Abstract (en)
An electric shedding machine (1) of a loom includes heald frames (2), motors (3) driving the heald frames (2), a setting device (5), a storage device (7), a calculating device (8), and a controlling device (6). The setting device (5) sets a weaving condition including factors including a weaving pattern, rotational speed of the loom, weft type, weft density, and textile width. The storage device (7) stores a shedding motion condition database including weaving conditions and shedding motion conditions, which include a dwell period and a dwell phase and is related to the weaving conditions, to drive the heald frames (2). The calculating device (8), on the basis of the set weaving condition and the shedding motion condition database, immediately extracts the shedding motion condition corresponding to the set weaving condition when such corresponding shedding motion condition exists or performs interpolation calculation of a shedding motion condition corresponding to the set weaving condition from a weaving condition related to the set weaving condition when such corresponding shedding motion condition does not exist. The controlling device (6) controls rotations of the motors (3) on the basis of the extracted or interpolated shedding motion condition.
