Description

Zur Veränderung der Elastizitätseigenschaften eines Gestricks ist es bekannt, während des Strickvorgangs Schuss- und/oder Kettfäden einzulegen, wobei diese zusätzlichen Fäden entweder aus einem elastischen Garnmaterial oder aus einem relativ unelastischen Garnmaterial bestehen können, abhängig davon, ob die Elastizität des Gestricks in horizontaler und/oder vertikaler Richtung erhöht oder reduziert werden soll.To change the elastic properties of a knitted fabric, it is known to insert weft and / or warp yarns during the knitting process, which additional yarns may consist of either an elastic yarn material or a relatively inelastic yarn material, depending on whether the elasticity of the fabric is horizontal and horizontal / or vertical direction should be increased or decreased.

Das Einbringen von zusätzlichem Fadenmaterial in Form von Schuss- oder Kettfäden schränkt jedoch die Formgestaltung des Gestricks insbesondere bei dreidimensionalen Gestricken und die möglichen Bindungsarten deutlich ein. Außerdem verändern Schuss- und Kettfäden in der Regel auch das Aussehen des Gestricks, insbesondere wenn die Schuss- oder Kettfäden nur in bestimmten Bereichen des Gestricks eingelegt werden.The introduction of additional thread material in the form of weft or warp threads, however, restricts the shaping of the knitted fabric, in particular in the case of three-dimensional knitted fabrics, and the possible types of weave. In addition, weft and warp threads usually also change the appearance of the knitted fabric, especially if the weft or warp threads are inserted only in certain areas of the knitted fabric.

Die Bildung von Hohlkörpern auf einer Flachstrickmaschine unter Verwendung von Spickeltechniken sind aus der DE 39 37 406 C2 und der EP 874 076 A2 bekannt. Die Herstellung von Hohlkörpern mittels Maschensplitten und Transfertechniken ist ebenfalls bereits beschrieben worden.The formation of hollow bodies on a flat knitting machine using spooling techniques are known from US 5,178,237 DE 39 37 406 C2 and the EP 874 076 A2 known. The production of hollow bodies by means Mesh splitting and transfer techniques have also been described previously.

Die US 2004/172981 A1 beschreibt das Herstellen von Intarsiafeldern in einem Schlauch-Rundgestrick mithilfe von Intarsiafadenführern. Diese werden am Ende eines Strickvorgangs in das Intarsiafeld zurückbewegt und ihr Faden von einer leeren Nadel gefangen. Der Fanghenkel wird anschließend im benachbarten Intarsiafeld abgestrickt.The US 2004/172981 A1 describes the making of intarsia fields in a tubular knitted fabric using inlay yarn guides. These are moved back into the intarsia field at the end of a knitting process and their thread is caught by an empty needle. The tuck loin is then knitted in the adjacent intarsia field.

Die DE 196 36 208 A1 beschreibt die Herstellung eines mehrlagigen Gestricks mit Schuss- und Kettfadeneinlage, um die Querelastizität des Gestricks einstellen zu können. Die Gestricke kennen dabei auch Netzöffnungen aufweisen.The DE 196 36 208 A1 describes the production of a multi-layered knitted and warp-knitted fabric to adjust the cross-elasticity of the knitted fabric. The knits know while having mesh openings.

In der EP 0 408 977 A1 ist die Erhöhung der Stabilität eines Gestricks durch Umschlingen der Maschenschenkel von Maschen mit dem maschenbildenden Faden beschrieben.In the EP 0 408 977 A1 is the increase in the stability of a knitted fabric by looping the mesh legs of stitches described with the stitch-forming thread.

Die US 2009/325746 A1 offenbart die Herstellung einer Ballkarkasse, bei der die räumliche Struktur durch Variation der Maschengröße erreicht wird. Die notwendige Stabilität wird durch das verwendete Fadenmaterial erreicht. Durch die Verwendung eines Fadenmaterials mit hoher Zugfestigkeit wird auch bei dem in der WO 2014/013790 A1 offenbarten gestrickten Schuhoberteil die Stabilität erhöht.The US 2009/325746 A1 discloses the production of a ball carcass in which the spatial structure is achieved by varying the mesh size. The necessary stability is achieved by the thread material used. By using a thread material with high tensile strength is also in the in the WO 2014/013790 A1 revealed knitted shoe upper increases stability.

