Description
Stabkörper 12 üblicher Größe und Gestalt, dessen Nadeln 13 mit ihren verstärkten unteren Enden in einer nach oben offenen Metallschiene 14 angeordnet sind. Diese Metallschiene besteht aus Federstahl und ist mit einer Kunststoffüllung ausgegossen, die den Nadeln 13 einen festen Halt in der Metallschiene verleiht. Die Metallschiene 14 ist zusammen mit den darin sitzenden Nadeln 13 in den Stabkörper 12 eingebettet, der im Spritzguß aus Kunststoff hergestellt ist, und zwar vorzugsweise aus einem mit Glasfasern verstärkten Gemisch aus Polyamid und Graphit. Das mit Glasfasern verstärkte Polyamid ist zäh und verschleißfest, und der Graphitzusatz ergibt eine gewisse Selbstschmierung des Nadelstabes bei seiner Förderung längs der Führungsstäbe des Maschinenrahmens. Die Enden 15 der Metallschiene sind abgeflacht, wie sich aus F i g. 3 entnehmen läßt, so daß sie sich bis in den Bereich der Führungsteile des Nadelstabes erstrecken können.Rod body 12 of usual size and shape, the needles 13 with their reinforced lower ends in an upwardly open metal rail 14 are arranged. This metal rail is made of spring steel and is filled with a plastic filling that gives the needles 13 a firm hold in the metal rail confers. The metal bar 14 is embedded in the rod body 12 together with the needles 13 seated therein, which is made of plastic by injection molding, preferably from one with glass fibers reinforced mixture of polyamide and graphite. The polyamide reinforced with glass fibers is tough and wear-resistant, and the addition of graphite results in a certain self-lubrication of the needle bar when it is being conveyed along the guide rods of the machine frame. The ends 15 of the metal rail are flattened, as can be seen from FIG. 3 can be seen so that it extends into the area of the guide parts of the needle bar can extend.
Die Herstellung des Nadelstabes ist in F i g. 4 veranschaulicht. Hierfür wird eine Form 20 verwendet, die eine der Gestalt des Stabkörpers angepaßte Ausnehmung 21 aufweist. Die Form 20 ist über ihre ganze Länge bei 22 nach oben offen und weist eine Abdeckstange 22' mit einer Reihe von Löchern 23 auf, in die die Nadeln 24 von unten her eingesteckt sind, so daß sie mit ihren verstärkten Enden 25 nach unten hervorstehen. Zusätzlich ist eine Metallschiene 26 von U-förmigem Querschnitt vorgesehen, die aus Federstahl besteht und an ihren über die Nadelreihe herausragenden Enden 15 abgeflacht ist.The manufacture of the needle bar is shown in FIG. 4 illustrates. A form 20 is used for this, which has a recess 21 adapted to the shape of the rod body. The shape 20 is about her the entire length at 22 open to the top and has a cover rod 22 'with a series of holes 23 on, into which the needles 24 are inserted from below, so that they with their reinforced ends 25 after protrude below. In addition, a metal rail 26 of U-shaped cross-section is provided, which from There is spring steel and is flattened at its ends 15 protruding beyond the row of needles.
Die Metallschiene 26 und die zum Schließen der Form dienende Abdeckstange 22' mit den darin sitzenden Nadeln 24 werden dann so in die Form eingesetzt, daß sich die zu umgießenden Teile nicht berühren. Die Form wird dann mit dem Kunststoff ausgegossen und erst geöffnet, wenn der Kunststoff gehärtet ist. Z/weckmäßig wird bei der Herstellung so verfahren, daß zunächst die Abdeckstange mit den darin befindlichen Nadeln an entsprechenden Stützen so gehaltert wird, daß die Nadeln mit ihren verstärkten Enden 25 nach oben ragen. Sodann wird die Metallschiene 26 mit einer geeigneten Halterung mit ihrer Öffnung nach unten darübergesetzt, worauf die Form gleichfalls mit ihrer Öffnung nach unten über die Metallschiene gestülpt wird.The metal rail 26 and the cover rod 22 'which is used to close the mold and which are seated therein Needles 24 are then inserted into the mold in such a way that the parts to be encapsulated do not touch. The plastic is then poured into the mold and only opened when the plastic has hardened is. Z / weckewise, the process of manufacture is such that first the cover rod with the needles located therein is held on corresponding supports so that the needles with their reinforced Ends 25 protrude upwards. Then the metal rail 26 with a suitable holder with its Opening downwards over it, whereupon the form also with its opening downwards over it the metal rail is turned over.
Zur Herstellung des Nadelstabes können auch andere Kunststoffe, z.B. hart eingestelltes Polythen, benutzt werden.Other plastics, e.g. hard-set polythene, can be used to manufacture the needle bar. to be used.
Die Erfindung ist nicht auf Nadelstäbe für Nadelstabstrecken beschränkt, sondern kann auch zur Herstellung von Nadelstangen für andere Zwecke, z. B. zur Herstellung von Hechelkämmen, Hackern für Karden od. dgl., benutzt werden.The invention is not limited to needle bars for needle bar stretching, but can also be used for production of needle bars for other purposes, e.g. B. for the production of hackle combs, hackers for Cards or the like., Can be used.
Die die Nadelenden aufnehmende Metallschiene kann auch mit Rippen versehen oder wellenförmig gebogen sein, um ihr eine bessere Versteifung oder Biegsamkeit zu verleihen.The metal bar receiving the needle ends can also be ribbed or wave-shaped be curved to give it better rigidity or flexibility.
