<p>Arrangement for a weaving loom with pneumatic introduction of the weft, comprising a four articulation drive mechanism of a weaving batten, a yarn magazine (20), at least one main nozzle (13) for introducing the wefts into an opening of the shed, as well as elements for guiding the airflow, particularly a series of air baffles (12). The arrangement is characterized in that the orientation elements of the airflow, particularly the series of air baffles (12) enabling the guiding of the yarns, the main nozzle (13) as well as the yarn magazine (20) are arranged on a same support (9, 9') which forms a medial link of the four articulation drive mechanism of the batten, mechanism with which it is formally connected by a coupling rod (3) and is movable therewith. The yarn magazine (20) has an inlet orifice (21) corresponding to an auxiliary nozzle (24) provided for the yarn insertion, a cover (22) parallel to a foot plate (36), as well as a retainer space which, in the yarn guiding direction, is delimited by a sidewall departing from a cross-section bisector symmetry plane, and presents in the yarn conveying direction a zone having a widening inner cross-section. The yarn magazine (20) must also be provided with an outlet orifice (23) enabling the extraction of the yarn and provided in the symmetry plane on the outer surface with respect to the inlet orifice (21). The retainer space has a zone with a cross-section which narrows into a portion contiguous to the enlarging cross-section, and it is provided with a sidewall having additional orifices (25) provided for the air supply.</p> |
