Definitions
- the invention relates to a flat knitting machine with a front and a rear needle bed, which is composed of individual interchangeable sections.
- the invention has for its object to design a modern flat knitting machine so that it can work with needles of different fineness.
- the object is achieved with a flat knitting machine of the type mentioned at the outset in that the sections of the needle beds have a different needle pitch, so that needles of different fineness are used in adjacent needle bed sections.
- the needles of different fineness can be distributed in any way on the needle beds, depending on whether several individual knits are to be made and whether knits of different fineness should be distributed symmetrically or asymmetrically in these knitted fabrics.
- the interchangeable sections of the needle bed can have different lengths, so that areas of different widths of different fineness can be knitted.
- the individual lock systems can each be assigned needles of different fineness, and the machines can be switched and controlled in such a way that different lock systems also take over the work of stitch formation in the different sections .
- At least one of the several can be expedient Lock systems differ from the others by a differently designed mesh cap control curve.
- the carriage can have a knitting and neck lock system for needles of fineness 2-4, one for needles of fineness 3-5, one for needles of fineness 4-6 and one for needles of fineness 7 and 8.
- a knitting and neck lock system for needles of fineness 2-4, one for needles of fineness 3-5, one for needles of fineness 4-6 and one for needles of fineness 7 and 8.
- the use of different lock systems in different lengths of a needle bed presents no difficulties.
- the application of the invention to knitting machines in which a single drive is provided for each needle of each needle bed becomes even more problem-free.
- the schematic drawing shows the front needle bed 10 and the rear needle bed 11 of a flat knitting machine, both of which are composed of individual sections 10.1 and 11.1 of different lengths.
- the connection points between the individual sections 10.1 and 11.1 of the needle beds 10 and 11 are thick dash-dotted lines indicated.
- All of the needle bed sections 10.1 and 11.1 in the illustrated embodiment which are filled with needles are identified by numbers, 4, 6 or 8, which are the numbers of the fineness of the needles used there.
- Two separate shaped knitted parts 12 and 13 are to be produced on the flat knitting machine. For this reason, middle sections 10.2 and 11.2 are present in the needle beds, in which no needles are inserted, because these areas are not to be used for knitting.
- One knitted part 12 should have five areas of different mesh size, which are arranged symmetrically distributed on it.
- the two outer sections 12.1 and 12.5 are knitted with needles of fineness 4, the adjacent areas 12.2 and 12.4 with needles of fineness 6 and the middle area 12.3 with needles of fineness 8.
- in the other knitted fabric 13 two knitted areas of unequal size and asymmetrically arranged are provided, of which the smaller knitted area 13.1 is to be knitted with needles of gauge 8 and the larger knitted area 13.2 is to be knitted with needles of gauge 4.
- the same needle bed sections 10.1 and 11.1 are assembled in the front needle bed 10 and in the rear needle bed 11.
- the needle beds 10 and 11 have different sections, namely the front needle bed 10, a section for needles of fineness 8 and a section for needles of fineness 4, and the rear needle bed 11 - as an example of possible variations - but only one single section with needles of gauge 8. It would also be possible here to select a section with needles of fineness 5 instead of a section with needles of fineness 8.

Description
Die Erfindung betrifft eine Flachstrickmaschine mit einem vorderen und einem hinteren, mit Nadeln besetzten Nadelbett, das jeweils aus einzelnen auswechselbaren Abschnitten zusammengesetzt ist.The invention relates to a flat knitting machine with a front and a rear needle bed, which is composed of individual interchangeable sections.
Es ist bereits bekannt oder vorgeschlagen worden, die Nadelbetten von Flachstrickmaschinen aus einzelnen Stegen, von denen jeweils zwei benachbarte den Führungskanal für eine Nadel begrenzen, zusammenzusetzen. Auch ist es bekannt, diese einzelnen Stege gruppenweise miteinander zu verbinden und diese Steggruppen als einzelne Abschnitte eines Nadelbettes aneinander zu reihen.It has already been known or proposed to assemble the needle beds of flat knitting machines from individual webs, two of which adjoin the guide channel for a needle. It is also known to connect these individual webs to one another in groups and to line these web groups together as individual sections of a needle bed.
Grundsätzlich ist auch die Idee bekannt, ein Nadelbett so zu gestalten, daß durch eine entsprechende Besetzung mit Nadeln auf ihm mit zwei Maschenfeinheiten gestrickt werden kann (DE-GM 18 72 478). Diese Idee läßt sich aber bisher nur in begrenztem Umfange oder nur bei älteren Maschinen mit einfachen Schloßsystemen verwirklichen, so daß sie bisher keine praktische Bedeutung erlangt hat.In principle, the idea of designing a needle bed in such a way that it can be knitted with two stitch finenesses by appropriately fitting it with needles is also known (DE-GM 18 72 478). So far, however, this idea can only be used to a limited extent or only with older machines realize with simple lock systems, so that it has so far gained no practical importance.
