PROBLEM TO BE SOLVED: To provide a heald-opening device capable of freely setting optional opening curves and adjusting the amount of the opening without accompanying a complex operation. SOLUTION: This heald-opening device is equipped with a heald to which warp yarns are inserted, a linear motor for lifting up and down the heald and a controlling circuit for controlling the linear motor. The controlling circuit memorizes speed data rows for specifying the opening curve and commanding value-outputting timings, and controlling the linear motor based on the speed data rows and commanding value-outputting timings. |
