What Types of Loom Motion Used in Weaving Factory?

Weaving Loom Motion | Primary Loom Motion | Secondary Loom Motion | Tertiary Loom Motion

Classification of Loom Motion in Weaving:
The motion of loom has classified into three, these are-

  1. Primary motion,
  2. Secondary motion,
  3. Tertiary motion.

All the above motions have explained in the below:

1. Primary Motion:
In order to interlace weft and warp yarn for producing woven fabric on any types of weaving machine three primary motions has needed. Those are-

  • Shedding motion,
  • Picking motion,
  • Beating motion.
Shedding Motion:
Shedding is the method of separating the warp yarn into two layers for producing tunnel (known as shed) is termed as shedding. In shedding process, some yarns are depressed down and some are raised up to form a tunnel.
Classification of Shedding:
This types of loom is not must for woven fabric production but it is used for higher production. It is classified into three types, which are-

  • Tappet shedding,
  • Dobby shedding,
  • Jacquard shedding.
Picking Motion:
The process of passing weft yarn from pirn package from one end to another end across the fabric through shed is known as picking. It should be noted here that, inserted weft yarn is termed as pick.
Classification of Picking:
Picking is classified into three types such as-

  • Over picking,
  • Under picking,
  • Modern picking.
Beating Motion:
Beating is the method of shoving the pick into the already woven fabric at a point is termed as feel of the cloth. One more thing is noted here, by pressure of ghost to joint feed side of the cloth is known as beating.

Classification of Beating:
Normally, beating is classified into three types such as-

  • Single beating,
  • Multiple beating,
  • Variable beating.
2. Secondary Motion:
Secondary motion is classified into two types, which are-

  • Take up motion,
  • Let off motion.
Take Up Motion:
Take-up motion is that motion which is used to draw the wounded fabric into the cloth beam during weaving. It is two types, one is positive and other one is negative take-up motion.

Let Off Motion:
Let off motion is that which supply warp yarn to the weaving zone at a perfect tension by unwinding and at a required rate from warper beam. It is also two types, one is positive let off motion and another one is negative let off motion (5 wheels, 7 wheels).

3. Tertiary Motion:
It is classified into five types, those are-

  • Weft stop motion,
  • Weft replenish,
  • Reed stop motion,
  • Warp stop motion,
  • Temple motion.
