This book describes speed frame with respect to four important mechanisms: flyer and bobbin drive, 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 improved drafting systems, use of servo motors for varying the bobbin speed according to change in its diameter and electronic controls are explained.

Features:

• Covers all important aspects of modern speed frame including conventional process
• Describes defects and remedies as well as calculations on roving frame
• Includes an exclusive chapter of modern fly frame
• Discusses all the latest versions of speed frames
• Explores overall improvement in machine and labour efficiency to make it a high production frame.

This book is aimed at graduate students, researchers and professionals in textile and industrial engineering.