Der Erfindung liegt die Aufgabe zugrunde, eine moderne Flachstrickmaschine so auszubilden, daß auf ihr mit Nadeln unterschiedlicher Feinheit gearbeitet werden kann.The invention has for its object to design a modern flat knitting machine so that it can work with needles of different fineness.
Die gestellte Aufgabe wird mit einer Flachstrickmaschine der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß die Abschnitte der Nadelbetten eine unterschiedliche Nadelteilung aufweisen, so daß in benachbarten Nadelbett-Abschnitten Nadeln unterschiedlicher Feinheit eingesetzt sind.The object is achieved with a flat knitting machine of the type mentioned at the outset in that the sections of the needle beds have a different needle pitch, so that needles of different fineness are used in adjacent needle bed sections.
Bei der erfindungsgemäß ausgebildeten Flachstrickmaschine können die Nadeln unterschiedlicher Feinheit in beliebiger Weise auf die Nadelbetten verteilt sein, je nachdem, ob mehrere Einzelgestricke angefertigt werden sollen und ob bei diesen Gestricken Maschen unterschiedlicher Feinheit symmetrisch oder asymmetrisch verteilt sein sollen. Die auswechselbaren Abschnitte des Nadelbettes können unterschiedliche Länge haben, so daß unterschiedlich breite Bereiche von Maschen verschiedener Feinheit gestrickt werden können.In the flat knitting machine designed according to the invention, the needles of different fineness can be distributed in any way on the needle beds, depending on whether several individual knits are to be made and whether knits of different fineness should be distributed symmetrically or asymmetrically in these knitted fabrics. The interchangeable sections of the needle bed can have different lengths, so that areas of different widths of different fineness can be knitted.
Bei der Anwendung der Erfindung auf moderne Flachstrickmaschinen, die Schlitten mit mehreren Schloßsystemen aufweisen, können die einzelnen Schloßsysteme jeweils Nadeln unterschiedlicher Feinheit zugeordnet sein, und die Maschinen können so geschaltet und gesteuert werden, daß in den unterschiedlichen Abschnitten auch unterschiedliche Schloßsysteme die Arbeit der Maschenbildung übernehmen. Dabei kann zweckmäßig mindestens eines der mehreren Schloßsysteme sich von den anderen durch eine unterschiedlich ausgebildete Maschenumhänge-Steuerkurve unterscheiden.When the invention is applied to modern flat knitting machines which have slides with a plurality of lock systems, the individual lock systems can each be assigned needles of different fineness, and the machines can be switched and controlled in such a way that different lock systems also take over the work of stitch formation in the different sections . At least one of the several can be expedient Lock systems differ from the others by a differently designed mesh cap control curve.
Versuche haben gezeigt, daß eine erfindungsgemäß ausgebildete Flachstrickmaschine praktisch mit Nadeln aller gängigen Feinheiten bestückt werden kann. Vorteilhafterweise kann hierbei der Schlitten ein Strick- und Umhängeschloßsystem für Nadeln der Feinheit 2-4, eines für Nadeln der Feinheit 3-5, eines für Nadeln der Feinheit 4-6 und eines für Nadeln der Feinheiten 7 und 8 aufweisen. Bei Flachstrickmaschinen mit einer an sich bekannten elektronischen Steuereinrichtung, die eine Schlittenumkehr an jeder gewünschten Stelle der aus unterschiedlichen Abschnitten zusammengesetzten Nadelbetten erlaubt, bringt der Einsatz unterschiedlicher Schloßsysteme in unterschiedlichen Längenbereichen eines Nadelbettes keine Schwierigkeiten. Noch problemloser wird die Anwendung der Erfindung bei Strickmaschinen, bei denen für jede Nadel eines jeden Nadelbettes ein Einzelantrieb vorgesehen ist.Tests have shown that a flat knitting machine designed according to the invention can practically be equipped with needles of all common subtleties. Advantageously, the carriage can have a knitting and neck lock system for needles of fineness 2-4, one for needles of fineness 3-5, one for needles of fineness 4-6 and one for needles of
Anhand der beiliegenden schematischen Darstellung wird nachfolgend das Prinzip der Erfindung anhand eines Ausführungsbeispiels an einer Zweibett-Flachstrickmaschine mit einem Schlitten mit jeweils vier Schloßsystemen näher erläutert.The principle of the invention is explained in more detail below on the basis of an exemplary embodiment on a two-bed flat knitting machine with a carriage, each with four lock systems, using the attached schematic illustration.
