Auxiliary nozzle for a weaving machine

In an airjet weaving machine including a filling insertion duct including a U-shaped insertion duct having a lower portion, a reed, a batten pivotable about a batten axis, a shed area wherein longitudinally extending warp threads define a lower warp plane and at least one auxiliary nozzle in the form of a hollow needle and having a longitudinal centerline and being arranged to be moved about the batten axis in its generally longitudinal direction so it's tip moves into and out of the shed through the warp threads of the lower warp plane, said hollow needle comprising one or more outflow apertures in a wall adjoining a closed tip, the improvement comprising:

• said nozzle having a bulge at it's tip extending in a single direction only relative to it's centerline, said direction extending toward the reed.

An auxiliary nozzle for a weaving machine comprising a hollow, elongated needle having one or more outflow apertures in a wall adjoining an otherwise closed tip, said apertures being directed laterally in a first direction relative to a central longitudinal axis of the nozzle, and a single bulge located at the tip, said bulge extending laterally in a single second direction extending transversely of the longitudinal axis and generally perpendicular to the first direction.
