    摘要: In some embodiments, a method includes providing a first controller; providing a second controller; using the second controller to control a plurality of valves to provide a sequence of air jets that propel a weft thread across at least a portion of a weft insertion region of an air jet loom; and using the first controller to control at least one aspect of the air jet loom not controlled by the second controller. In some embodiments, a method for a controller in an air jet loom includes (a) defining a reference loom configuration; (b) determining a characterization of the reference loom configuration; (c) determining a modified loom configuration by at least one change to the reference loom configuration; (d) determining a characterization of the modified loom configuration; and (e) revising the reference loom configuration if the characterization of the modified loom configuration satisfies a criteria.

    摘要: To provide a weft control system capable of adjusting weft feed rate correctly and easily, there is disclosed a weft control system for looms consisting of a weft length measuring system (1) comprising a length measuring roller (1a) and a pinch roller (1b), a weft feeding system comprising a gripper (4) and a nozzle (3), and weft arrival sensors (6 and 7) installed in the weft arriving position in the loom. The weft control system has a process to store the weft arrival measurement value measured by weft arrival sensors, a process to calculate the average weft arrival value for a certain number of picks, a process to compare the derived average arrival value with a preset reference target value, and a process to control the weft length measuring system based on the result of comparison performed in the preceding process.

    摘要: The present invention relates to a method of controlling operating speed (N i ) of the loom for increasing the production rate (P) by varying the operating speed (N i ) to be increased. The method comprises a step of estimating a stop rate (n̂) at the final point of time during a predetermined period at a certain time during the predetermined period, comparing the estimated stop rate with a predetermined limit stop rate (Q S ), and setting the operating speed (N i ) to increase when the estimated stop rate (n̂) is less than the limit stop rate (Q S ) and to decrease when the estimated stop rate (n̂) exceeds the limit stop rate (Q S ).
