Abstract
Filament threads such as rayon threads which may be smooth or partly texturized for protection, are texturized or entangled in the loom just prior to their insertion into a loom shed as weft threads. For this purpose a texturizer (4) is positioned between a filament thread supply spool (1) and a weft thread accumulator (3). The accumulator in turn is positioned just upstream of an air insertion nozzle (11) for injecting the weft threads into a loom shed. The texturizing is sufficient to lock the filaments into the filament thread body so that these texturized filaments form threads that can be pneumatically transported through the loom shed without causing so-called blow-outs of individual filaments out of the weft thread body.