Die US 3 457 737 A beschreibt einen auf einer Rundstrickmaschine hergestellten Strumpf, bei dem in einzelnen Bereichen zusätzliche Fäden zur Erhöhung der Formstabilität mit eingestrickt werden können.The US 3,457,737 A describes a stocking produced on a circular knitting machine, in which additional threads can be knitted in individual areas to increase the dimensional stability.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren bereitzustellen, mit dem flächige oder räumliche Gestricke, insbesondere für Karkassen für Bälle, Schuhoberteile oder Fersenbereiche von Socken mit einer hohen Formstabilität ohne die Nachteile, die sich durch den Einsatz von Schuss- oder Kettfäden ergeben, hergestellt werden können.It is an object of the present invention to provide a process with which flat or spatial knitted fabrics, in particular for carcasses for balls, shoe uppers or heel regions of socks with a high dimensional stability without the disadvantages resulting from the use of weft or warp threads, can be produced.

Die Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen des Anspruchs 1.The object is achieved by a method having the features of claim 1.

An jedem Fixierpunkt wird der Fadenlauf im Gestrick unterbrochen. Entlang der gedachten Verbindungslinien zwischen den Fixierpunkten ist daher das Gestrick weniger elastisch als in den übrigen Bereichen. Durch eine entsprechende Verteilung der Fixierpunkte in einer Netz- oder Gitterstruktur über das Gestrick oder einen Teil des Gestricks kann dadurch die gewünschte Formstabilität erreicht werden. Je dichter die Fixierpunkte dabei liegen, desto formstabiler wird das Gestrick. Die Formstabilität wird beim erfindungsgemäßen Verfahren allein durch die Anordnung der Fixierpunkte im Gestrick sowie durch die Festigkeit des verwendeten Fadenmaterials erreicht.At each fixing point of the thread run is interrupted in the fabric. Along the imaginary connecting lines between the fixing points, therefore, the knit less elastic than in the other areas. By means of a corresponding distribution of the fixing points in a mesh or lattice structure over the knitted fabric or a part of the knitted fabric, the desired dimensional stability can thereby be achieved. The denser the fixing points, the more stable the knitted fabric becomes. The dimensional stability is achieved in the method according to the invention solely by the arrangement of the fixing points in the fabric and by the strength of the thread material used.

Die Netz- oder Gitterstruktur der Fixierpunkte kann dabei vorzugsweise derart ausgebildet werden, dass jeder Fixierpunkt mindestens zwei benachbarte Fixierpunkte aufweist. Dadurch lassen sich geschlossene Netz- oder Gitterstrukturen erzeugen, die die gewünschte flächige oder räumliche Formstabilität des Gestricks ergeben.The mesh or grid structure of the fixation points can preferably be formed such that each fixation point has at least two adjacent fixation points. As a result, it is possible to produce closed net or grid structures which produce the desired dimensional or spatial dimensional stability of the knitted fabric.

Zwischen den Fixierpunkten kann das Gestrick in einer beliebigen Bindung hergestellt werden. Die Bindung kann dabei so gewählt werden, dass die Formstabilitätseigenschaften unterstützt werden. Mit der Bindung können jedoch auch andere Eigenschaften wie Oberflächenbeschaffenheit, Saugfähigkeit oder dergleichen sowie die Optik des Gestricks beeinflusst werden.Between the fixing points, the fabric can be made in any binding. The bond can be chosen so that the dimensional stability properties are supported. With the bond, however, other properties such as surface finish, absorbency or the like and the appearance of the knit can be influenced.

Das Gestrick kann dabei mit Hilfe eines oder mehrerer Fadenführer hergestellt werden. Die Zahl der Fadenführer kann dabei davon abhängig gemacht werden, mit welcher Stricktechnik die Fixierpunkte erzeugt werden und wie die Bindung zwischen den Fixierpunkten gewählt wird.The fabric can be produced with the help of one or more yarn guides. The number of thread guides can be made dependent on which knitting technique the fixing points are generated and how the bond between the fixing points is selected.

Nach dem erfindungsgemäßen Verfahren werden die Fixierpunkte durch Umkehren der Strickrichtung innerhalb einer Maschenreihe und Bilden einiger Maschen in entgegengesetzter Strickrichtung, bevor wieder in der ursprünglichen Strickrichtung bis über die Umkehrstelle hinaus Maschen gestrickt werden, hergestellt, wobei nach dem Umkehren der Strickrichtung mindestens mit der ersten auf die Umkehrstelle folgenden Nadel keine Masche gebildet wird. Auf diese Weise ist es möglich, an jeder beliebigen Stelle innerhalb einer Maschenreihe einen Fixierpunkt zu erzeugen.According to the method of the invention, the fixing points are produced by reversing the knitting direction within a course and forming a few stitches in the opposite direction before knitting again in the original knitting direction beyond the reversing point, and after reversing the knitting direction at least with the first one the reversal point following needle no stitch is formed. In this way it is possible to generate a fixing point at any point within a course.