Die schematische Zeichnung zeigt von einer Flachstrickmaschine das vordere Nadelbett 10 und das hintere Nadelbett 11, die beide aus unterschiedlich langen einzelnen Abschnitten 10.1 und 11.1 zusammengesetzt sind. Die Verbindungsstellen zwischen den einzelnen Abschnitten 10.1 und 11.1 der Nadelbetten 10 und 11 sind durch dicke strichpunktierte Linien angedeutet. Alle beim dargestellten Ausführungsbeispiel mit Nadeln besetzten Nadelbettabschnitte 10.1 und 11.1 sind mit Zahlen, 4, 6 oder 8 bezeichnet, welche die Nummern der Feinheit der dort eingesetzten Nadeln sind. Auf der Flachstrickmaschine sollen zwei getrennte Formgestrickteile 12 und 13 hergestellt werden. Aus diesem Grunde sind in den Nadelbetten Mittelabschnitte 10.2 und 11.2 vorhanden, in welche keine Nadeln eingesetzt sind, weil mit diesen Bereichen nicht gestrickt werden soll. Das eine Strickteil 12 soll fünf Bereiche unterschiedlicher Maschenfeinheit aufweisen, die auf ihm symmetrisch verteilt angeordnet sind. Die beiden äußeren Abschnitte 12.1 und 12.5 werden mit Nadeln der Feinheit 4, die angrenzenden Bereiche 12.2 und 12.4 mit Nadeln der Feinheit 6 und der mittlere Bereich 12.3 mit Nadeln der Feinheit 8 gestrickt. bei dem anderen Gestrick 13 sind zwei ungleich große und asymmetrisch angeordnete Gestrickbereiche vorgesehen, von denen der kleinere Gestrickbereich 13.1 mit Nadeln der Feinheit 8 und der größere Gestrickbereich 13.2 mit Nadeln der Feinheit 4 gestrickt werden soll. In den für die Bildung des Gestrickes 12 vorgesehenen Bereichen der Nadelbetten 10 und 11 sind im vorderen Nadelbett 10 und im hinteren Nadelbett 11 gleiche Nadelbettabschnitte 10.1 und 11.1 zusammengesetzt. Im Strickbereich für das Gestrick 13 weisen die Nadelbetten 10 und 11 jedoch unterschiedliche Abschnitte, nämlich das vordere Nadelbett 10 einen Abschnitt für Nadeln der Feinheit 8 und einen Abschnitt für Nadeln der Feinheit 4, das hintere Nadelbett 11 - als Beispiel für Variationsmöglichkeiten -jedoch nur einen einzigen Abschnitt mit Nadeln der Feinheit 8 auf. Es wäre hier auch möglich, anstelle eines Abschnittes mit Nadeln der Feinheit 8 auch einen Abschnitt mit Nadeln der Feinheit 5 zu wählen. Beim Umhängen von Maschen würde dann ein Nadelbettversatz Nadel um Nadel erfolgen und nach dem Umhängen einer Masche um eine Nadel der Versatz erneut angefahren werden. Bei einem bereits erwähnten Einzelnadelantrieb läßt sich der Umhängevorgang aber problemlos steuern.The schematic drawing shows the
Die schematische Zeichnung zeigt auch die beiden Schlittenhälften 14 und 15 für das vordere Nadelbett 10 bzw. das hintere Nadelbett 11. Jede Schlittenhälfte ist mit vier Schloßsystemen 14.1, 14.2, 14.3, 14.4 und 15.1, 15.2, 15.3 und 15.4 besetzt, die jeweils kombinierte Strick- und Umhänge-Schloßsysteme sind und durch Dreiecke symbolisiert sind. Jedes Schloßsystem ist einer anderen Nadelfeinheit zugeordnet, was durch die Bezeichnungen U4, U5, U6 und U7/8 zum Ausdruck gebracht ist. Dies bedeutet, daß die Schloßsysteme 14.1 und 15.1 zum Steuern der Nadeln der Feinheit 4, die Schloßsysteme 14.2 und 15.2 zum Steuern der Nadeln der Feinheit 5, die Schloßsysteme 14.3 und 15.3 zum Steuern der Nadeln der Feinheit 6 und die Schloßsysteme 14.4 und 15.4 zum Steuern der Nadeln der Feinheit 7 und 8 vorgesehen sind.The schematic drawing also shows the two
Nicht dargestellt sind in der Zeichnung eine elektronische Steuereinrichtung und die Antriebsvorrichtung für den Schlitten 14/15, die eine Schlittenumkehr an jeder gewünschten Stelle der Nadelbetten, also auch an jeder Übergangsstelle von einem Nadelbettabschnitt 10.1, 11.1 zum nächsten, und eine Auswahl der in den einzelnen Abschnitten 10.1, 11.1 der beiden Nadelbetten 10, 11 zum Einsatz gelangenden Schloßsysteme der Schlittenhälften 14, 15 erlauben.Not shown in the drawing are an electronic control device and the drive device for the
