Description
Das Aufschneiden von Maschen von Gestricken und Gewirken ist seit langem insbesondere zur Herstellung von Plüschgestricken bekannt. So beschreiben beispielsweise die
Weiter ist es beispielsweise aus der
Die bekannten Lösungen beziehen sich alle auf Rundstrickmaschinen und haben außerdem den Nachteil, dass sie aufwändig in der Herstellung sind, die Möglichkeiten der Maschenbildung einschränken und außerdem die Funktionssicherheit der Maschine beeinträchtigen können.The known solutions all relate to circular knitting machines and also have the disadvantage that they are expensive to manufacture, limit the possibilities of stitch formation and also can impair the reliability of the machine.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Möglichkeit zum Auftrennen von Maschen oder Fanghenkeln während des Strickvorgangs auf einer Flachstrickmaschine zu schaffen, die auch auf doppelflächige Gestricke anwendbar ist und die Maschenbildung nicht einschränkt.The present invention has for its object to provide a way to separate stitches or tuck loops during the knitting process on a flat knitting machine, which is also applicable to double-surface knitted fabrics and does not limit the stitch formation.
Die Aufgabe wird gelöst durch eine Flachstrickmaschine mit mindestens zwei gegenüberliegend angeordneten Nadelbetten, die jeweils mit einer Vielzahl von Nuten versehen sind, in denen Nadeln längsverschiebbar gelagert sind, die dadurch gekennzeichnet ist, dass mindestens oberhalb eines der Nadelbetten mindestens ein Schneidelementbett angeordnet ist, das mit einer Vielzahl von Nuten versehen ist, in denen Schneidelemente zur Auftrennung von auf den Nadeln gebildeten Maschen oder Fanghenkeln längsverschiebbar angeordnet sind.The object is achieved by a flat knitting machine with at least two oppositely arranged needle beds, which are each provided with a plurality of grooves in which needles are mounted longitudinally displaceable, which is characterized in that at least above one of the needle beds at least one cutting element bed is arranged with a plurality of grooves is provided, in which cutting elements are arranged to longitudinally displaceable for the separation of stitches formed on the needles or tongs.
Durch die in einem separaten Bett gelagerten Schneidelemente ist die Maschenbildung der Strickmaschine in keiner Weise durch die Schneidelemente beeinflusst. Es lassen sich somit ein- und doppelflächige Gestricke sowie Schlauchgestricke in Plüschqualität herstellen. Auch die Musterung der Gestricke ist in keiner Weise beschränkt. Die Lagerung der Schneidelemente in einem oder mehreren separaten Betten ermöglicht auch eine präzise Ansteuerung sowohl der Nadeln als auch der Schneidelemente. Die Funktionssicherheit der Maschine ist daher sehr hoch.Due to the cutting elements mounted in a separate bed, the knitting of the knitting machine is in no way influenced by the cutting elements. It is thus possible to produce single-layer and double-sided knitted fabrics as well as tubular knits in plush quality. The pattern of knitted fabrics is in no way limited. The storage of the cutting elements in one or more separate beds also allows precise control of both the needles and the cutting elements. The reliability of the machine is therefore very high.
Bei einer bevorzugten Ausgestaltung der Maschine entspricht die Nutenteilung des mindestens einen Schneidelementbetts der Nutenteilung der Nadelbetten oder einem Vielfachen der Nutenteilung der Nadelbetten. Somit kann jeder Nadel oder auch jeder zweiten, dritten oder vierten Nadel ein Schneidelement zugeordnet werden. Zum Schneiden der Maschen oder Fanghenkel ist kein seitlicher Versatz der Nadelbetten oder des Schneidelementbetts erforderlich, kann aber bei Teilungen des Schneidelementbetts gröber als die Teilung des Nadelbetts vorgesehen sein.In a preferred embodiment of the machine, the groove pitch of the at least one cutting element bed corresponds to the groove pitch of the needle beds or a multiple of the groove pitch of the needle beds. Thus, each needle or every second, third or fourth needle can be assigned a cutting element. No lateral offset of the needle beds or cutting element bed is required to cut the loops or tuck loops, but may be coarser than the pitch of the needle bed at pitches of the cutting element bed.
Weiter ist es von Vorteil, wenn die Länge des mindestens einen Schneidelementbetts gleich der Länge der Nadelbetten ist. Es können dann Plüschgestricke über die gesamte Länge der Nadelbetten erzeugt werden und nicht nur in bestimmten Bereichen der Nadelbetten.Further, it is advantageous if the length of the at least one cutting element bed is equal to the length of the needle beds. It can then be produced plush knits over the entire length of the needle beds and not only in certain areas of the needle beds.
