Loom Motions || Classification Of Loom Motions

Loom Motions

Loom motions are essential for fabric production. When different loom motions of a loom machine provide different facilities for weaving. Therefore, the weaving process stands for interlacing warp and weft yarn. In order to make a normal or fancy-designed fabric, indeed it is essential to weave. In fact, different types of looms facilities the weaving process. When loom run by a defined motion mechanism. Additionally, the loom is an essential piece of equipment for the weaving process. When a loom machine uses for producing woven fabric. Similarly, these loom machines drive in two ways such as manual system and automatic system. Here, I will point out the motion of the loom machine.

Classification Of Loom Motion:

In a weaving process, fabrics make up of different weaving processes. In order to produce weaved fabric, it is essential to do three necessary motions. The following are the motion types. They are-

  1. Primary motions
  2. Secondary motions
  3. Tertiary motions

Now, I like to classify the above classification. They are-

Primary Motions:

The mechanism without which it is not possible to weave a piece of fabric that stands for fundamental or primary motion. Primary motions are three parts. They are-

  • Shedding mechanism: Shedding mechanism separates warp yarns into two layers. Shedding helps to pass shuttle or other device from one part to other parts of shuttle box.
  • Picking mechanism: Picking motion facilites the weft yarn to run through shed. By the picking mechanism, weft yarn pass from one box to other box.
  • Beating mechanism: Beating push the newly inserted length of weft yarn.

The above three motions have a specific motion ratio, in which primary motion becomes complete.

Secondary Motions:

Secondary motions are also important after primary motion. They are-

  • Let-off motion: Let off motion is called warp control motion. This motion delivers warp yarn to weaving area at the required rate. Weavers beam also associates with let off motion.
  • Take-up motion: After weaving the fabric, it requires to collect the fabric in a roll form. As a result, take up motion withdraws fabrics from the weaving area at the constant rate.

Tertiary Motions or Auxiliary Motions:

Tertiary motion facilities to smooth the weaving process. This is done for high productivity and good quality of fabric. This is done additionally for this reason it is also called auxiliary motion. Tertiary motions are-

  • Warp stop motion: This motion facilite immidiate loom stop when a warp yarn or thred break down.
  • Weft stop motion: This motion also facilite immidiate loom stop when a weft yarn or thred break down.
  • Warp protector mechanism: Warp protection mechanism facilites to protect the warp threads by stopping the loom when the shuttle fails to reach the selvedge side and box properly into either the shuttle box during picking.
  • Warp mixing motion: Facilites different coloured weft yarn insert into the same fabric for check and stripe effect .
  • Brake: This mechanism facilites to stop the loom when a weft yarn breaks.
  • Feeler motion: This motion facilites to point out whether the weft yarn in pirn is almost used up or not.
  • Weft replenishment motion: This motion uses to provide uninterrupted filling insertion by switching from a depleted to a full package.
  • Selvedge cutting mechanisms: This mechanism facilies to cut selvedge.
  • Tension sensor: Tension sensor also use as auxiliary motion

Lastly, that’s all about different types of loom motions.

Additionally, in the weaving industry, different types of shuttle loom, shuttleless loom machines are used for fabric production. Finally, one has to know about the motions of the loom for better production efficiency.

  1. hi my name is nader rajabifam

    i am teacher in textile technology
    please send me any about textile
    we teach it with remember for my student who send it for me
    thanks
