    摘要： In a loom including a shedding device (2) that includes a shedding motor (23) independent from a main shaft motor (13) of the loom as a driving source and that displaces each of healds in an up-down direction as a single drive shaft (22) that is common to all of the healds is driven by the shedding motor (23), a rotation amount of the drive shaft (22) in each weaving cycle is detected at least when the loom is performing a normal operation, and driving of the main shaft motor (13) is controlled so that a main shaft (12) of the loom is rotated so as to be synchronized with the drive shaft (22) in accordance with a detection signal indicating the detected rotation amount.

    摘要： A manufacturing apparatus (1) includes a support structure (50, 80) which supports a lay-up head (20) and a trimming head (70), a guide member (51, 81) which is provided corresponding to the support structure (50, 80) and supports the support structure (50, 80) so that the support structure is movable along a lay-up base (40), and a driving mechanism (58, 78) which moves the support structure (50, 80) on the guide member (51, 81), in which in the lay-up process, the support structure (50, 80) allows the trimming head (70) supported on the support structure (80) to be placed in a trimming head (70) retracted position which does not interfere with the lay-up head (20), in the trimming process, the support structure (50, 80) allows the lay-up head (20) supported on the support structure (50) to be placed in a lay-up head (20) retracted position which does not interfere with the trimming head (70).

    摘要： The invention provides a method of setting weft travel information for an air jet loom, a jetting mode of each sub-nozzle (S) being determined based on weft travel information about an expected weft travel status allowing the weft travel status to be plotted in a travel line form in a graph region whose horizontal and vertical axes indicate a rotational angle of a loom main shaft (15) and a distance from a weft-insertion start position in a weaving-width direction, weft insertion being executed under weft-insertion conditions including the jetting mode and a target weft arrival timing. The method includes setting first and second positions on weft-supply and opposite sides; determining that the travel line is bent at first and second bend points at the first and second positions; and setting the second bend point using the rotational angle based on the target weft arrival timing, and the second position.