Es lassen sich auch mehrere Schneidelementbetten nebeneinander oberhalb mindestens eines der Nadelbetten anordnen, wobei jedes Schneidelementbett einem Teilbereich des darunter liegenden Nadelbetts zugeordnet ist. Die einzelnen Schneidelementbetten können dabei die gleiche oder eine unterschiedliche Nutenteilung aufweisen.It is also possible to arrange a plurality of cutting element beds side by side above at least one of the needle beds, wherein each cutting element bed is associated with a portion of the underlying needle bed. The individual cutting element beds can have the same or a different groove pitch.
Zum Auftrennen der Maschen oder Fanghenkel eines Nadelbetts können diese von den Nadeln, auf denen sie sich befinden, auf die Schneidelemente eines über diesem Nadelbett angeordneten Schneidelementbetts übergeben werden. Die Schneidelemente werden hierzu von der Nadelbettenseite her zwischen die Schenkel der Maschen oder Fanghenkel eingeführt.For separating the stitches or tuck loops of a needle bed, these can be transferred from the needles on which they are located to the cutting elements of a cutting element bed arranged above this needle bed. For this purpose, the cutting elements are introduced from the needle bed side between the legs of the stitches or tuck loops.
Das mindestens eine Schneidelementbett kann jedoch auch so angeordnet werden, dass die zu schneidenden Maschen oder Fanghenkel von den Nadeln eines Nadelbetts auf die Schneidelemente eines oberhalb des gegenüberliegenden Nadelbetts angeordneten Schneidelementbetts übergebbar sind. Die Schneidelemente des oberhalb des gegenüberliegenden Nadelbetts angeordneten Schneidelementbetts werden dabei von der Kammspaltseite zwischen die Schenkel der Maschen oder Fanghenkel eingeführt.However, the at least one cutting element bed can also be arranged such that the stitches or tuck loops to be cut can be transferred from the needles of a needle bed to the cutting elements of a cutting element bed arranged above the opposing needle bed. The cutting elements of the above the opposite needle bed arranged cutting element bed are introduced from the comb gap side between the legs of the mesh or tuck loops.
Bei einer bevorzugten Ausgestaltung der Flachstrickmaschine können dabei die zu schneidenden Maschen oder Fanghenkel durch Austrieb der Nadeln auf die Schneidelemente des mindestens einen Schneidelementbetts übergebbar sein. Durch einen entsprechenden Austrieb der Nadel werden die Maschen oder Fanghenkel über den Kammspalt angehoben, sodass durch einen Austrieb der Schneidelemente diese in die Masche oder den Fanghenkel eingeführt werden können. Der Austrieb der Nadeln und Schneidelemente kann beispielsweise über Schlossteile am Maschinenschlitten erfolgen.In a preferred embodiment of the flat knitting machine, the stitches or tuck loops to be cut can be transferred to the cutting elements of the at least one cutting element bed by ejection of the needles. By a corresponding expulsion of the needle, the stitches or tuck loops are lifted over the comb gap, so that they can be introduced into the mesh or the tuck loops by a sprouting of the cutting elements. The expulsion of the needles and cutting elements can be done for example via lock parts on the machine slide.
Die Flachstrickmaschine kann jedoch auch so ausgebildet werden, dass die zu schneidenden Maschen oder Fanghenkel durch eine Bewegung der Schneidelemente des mindestens einen Schneidelementbetts auf die Nadeln zu und ohne Austrieb der Nadeln auftrennbar sind. Die Schneidelementbetten können hierzu in einem relativ großen Winkel zu den v-förmig angeordneten Nadelbetten ausgerichtet und die Schneidelement entsprechen weit ausgetrieben werden.However, the flat knitting machine can also be designed such that the stitches or tuck loops to be cut can be separated by movement of the cutting elements of the at least one cutting element bed onto the needles and without ejection of the needles. For this purpose, the cutting element beds can be aligned at a relatively large angle relative to the needle beds arranged in a v-shape and the cutting elements can be driven out far enough.
Zur Erleichterung des Einführens der Schneidelemente zwischen die Schenkel der zu schneidenden Maschen können die Nadeln vorzugsweise so genannte Kastenfedern zur Spreizung der zu schneidenden Maschen aufweisen.To facilitate the insertion of the cutting elements between the legs of the meshes to be cut, the needles may preferably have so-called box springs for spreading the meshes to be cut.
Die Ausstattung der Nadeln mit Kastenfedern ist jedoch nicht zwingend. Die zu schneidenden Maschen oder Fanghenkel können auf dem Nadelhaken, dem Nadelhals, einer Kastenfeder, der geöffneten oder geschlossenen Nadelzunge oder dem geschlossenen Schieber einer Schiebernadel liegend auf ein Schneidelement übergebbar und/oder durch dieses schneidbar sein. Es sind somit keine besonderen Anforderungen an die verwendeten Nadeln nötig.The equipment of the needles with box springs is not mandatory. The stitches or tuck loops to be cut can be transferred to the cutting hook, the needle neck, a box spring, the open or closed needle tongue or the closed slider of a needle on a cutting element and / or can be cut by this. There are thus no special requirements for the needles used.
