  3. Woven Cloth

  4. Loom Development  Up right Vertical Frame  Semi Automatic Loom.  Chittaranjan Loom  Salvation army loom  Hattersley Loom.  Ordinary Power Loom  Automatic Power Loom- it was invented in 1890 to 1899 Christ.  Shuttle-less or Modern Loom (a) Projectile (b) Rapier (c) Air jet (d) Water jet (e) Multiphase  Shed Stick Weaving  Primitive or Throw- Shuttle Loom.  Fly Shuttle Loom-This was invented by the John Kay of Bury in 1733 A.D.  Fly- Shuttle –Pit loom  Fly- Shuttle- Frame loom

  7. Basic Mechanism of Weaving

  8. Different Parts of a Loom:

  9. Function of Loom parts

  10. Motions of Weaving:

  11. Loom Motions  Primary motions  Secondary motions  Tertiary motions

  12. Primary Motions:

  13. Secondary Motions  Take-up motion: The function of this motion is  To pull the cloth forward after beat up of weft  To maintain the same pick density and spacing  To wind the woven cloth on to a roller  Let-off motion: The function of this motion is  To allow the warp to unwind from the beam  To maintain an average tension of warp

  14. Tertiary Motions  Weft stop motion  Warp stop motion  Warp protector mechanism  Weft replenishment / Warp mixing motion  Cutter  Temples  Brake motion  Feeler Motion

  15. Tertiary Motions

  16. Sources of driving power  Hand loom: Human power drive.  Power loom:  Water Wheel.  Steam engine.  Diesel engine.  Electric motor.

  17. Methods of driving:  Single Large common motor (200 loom/motor)  Grouped motor e.g. 200 loom/motor  Individual motor:  Multiple motor:

  18. Loom Brake
