What process did later engineers automate in the Spinning Mule to create the Self-Acting Mule?
Answer
The manual spinning and stretching of fibers during the drawing process.
Subsequent engineers, like Robert Smith and Richard Roberts, refined the Mule by automating the draw and spin cycle, using cams and linkages to replace the human hand during these critical stages.