Dabei kann in die mindestens erste Nadel nach der Umkehrstelle ein Fanghenkel eingelegt, die Masche dieser Nadel oder Nadeln auf das gegenüberliegende Nadelbett umgehängt, diese Nadel oder Nadeln geflottet oder umschlungen werden, um den Fixierpunkt zu erzeugen.In this case, inserted into the at least first needle after the reversal point a tuck, the mesh of this needle or needles umgehängt on the opposite needle bed, this needle or needles are floated or looped around to create the fixation point.

Die durch die Herstellung eines Fixierpunktes im Höhenrapport des Gestricks zusätzlich gebildeten Maschen können im weiteren Strickverlauf wieder ausgeglichen werden.The stitches additionally formed by the production of a fixing point in the vertical repeat of the knitted fabric can be compensated again in the course of the knitting process.

Insbesondere bei regelmäßig geformten Gestricken ist es vorteilhaft, wenn die Fixierpunkte homogen über zumindest einen flächigen oder räumlichen Bereich des Gestricks verteilt werden, derart, dass das Gestrick in Maschenreihenrichtung und in Maschenstäbchenrichtung die gewünschte Formstabilität erhält.In particular, in the case of regularly shaped knitted fabrics, it is advantageous if the fixing points are distributed homogeneously over at least one areal or spatial area of the knitted fabric in such a way that the knitted fabric obtains the desired dimensional stability in the course direction and in the wale direction.

Dabei können die Fixierpunkte in Maschenstäbchenrichtung des Gestricks auch versetzt zueinander gebildet werden. Außerdem ist es möglich, innerhalb einer Maschenreihe mehrere Fixierpunkte zu bilden und/oder die Fixierpunkte auch in einer Start- und/oder Abschlusstrickreihe des Gestricks zu bilden.The fixing points in the wale direction of the knitted fabric can also be formed offset from one another. In addition, it is possible to form a plurality of fixing points within a row of stitches and / or to form the fixing points in a starting and / or final knitting row of the knitted fabric.

Sollten zusätzliche Maßnahmen notwendig sein, die Formstabilität des Gestricks zu erhöhen oder die Elastizität in Maschenstäbchen- und/oder Maschenreihenrichtung zu verändern, so können zumindest bereichsweise Kett- und/oder Schussfäden in das Gestrick eingelegt werden.Should additional measures be necessary to increase the dimensional stability of the knitted fabric or to change the elasticity in wale and / or course direction, warp and / or weft threads can be inserted into the fabric at least in some areas.

Weiter betrifft die Erfindung Karkassen für Bälle, Schuhoberteile und Fersenbereiche von Socken mit den Merkmalen des Anspruchs 12.Furthermore, the invention relates to carcasses for balls, shoe uppers and heel areas of socks with the features of claim 12.

Im Folgenden werden Ausführungsbeispiele erfindungsgemäßer Verfahren anhand der Zeichnung im Detail beschrieben.In the following, embodiments of the inventive method will be described in detail with reference to the drawing.

Fig. 1 zeigt die Abwicklung der Oberfläche eines kugelförmigen Gestricks 100. Zur Erzielung der kugelförmigen Gestalt nehmen während des Herstellungsprozesses in vorbestimmten Bereichen 1a - e, 2a - e nicht alle Nadeln einer oder mehrerer Strickreihen am Maschenbildungsprozess teil, während in den anderen Bereichen mit allen Nadeln über die gesamte Gestrickbreite Maschen gebildet werden (Spickeltechnik). Bei Wiederaufnahme der Maschenbildung in den Bereichen 1a - e und 2a - e werden die Abschnitte des Gestricks zusammengezogen, wodurch ein räumliches Gestrickstück entsteht. Fig. 1 shows the development of the surface of a spherical knit 100. In order to obtain the spherical shape in the manufacturing process in predetermined areas 1a - e, 2a - e do not take all needles of one or more rows of knitting in the knitting process, while in the other areas with all needles on the entire knit width stitches are formed (spooling technique). Upon resumption of stitch formation in areas 1a-e and 2a-e, the sections of the fabric are pulled together, creating a knitted fabric.

