2. To get an idea on dobby shedding mechanisms
3. To study on jacquard mechanism
4. To get knowledge on picking and beat up mechanism
5. To develop idea on take up and beat up mechanism.
6. To build an idea about auxiliary motion. Unit (1): Total lectures required = 12 Types of shuttle looms; Hand loom and power loom of various types. Classification of various loom mechanism and their objects, Passage of the warp and weft on shuttle loom, Shuttle and pirn. Drive to various parts of Loom and production calculation. Unit (2): Total lectures required = 12 Types of shed and classification of shedding mechanism. Tappet shedding: Lift of tappet, drive to tappet shedding. Negative and Positive tappet shedding mechanism. Limitation of tappet shedding Dobby shedding: Negative and positive dobby, working principle of knife dobby, Rotary cam dobby; Dobby card cutting cross border dobby, electronic dobby. Unit (3): Total lectures required = 12 Mechanical jacquard - Classification Figuring capacity, Harness ties, designing and card cutting-lacing Fundamental jacquards: SLSC, DLSC & DLDC, working principle, drive to various parts, Timing diagram. Brief study of Other fancy jacquard- self twilling, cross border jacquard, Electrical and Electronic Jacquard Unit (4): Total lectures required = 12 Mechanism of over pick and under pick motion; drive & timing diagram, Multiple box motion. Warp protector mechanism Beat up mechanism: Sley beat up mechanism, sley eccentricity and its effect on fabric properties. Unit (5): Total lectures required = 12 Take up motion- 5 wheel & seven wheel intermittent take up mechanisms- timing and setting. Let off- negative, semi positive mechanical and electronic let off mechanisms- timing and setting Warp stop motion- mechanical & electrical type its setting Weft stop motion- side and center weft fork motion- its timing and setting.
