Gegenstand vorliegender Erfindung ist eine solche Vorrichtung für Rundstrickmaschinen zur Herstellung plattierter Farbmuster mittels Kettenfäden, bei welcher die Maschinennadeln von den in deren Haken zu legenden Kettenfäden im Sinne von Fig. 14 »umkreist« werden und bei welcher zu diesem Zweck die Kettenfadenführer »innerhalb« der Nadelreihe angeordnet und »quer« zur Achsrichtung - der Maschinennadeln zu bewegen sind.The present invention relates to such a device for circular knitting machines for the production of plated color samples by means of chain threads, in which the machine needles are "circled" by the warp threads to be placed in their hooks in the sense of FIG and in which, for this purpose, the chain thread guides are arranged "within" the row of needles and "across" to the axial direction - the machine needles are to be moved.

Von den bisher bekannten derartigen Vorrichtungen unterscheidet sich diejenige der vorliegenden Erfindung im wesentlichen da--' durch, daß die Kettenfadenführer an einzeln beweglichen, in radialen Führungsnuten einer feststehenden Scheibe gelagerten Platinen angeordnet sind, und daß das Bewegen der Kettenfadenführer um die Maschinennadeln herum hervorgebracht wird, indem ihre Platinen beim Arbeiten auf feststehende Anschläge treffen und hierdurch eine den erforderlichen Bewegungen der Kettenfadenführer entsprechende . seitliche Ablenkung erfahren.From the previously known such devices that differs from that of present invention essentially because the warp thread guides to individually movable, mounted in radial guide grooves of a stationary disc plates are, and that the movement of the chain thread guides around the machine needles is brought about by their sinkers at Work on fixed stops and thereby make the required movements the chain thread guide accordingly. experience lateral distraction.

Durch diese Einrichtung wird erreicht, auch bei Maschinen mit engem Nadelzylinder, unter Beibehaltung des Umkreisens der Nadeln, für jede Nadel einen Kettenfaden anzuordnen und somit das Verarbeiten dieser Kettenfäden auf den unmittelbar nebeneinander stehenden Nadein sowie selbst noch bei großer Feinheit der Nadelteilung zu ermöglichen, weil die Kettenfadenführer dann gruppenweise nur an einer Platine vereinigt und demzufolge gruppenweise bewegt werden können. Richtet manThis device achieves, even with machines with a narrow needle cylinder, under Maintaining the circumference of the needles, arranging a chain thread for each needle and thus the processing of these warp threads on the needles standing directly next to one another as well as to enable the needle pitch even with great fineness, because the chain thread guide then combined in groups only on one board and consequently can be moved in groups. One judges

dann noch die zum Bewegen der die Kettenfadenführer tragenden Platinen dienenden, an sich bekannten Kurvenführungen so ein, daß sich die einzelnen Systeme derselben unabhängig voneinander ein- und ausrücken lassen, so erreicht man zugleich eine größere Vielseitigkeit der Muster, weil man es dann in der Hand hat, nach Belieben einzelne oder sämtliche Systeme ein- oder auszuschalten und gegebenenfalls den Zeitpunkt der Umschaltung verschieden zu wählen. Es entstehen dann außer Langstreifen karrierte Muster, ringelartige Muster usf.then the sinkers that are used to move the sinkers carrying the chain thread guides known curve guides so that the individual systems of the same are independent Allowing each other to move in and out, you achieve greater versatility at the same time the pattern, because you then have it in your hand, individual or all systems as you wish on or off and, if necessary, the time of switching to different Select. In addition to long stripes, checkered patterns, ring-like patterns, etc.

Die Zeichnung veranschaulicht in den Fig. 1 bis 6 ein Ausführungsbeispiel einer Plattiervorrichtung der neuen Art. Die Fig. 7 bis 14 sind schematische Darstellungen der Arbeitsbewegungen eines Kettenfadenführers bei der Umlegung einer Stricknadel.The drawing illustrates in FIGS. 1 to 6 an embodiment of a plating device of the new kind. FIGS. 7 to 14 are schematic representations of the working movements of a chain thread guide when turning a knitting needle.

