Abstract

In order to ensure that the thread is drawn off without tension, the needle thread spool fitted on a central sleeve (1) is inserted into an outer sleeve (2) and axially uniformly pressed from both faces by piston rams (3) with the application of heat. This fully stress-relieves the needle thread spool (4) so that neither the material nor the seam is prestressed. Thus undesired tension curling phenomena can no longer occur. The new stress-relieved needle thread spool is particularly useful in connection with an unsupported lower thread spool running from the inside. In a further feature of the invention, the central sleeve, the outer sleeve and the piston rams can be heated and the central sleeve is made of an undeformable material. The spool support used to accept the needle thread spool is made in two parts.

Description

Verfahren und Vorrichtung zur Herstellung einer trägerlosen Nadelfadenspule und Spulen' träger zur Aufnahme einer Nadelfadenspule Method and device for producing a strapless needle thread bobbin and bobbins for receiving a needle thread bobbin
Die Erfindung betrifft ein Verfahren und eine Vorriclv tung zur Herstellung einer trägerlosen, von der Innen, seite ablaufenden Nadelfadenspule und einen Spulen¬ träger zur Aufnahme einer Nadelfadenspule.The invention relates to a method and Vorriclv processing for preparing an unsupported, from the inner, side running needle thread spool and a Spulen¬ carrier for receiving a needle thread coil.
Nadelfadenspulen werden grundsätzlich auf einem inneren Kern aufgepult, wobei der Fadenanfang am Kern festge¬ legt ist, beispielsweise durch Einklemmung in einem Schlitz. Da der Nadelfaden unter Vorspannung auf den Kern aufgebracht worden ist ( ech. bed. Auslängen), erfolgt die Entnahme ebenfalls unter Vorspannung. Diese Nadelfadenvorspannung wirkt sich negativ auf die Her¬ stellung bzw. das Aussehen der Nähte aus, insbesondere bei leichten Stoffen. Der Faden ist bemüht, seine ursprüngliche Ausgangslage einzunehmen und zieht sich dabei nach dem Vernähen wieder zusammen, wobei der Stoff mitgenommen wird. Dadurch tritt das bekannte Kräuseln des Stoffes ein. Durch überspulungen, einge¬ klemmte Fäden u. ä. kann ein ruckweiser Abzug eintre- ten, wodurch teilweise erhebliche Nahtunregelmäßigkei¬ ten entstehen. Der Erfindung liegt die Aufgabe zugrunde, eine Nadelfa¬ denspule so herzustellen, daß der Faden spannungslos abgezogen werden kann und beim Vernähen des Fadens keine Spannung auf den Stoff übertragen und auch bei leichten Stoffen ein Spannungskräuseln vermieden wird. Außerdem soll die fertige Nadelfadenspule vor Beschädigungen und Verschmutzungen geschützt werden.Needle thread bobbins are generally wound up on an inner core, the beginning of the thread being fixed on the core, for example by being clamped in a slot. Since the needle thread has been applied to the core under pre-tension (ech. Bed. Lengthening), the removal is also under pre-tension. This needle thread pretension has a negative effect on the manufacture or the appearance of the seams, in particular in the case of light fabrics. The thread tries to return to its original starting position and contracts again after sewing, taking the fabric with it. This leads to the familiar curling of the fabric. By spooling, jammed threads u. A jerky deduction can occur, which sometimes results in considerable seam irregularities. The invention is based on the object of producing a needle thread bobbin in such a way that the thread can be pulled off without tension and when the thread is sewn no tension is transferred to the fabric and tension curling is avoided even with light fabrics. In addition, the finished needle thread spool is to be protected against damage and soiling.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die auf eine Kernhülse aufgebrachte Nadelfadenspule in eine Außenhülse eingeschoben und von beiden Stirnseiten aus unter Wärmeeinwirkung durch Druckstempel gleichmäßig axial zusammengepreßt wird. Nach Beendigung des Preßvor¬ gangs werden erfindungsgemäß die Kernhülse und die zusam- mengepreßte Nadelfadenspule zusammen als Einheit aus der Außenhülse herausgezogen und anschließend die Nadelfaden¬ spule von der Kernhülse abgezogen. Vorteilhafterweise sind die Kernhülse, die Außenhülse und die Druckstempel beheizbar ausgebildet, wobei die Kernhülse zweckmäßiger- weise aus einem nichtverformbaren Material gebildet ist.This object is achieved in that the needle thread spool applied to a core sleeve is inserted into an outer sleeve and axially compressed from both end faces under the action of heat by means of pressure stamps. After completion of the pressing process, the core sleeve and the compressed needle thread bobbin are pulled out of the outer sleeve together as a unit and the needle thread bobbin is then pulled off the core sleeve. The core sleeve, the outer sleeve and the pressure stamps are advantageously designed to be heatable, the core sleeve advantageously being formed from a non-deformable material.