Die Wendepunkte 3a, 4a eines hier nicht dargestellten Fadenführers, mit welchem das Gestrick gebildet wird, sind, ausgehend von einer Mittellinie M des Gestricks, homogen über die gesamte Höhe und Breite des Gestricks verteilt, wodurch eine gleichmäßige Fadenbelastung in den Verbindungsbereichen 5a, 6a der einzelnen Segmente gewährleistet wird. Zusätzlich zu diesen Wendepunkten sind Fixierpunkte 7a, 8a innerhalb des Gestricks eingebracht.The turning points 3a, 4a of a yarn guide, not shown here, with which the fabric is formed, starting from a center line M of the knit, distributed homogeneously over the entire height and width of the knitted fabric, whereby a uniform yarn load in the connecting portions 5a, 6a of individual segments is guaranteed. In addition to these turning points, fixing points 7a, 8a are incorporated within the knitted fabric.

Diese Fixierpunkte können ebenfalls homogen über den gesamten Strickbereich verteilt angeordnet sein und bilden eine je nach den Stabilitätsanforderungen an den Gestrickbereich unterschiedlich geformte Gitter- oder Netzstruktur.These fixing points can also be distributed homogeneously over the entire knitting area and form a depending on the Stability requirements on the fabric area differently shaped grid or network structure.

Weiter ist die Bildung von Öffnungen im Gestrick möglich. In Fig. 2 ist eine schematische Darstellung einer Abwicklung eines Gestricks für ein Schuhoberteil 10 gezeigt, welches als räumliches Gestrickstück hergestellt wurde.Next, the formation of openings in the fabric is possible. In Fig. 2 is a schematic representation of a development of a knit fabric for a shoe upper 10 shown, which was produced as a spatial knitted piece.

Zur vereinfachten Darstellung sind hier lediglich die Außenkontur des Schuhoberteils 10 sowie die Bereiche, in welche Fixierpunkte 7a, 8a eingebracht wurden, dargestellt. Im dargestellten Beispiel sind die Fixierpunkte 7a, 8a wie auch in Fig. 1 homogen um eine Mittellinie M verteilt angeordnet. Die Fixierpunkte 7a, 8a sind hier in Bereichen des Schuhoberteils eingebracht, welche einer erhöhten Belastung beim Tragen des fertigen Schuhs ausgesetzt sind. Dies ist der Bereich der Ferse, der Zehen sowie des Sprungbeins, in welchem auch die Elemente zur Sicherung des Schuhs am menschlichen Fuß angebracht sind.For simplified illustration, only the outer contour of the shoe upper 10 and the areas into which fixing points 7a, 8a have been introduced are shown here. In the example shown, the fixing points 7a, 8a as well as in Fig. 1 arranged homogeneously distributed about a center line M. The fixing points 7a, 8a are introduced here in areas of the shoe upper, which are exposed to increased stress when wearing the finished shoe. This is the area of the heel, toes and ankle, in which the elements for securing the shoe are attached to the human foot.

Fig. 3 zeigt einen Strickablauf zur Herstellung eines Fixierpunktes innerhalb eines Gestricks. Die Schlittenrichtung wird mittels Pfeilen am linken Rand der Fadenlaufdarstellung dargestellt. Die Herstellung des Fixierpunktes geschieht im Inneren des Gestricks, das heißt, es wurden zuvor schon einige, hier nicht dargestellte Maschenreihen mittels eines ebenfalls nicht dargestellten Fadenführers gebildet, bevor in Reihe R1 eine Maschenreihe auf den Nadeln A - H des vorderen Nadelbetts in Schlittenrichtung nach rechts gestrickt wird. Die Nadel H bildet den Wendepunkt eines hier nicht dargestellten Fadenführers. Fig. 3 shows a knitting sequence for producing a fixing point within a knitted fabric. The carriage direction is represented by arrows on the left edge of the yarn guide. The preparation of the fixing point happens inside the knitted fabric, that is, there were already some, not shown here rows of stitches formed by a thread guide, also not shown, before row R1 on a row of stitches on the needles A - H of the front needle bed in the carriage direction to the right is knitted. The needle H forms the turning point of a thread guide, not shown here.

In Reihe R2 erfolgt eine Schlittenumkehr der Flachstrickmaschine nach links und das Bilden von Maschen auf den Nadeln G - C des vorderen Nadelbetts. Die Nadel H wird geflottet.
