This book describes speed frames with respect to four important mechanisms: flyer and bobbin drives, cone drums for varying the 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 improved drafting systems, use of servo‑motors to vary bobbin speed according to changes in diameter and electronic controls are explained.

Features:

• Covers all important aspects of the modern speed frame, including the conventional process
• Describes defects and remedies, as well as calculations on the roving frame
• Includes an exclusive chapter on the features of the modern fly frame
• Highlights features of the few latest speed frames

This book is intended for graduate students and professionals in the textile industry.
