Principles of Spinning: Speed Frame in Spinning

This book describes speed frames with respect to four important mechanisms: flyer and bobbin drives, cone drums for varying speed of bobbins, differential motion to give combined speed to bobbins and a complicated building mechanism where modern speed frames score over conventional frames. This book also gives a detailed explanation of traditional mechanisms common in both types of frames, along with the path of roving from the nip of last drafting rollers to the flyer top. Concepts like im...
