    摘要： 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.

    摘要： A method for supplying weft threads to the weft of a weaving machine includes the steps of leading the thread successively through two thread accumulators, one of which is a prewinder which at each insertion releases a length of thread equal to the thread length required, and the second of which is a thread accumulator which has a lower draw-off resistance than the prewinder, and which provides a thread accumulation consisting of at least a part of the length of thread released from the prewinder. An apparatus for implementing the above method includes the above-mentioned two accumulators and control means for controlling thread insertion nozzles and also a thread clip on the low-resistance accumulator which determines the beginning of insertion and a magnetic pin on the prewinder which controls the end of insertion.

    摘要： A blow device for weft threads in weaving machines, in particular a blow device which makes use of a nozzle of the type which consists of a housing, a thread guide duct extending through the housing and a first or main blower situated in the housing and working with the thread guide duct to transport a weft thread to the shed of the weaving machine. The nozzle has a second or threading blower also situated in the housing that cooperates with the thread guide duct for threading the nozzle. The second blower has at least one blow duct which intersects the thread guide duct at an angle so as to thrust a weft thread presented at the entry of the thread guide duct through the thread guide duct when supplied with air. A central system deactivates the main blower when the threading blower is activated.

    摘要： An apparatus for fluidly injecting a weft thread into the shed of a weaving loom with increased force exerted on the weft thread consists of a main injection nozzle and a fluid jet injection tube of predetermined length and constant cross section diameter fixed coaxially to the exit passage of the nozzle, with the tube having a plurality of fluid outlet openings positioned in groups, with the openings located symmetrically to the axis of the tube and with the openings of each group intersecting a single plane to permit and symmetrical of the equal egress fluid from the tube through each of the openings.
