Abstract
An auxiliary nozzle for an air jet loom is configured as straight tubule closed and tapered blade-like at its free end and moveable with the loom batten into and out of the formed sheds. At least one blow aperture near the closed end of the tubule is provided in the shape of a slot extending essentially transverse to the tubule axis. The slot has a width not exceeding 0.8 mm and lateral walls configured so that the least or critical cross-section is bounded at least on one side by an edge having a thickness not exceeding 0.2 mm. If one edge is provided, it is located on the lower side of the slot toward the air supply and away from the closed end of the tubule. Various aperture configurations are disclosed.
