KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei Flaschenhülsen - Nähmaschinen, deren Nähte als Kettenstiche hergestellt werden, war bisher für die Bildung dieser Kettenstiche eine bewegliche Führung des Nähfadens im Cylinder nöthig, deren Bewegung von der des Nadelrahmens abgeleitet wurde, und welche dafür sorgte, dafs die Nadel den Faden immer richtig fassen konnte. Bei der vorliegenden Nadel ist diese bewegliche Führung vollständig entbehrlich, indem diese Nadel derartig beschaffen ist, dafs das Eingreifen des Fadens, der im Cylinder durch ein festes Führungsöhr geht und von da durch das Stichloch frei heraushängt, stets gesichert ist.With bottle sleeves - sewing machines, the seams of which are made as chain stitches, was So far, a movable guide of the sewing thread in the cylinder for the formation of these chain stitches necessary whose movement was derived from that of the needle frame, and which for it made sure that the needle could always grasp the thread correctly. With the present needle is this movable guide can be completely dispensed with in that this needle is designed in such a way that that the thread, which passes through a fixed guide eye in the cylinder and from there, engages as it hangs out freely through the needle hole, it is always secured.

Der Faden wird von dem vorrückenden Stroh (Fig. 1) in eine in der Transportrichtung des Strohes geneigte Lage gebracht. Die Nadel welche in Fig. 6 und 7 in je drei Ansichten in gröfserem Mafsstab unter Weglassung des Kläppchens dargestellt ist, hat gegen Cylinder und Transporteur die in Fig. 1 und 2 gezeichnete Stellung. Sie hat einen (in der Ansicht Fig. 2) schräg nach links gebogenen Haken, dessen Abbiegung (welche an sich bekannt ist, nämlich 'bei anderen Maschinen in anderer Weise verwendet) bewirkt, dafs der Faden an der Stelle wo er durch das Führungsöhr kommt, beim Abwärtsgehen der Nadel sicher gefafst wird (Fig. 3), während beim Aufwärtsgehen die Nadel mit ihrer Spitze stets rechts vom F'aden heraufkommt. Die Nadel ist ferner im Hakeninnern nach Art einer Schraubenfläche derart ausgebildet, dafs die beim Abwärtsgehen sich bildende Fadenschlinge, deren Ebene zuerst in der Transportrichtung des Strohes steht (Fig. 4), sich um 90 ° dreht und dann senkrecht zur Transportrichtung des Strohes steht (Fig. 5), so dafs beim Transportiren die Schlinge um den Nadelhals zu liegen kommt (Fig. 7) und so niemals von der Nadel fallen gelassen werden kann, wie dies der Fall (ersichtlich aus Fig. 8), wenn man etwa eine bisherige Nadel mit ihrem geraden Haken senkrecht oder schräg zur Transportrichtung des Strohes stellen wollte, um den Faden am Führungsöhr fassen zu können.The thread is from the advancing straw (Fig. 1) in one in the transport direction brought to the inclined position of the straw. The needle which is shown in Fig. 6 and 7 in three views in is shown on a larger scale with the omission of the flap, has against cylinder and The conveyor position shown in FIGS. 1 and 2. It has a (in the view of Fig. 2) hook bent obliquely to the left, the bend of which (which is known per se, viz Used in a different way on other machines) causes the thread to stay in place where it comes through the guide eye, is securely grasped when the needle goes down (Fig. 3), while when going up the needle always comes up with its point to the right of the thread. The needle is also designed in the inside of the hook in the manner of a screw surface in such a way that that the thread loop that forms when going down, its plane first in the direction of transport of the straw is (Fig. 4), rotates 90 ° and then perpendicular to the transport direction of the straw stands (Fig. 5), so that the noose around the neck of the needle when it is being transported comes to rest (Fig. 7) and so can never be dropped from the needle, as this is the case (shown in FIG. 8) if one uses a previous needle with its straight one Wanted to place the hook perpendicular or at an angle to the transport direction of the straw, around the To be able to grasp the thread at the guide eye.

Claims (1)

Patent-Anspruch:Patent claim: Eine Nadel für Flaschenhülsen-Maschinen, welche die Bildung der Kettenstiche ohne bewegliche Führung des Fadens im Cylinder dadurch gestattet, dafs der schräge Haken, welcher senkrecht zur Transportrichtung des Strohes abgebogen ist, mit einer Schraubenfläche in seinem Inneren versehen ist, um die Fadenschlinge in eine Ebene senkrecht zur Transportrichtung des Strohes zu bringen, so dafs sie beim Aufwärtsgehen der Nadel und Transportiren des Strohes über den Nadelhals gelangen mufs und nicht etwa über den Haken abstreift.A needle for bottle sleeve machines that allows the formation of chain stitches without moving Guiding of the thread in the cylinder is made possible by the fact that the inclined hook, which is bent perpendicular to the transport direction of the straw, with a screw surface in its interior is provided to the thread loop in a plane perpendicular to the transport direction of the straw, so that they move the needle and transport it upwards of the straw must get over the needle neck and not slip over the hook.
