Different Types Of Shafts On Loom
In looms, shafts (also referred to as harnesses) are integral components that control the movement of warp threads during the weaving process. Different types of shafts on looms serve various purposes depending on the loom type and weaving requirements. Here are the main types:
1. Plain Shaft:
Used for simple weaves like plain weave.
Each shaft lifts specific warp threads to create the interlacement with the weft.
2. Twilling Shaft:
Designed for twill weaves.
Multiple shafts are used (at least 3 or 4) to create diagonal patterns.
3. Jacquard Shaft:
Used in looms with a jacquard mechanism.
Allows individual control of each warp thread for complex patterns and designs.
4. Dobby Shaft:
Used in dobby looms.
Designed to handle intermediate levels of complexity in patterns, requiring fewer shafts than jacquard systems.
5. Tappet Shaft:
Used in tappet looms.
Works with cams or tappets to lift shafts in a pre-set sequence, suitable for simpler weaves.
6. Drop Box Shaft:
Found in looms with drop box mechanisms.
Facilitates color or material changes in the weft without halting weaving.
7. Double-Lift Shaft:
Allows two warp threads to lift simultaneously.
Used for complex double-cloth weaving or special effects.
8. Split Shaft:
Divided into sections to handle warp threads differently within the same weave.
Useful for creating differentiated textures or patterns.
These shafts, when combined in various ways, enable
the creation of diverse fabric structures, patterns, and textures.
