Use of heald in weaving machine?

In a weaving machine, a heald (or heddle) is a crucial component that helps in the separation of warp threads. Each heald consists of a wire or cord that holds the warp threads and can be raised or lowered to create a shed, or opening, through which the weft thread can pass. By controlling the movement of multiple healds, different patterns and structures in the woven fabric can be achieved. This mechanism is essential for the efficient and precise production of textiles.
