Treadle (Pedal) in Handloom – Definition &
Function:-
Definition
A Treadle (also called a Pedal) is an essential part
of the handloom, usually made from wood, bamboo, or iron. It is located at the
bottom of the loom and is operated by the weaver’s feet.
Its main function is to divide the warp threads into
two or more layers to form a shed — the opening through which the shuttle
passes to insert the weft yarn.
Role of Treadle in Weaving
In a plain loom, there are usually two pedals.
In more complex or patterned weaves (like twill,
jacquard, or dobby), more than two pedals are used to control the design.
The treadles are connected to the heald shafts
(heddles) by tie-up cords.
When the weaver presses a treadle, the connected heald
shaft moves up or down, lifting or lowering specific warp threads.
This creates the shed, allowing the shuttle to pass
through with the weft.
Example: Twill Weave
If an ordinary twill weave requires 4 heald shafts, then:
4 treadles will be used.
Treadle 1 is connected to Heald Shaft 1,
Treadle 2 to Heald Shaft 2,
Treadle 3 to Heald Shaft 3,
Treadle 4 to Heald Shaft 4.
By pressing the treadles in a specific sequence, the
warp threads lift in patterns that form the twill design.
Importance in Handloom Sari Weaving
Controls the design formation by lifting the right set of warp threads.
Allows smooth and accurate shuttle movement.
Reduces manual strain by enabling foot operation
instead of hand-lifting heddles.
