ABSTRACT:
In an electric shedding control apparatus, shedding patterns are stored in memories in such a manner that the shedding patterns are compressed and the time required to read the shedding patterns is shortened. An electric shedding apparatus is provided for driving each of a plurality of heddle frames independently and in synchronization with a rotation of a main shaft of a loom. Constituents of the shedding operations are set in advance, and the constituents are selected for each shedding step. Also, in order to drive the heddle frame, shedding amount instruction for the heddle frame is output in accordance with the rotation of the loom main shaft based on a shedding curve which includes the selected constituents.
