In order to make it possible to weave in a conductive thread, in particular an antenna thread, in a very wide variety of ways in a ribbon needle loom for manufacturing a strip, in particular a label strip, having a shedding apparatus for forming a shed (24) from warp threads (8), a weft insertion needle (26) for inserting weft thread loops, a reed (30) and having a feed apparatus (34) for a thread which has a blade (34) which dips into the shed (24) between warp threads (8) as far as under the insertion path of the weft insertion needle (26), it is proposed that the blade is arranged on a shaft (38) which is oriented transversely with respect to the warp direction. The shaft is connected to a first drive apparatus (40a) for performing a pivoting movement of the shaft. As a result of the pivoting, the blade (34) dips into and out of the shed (24). Furthermore, the shaft is connected to a second drive apparatus (44a) for movement in the axial direction. As a result, the blade (34) can be moved over the width of the strip (2).

Auf der der Eintragseite 4 gegenüberliegenden Seite 10 wird die Schussfadenschlaufe 6 mittels einer Wirknadel 28 in bekannter Weise abgebunden. Die eingetragene Schussfadenschlaufe 6 wird mittels eines Webblattes 30 an der Anschlagkante 32 angeschlagen.FIG. 2 schematically shows a needle ribbon loom 22 which is suitable for producing a ribbon fabric 2 of FIG. 1 with a conductor thread 14, but without a transponder chip 20. Warp threads 8 are opened by a shedding device not shown in detail to a shed 24 into which a weft thread loop 6 is inserted into the shed 24 with a weft insertion needle 26. On the entry side 4 opposite side 10, the weft loop 6 is tied off by means of a knitting needle 28 in a known manner. The registered weft thread loop 6 is struck by means of a reed 30 at the stop edge 32.
Zum Eintragen des Leiterfadens 14 dient ein Stecher 34, der am vorderen Ende eine Fadenöse 36 aufweist, durch die der Leiterfaden 14 geführt ist. Der Stecher 34 ist an einer Welle 38 befestigt, die mittels einer ersten Antriebsvorrichtung 40 eine Schwenkbewegung 42 ausführt, um den Stecher 34 zwischen Kettfäden 8 in das Webfach 24 einzustechen und zwar soweit, dass die Schlaufe des Leiterfadens 14 unter den Eintragweg der Schusseintragnadel 26 gerät. Dadurch wird der Leiterfaden in der gewünschten Position eingebunden und damit gesichert. Nach dem Ausfahren des Stechers 34 in die gestrichelt angedeutete Grundstellung G kann der Stecher 34 mittels einer zweiten Antriebsvorrichtung 44 in Linearbewegung 48 längs der Welle 38 über die Breite des Bandgewebes 2 verfahren werden, um den Stecher 34 an einer anderen gewünschten Stellung des Band- 5 gewebes 2 zwischen die Kettfäden 8 in das Webfach 24 einzubringen und zu befestigen. Im vorliegenden Beispiel sind die erste und die zweite Antriebsvorrichtung 40, 44 als kombinierter Linear- und Schwenkmotor 50 ausgebildet. Der Motor ist mit einer elektronischen Steuervorrichtung 52 verbunden, die zur mus- termässigen Steuerung der Nadelwebmaschine 22 und damit auch des Stechers 10 34 dient.To enter the conductor thread 14 is a piercer 34, which has at the front end a thread eyelet 36 through which the conductor thread 14 is guided. The engraver 34 is attached to a shaft 38, which performs by means of a first drive device 40 a pivoting movement 42 to stab the engraver 34 between warp threads 8 in the shed 24 and to the extent that the loop of the conductor 14 under the entry path of the weft insertion needle 26 device , As a result, the conductor thread is integrated in the desired position and thus secured. After extension of the engraver 34 in the dashed line indicated basic position G, the engraver 34 can be moved by means of a second drive device 44 in linear movement 48 along the shaft 38 across the width of the belt fabric 2 to the engraver 34 at another desired position of the band. 5 fabric 2 between the warp threads 8 in the shed 24 introduce and secure. In the present example, the first and the second drive device 40, 44 are formed as a combined linear and rotary motor 50.

Der Exzenterantrieb 62 ist über ein Hebelgetriebe 64 mit einer Schwinge 66 verbunden, die an einem Ende an einem Zapfen 68 verschwenkbar gelagert ist. Das andere Ende der Schwinge 66 wirkt mit einem An- 0 schlag 70 zusammen, der an der Schubstange 56 fest angeordnet ist. Die Rückholvorrichtung 60 kommt dann zum Einsatz, wenn die erste Antriebsvorrichtung 40a die Schubstange 56 nicht in die Grundstellung bewegt haben sollte, dann wird der Anschlag 70 mittels der Schwinge 66 und des Exzenterantriebes 62 in die gestrichelt dargestellte Grundstellung bewegt, in der der Stecher 34 den Webbereich der Nadelbandwebmaschine freigibt, sodass das Webblatt 30 die eingetragene Schussfadenschlaufe an der Anschlagkante 32 ungestört anschlagen kann.FIG. 4 shows a needle ribbon loom 22b, which is a development of the needle ribbon loom 22a of FIG. This IMadelbandwebmaschine contains a forced return device 60 for the engraver 34 in its dash-dotted lines indicated basic position G if the first drive device 40a should fail and the engraver 34 can not leave the web area. The return device 60 includes an eccentric drive 62, which is preferably connected in Fig. 5 not shown manner with the main drive shaft of the needle loom 22b and operates at the same frequency as the weft insertion needle 26. The eccentric 62 is connected via a lever mechanism 64 with a rocker 66, the is pivotally mounted at one end to a pin 68. The other end of the rocker 66 cooperates with an An 0 impact 70 which is fixedly arranged on the push rod 56. The return device 60 is then used when the first drive device 40a, the push rod 56 should not have moved to the home position, then the stop 70 by means of the rocker 66 and the eccentric 62 in the basic position shown in dashed lines moves, in which the engraver 34 releases the weaving area of the needle loom, so that the reed 30 can strike the registered weft loop at the stop edge 32 undisturbed.
Zur Sicherung der Nadelbandwebmaschine einerseits und des Bandgewebes andererseits kann anstelle der Rückholvorrichtung 60 der Stecher 34 mit einer Sollbruchstelle 72 versehen sein, die ausserhalb des Webbereiches liegt. Diese Sollbruchstelle kann zum Einsatz kommen einerseits wenn die zweite Antriebsvor- richtung 44a eine Linearbewegung 48 quer zum Bandgewebe 2 ausführt, noch bevor der Stecher 34 das Webfach 24 verlassen hat. Andererseits kann die Sollbruchstelle 70 zum Einsatz kommen, wenn das Webblatt 30 das Anschlagen der Schussfadenschlaufe 6 ausführt noch bevor der Stecher 34 in die Grundstellung G zurückgekehrt ist. To secure the Nadelbandwebmaschine one hand, and the tape fabric on the other hand, instead of the return device 60 of the engraver 34 may be provided with a predetermined breaking point 72, which is outside the weaving area. This predetermined breaking point can be used, on the one hand, when the second drive device 44a performs a linear movement 48 transversely to the belt web 2, even before the piercer 34 has left the shed 24. On the other hand, the predetermined breaking point 70 can be used when the reed 30 performs the striking of the weft thread loop 6 even before the piercer 34 has returned to the normal position G.