In Ausgestaltung der Erfindung .ist die fertige Nadelfaden¬ spule in einem aus einem Spulenträgerunterteil und einem darauf aufsetzbaren Spulenträgeroberteil bestehenden Spulenträger gelagert. Zum Aufstecken des Spulenträgers auf herkömmliche Garnständer ist zweckmäßigerweise auf der Außenseite des Spulenträgeruntertei ls eine Aufsteck¬ hülse angeordnet. Bei einer bevorzugten Ausführung ist der Spulenträgeroberteil aus Klarsichtmaterial gebildet. Auf der Stirnseite des Spulenträgeroberteils ist ein mittiger Fadenaustritt vorgesehen, der vorteilhafterweise durch eine polierte Öse gebildet ist.In an embodiment of the invention, the finished needle thread bobbin is mounted in a bobbin consisting of a lower bobbin part and an upper bobbin part that can be placed thereon. A plug-on sleeve is expediently arranged on the outside of the bobbin lower part for the purpose of plugging the bobbin onto conventional yarn stands. In a preferred embodiment, the upper part of the coil carrier is formed from transparent material. On the front of the upper part of the coil carrier is a provided central thread exit, which is advantageously formed by a polished eyelet.
Durch die Erfindung ist der Faden der Nadelfadenspule vollständig entspannt, so daß auch keine Vorspannung mehr in den Stoff bzw. in die Naht eingebracht wird und da¬ durch das Spannungskräuseln nicht auftreten kann. Beson¬ ders vorteilhaft ist die Verwendung von Nadelfadenspulen nach der Erfindung in Verbindung mit von innen ablaufen¬ den Unterfadenspulen. Der Innenabzug des Fadens schaltet störende Einflüsse durch eingeklemmte Fäden, überspulun- gen u. ä. aus. Da durch die Kernhülse ein entsprechend großer innerer Freiraum geschaffen ist, ist der Fadenab¬ lauf durchgehend leichter, gleichmäßiger und ruckfrei.By means of the invention, the thread of the needle thread bobbin is completely relaxed, so that no more pretension is introduced into the fabric or into the seam and, as a result, tension crimping cannot occur. It is particularly advantageous to use needle thread bobbins according to the invention in connection with bobbin threads running from the inside. The inner pull-off of the thread switches disruptive influences due to jammed threads, spools and the like. Ä. from. Since a correspondingly large inner free space is created by the core sleeve, the thread run is continuously lighter, more uniform and jerk-free.
Ein Ausführungsbeispiel der Erfindung ist in der Zeich¬ nung dargestellt und wird nachfolgend näher erläutert. Es zeigen:An embodiment of the invention is shown in the drawing and is explained in more detail below. Show it:

Fig. 2 einen Schnitt durch einen Spulenträger mit eingesetzter Nadelfadenspule.Fig. 2 shows a section through a bobbin with inserted needle thread bobbin.
