Mr. Thomas is right, it's a term that the clerk uses to set a motion for a hearing date. The term comes from the old way that the clerk would organize the motion dates on "spindles." I imagine something like the link below. It is NOT the same as giving notice of the motion. Once the motion is filed and spindled for a date, notice of the motion and hearing date must be sent to the other side.
Cook County Circuit Court calls setting up a motion for hearing as a "Motion Spindled". This isn't a true legal term, but rather, terminology used by the Clerk's office within the computer system. Trust your paperwork that you receive and do not rely on the computer system.
