Abstract (en)

In a shedding apparatus for driving a heald frame assembly of a loom by a shedding drive motor installed independent of a loom driving motor, a shedding control apparatus which can ensure enhanced stability of motion of the heald frame while suppressing the power consumption to a minimum. The shedding control apparatus for controlling the shedding drive motor through a feedback loop includes a first rotation control pattern storing unit for storing a first rotation control pattern, a second rotation control pattern storing unit for storing a second one, a control pattern generating circuit for generating the second rotation control pattern and a selecting circuit. The control pattern generating circuit generates the second rotation control pattern on the basis of the rotation speed information obtained from a rotary encoder. The selecting circuit is so designed as to select the first or second rotation control patterns on the basis of the rotation speed changing information obtained from the rotary encoder. <IMAGE>