Die auf eine Kernhülse 1 aufgebrachte Nadelfadenspule 4 wird in eine Außenhülse 2 eingesetzt und von beiden Stirnseiten aus durch innerhalb der Außenhülse 2 geführte Druckstempel 3 axial zusammengepreßt. Dabei sind die Kernhülse 1, die Außenhülse 2 und der Druckstempel 3 beheizbar ausgebildet. Nach Beendigung des Preßvorgangs werden der zusammengepreßte Nadelfadenwickel 4 und die Kernhülse 1 als Einheit aus der Außenhülse 2 herausgezo¬ gen. Anschließend wird die Nadelfadenspule 4 von der Kernhülse 1 abgezogen. Durch das Zusammenpressen der Nadelfadeπspule 4 erfolgt eine Verfestigung verbunden mit der Erzielung einer selbsttragenden Formstabilität. Außerdem wird die im Faden vorhandene Spannung abgebaut. Der Faden kann von der Innenseite der Nadelfadenspule 4 spannungsfrei abgezogen werden. Beim Zusammenpressen tritt weder eine Vergrößerung des Außendurchmessers, noch eine Verringerung des innerhalb der Nadelfadenspule 4 vorhandenen zylindrischen Hohlraumes ein. Es besteht die Möglichkeit, bei den üblichen Nadelfadenspulen 4 den vorhandenen Kern zu entfernen und durch eine nichtver- formbare Kernhülse 1 zu ersetzen. Der Nadelfaden kann aber auch sofort auf eine nichtverformbare Kernhülse 1 aufgespult werden. Die nichtverformbare Kernhülse 1 wird nach dem Abziehen der zusammengepreßten Nadelfadenspule 4 wieder zum Aufspulen verwendet und weist zweckmäßiger¬ weise einen Durchmesser auf, der dem Durchmesser der Hülse der bekannten Nadelfadenspule entspricht.The needle thread spool 4 applied to a core sleeve 1 is inserted into an outer sleeve 2 and axially compressed from both end faces by pressure rams 3 guided inside the outer sleeve 2. The core sleeve 1, the outer sleeve 2 and the pressure stamp 3 trained heatable. After completion of the pressing process, the compressed needle thread winding 4 and the core sleeve 1 are pulled out of the outer sleeve 2 as a unit. The needle thread spool 4 is then pulled off the core sleeve 1. By compressing the needle thread coil 4, solidification takes place, with the achievement of a self-supporting dimensional stability. In addition, the tension in the thread is reduced. The thread can be pulled off the inside of the needle thread spool 4 without tension. When pressed together, there is neither an increase in the outside diameter, nor a decrease in the cylindrical cavity present within the needle thread spool 4. It is possible to remove the existing core in the conventional needle thread spools 4 and to replace it with a non-deformable core sleeve 1. The needle thread can also be wound up immediately on a non-deformable core sleeve 1. After the compressed needle thread spool 4 has been pulled off, the non-deformable core sleeve 1 is used again for winding and expediently has a diameter which corresponds to the diameter of the sleeve of the known needle thread spool.
Wie aus Fig. 2 erkennbar, besteht der Spulenträger aus einem Spulenträgerunterteil 5 und einem darauf absetz¬ baren Spulenträgeroberteil 7, die beide aus Klarsichtma¬ terial gebildet sind. Auf der Außenseite des Spulenträ- gerunterteils 5 ist eine zum Einsetzen auf bekannte Garnständer ausgebildete Aufsteckhülse 6 angeordnet. Der ablaufende Faden 9 wird zentrisch aus der oberen Stirn- seite abgezogen. Zur Führung dient eine polierte Öse 8. Durch den Spulenträger 5; 7 wird die Nadelfa¬ denspule 4 vor Verschmutzungen, Verformungen u. ä. geschützt. Der durchsichtige Spulenträgeroberteil 7 ermöglicht die Kontrolle über den Stand des Fadenab¬ zugs. As can be seen from FIG. 2, the bobbin consists of a lower bobbin part 5 and a bobbin upper part 7 which can be placed thereon, both of which are formed from transparent material. On the outside of the lower bobbin 5 there is a push-on sleeve 6 designed for insertion on known yarn stands. The running thread 9 is centrically from the upper end side deducted. A polished eyelet 8 is used for guidance. 7, the needle thread bobbin 4 is protected against dirt, deformation and the like. protected. The transparent bobbin upper part 7 enables control over the state of the thread draw.
