Motions of Loom | Weaving Loom Motion | Primary Motions of Loom | Secondary Motions of Loom | Tertiary Motions of Loom

Loom Motions:
In order to interlace wrap and weft threads to produce a fabric, the following motions are necessary on any type of loom:
  1. Primary motions
  2. Secondary motions
  3. Tertiary motions

Motions of Loom
1. Primary Motions:
These are fundamental or essential mechanisms. Without these mechanisms, it is practically impossible to produce a fabric. It is for this reason that these mechanisms are called ‘primary’ mechanisms. The primary mechanisms are three in number. 2. Secondary Motions:
These mechanisms are next in importance to the primary mechanisms. If weaving is to be continuous, these mechanisms are essential. So they are called the ‘secondary’ mechanisms. They are:
3. Tertiary Motions:
To get high productivity and good quality of fabric, additional mechanisms, called auxiliary mechanisms, are added to a loom. The auxiliary mechanisms are useful but not absolutely essential. This is why they are called the ‘auxiliary’ mechanisms. These are listed below.
  • Weft stop motion
  • Warp stop motion
  • Warp protector mechanism
  • Weft replenishment / Warp mixing motion
  • Cutter
  • Temples
  • Brake
  • Selvedge
