Ribbon Needle Loom for Manufacturing a Strip, in Particular a Label Strip, Having a Woven-In Conductive Thread, in Particular Antenna Thread

Abstract

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 ( 40 a ) 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 ( 44 a ) for movement in the axial direction. As a result, the blade ( 34 ) can be moved over the width of the strip ( 2 ).
