Description
Mit Doppelsteppstichnaht maschinengenähter Selbstbinder und Verfahren zur Herstellung der Doppelsteppstichnaht Beim Binden von Selbstbindern werden diese erheblichen Beanspruchungen auf Zug ausgesetzt. Hierbei tritt aber eine Zerstörung der auf der Rückseite der Krawatte verlaufenden Naht ein, weil zwar der Stoff auf Zug hin nachgibt, die Naht hingegen nicht und somit reißt.Machine-sewn self-tie and process with lockstitch seam for the production of the lockstitch seam When tying self-ties, these are exposed to considerable stresses on train. Here, however, a destruction occurs the seam running on the back of the tie, because the fabric is on Tensile yields, but the seam does not and therefore tears.
:Ulan hat bereits versucht, diesen Nachteil dadurch zu beseitigen, daß man die Naht von Hand mit sehr losen Stichen näht. Die Herstellung von maschinengenähten Bindern mit einer reißsicheren, elastischen Naht ist bisher nicht möglich gewesen. In der Schaffung dieser Möglichkeit beruht die Erfindung.: Ulan has already tried to eliminate this disadvantage by that the seam is sewn by hand with very loose stitches. The manufacture of machine-sewn Ties with a tear-proof, elastic seam has not been possible until now. The invention resides in creating this possibility.
Dieselbe sieht eine maschinengenähte Doppelsteppstichnaht, bestehend aus Ober- und Unterfaden, vor, von denen mindestens einer länger ist als die freie Länge der Naht. Besonders zweckmäßig ist es, den Unterfaden länger zu wählen als die an sich für die Naht zur Verfügung stehende freie Länge des Stoffes. Es ergibt sich dann eine Nahtform, bei welcher der Unterfaden lose zwischen je zwei Stichen des Oberfadens liegt. Wird der Binder auf Zug beansprucht, so zieht sich der Unterfaden stramm. Die Herstellung solcher Nähme kann auf Nähmaschinen üblicher Art erfolgen. Es ist nur erforderlich, daß die übliche Spannung des aus dem Schiffchen oder Greifer austretenden Fadens aufgehoben, zum mindesten aber auf ein ganz geringes Maß beschränkt wird. Um beim Nähvorgang ein Hineinziehen des losen Unterfadens in den Stoff zu vermeiden, empfiehlt es sich, für ihn etwas stärkeres Garn zu verwenden als für den Oberfaden.The same sees a machine-sewn lockstitch seam, consisting of upper and lower thread, at least one of which is longer than the free one Length of the seam. It is particularly useful to choose the bobbin thread longer than the free length of the fabric available per se for the seam. It results then a seam shape in which the bobbin thread loosely between each two stitches of the upper thread. If the tie is put under tension, the bobbin thread pulls tight. The production of such sewing can be done on sewing machines of the usual type. It is only necessary that the usual tension of the boat or gripper exiting thread canceled, but at least limited to a very small amount will. To prevent the loose bobbin thread from being drawn into the fabric during the sewing process avoid, it is advisable to use slightly thicker thread for him than for the upper thread.
Der gemäß vorstehendenAusführungenausgebildete Selbstbinder läßt sich genau so billig herstellen wie die bisher üblichen maschinengenähten Binder, weist ihnen gegenüber jedoch den Vorteil auf, daß er in der Längsrichtung auf Zug beansprucht werden kann, ohne daß irgendwelche Beschädigungen der Naht auftreten.The self-tie formed according to the above embodiments can be Manufacture just as cheaply as the previously common machine-sewn binders, shows however, they have the advantage that it is subject to train in the longitudinal direction without causing any damage to the seam.
