Pseudo-Doppelstepp- stichnaht. Das erfindungsgemässe Verfahren ist da durch gekennzeichnet, d@ass die Verbindung d .es Ober fadens mit dem Unterfaden ausserhalb der .Gewebe lagen durch Hinzufügen einer verflüssigten Menge eines thermoplastischen Materials erfolgt und dass ,diese Verbindungsstelle alsdann in (das Nähgut einge zogen wird. Im nachfolgenden ist ein Mspiel des Verfahrens beschrieben und auf der beiliegenden Zeichnung ,eine zur Ausbildung desselben dienende Maschine dargestellt, und zeigen: Fig. leine fertige Nahtstelle sowie die erste Arbeitsphase der Nahtbildung bei nach abwärts gehen der Nähmaschinennadel mit idam Oberfaden, Fig. 2 eine weitere Arbeitsphase der Nahtbildung, bei,der ,die Nähmaschlnennadel den Oberfaden durch die Gewebelagen gebracht hat, Fig. 3 eine weitere Arbeitsphase .der Nahtbildung, bei der der Oberfaden( mit dem Unterfaden verbunden wird, Fig. 4 die letzte Arbeitsphase der Nahtbildung, bei der @die Verbindungsstelle zwischen Ober- und Unterfaden in die Gewebelagen eingezogen wird, Fig. 5 eine Draufsicht in Richtung auf die Ver- bindungsstelle zwischen Ober- und Unterfaden vor ,der Verbindung, Fig 6 :eine Ansicht in Richtung z. B. von oben auf,die Fig. 2. Wie bei einer normalen Nähmaschine bewegt sich die Nähmaschinennadel 1 (Fig. 1) auf- rund abwärts, und durch das Nadelöhr 2 ist der Oberfaden 3 eingefädelt. Die zu verbindenden Gewebelagen 4, 5 werden wäqderum wie ;bei der normalen Nähmaschine durch einen nicht besonders gezeichneten Stoffschie ber auf der nichtgezeichneten Stichplatte bew ,egt. Während der Ruhestellung des Stoffschiebers dringt die Nähmaschinennadel 1 (Fig. 2) in die Gewebelagen 4, 5 so tief ,ein, dass oder Oberfaden 3 eine Schlaufe 6 bildet, die ;ein Stück unter idie Unter- kante 7 (der Gewebelage 5 hervorragt. Die .Nähmaschinennadel 1 ist um einige Winkel- grade gedreht:(Fig. 6), so dass das Nadelöhr 2 um den Winkel zur Stoffvorschubrichtung steht und eine Tan gente : an die Schlaufe 6 ,des Oberfadens 3 und an die Nähmaschinennadel 1 eine Gerade A -B ergibt, die parallel zur Stoffvorschubrichtung verläuft. Der Unterfaden 8 äst auf der nicht gezeichneten Stich platte so geführt, dass er sich unter der Gewebelage 5 wie die Gerade A -B ,an die Nähmaschinennadel 1 und an die Schlinge 6 ;des Oberfadens 3 anlegt. Unter der Stichplatte und durch @diese hindurch bewegt sich ein düsenartiger Kolben 9 schräg auf und abwärts. Dieser düsenartige Kolben 9 äst vorn gespalten, so dass zwei Lippen 10, 11 vorhanden sind. Er enthält im Inneren, in der eigentlichen Düse 12 oder einer ähnlichen Zuführungsvorrichtung, ein schnellhärtendes Verbindungsmittel, etwa thermopla- stischen Kunststoff 13. Dieser thermoplastische Kunststoff 13 ist in :Form von Pulver, Granulat oder Draht in den düsenartigen Kolben 9 oder in eine ähnliche Zuführungsvorrichtung eingebracht worden. Mittels :elektrischer Heizung oder Heissluft oder hochfrequenten Stromes oder sonstwie wird der ther moplastische Stoff 13 (vorn) auf Schmelztemperatur gebracht, so dass dieser thermoplastische Stoff 13 beim Betrieb :der Maschine innerhalb der Lippen 10, 11 des düsenartigen Kolbens 9 stets einen flüssigen Zustand hat. In dem Augenblick des Nähvorganges, in Odem die Nähmaschinennadel 1 (Fig. 2) den Oberfaden 3 ,durch die Gewebelagen 4, 5 gebracht hat und der Oberfaden 3 eine Schleife 6 gebildet hat und der Un terfaden 7 an der Schleife 6 des Oberfadens 3 anliegt, geht der düsenartige Kolben 9 nach oben. Die Lippen 10, 11 des düsenartigen Kolbens 9 greifen gabel artig über die Verbindungsstelle 14 zwischen Ober- und Unterfaden 3, 8 (Fig. 5), und zwar so weit, bis (die Verbindungsstelle 14 in Iden flüssigen thermo plastischen Kunststoff 13, welcher sich zwischen den Lippen 10,11 des düsenartigen Kolbens 9 befindet, eintaucht. Der @düsenartwge Kolben 9 geht dann nach unten in seine Ausgangsstellung zurück und hat einen Tropfen 15 thermoplastischen Kunststoffes an der Verbindungsstelle 14 hinterlassen. Dieser Tropfen 15 erhärtet schnell und stellt damit die Verbindung zwischen Oberfaden 3 und Unterfaden 7 her. Im weiteren Verlauf ;des Nähvorganges geht die Nähmaschinennadel 1 wieder nach oben, der Ober faden 3 wind angezogen, und zwar so, dass die Ver bindungsstelle in die Gewebelagen 4, 5 eingezogen wird und unter der Gewab.elage 5 nicht mehr heraus ragt. Mit dieser letzten Phase ist eine Nahtstelle hergestellt, und der Nähvorgang :beginnt von vorn, wie oben beschrieben. Eine Reihe dieser Nahtstellen ergibt eine der normalen Doppelsteppstichnaht sehr ähnliche Zweifadenbefestigungsnaht.
