Abstract
A stop-motion mechanism utilizes rotational means for rotating a shaft having a thread with an alternating series of helical portions and arc portions. A follower is mounted for motion having a longitudinal component, and is adapted to engage the thread formed on the rotatable shaft. When the shaft is rotated, the follower thus moves in an intermittent fashion which is characterized by alternating periods of motion having a longitudinal component and pauses in motion.
