Abstract
Mechanism models are introduced for rotary dobby, crank & cam shedding motions. Equations governing heald frame motion are derived. Heald frame motion curves are obtained and compared with each other. It is shown that higher heald frame maximum velocity & maximum acceleration, as well as a longer approximate heald frame dwell, are generated by the rotary dobby rather than the crank or cam shedding motions, due to the intermittent nature of the rotary dobby shaft motion.