Oberhalb des Nadelzylinder α ist konzentrisch zu diesem ein nach Art einer sog. Rippscheibe an Rundränderstrickmaschinen ausgebildetes Bett e angeordnet (Fig. 1). Dieses Bett besitzt radiale Nuten zur Aufnahme und Führung von Platinen h, die als Schaft für die an diesen zu befestigenden Kettenfadenführer i dienen. Bei feiner Nadelteilung wird die Anzahl der Führungsnuten im Bette e zweckmäßig auf die Hälfte derjenigen im Nadelzylinder α bemessen. Die Anzahl der Platinen h und die Verteilung derselben in den Führungsnuten ist beliebig, sie wird dem jeweils herzustellenden Muster angepaßt.Above the needle cylinder α , a bed e designed in the manner of a so-called dial on circular-edged knitting machines is arranged concentrically to it (FIG. 1). This bed has radial grooves for receiving and guiding sinkers h, which serve as a shaft for the chain thread guide i to be attached to them. In the case of a fine needle pitch, the number of guide grooves in bed e is expediently dimensioned to be half that in needle cylinder α. The number of boards h and the distribution of the same in the guide grooves is arbitrary, it is adapted to the particular pattern to be produced.

thread guide i set up. The chain thread guides can be designed as small tubes or as a perforated needle and the like (FIGS. 1 and 4 to 6); their distribution in the shaft h can advantageously take place in such a way that they form a group with the same number of associated knitting needles. The radial movement of the sinkers or shafts h takes place through a lock g, which, like that for the knitting needles, can be arranged in multiple repetitions, so that with a single turn of the lock jacket / the knitting needles and the thread guides have worked several times. The said radial movement of the chain thread guides takes place at the point in time at which the knitting needles b have returned to the position shown in FIG. In this position, the knitting needles are kept by appropriate design of the jacket lock until they are wrapped with chain threads. When driving outwards, each sinker h, after its chain thread guide has reached the front side of the knitting needles (see slight bend (Fig. 9), in order to finally get behind the stop m by virtue of its spring force with the nose k (Fig. 10). During the return movement of the sinkers h that now takes place, their nose k hits the stop m (FIG. 11), whereby each of the sinkers is subjected to such a lateral displacement (FIG. 12) that the thread guide i, which when moving forward between the Needles 4 and 5 has passed, passes through the next gap present between needles 5 and 6 and, after returning to the starting position of FIG. 13, has described the path around needle 5 that can be seen in FIG is finished. If a platinum has several thread guides, they all execute the described movement at the same time, so that all of the needles corresponding to them are wrapped with chain threads. After the laying down, the knitting needles receive the basic thread from the thread guide c, whereupon the trimming takes place in a known manner. The work of the chain thread guide can be interrupted in that the rotatably set-up expulsion part of the lock g is set inwards in the manner known from dial locks of round-edged knitting machines, thereby rendering it inoperative. Instead of arranging the bed e for the chain thread guide inside the row of needles and in the form of a plate, it could also be arranged outside the row of needles or outside the ring η and designed as a circular ring. ■ Patent claims:

1. Device for circular knitting machines for turning the needles with chain threads for the purpose of generating plated color patterns, in which the chain thread guides are arranged within the row of needles and are to be moved transversely to the axial direction of the machine needles, characterized in that the chain thread guides (i) on individually movable, in radial guide grooves A stationary disc (e) mounted sinkers (h) are arranged, which sinkers (h) hit fixed stops (m ) during their working movement and thereby experience a lateral bending in such a way that the chain thread guides encircle the needle belonging to them.

2. Apparatus according to claim 1, characterized in that the curved guides (locks g) used for the radial movement of the sinkers (h) carrying the chain thread guides can be engaged and disengaged.
