    摘要： Apparatus for determining status of weft insertion in a jet loom including weft arrival detection means (25) for detecting a weft inserted by injection of fluid is provided. The apparatus comprises clock means (K) for measuring a weft flying period (t1(s)) from the start time of insertion of a weft to the arrival time of the weft; and converting means (Co) for converting the weft flying period (t1(s)) into a weft flying angle (t1(t)) at standard rotational speed (R) of a weaving machine using the weft flying period (t1(s)) measured by the clock means and the standard rotational speed (R).

    摘要： A weft yarn detector is adapted to be used in an air-jet loom, in which weft insertion of a weft yarn through a reed passage is performed by air jet from a main nozzle and auxiliary nozzles. An optical sensor for detecting the extent of slack of the weft yarn is located in the reed passage at a position close to the main nozzle.

    摘要： There is provided a display device of an air jet loom (1) that includes a weft insertion device (2) causing a weft yarn (Y) released from a weft measuring and storing device (11) to move by compressed air injected from a main nozzle (7) and plural sub-nozzles (5) arranged in the direction of weft insertion, a setting and measuring device (21, 24, 28, 29, 37, 45) that serves to set and measure pressure or flow rate of the main nozzle (7) and also to set and measure pressure of the sub nozzle (5), and a controller (47) storing the measured pressure or flow rate of the main nozzle (7) and equipped with a display (61). The controller (47) causes the display (61) to show a line graph (63) representing pressure or flow rate of the main nozzle (7) with which weft insertion is completed at a previously set angular position of the air jet loom (1) for each of different predetermined pressures of the sub-nozzle (5).

    摘要： A auxiliary nozzle of an air jet loom includes a nozzle hole formed through a front wall of the auxiliary nozzle and having an inner opening opening to inside of the auxiliary nozzle and an outer opening opening to outside of the auxiliary nozzle. An axis extending in longitudinal direction of the auxiliary nozzle through axial center of the auxiliary nozzle is defined as center axis. An axis intersecting with the center axis and extending in a direction perpendicular to the front wall is defined as weft insertion axis. An axis extending through center of the inner opening and center of the outer opening is defined as nozzle hole axis. The nozzle hole axis is angularly spaced horizontally from the weft insertion axis. Weft insertion is accomplished by compressed air injected from the nozzle hole. The center of the inner opening is positioned on the weft insertion axis.

    摘要： A weft insertion apparatus in a jet loom, wherein the weft insertion apparatus includes an auxiliary nozzle (21) for weft insertion having an injection hole (23) from which air jet is ejected to deliver a weft (Y) in a weft guiding passage (14), is provided. The injection hole (23) is tapered so that the cross-sectional area of the hole (23) is decreased toward the direction of air injection of the auxiliary nozzle (21). The ratio A of a tapered angle γ of the injection hole (23) to a processing deflection angle β of the injection hole (23), γ/β = A, has the relationship expressed by an inequality (1): A ≥ A ⁢ 0 wherein A0 is the value of γ/β when the variation range (Δδmax) of the jet deflection angle (δ) becomes 0 when the injection pressure of the auxiliary nozzle (21) is changed from the maximum pressure (Pmax) for weft insertion to the minimum pressure (Pmin) for weft insertion.
