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

a. Shedding mechanism
b. Picking mechanism
c. Beat-up mechanism

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:

1. Take-up motion


2. Let-off motion

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.
a. Weft stop motion
b. Warp stop motion
c. Warp protector mechanism
d. Weft replenishment / Warp mixing motion
e. Cutter
f. Temples
g. Brake
h. Selvedge
